Gravitational Waves

چکیده
This article reviews current efforts and plans for gravitational-wave detection, the gravitationalwave sources that might be detected, and the information that the detectors might extract from the observed waves. Special attention is paid to (i) the LIGO/VIRGO network of earth-based, kilometer-scale laser interferometers, which is now under construction and will operate in the highfrequency band (1 to 10 Hz), and (ii) a proposed 5-million-kilometer-long Laser Interferometer Space Antenna (LISA), which would fly in heliocentric orbit and operate in the low-frequency band (10 to 1 Hz). LISA would extend the LIGO/VIRGO studies of stellar-mass (M ∼ 2 to 300M⊙) black holes into the domain of the massive black holes (M ∼ 1000 to 10M⊙) that inhabit galactic nuclei and quasars.

Gravitational waves are considered in thermal vacuum state. The amplitude and spectral energy density of gravitational waves are found enhanced in thermal vacuum state compared to its zero temperature counterpart. Therefore, the allowed amount of enhancement depends on the upper bound of WMAP-5 and WMAP-7 for the amplitude and spectral energy density of gravitational waves. The enhancement of ...
متن کاملA Decision between Bayesian and Frequentist Upper Limit in Analyzing Continuous Gravitational Waves
Given the sensitivity of current ground-based Gravitational Wave (GW) detectors, any continuous-wave signal we can realistically expect will be at a level or below the background noise. Hence, any data analysis of detector data will need to rely on statistical techniques to separate the signal from the noise. While with the current sensitivity of our detectors we do not expect to detect any tru...
متن کاملAstrometric and timing effects of gravitational waves
Gravitational wave detection can be done by precision timing of millisecond pulsars, and (with less likelihood) by precision astrometry on distant objects whose light or radio waves pass through gravitational waves on their way to our observatories. Underlying both of these is the relatively simple theory of light propagation in spacetimes with gravitational waves, which is also the basis of in...
متن کاملFast Magnetosonic Waves Driven by Gravitational Waves
The propagation of a gravitational wave (GW) through a magnetized plasma is considered. In particular, we study the excitation of fast magnetosonic waves (MSW) by a gravitational wave, using the linearized general-relativistic hydromagnetic equations. We derive the dispersion relation for the plasma, treating the gravitational wave as a perturbation in a Minkowski background space-time. We show...
متن کاملMonopole gravitational waves from relativistic fireballs driving gamma-ray bursts
Einstein’s General Relativity predicts that pressure, in general stresses, play a similar role to energy density, ǫ = ρc (with ρ being corresponding mass density), in generating gravity. The source of gravitational field, the active gravitational mass density, sometimes referred to as Whittaker’s mass density, is ρgrav = ρ + 3p/c , where p is pressure in the case of an ideal fluid. Whittaker’s ...
متن کاملThe First Detection of Gravitational Waves
This article deals with the first detection of gravitational waves by the advanced Laser Interferometer Gravitational Wave Observatory (LIGO) detectors on 14 September 2015, where the signal was generated by two stellar mass black holes with masses 36 M and 29 M that merged to form a 62 M black hole, releasing 3 M energy in gravitational waves, almost 1.3 billion years ago. We begin by providin...
