Search for Gravitational Waves Associated with Gamma-Ray Bursts Detected by Fermi and Swift During the LIGO-Virgo Run O3b

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1632

We search for gravitational-wave signals associated with gamma-ray bursts detected by the Fermi and Swift satellites during the second half of the third observing run of Advanced L…

The Variability of the Black-Hole Image in M87 at the Dynamical Time Scale

Kaushik Satapathy, Dimitrios Psaltis, Feryal Ozel +235

The black-hole images obtained with the Event Horizon Telescope (EHT) are expected to be variable at the dynamical timescale near their horizons. For the black hole at the center o…

All-sky search for gravitational wave emission from scalar boson clouds around spinning black holes in LIGO O3 data

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1669

This paper describes the first all-sky search for long-duration, quasi-monochromatic gravitational-wave signals emitted by ultralight scalar boson clouds around spinning black hole…

Searches for Gravitational Waves from Known Pulsars at Two Harmonics in the Second and Third LIGO-Virgo Observing Runs

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1694

We present a targeted search for continuous gravitational waves (GWs) from 236 pulsars using data from the third observing run of LIGO and Virgo (O3) combined with data from the se…

Clues on jet behavior from simultaneous radio-X-ray fits of GX339-4

S. Barnier, P. -O. Petrucci, J. Ferreira +9

Understanding the mechanisms of accretion-ejection during X-ray binaries outbursts has been a problem for several decades. It is still not clear yet what controls the spectral evol…

A unified accretion-ejection paradigm for black hole X-ray binaries. VI. Radiative efficiency and radio-X-ray correlation during four outbursts from GX339-4

G. Marcel, J. Ferreira, P-O. Petrucci +9

The spectral evolution of transient X-ray binaries can be reproduced by an interplay between two flows separated at a radius : a standard accretion disk (SAD) in the outer par…
