Book Description
This book provides a concise introduction to the physics of gravitational waves. It is aimed at graduate-level students and PhD scholars. Ever since the discovery of gravitational waves in 2016, gravitational wave astronomy has been adding to our understanding of the universe. Gravitational waves have been detected in the past few years from several transient events such as merging stellar-mass black holes, binary neutron stars, etc. These waves have frequencies in a band ranging from a few hundred hertz to around a kilohertz to which LIGO type instruments are sensitive. LISA will be sensitive to much lower range of frequencies from SMBH mergers. Apart from these cataclysmic burst events, there are innumerable sources of radiation which are continuously emitting gravitational waves of all frequencies. These include a whole mass range of compact binary and isolated compact objects and close planetary stellar entities. This book discusses the gravitational wave background produced in typical frequency ranges from such sources emitting over a Hubble time and the fluctuations in the h values measured in the usual devices. Also discussed are the high-frequency thermal background gravitational radiation from hot stellar interiors and newly formed compact objects. The reader will also learn how gravitational waves provide a testing tool for various theories of gravity, i.e. general relativity and extended theories of gravity, and will be the definitive test for general relativity.

Book Description
Since binary pulsars represent a natural laboratory for testing relativistic field theories, it was interesting to study the problem of two bodies, in a strong field regime. Hence, this book is not only a complete review of the work done on binary pulsars but also, it includes an important step towards a more general solution to the problem of the strong field of two bodies; which is still far beyond the reach of researchers. This is done by modifying Curzon solution to describe the field of binaries. A more general formula for red-shift and Shapiro time delay were derived including additional terms. Also, energy localization and the possibility of gravitational waves emission have been discussed. This book is a good reference for the relativists and astrophysicists. "The book presents a competent and reasonably complete summary of techniques developed for study of binary stars. It summarizes work that has been done on the relativistic two-body problem. The author traces the progressively more accurate models, and reviews what has been learned from detailed timing observations"..........Prof. J.H. Taylor (Nobel laureate in Physics 1993 for the discovery of the first binary pulsar)

Book Description
The focus of his prize-winning thesis is on observations and modeling of binary millisecond pulsars. But in addition, John Antoniadis covers a wide range of observational measurements of binary compact stars systems and tests of General Relativity, like indirect measurements of gravitational wave emission and posing the most stringent constraints on Scalar-Tensor gravity theories. Among others, he presents a system that hosts the most massive neutron star known to date, which has important ramifications for strong-field gravity and nuclear physics. This impressive work was awarded the Otto-Hahn Medal of the Max-Planck Society and the Best PhD in Gravity, Particle and Atomic physics award by the German Physics Society (DPG).

Book Description
General relativity has so far passed all experimental tests, with some of the most stringent tests in strong fields coming from observations of pulsars - rotating neutron stars that form from the collapsed cores of massive stars during supernovae. Such compact objects contain the densest form of matter in the observable universe, and therefore produce a strong gravitational field in their vicinity. The excellent rotational stability of pulsars makes them powerful tools for studying a wide range of topics in fundamental physics. This dissertation investigates four aspects using the new generation of radio telescopes: (1) constraining the dense matter equation of state by measuring the moment of inertia of neutron stars, (2) testing higher-order gravitational light propagation effects in the Double Pulsar system using observations from the MeerKAT telescope, (3) prospects of testing scalar-tensor gravity using pulsar-white dwarf system and hypothetical pulsar-black hole systems, and (4) recent advances in the detection of nanohertz gravitational waves using pulsar timing arrays and efforts to improve it.

Book Description
The 2015 centenary of the publication of Einstein's general theory of relativity, and the first detection of gravitational waves have focused renewed attention on the question of whether Einstein was right. This review of experimental gravity provides a detailed survey of the intensive testing of Einstein's theory of gravity, including tests in the emerging strong-field dynamical regime. It discusses the theoretical frameworks needed to analyze gravitational theories and interpret experiments. Completely revised and updated, this new edition features coverage of new alternative theories of gravity, a unified treatment of gravitational radiation, and the implications of the latest binary pulsar observations. It spans the earliest tests involving the Solar System to the latest tests using gravitational waves detected from merging black holes and neutron stars. It is a comprehensive reference for researchers and graduate students working in general relativity, cosmology, particle physics and astrophysics.
