Book Synopsis The Formation and Disruption of Black Hole Jets by : Ioannis Contopoulos
Download or read book The Formation and Disruption of Black Hole Jets written by Ioannis Contopoulos and published by Springer. This book was released on 2014-11-10 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the phenomenology displayed by relativistic jets as well as the most recent theoretical efforts to understand the physical mechanisms at their origin. Relativistic jets have been observed and studied in Active Galactic Nuclei (AGN) for about half a century and are believed to be fueled by accretion onto a supermassive black hole at the center of the host galaxy. Since the first discovery of relativistic jets associated with so-called "micro-quasars" much more recently, it has seemed clear that much of the physics governing the relativistic outflows in stellar X-ray binaries harboring black holes and in AGN must be common, but acting on very different spatial and temporal scales. With new observational and theoretical results piling up every day, this book attempts to synthesize a consistent, unified physical picture of the formation and disruption of jets in accreting black-hole systems. The chapters in this book offer overviews accessible not only to specialists but also to graduate students and astrophysicists working in other areas. Covered topics comprise Relativistic jets in stellar systems Launching of AGN jets Parsec-scale AGN jets Kiloparsec-scale AGN jets Black hole magnetospheres Theory of relativistic jets The structure and dynamics of the inner accretion disk The origin of the jet magnetic field X-ray observations, phenomenology, and connection with theory
Book Synopsis Virtual Astrophysical Jets by : Silvano Massaglia
Download or read book Virtual Astrophysical Jets written by Silvano Massaglia and published by Springer Science & Business Media. This book was released on 2013-06-05 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings are the result of a three-day meeting held in Oogliani (Italy), on October 2-4 2003, whose title was "VIrtual Astrophysical Jets 2003". Our goal in convening this meeting was to gather some of the scientists among the most active in the field of numerical simulations and modelling of astrophysi cal jets. For keeping the participants close to the "real world", we also invited a few observers to give up-to-date reviews outlining the state-of-the-art of jet observations. The principal aim of the meeting was thus to present and critically discuss the state-of-the-art numerical simulations, analytical models and laboratory ex periments for reproducing the main aspects of astrophysical jets and compar ing them with observations. The discussion has been focused on the following topics: • Observations and intepretions of jets from young stars and AGNs, comparisons of models with observations; • MHO accelerations of jets: steady self-similar models, MHO numerical simula tions of time-dependent accelerations mechanisms; • Jet stability and interaction with the ambient: formation of knots in YSO jets, jet survival to instabilities, deceleration of relativistic jets in FRI sources, simulations of jets-IGM interactions, jets propagation and galaxy formation; • Numerical codes and their validation: relativistic MHO codes, comparisons among different numerical schemes, jets in the laboratory and code validation. These topics have been discussed intensively during the meeting, and the out come of these discussions is presented in this volume. The contributions have been divided in five sections.

Book Synopsis The Jet Paradigm by : Tomaso Belloni
Download or read book The Jet Paradigm written by Tomaso Belloni and published by Springer. This book was released on 2010-05-03 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discovery of the ?rst case of superluminal radio jets in our galaxy in 1994 from the bright and peculiar X-ray source GRS 1915+105 has opened the way to a major shift in the direction of studies of stellar-mass accreting binaries. The past decade has seen an impressive increase in multi-wavelength studies. It is now known that all black hole binaries in our galaxy are radio sources and most likely their radio emission originates from a powerful jet. In addition to the spectacular events related to the ejection of superluminal jets, steady jets are known from many systems. Compared with their supermassive cousins, the nuclei of active galaxies, stellar-mass X-ray binaries have the advantage of varying on time scales accessible within a human life (sometimes even much shorter than a second). This has led to the ?rst detailed studies of the relation between accretion and ejection. It is even possible that, excluding their “soft” periods, the majority of the power in gal- tic sources lies in the jets and not in the accretion ?ows. This means that until a few years ago we were struggling with a physical problem, accretion onto compact objects, without considering one of the most important components of the system. Models that associate part of the high-energy emission and even the fast aperiodic variability to the jet itself are now being proposed and jets can no longer be ignored.
Book Synopsis Jets From Young Stars V by : José Gracia
Download or read book Jets From Young Stars V written by José Gracia and published by Springer. This book was released on 2009-10-30 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studying the complex physical systems of stellar jets necessitates the incorporation of nonlinear effects which occur on a wide variety of length and timescales. One of the primary methods used to study the physics of jets is numerical simulations that apply high performance computing techniques. Such techniques are also required for analysing the huge modern astrophysical datasets. This book examines those computing techniques. It is a collection of the lectures from the fifth and final school of the JETSET network, "Jets From Young Stars V: High Performance Computing in Astrophysics." It begins with an introduction to parallel programming techniques, with an emphasis on Message Passing Interface (MPI), before it goes on to review grid technology techniques and offer a practical introduction to Virtual Observatory. The second half of the book, then, is devoted to applications of high performance computing techniques, including 3D radiation transfer, to jet and star formation processes. Aimed at graduate students in astrophysics, this book presents state-of-the-art methods, thereby offering interesting new insights to researchers in the field.

Book Synopsis Relativistic Jets by : Philip A. Hughes
Download or read book Relativistic Jets written by Philip A. Hughes and published by . This book was released on 2006 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Highly collimated flows of plasma (jets), with speeds comparable to that of light, are a ubiquitous feature of our Universe. While the global dynamics of extragalactic jets is reasonably well understood, their composition and internal structure, and the role of magnetic fields, remain obscure. Major questions remain concerning the physics of the gamma-ray emission itself. This proceedings includes the eight invited talks presented at this conference.
Book Synopsis On the Nature of Emission from Relativistic Jets by : Patrick Kelly Crumley
Download or read book On the Nature of Emission from Relativistic Jets written by Patrick Kelly Crumley and published by . This book was released on 2015 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several longstanding questions in astrophysics center on the make up of relativistic astrophysical jets seen in microquasars, blazars, gamma-ray bursts, and super-Eddington tidal disruption events. What carries the energy in these jets? Is the majority of the energy carried by Poynting flux or by the baryonic matter? How is this energy converted into the non-thermal gamma-rays and X-rays seen in these systems? While there are many different theoretical models for launching a relativistic jet and producing the non-thermal emission observed in these astrophysical systems, often times the observational data are not good enough to convincingly discriminate between models. This thesis is comprised of several different projects that address these questions for several different astrophysical systems. First I discuss some general considerations of the synchrotron radiation from electrons accelerated by magnetic reconnection in a Poynting dominated jet. I show that the super-Eddington tidal disruption events (TDE) represent an unique opportunity to test different emission mechanisms in relativistic jets. I find that a magnetic dominated jet model can most easily explain the broadband observations in the observed super-Eddington TDE Sw J1644+57. In gamma-ray bursts, that hadronic emission models cannot explain the high energy ( >100 MeV) gamma-rays observed by the Fermi Large Area Telescope. I also include a chapter that suggests using the radio monitoring of the diffuse cloud in the galactic center object G2's to distinguish between different models of G2. Early observations of G2 after periapse passage suggests this prediction was correct.

Book Synopsis The Jets and Supercritical Accretion Disk in SS433 by : S. Fabrika
Download or read book The Jets and Supercritical Accretion Disk in SS433 written by S. Fabrika and published by . This book was released on 2004 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes and reviews observations and investigations of the unique object SS433 obtained after 23 years of studying the massive binary system.The main difference between SS433 and other known X-ray binaries is the action of a constant supercritical regime for the accretion of gas onto the relativistic star (most likely a black hole) which has led to the formation of a supercritical accretion disk and collimated relativistic jets. The properties of jets are to a large extent determined by their interaction with disk wind. The precession of the disk and jets as well as the eclipsing in the binary system make SS433 a unique laboratory for studies of mechanisms for the microquasar phenomenon. The author describes the main ideas and results emerging from studies of the formation of the jets and supercritical accretion disk in SS433.

Book Synopsis Relativistic Hydrodynamics by : Luciano Rezzolla
Download or read book Relativistic Hydrodynamics written by Luciano Rezzolla and published by OUP Oxford. This book was released on 2013-09-26 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: Relativistic hydrodynamics is a very successful theoretical framework to describe the dynamics of matter from scales as small as those of colliding elementary particles, up to the largest scales in the universe. This book provides an up-to-date, lively, and approachable introduction to the mathematical formalism, numerical techniques, and applications of relativistic hydrodynamics. The topic is typically covered either by very formal or by very phenomenological books, but is instead presented here in a form that will be appreciated both by students and researchers in the field. The topics covered in the book are the results of work carried out over the last 40 years, which can be found in rather technical research articles with dissimilar notations and styles. The book is not just a collection of scattered information, but a well-organized description of relativistic hydrodynamics, from the basic principles of statistical kinetic theory, down to the technical aspects of numerical methods devised for the solution of the equations, and over to the applications in modern physics and astrophysics. Numerous figures, diagrams, and a variety of exercises aid the material in the book. The most obvious applications of this work range from astrophysics (black holes, neutron stars, gamma-ray bursts, and active galaxies) to cosmology (early-universe hydrodynamics and phase transitions) and particle physics (heavy-ion collisions). It is often said that fluids are either seen as solutions of partial differential equations or as "wet". Fluids in this book are definitely wet, but the mathematical beauty of differential equations is not washed out.
Book Synopsis The Tidal Disruption of Stars by Massive Black Holes by : Peter G. Jonker
Download or read book The Tidal Disruption of Stars by Massive Black Holes written by Peter G. Jonker and published by Springer. This book was released on 2021-11-19 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides an overview of the fast-developing field of tidal disruption events. For several decades, astronomers speculated that a hapless star could wander too close to a massive black hole and be torn apart by tidal forces. Yet it is only with the recent advent of wide-field transient surveys that such events have been detected. Written by a team of prominent researchers, the chapters detail the discoveries made so far in this burgeoning field of study across the entire electromagnetic spectrum, from gamma-rays through X-rays, ultra-violet, optical, infrared, and radio. In addition, they show how tidal disruption events can be used to study the properties of otherwise undetectable supermassive black holes; the populations and dynamics of stars in galactic nuclei; the physics of black hole accretion, including the potential to detect relativistic effects near a SMBH; and the physics of (radio) jet formation and evolution in a pristine environment. Finally, the book outlines important outstanding questions about TDEs. With more than 100 color images, the volume will be useful to researchers and others interested in learning more about this promising area of astrophysics.

Book Synopsis Relativistic Flows in Astrophysics by : A.W. Guthmann
Download or read book Relativistic Flows in Astrophysics written by A.W. Guthmann and published by Springer. This book was released on 2008-01-11 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: 1. 1 Schematic Picture of AGN Some galaxies are known to emit radiation with extremely high luminosities from a rather small volume in the ??ray, X-ray and UV continuum. Such active cores are the so-called Active Galactic Nuclei (AGN) and the radiation is commonly believed to be a result of gravitational energy released by matter spiraling around 9 a supermassive central black hole of about 10 M (see Fig. 1). Though the central engine which produces the enormous observed activity cannot be resolved observationally, a standard picture of an AGN has gradually emerged to explain the richness of the radiation spectra: • an accretion disk with radius from about 2 to 100 gravitational radii, R , g feeding the central black hole and emitting mainly in the UV and soft X-rays; • the broad line optically emitting clouds (BLR), which seem to be absent in 3 some sources (e. g. FRI, see hereafter) and extend up to a few 10 R from g the center.
