Swope Supernova Survey 2017a (SSS17a), the Optical Counterpart to a Gravitational Wave Source

open access: yesScience, 2017
On 2017 August 17, the Laser Interferometer Gravitational-wave Observatory (LIGO) and the Virgo interferometer detected gravitational waves emanating from a binary neutron star merger, GW170817.

Primordial black holes and their gravitational-wave signatures

open access: yesLiving Reviews in Relativity
In the recent years, primordial black holes (PBHs) have emerged as one of the most interesting and hotly debated topics in cosmology. Among other possibilities, PBHs could explain both some of the signals from binary black hole mergers observed in ...

LIGO: the Laser Interferometer Gravitational-Wave Observatory [PDF]

open access: yesReports on Progress in Physics, 2009
The goal of the Laser Interferometric Gravitational-Wave Observatory (LIGO) is to detect and study gravitational waves of astrophysical origin. Direct detection of gravitational waves holds the promise of testing general relativity in the strong-field regime, of providing a new probe of exotic objects such as black hole and neutron stars, and of ...

A CRYSTAL-BASED MATTER-WAVE INTERFEROMETRIC GRAVITATIONAL-WAVE OBSERVATORY [PDF]

open access: greenQuantum Aspects of Beam Physics 2003, 2004
It is shown that atom interferometry allows for the construction of MIGO, the Matter-wave Interferometric Gravitational-wave Observatory. MIGOs of the same sensitivity as LIGO or LISA are expected to be orders of magnitude smaller than either one. A design for MIGO using crystalline diffraction gratings is introduced, and its sensitivity is calculated.

Construction of KAGRA: An underground gravitational-wave observatory [PDF]

open access: greenProgress of Theoretical and Experimental Physics, 2018
Major construction and initial-phase operation of a second-generation gravitational-wave detector KAGRA has been completed. The entire 3-km detector is installed underground in a mine in order to be isolated from background seismic vibrations on the surface.

Space-Based Gravitational WaveObservatories [PDF]

open access: yes, 2021
In this article, which will appear as a chapter in the Handbook of Gravitational Wave Astronomy, we will describe the detection of gravitational waves with space-based interferometric gravitational wave observatories. We will provide an overview of the key technologies underlying their operation, illustrated using the specific example of the Laser ...

Quantum expander for gravitational-wave observatories [PDF]

open access: yesLight: Science & Applications, 2019
AbstractThe quantum uncertainty of laser light limits the sensitivity of gravitational-wave observatories. Over the past 30 years, techniques for squeezing the quantum uncertainty, as well as for enhancing gravitational-wave signals with optical resonators have been invented.

Electromagnetic emission from circumbinary disk of merging black holes [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2021
In the paper a scenario of an electromagnetic response formation from the merging of two black holes is considered. In this scenario it’s assumed that the binary black hole is surrounded by an accretion disk.
