Detection of GW200105 with a targeted eccentric search
Khun Sang Phukon, Patricia Schmidt, Gonzalo Morras +1
The neutron star -- black hole (NSBH) binary GW200105 was recently found to have significant residual orbital eccentricity at a gravitational-wave frequency of 20 Hz~\cite{Morras:2…
Compact Binary Coalescence Sensitivity Estimates with Injection Campaigns during the LIGO-Virgo-KAGRA Collaborations' Fourth Observing Run
Reed Essick, Michael W. Coughlin, Michael Zevin +21
We describe the effort to characterize gravitational-wave searches and detector sensitivity to different types of compact binary coalescences during the LIGO-Virgo-KAGRA Collaborat…
Binary black holes in the heat of merger
Samanwaya Mukherjee, Sayak Datta, Sukanta Bose +1
A black hole binary approaching merger undergoes changes in its inspiral rate as energy and angular momentum are lost from the orbits into the horizons. This effect strengthens as…
Evolution of precessing binary black holes on eccentric orbits using orbit-averaged evolution equations
Khun Sang Phukon, Nathan K. Johnson-McDaniel, Amitesh Singh +1
The most general bound binary black hole (BBH) system has an eccentric orbit and precessing spins. The detection of such a system with significant eccentricity close to the merger…
A geometric template bank for the detection of spinning low-mass compact binaries with moderate orbital eccentricity
Khun Sang Phukon, Patricia Schmidt, Geraint Pratten
Compact binaries on eccentric orbits are another class of gravitational-wave (GW) sources that can provide a wealth of information on binary formation pathways and astrophysical en…
Phenomenological gravitational waveform model of binary black holes incorporating horizon fluxes
Samanwaya Mukherjee, Khun Sang Phukon, Sayak Datta +1
Subjected to the tidal field of its companion, each component of a coalescing black hole binary suffers a slow change in its mass (tidal heating) and spin (tidal torquing) during t…
Analysis of a subsolar-mass compact binary candidate from the second observing run of Advanced LIGO
Gonzalo Morrás, José Francisco Nuño Siles, Juan García-Bellido +8
We perform an exhaustive follow-up analysis of a subsolar-mass (SSM) gravitational wave (GW) candidate reported by Phukon et al. from the second observing run of Advanced LIGO. Thi…
Virgo Detector Characterization and Data Quality: tools
F. Acernese, M. Agathos, A. Ain +491
Detector characterization and data quality studies -- collectively referred to as {\em DetChar} activities in this article -- are paramount to the scientific exploitation of the jo…
Virgo Detector Characterization and Data Quality: results from the O3 run
F. Acernese, M. Agathos, A. Ain +491
The Advanced Virgo detector has contributed with its data to the rapid growth of the number of detected gravitational-wave (GW) signals in the past few years, alongside the two Adv…
Virgo Detector Characterization and Data Quality during the O3 run
F. Acernese, M. Agathos, A. Ain +491
The Advanced Virgo detector has contributed with its data to the rapid growth of the number of detected gravitational-wave signals in the past few years, alongside the two LIGO ins…
The Virgo O3 run and the impact of the environment
F. Acernese, M. Agathos, A. Ain +486
Sources of geophysical noise (such as wind, sea waves and earthquakes) or of anthropogenic noise impact ground-based gravitational-wave interferometric detectors, causing transient…
Towards establishing the presence or absence of horizons in coalescing binaries of compact objects by using their gravitational wave signals
Samanwaya Mukherjee, Sayak Datta, Srishti Tiwari +2
The quest for distinguishing black holes (BH) from horizonless compact objects using gravitational wave (GW) signals from coalescing compact binaries can be helped by utilizing the…
Imprint of black hole area quantization and Hawking radiation on inspiraling binary
Sayak Datta, Khun Sang Phukon
We study the potential of gravitational wave astronomy to observe the quantum aspects of black holes. According to Bekenstein's quantization, we find that black hole area discretiz…
Recognizing black holes in gravitational-wave observations: Challenges in telling apart impostors in mass-gap binaries

The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1186
We present the results of a search for short-duration gravitational-wave transients in the data from the second observing run of Advanced LIGO and Advanced Virgo. We search for gra…
Effect of orbital eccentricity on the dynamics of precessing compact binaries

Kabir Chakravarti, Sumanta Chakraborty, Khun Sang Phukon +2
We derive the modifications introduced by extra-spatial dimensions beyond the four dimensional spacetime on the macroscopic properties of neutron stars, which in turn affect the gr…
