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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis is devoted to ANTARES, the first underwater neutrino telescope in the Mediterranean sea. As the main scientific analysis, a search for high-energy neutrino emission from the region of the Fermi bubbles has been performed using data from the ANTARES detector. A method for the background estimation using off-zones has been developed specially for this measurement. A new likelihood for the limits calculation which treats both observations in the on-zone and in the off-zone in the similar way and also includes different systematic uncertainties has been constructed. The analysis of 2008–2011 ANTARES data yielded a 1.2 σ excess of events in the Fermi bubble regions, compatible with the no-signal hypothesis. For the optimistic case of no energy cutoff in the flux, the upper limit is within a factor of three of the prediction of the purely hadronic model based on the measured gamma-ray flux. The sensitivity improves as more data are accumulated (more than 65% gain in the sensitivity is expected once 2012–2016 data are added to the analysis).

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astroparticle physics is a branch of physics related to the study of the most violent astrophysical phenomena in the Universe such as Active Galactic Nuclei (AGN) or Gamma Ray Bursts (GRB), which emit different cosmic messengers such as neutrinos, gravitational waves, electromagnetic radiation and charged particles. A proper understanding of these objects involves then a multi-messenger approach, in which neutrinos play a fundamental role. Thanks to their physical properties, neutrinos allow us to explore the physical phenomena produced in the densest astrophysical environments and to observe the Universe at large distances. This thesis is divided into three main parts. The first part is composed by three chapters dedicated to the scientific context in which the rest of the thesis is developed. In the first chapter, the scientific motivations for the search of high energy cosmic neutrinos are described. In chapter 2, a description of the main properties of AGN are given. These sources have been chosen as "test" objects in the research of potential neutrino sources. Finally, the third chapter is dedicated to the detection principle and main results of the currently operating neutrino telescopes. The second part of the thesis is dedicated to the technical description of the ANTARES neutrino telescope, and composed of two chapters. Chapter 4 describes the ANTARES telescope, the data acquisition and the data selection. In the last part of this chapter, the work made to measure the efficiency loss of the photomultipliers (PMTs) by using the baseline rates is described. Chapter 5 is dedicated to the Monte Carlo simulations. The different simulation packages used by the ANTARES collaboration are presented, and the different simulated processes are described. A contribution to the official package for the generation of neutrino interactions, relative to the implementation of the propagation and decay of the tau leptons, is described. The third part is dedicated to the search of potential cosmic signals in the events recorded by ANTARES. It comprises four chapters. Chapter 6 is a description of the signal search method, chapter 7 presents the principles of an analysis based on a 2 point correlation function that will be applied in chapter 9 with the purpose of searching for an excess of cosmic neutrinos characterized by an expected spatial distribution which is different from that of atmospheric neutrinos. This method is well suited for the detection of the collective effect produced by populations of weak point-like sources. Chapter 8 describes the simulation of the neutrino flux emitted by AGN. By using the luminosity function for different AGN classes obtained from X-ray observations, and the ANTARES acceptance, neutrinos coming from AGN populations are simulated as a function of two parameters which are related to the number of sources in the population, and to their luminosities. The analysis of these populations with the 2 point correlation function is detailed in chapter 9.

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: "The identification of cosmic objects emitting high energy neutrinos provides new insights about the Universe and its active sources. The existence of cosmic neutrinos has been proven by the IceCube collaboration, but the big question of which sources these neutrinos originate from remains largely unanswered. The KM3NeT detector for Astroparticle Research with Cosmics in the Abyss (ARCA), is currently being built in the Mediterranean Sea. In its full configuration with > 105 photomultiplier tubes installed it will have an instrumented volume of a cubic kilometre, and excel at identifying cosmic neutrino sources due to its unprecedented angular resolution ( 0.1 degree for muon neutrinos with E 20 TeV). KM3NeT has a view of the sky complementary to IceCube, and is sensitive to neutrinos across a wide range of energies. This dissertation presents the results of the first ever performed point source search with KM3NeT/ARCA with all available processed 2021-2022 data taken with an evolving detector geometry. The analysis did not show a significant excess of neutrinos for the searched candidate sources, but as the detector will grow, and it will keep accumulating data, the sensitivity will improve very fast. Especially in the southern hemisphere, where IceCube has less sensitivity due to its position at the South Pole, KM3NeT/ARCA may add an important contribution in the future of astroparticle physics."--

Download or read book Multi-wavelength Follow-up of ANTARES Neutrino Alerts written by Aurore Mathieu and published by . This book was released on 2016 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transient sources are often associated with the most violent phenomena in the Universe, where the acceleration of hadrons may occur. Such sources include gamma-ray bursts (GRBs), active galactic nuclei (AGN) or core-collapse supernovae (CCSNe), and are promising candidates for the production of high energy cosmic rays and neutrinos. The ANTARES telescope, located in the Mediterranean sea, aims at detecting these high energy neutrinos, which could reveal the presence of a cosmic ray accelerator. However, to enhance the sensitivity to transient sources, a method based on multi-wavelength follow-up of neutrino alerts has been developed within the ANTARES collaboration. This program, denoted as TAToO, triggers a network of robotic optical telescopes and the Swift-XRT with a delay of only few seconds after a neutrino detection. The telescopes start an observation program of the corresponding region of the sky in order to detect a possible electromagnetic counterpart to the neutrino event. The works presented in this thesis cover the development and implementation of an optical image analysis pipeline, as well as the analysis of optical and X-ray data to search for fast transient sources, such as GRB afterglows, and slowly varying transient sources, such as CCSNe.
