Gravity's fatal attraction : black holes in the universe by Mitchell C Begelman( Book )

30 editions published between 1995 and 2010 in English and held by 1,786 WorldCat member libraries worldwide

Black holes are an extraordinary construct, proposed by theorists and embraced by the popular imagination. They represent a mysterious, unexplored frontier where time and space behave in bizarre ways. In essence, black holes are an idea written, spoken, and thought about, but a fundamental question has always remained: Do black holes exist? Astrophysicists Mitchell Begelman and Martin Rees answer this question with a resounding yes. Central participants in the quest to understand black holes, they describe the great technological advances that have allowed scientists to gather compelling evidence that black holes are a real and ubiquitous phenomenon. These points where gravity is infinitely strong, "swallowing" everything in its vicinity, could number in the millions in every galaxy, as the remnants of ordinary stars several times more massive than the Sun. More remarkably, discoveries made early in 1995 supply conclusive evidence that giant black holes, perhaps weighing as much as billions of suns, are lurking at the very center of most galaxies. Gravity's Fatal Attraction: Black Holes in the Universe tracks the observations and accidents through which scientists discovered black holes and the related phenomena they power, such as quasars and dazzling jets a million light-years long. Scientists are just beginning to understand the exotic ways these invisible objects manifest themselves, and how they relate to other structures in the cosmos. Yet, new questions continue to arise: Could microscopic holes exist, the size of an atomic nucleus but the weight of a mountain? As the Universe evolves, could it be the ultimate fate of all matter to be "swallowed" by black holes? As Begelman and Rees point out, the cosmic "fireworks" scientists are investigating may prove most valuable as stepping-stones to even more profound knowledge. The quest to find black holes and related structures, and to understand the mysterious work of gravity within them, could ultimately confirm or refute our theories describing the physical laws of the Universe, and even help us understand its origins and final fate
Turn right at Orion : travels through the cosmos by Mitchell C Begelman( Book )

15 editions published between 2000 and 2009 in English and Chinese and held by 439 WorldCat member libraries worldwide

"Turn Right at Orion is the account of an epic astronomical journey, a tale told by an early-twenty-first century human sailor among the stars. It is discovered, as an alien "translator's note" reveals, 60 million years in earth's future - the product of one man's amazing, revelatory, and occasionally perilous space odyssey." "We travel to the center of the Milky Way, witness the births and deaths of stars, the creation of planets, almost perish in the crushing forces at the perimeter of a black hole - and all the while Begelman explains in clear and vibrant prose how things work the way they do in the cosmos. Turn Right at Orion is serious science that reads like fiction."--Jacket

The Evolutionary Pathways of Tidal Disruption Events: From Stars to Debris Streams, Accretion Disks, and Relativistic Jets by E. R Coughlin( )

1 edition published in 2016 in English and held by 2 WorldCat member libraries worldwide

Tidal disruption events, which occur when a star is destroyed by the gravitational field of a supermassive black hole, are unique probes of the inner regions of galaxies. In this thesis we explore various stages of the tidal disruption process, in an attempt to relate the observable signatures of tidal disruption events to the properties of the disrupted star and the black hole. We use numerical techniques to study the long-term evolution of the debris streams produced from tidal disruption events, showing that they can be gravitationally unstable and, as a result of the instability, fragment into small-scale, localized clumps. The implications of this finding are discussed, and we investigate how the thermodynamic properties of the gas comprising the stream affect the nature of the instability. We derive an analytic model for the structure of tidally-disrupted, stellar debris streams, and we compare the predictions of our model to numerical results. We present a model for the accretion disk that forms from a tidal disruption event when the accretion rate surpasses the Eddington limit of the supermassive black hole, showing that these disks are puffed up into quasispherical envelopes that are threaded by bipolar, relativistic jets. We compare the predictions of this model to observations of the jetted tidal disruption event Swift J1644+57. Finally, we derive, from the relativistic Boltzmann equation, the general relativistic equations of radiation hydrodynamics in the viscous limit, which characterize the interaction between radiation and matter when changes in the fluid over the photon mean free path are small. Our results demonstrate that, in contrast to previous works, a radiation-dominated fluid does in fact possess a finite bulk viscosity and a correction to the comoving energy density. Using the general relativistic equations of radiation hydrodynamics in the viscous limit, we present two models to describe the interaction between a relativistic jet launched during a tidal disruption event and its surroundings. These models show that regions of very large shear that arise between the fast-moving out ow and the surrounding envelope possess fewer scatterers and a harder photon spectrum, meaning that observers looking "down the barrel of the jet" infer vastly different properties of the outflow than those who look off-axis
Causality and Communication: Relativistic astrophysical jets and the implementation of science communication training in astronomy classes by Susanna Kohler( )

1 edition published in 2014 in English and held by 2 WorldCat member libraries worldwide

Part I: Relativistic jets emitted from the centers of some galaxies (called active galaxies) exhibit many interesting behaviors that are not yet fully understood: acceleration and collimation over vast distances, for instance, and occasional flaring activity. In the first part of my thesis, I examine the possibility of collimation and acceleration of relativistic jets by the pressure of the ambient medium surrounding the jet base. I discuss the differences in predicted jet behavior due to including the effects of a magnetic field threading the jet interior, and I describe the conditions that create some observed jet shapes, such as the "hollow cone" structure seen in M87 and similar jets. I also discuss what happens when the pressure outside of the jet drops so slowly that the jet shocks repeatedly, generating entropy at its boundary. Finally, I examine the spectra of the 40 brightest gamma-ray flares from blazars (active galaxies with jets pointed toward us) recorded by the Fermi Gamma-ray Space Telescope in its first four years of operation. I develop models to describe the observed behavior of these flares and discuss the physical implications of these models

Are Quasar Jets Matter Or Poynting Flux Dominated?( )

1 edition published in 2005 in English and held by 0 WorldCat member libraries worldwide

If quasar jets are accelerated by magnetic fields but terminate as matter dominated, where and how does the transition occur between the Poynting-dominated and matter-dominated regimes? To address this question, we study constraints which are imposed on the jet structure by observations at different spatial scales. We demonstrate that observational data are consistent with a scenario where the acceleration of a jet occurs within 10{sup 3-4}R{sub g}. In this picture, the non-thermal flares--important defining attributes of the blazar phenomenon--are produced by strong shocks formed in the region where the jet inertia becomes dominated by matter. Such shocks may be formed due to collisions between the portions of a jet accelerated to different velocities, and the acceleration differentiation is very likely to be related to global MHD instabilities
