Parameters estimation and strong gravitational lensing of nonsingular Kerr-Sen black holes
Sushant G. Ghosh, Rahul Kumar, Shafqat Ul Islam
The recent time witnessed a surge of interest in strong gravitational lensing by black holes is due to the Event Horizon Telescope (EHT) results, which suggest comparing the black…
Cryogenic suspension design for a kilometer-scale gravitational-wave detector
Takafumi Ushiba, Tomotada Akutsu, Yoichi Aso +43
We report the mirror suspension design for Large-scale Cryogenic Gravitational wave Telescope, KAGRA, during bKAGRA Phase 1. Mirror thermal noise is one of the fundamental noises f…
Sensitivity and Performance of the Advanced LIGO Detectors in the Third Observing Run
LIGO Instrument Science List, :, A. Buikema +197
On April 1st, 2019, the Advanced Laser Interferometer Gravitational-Wave Observatory (aLIGO), joined by the Advanced Virgo detector, began the third observing run, a year-long dedi…
Improving the Robustness of the Advanced LIGO Detectors to Earthquakes
Eyal Schwartz, A Pele, J Warner +196
Teleseismic, or distant, earthquakes regularly disrupt the operation of ground--based gravitational wave detectors such as Advanced LIGO. Here, we present \emph{EQ mode}, a new glo…
Testing Rotating Regular Metrics as Candidates for Astrophysical Black Holes
Rahul Kumar, Amit Kumar, Sushant G. Ghosh
The Event Horizon Telescope, a global submillimeter wavelength very long baseline interferometry array, produced the first image of supermassive black hole M87* showing a ring of d…
Phase transition of AdS black holes in 4D EGB gravity coupled to nonlinear electrodynamics
Sushant G. Ghosh, Dharm Veer Singh, Rahul Kumar +1
Einstein-Gauss-Bonnet (EGB) gravity is an outcome of quadratic curvature corrections to the Einstein-Hilbert gravity action in the form of a Gauss-Bonnet (GB) term in dime…
