Available in PDF, EPUB and Kindle. Book excerpt: A century after their discovery, the origin of cosmic rays remains one of the most enduring mysteries in physics. They can have energies that exceed 1020 eV, a hundred million times as energetic as the most powerful Earth-bound particle accelerators and must therefore be produced in the universe's most violent environments. Direct observation of their origins, however, has proven difficult due to deflection of charged cosmic ray particles in galactic and intergalactic magnetic fields, obscuring their true origins. Astronomy using electrically neutral particles, such as photons and neutrinos, does not, however, share this difficulty. This work presents a search for neutrino emission from one of the primary candidates for the sources of the highest-energy cosmic rays, Gamma-Ray Bursts, using the recently-completed IceCube neutrino telescope located at the South Pole. The null result obtained from this search contradicts well-established predictions for the neutrino flux from Gamma-Ray Bursts if they are the cosmic ray sources, forcing a reevaluation of these theoretical models.

This book was released on 2020-10-23 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract Gamma-ray bursts (GRBs) are the most luminous transient events in the observed Universe. However, there is no direct observational evidence for what exactly drives a GRB. The most widely accepted model for these cosmic events is the fireball model where it is thought that a substantial fraction of the kinetic energy of the source is converted to gamma-radiation by shock accelerated electrons emitting synchrotron and inverse-Compton radiation. The acceleration of protons in the gamma-ray emitting region of the GRB has been hypothesized as well. In this hadronic acceleration model, it is predicted that protons may interact with gamma-ray photons to produce a burst of neutrinos at energy ∼10^14 eV during prompt emission and energy ∼10^18 eV during afterglow emission. Several experimental searches for these high energy neutrinos have been conducted and no GRB neutrinos have yet been found. The analytical prediction for neutrino flux has been replaced with a more thorough numerical prediction for neutrino flux. The neutron model of GRBs, where only neutrons can escape the GRB and reach Earth as cosmic rays, has been ruled out by the experimental work of IceCube and ANTARES. Upgraded versions of current experiments such as IceCube, ANTARES, ANITA and ARA, as well as new experiments such as KM3NeT, are preparing to probe and further constrain the fireball paradigm of GRB neutrino production. This review includes: Introduction Early theoretical predictions for neutrino fluences due to GRBs Overview of high energy neutrino experiments and related physics Experimental searches for high energy neutrinos from GRBs Prospects for detection of high energy neutrinos from GRBs High Energy Neutrinos from Gamma Ray Bursts: Theoretical Predictions, Experimental Searches, and Prospects for Detection was originally written as a review submitted for my Ph.D. candidacy paper on Nov 23, 2015.

Book excerpt: We will review the scientific case for neutrino astronomy. It has been made since the 1950's by pioneers who realized that, of all high-energy particles, only neutrinos can directly convey astrophysical information from the edge of the Universe and from deep inside its most cataclysmic high-energy regions near black holes. With the Antarctic Muon And Neutrino Detector Array (AMANDA), we have performed the first scans of the sky using neutrinos of TeV-energy and above as cosmic messengers. We will discuss the search for neutrino emission from gamma-ray bursts and active galaxies, which are known sources of high-energy gamma-rays. We searched with improved sensitivity for magnetic monopoles, and for a cold dark matter signal from the center of the Earth. Most importantly, by observing neutrinos produced by cosmic rays in the Earth's atmosphere we present a proof of concept for an expandable technology with which to build the ultimate kilometer-scale neutrino observatory, IceCube.

Book excerpt: Neutrino astronomy began with the detection of solar neutrinos, supernova neutrinos(SN1987A) and more recently the 37 events in IceCube which are very likelyto be an astrophysical origin. The result from IceCube is perhaps the most excitingdiscovery of the year 2013, capping a several decades long search. Variousastrophysical candidates have been proposed as sources of high energy neutrinos,although the origin of the IceCube neutrinos remains a mystery. Gamma-raybursts (GRBs), the most energetic explosions in the universe, were considered asthe most promising source for high energy cosmic rays and neutrinos (with AGNs).However, a previous search of GRB neutrinos by IceCube surprised the GRB communitywith negative results, challenging the simple standard picture of GRBprompt emission which is called the \internal shock" model. In this thesis we givea closer investigation of this model as well as several leading alternative models.With a careful consideration of the particle physics and the model parameters weshow that the previous negative result with GRB neutrinos is not surprising, andonly those models with extremely optimistic parameters can be ruled out. Wepredict that GRBs are unlikely to be the sole sources of the IceCube events, butsignals of GRB neutrinos may be detected in the near future, with the neutrinotelescopes such as IceCube/DeepCore, KM3Net, ARA, ARIANNA, ANITA etc.

Download or read book High Energy Astrophysical Neutrinos written by Debanjan Bose and published by Springer Nature. This book was released on 2021-12-07 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a pedagogical introduction to the likely sources of these neutrinos, their propagation and detection mechanisms. Detection of high energy neutrinos of extragalactic origin has led to an interdisciplinary field of research, involving astronomy, astrophysics and particle physics. An extensive review of various detectors and the observations is provided that consolidates the latest findings. Above a few tens of TeVs, neutrinos are conceived as more reliable messengers for astronomy than photons as these photons get absorbed in the background photon field. Determining the neutrino spectrum not only helps in exploring astrophysical objects like AGN, GRB, etc. but also allows us to study particle physics at unprecedented energies. This introductory book is intended to help advanced undergraduate and graduate students to get into the subject with ease, and it simultaneously caters to practicing theoretical or experimental physicists as a reference book.

Available in PDF, EPUB and Kindle. Book excerpt: High-energy neutrinos from Gamma-Ray Bursts (GRBs) have been expected since the pre-Swift era. Such signals may be detected by future large neutrino detectors such as IceCube. Recently Swift has shown several novel phenomena. We suggest the new prospects for high-energy neutrino emission in the Swift era. Expected signals, if detected, are useful for revealing of the nature of GRBs.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neutrinos are unique messengers for detecting violent phenomena in the Universe. Potential sources of cosmic neutrinos are, for example, Active Galactic Nuclei (AGNs) or Gamma-Ray Bursts (GRBs). In the case of hadronic cosmic rays acceleration, the production of neutrinos is possibly accompanied by high-energy gamma-ray emissions. The search for coincidences between high-energy neutrinos detected by the ANTARES neutrino telescope and gamma-rays detected by the HAWC gamma-ray observatory is presented. Searching in a particular time window significantly reduces the background noise in the neutrino data and thus increases the discovery potential. In this thesis, the results of a search for neutrinos detected in correlation with a gamma-ray signal from two particular AGNs, Markarian 421 and Markarian 501, are presented. As the blazars closest to Earth, they are excellent sources for testing the blazar-neutrino connection scenario, especially during the increase of their activities (flares) in which the search for neutrinos may have a higher detection probability.

This book was released on 2012 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ANTARES collaboration has successfully built, deployed and is currently operating an underwater Cherenkov detector dedicated to high energy neutrino astronomy. The primary aim of the experiment is to detect cosmic sources of neutrinos in order to reveal the production sites of cosmic rays. Among the sources likely to be significant sources of neutrinos are those accelerating relativistic jets, like gamma ray bursts, active galactic nuclei and microquasars. Microquasars are binary systems formed by a compact object accreting mass from a companion star. The mass transfer causes the emission of X-rays, whereas the onset of magnetic forces in the accreting plasma can cause the acceleration of relativistic jets, which are observed by radio telescopes via their non-thermal synchrotron emission. In some systems, a correlation between X-ray and radio light curves indicates an interplay between accretion and ejection respectively. Some microquasars are also high energy and very high energy gamma ray emitters. In this thesis, a time dependent search for neutrino emission from microquasars was performed with a multi-messenger approach (photon/neutrino). The data from the X-ray monitors RXTE/ASM and SWIFT/BAT, and the gamma-ray telescope FERMI/LAT were used to select transient events in which the source was supposed to accelerate relativistic jets. The restriction of the analysis to the ejection periods allows a drastic reduction of atmospheric muon and neutrino background, and thus to increase the chances of a discovery. The search was performed with the ANTARES data taken between 2007 and 2010.
Book Synopsis Search for GRB Neutrino Emission According to the Photospheric Model with the ANTARES Telescope by : Matteo Sanguineti

This book was released on 2016 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: The possible evidence of neutrino emission in correspondence of a Gamma ray burst (GRB) would gave important informations on the production mechanisms and on the most promising emission models. Among these, one of the most recent and widely discussed is the so-called photospheric model. It can explain some measured features of the gamma ray bursts that are not described by the previous models. The photospheric model predicts a sensible neutrino emission in an energetic range a couple of order of magnitude lower with respect to the classical models. In this thesis a completely innovative method of research has been proposed and dedicated tools have been developed to enhance the ANTARES detector sensitivity in the energetic range predicted by the photospheric model. To this extent, for the first time, the unflitered data registered in ANTARES in correspondence of a gamma ray burst has been used. In addition a dedicated directional trigger and a special reconstruction algorithm optimized at low energies were found very effective. As a result, this analysis has enhanced the sensitivity of the dectector up to a factor 2 for neutino energies between 100 GeV and 1 TeV. This analysis was applied to the search of a possible neutrino emission in correspondance of the GRB130427A and GRB130505A events. No evidence for neutrino emission was found. However an upper limit on the neutrino flux from these GRBs in the energetic range which fats the predictions of the most recent emission models was determined.
Book Synopsis High Energy Neutrinos and Cosmic-Rays From Low-Luminosity Gamma-Ray Bursts? by : Takashi Nakamura
Download or read book High Energy Neutrinos and Cosmic-Rays From Low-Luminosity Gamma-Ray Bursts? written by Takashi Nakamura and published by . This book was released on 2006 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recently discovered gamma-ray burst (GRB) 060218/SN 2006aj is classified as an X-ray Flash with very long duration driven possibly by a neutron star. Since GRB 060218 is very near {approx} 140 Mpc and very dim, one-year observation by Swift suggests that the true rate of GRB 060218-like events might be very high so that such low luminosity GRBs (LL-GRBs) might form a different population of GRBs from the cosmological high luminosity GRBs (HL-GRBs). We found that the high energy neutrino background from such LL-GRBs could be comparable with or larger than that from HL-GRBs. If each neutrino event is detected by IceCube, later optical-infrared follow-up observations such as by Subaru could identify a Type Ibc supernova associated with LL-GRBs, even if gamma- and X-rays are not observed by Swift. This is in a sense a new window from neutrino astronomy, which might enable us to confirm the existence of LL-GRBs and to obtain information about their rate and origin. We also argue LL-GRBs as high energy gamma-ray and cosmic-ray sources.

Available in PDF, EPUB and Kindle. Book excerpt: We present the results of searches for high-energy muon neutrinos from 41 gamma- ray bursts (GRBs) in the northern sky with the IceCube detector in its 22-string con-figuration active in 2007/2008. The searches cover both the prompt and a possible precursor emission as well as a model-independent, wide time window of -1 h to +3 haround each GRB. In contrast to previous searches with a large GRB population, we do not utilize a standard Waxman?Bahcall GRB flux for the prompt emission but calcu- late individual neutrino spectra for all 41 GRBs from the burst parameters measured by satellites. For all three time windows the best estimate for the number of signal events is zero. Therefore, we place 90percent CL upper limits on the fluence from the prompt phase of 3.7 x 10-3 erg cm-2 (72TeV - 6.5 PeV) and on the fluence from the precursor phase of 2.3 x 10-3 erg cm-2 (2.2TeV - 55TeV), where the quoted energy ranges contain 90percent of the expected signal events in the detector. The 90percent CL upper limit for the wide time window is 2.7 x 10-3 erg cm-2 (3TeV - 2.8 PeV) assuming an E-2 flux.

This book was released on 2019-12-17 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses three “hot” topics concerning the general problem of the origin of Galactic cosmic rays, namely (1) the acceleration, propagation, and radiation of particles in supernova remnants; (2) very high energy neutrinos from the Galactic Center; and (3) the potential held by the next-generation gamma-ray and neutrino detectors CTA and KM3NeT for studying extended non-thermal sources in the Galaxy. The topics are intrinsically connected to determining the nature (“hadronic or leptonic?”) of gamma-ray emissions from young and middle-aged supernova remnants and the search for cosmic-ray PeVatrons. The results and conclusions provided here are based on extensive analytical and numerical simulations, which are formulated and presented in a straightforward format that can be readily used in the interpretations of gamma-ray and neutrino observations, as well as for confident predictions for future measurements.
