Book excerpt: Over the last six years, the LIGO and Virgo gravitational wave detectors have revolutionized gravitational wave astronomy by discovering the first compact binary mergers. There is much to learn about how these systems form in nature, and these discoveries have allowed to start characterizing the astrophysical population of binary black holes. Many layers of data processing are needed in the path from raw gravitational wave data to inference of astrophysical implications. In this thesis, I worked on algorithms to search for signals from compact binary mergers, estimating their parameters and analyzing them collectively to infer properties of the astrophysical population, aimed at key questions in gravitational wave astronomy: What is the rate of binary mergers in the Universe? What is the distribution of masses and spins? What is the formation mechanism of merging binary black holes?I construct a bank of waveform templates suitable for searching compact binary mergers in gravitational wave data through matched-filtering. The resulting bank is defined on a geometric space, whose notion of distance between waveforms naturally corresponds to their response mismatch. Beyond aiding intuition, this feature enables optimal placement of templates, dynamical refinement of the search, and powerful and robust signal quality tests. Using this template bank, my collaborators and I carried out a search for binary black holes in public LIGO-Virgo data, confirming previous detections and identifying nine new events.I compute the likelihood function for the parameters of the individual sources, such as black hole masses and spins. I derive a framework to combine these pieces of information into a likelihood for the collective distribution of these parameters, that accounts for measurement uncertainties, selection effects and statistical significance of the events. With this, I test and constrain phenomenological models for the distribution of binary black hole masses, spins, merger rates and cosmological evolution. I find that the mass distribution features a steep drop around 40 solar masses, as predicted by the pair-instability supernova mechanism; but also features an extended tail to higher masses. The distribution of spin orientations is anisotropic, disfavoring dynamical formation channels as the only pathway for merging binary black holes.
Book Synopsis Relativistic Celestial Mechanics of the Solar System by : Sergei Kopeikin
Download or read book Relativistic Celestial Mechanics of the Solar System written by Sergei Kopeikin and published by John Wiley & Sons. This book was released on 2011-10-25 with total page 897 pages. Available in PDF, EPUB and Kindle. Book excerpt: This authoritative book presents the theoretical development of gravitational physics as it applies to the dynamics of celestial bodies and the analysis of precise astronomical observations. In so doing, it fills the need for a textbook that teaches modern dynamical astronomy with a strong emphasis on the relativistic aspects of the subject produced by the curved geometry of four-dimensional spacetime. The first three chapters review the fundamental principles of celestial mechanics and of special and general relativity. This background material forms the basis for understanding relativistic reference frames, the celestial mechanics of N-body systems, and high-precision astrometry, navigation, and geodesy, which are then treated in the following five chapters. The final chapter provides an overview of the new field of applied relativity, based on recent recommendations from the International Astronomical Union. The book is suitable for teaching advanced undergraduate honors programs and graduate courses, while equally serving as a reference for professional research scientists working in relativity and dynamical astronomy. The authors bring their extensive theoretical and practical experience to the subject. Sergei Kopeikin is a professor at the University of Missouri, while Michael Efroimsky and George Kaplan work at the United States Naval Observatory, one of the world?s premier institutions for expertise in astrometry, celestial mechanics, and timekeeping.

Book Synopsis The Black Hole-Neutron Star Binary Merger in Full General Relativity by : Koutarou Kyutoku
Download or read book The Black Hole-Neutron Star Binary Merger in Full General Relativity written by Koutarou Kyutoku and published by Springer Science & Business Media. This book was released on 2013-01-11 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a systematic study of the orbital evolution, gravitational wave radiation, and merger remnant of the black hole–neutron star binary merger in full general relativity for the first time. Numerical-relativity simulations are performed using an adaptive mesh refinement code, SimulAtor for Compact objects in Relativistic Astrophysics (SACRA), which adopts a wide variety of zero-temperature equations of state for the neutron star matter. Gravitational waves provide us with quantitative information on the neutron star compactness and equation of state via the cutoff frequency in the spectra, if tidal disruption of the neutron star occurs before the binary merges. The cutoff frequency will be observed by next-generation laser interferometric ground-based gravitational wave detectors, such as Advanced LIGO, Advanced VIRGO, and KAGRA. The author has also determined that the mass of remnant disks are sufficient for the remnant black hole accretion disk to become a progenitor of short-hard gamma ray bursts accompanied by tidal disruptions and suggests that overspinning black holes may not be formed after the merger of even an extremely spinning black hole and an irrotational neutron star.

Book Synopsis Understanding Gravitational Waves by : C. R. Kitchin
Download or read book Understanding Gravitational Waves written by C. R. Kitchin and published by Springer Nature. This book was released on 2021-09-23 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: The birth of a completely new branch of observational astronomy is a rare and exciting occurrence. For a long time, our theories about gravitational waves—proposed by Albert Einstein and others more than a hundred years ago—could never be fully proven, since we lacked the proper technology to do it. That all changed when, on September 14, 2015, instruments at the LIGO Observatory detected gravitational waves for the first time. This book explores the nature of gravitational waves—what they are, where they come from, why they are so significant and why nobody could prove they existed before now. Written in plain language and interspersed with additional explanatory tutorials, it will appeal to lay readers, science enthusiasts, physical science students, amateur astronomers and to professional scientists and astronomers.

Download or read book The Modern Myths written by Philip Ball and published by University of Chicago Press. This book was released on 2022-10-17 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: With The Modern Myths, brilliant science communicator Philip Ball spins a new yarn. From novels and comic books to B-movies, it is an epic exploration of literature, new media and technology, the nature of storytelling, and the making and meaning of our most important tales. Myths are usually seen as stories from the depths of time—fun and fantastical, but no longer believed by anyone. Yet, as Philip Ball shows, we are still writing them—and still living them—today. From Robinson Crusoe and Frankenstein to Batman, many stories written in the past few centuries are commonly, perhaps glibly, called “modern myths.” But Ball argues that we should take that idea seriously. Our stories of Dracula, Dr. Jekyll and Mr. Hyde, and Sherlock Holmes are doing the kind of cultural work that the ancient myths once did. Through the medium of narratives that all of us know in their basic outline and which have no clear moral or resolution, these modern myths explore some of our deepest fears, dreams, and anxieties. We keep returning to these tales, reinventing them endlessly for new uses. But what are they really about, and why do we need them? What myths are still taking shape today? And what makes a story become a modern myth? In The Modern Myths, Ball takes us on a wide-ranging tour of our collective imagination, asking what some of its most popular stories reveal about the nature of being human in the modern age.
