S. Abe, J. Abhir, A. Abhishek +457
The detection of gravitational waves (GWs) from a binary neutron star (BNS) merger by Advanced LIGO and Advanced Virgo (GW170817), together with its electromagnetic counterpart, th…
NICER observations reveal doubled timescales in Ansky's quasi-periodic eruptions (QPEs)
L. Hernández-GarcÃa, P. Sánchez-Sáez, J. Chakraborty +11
Quasi-periodic eruptions (QPEs) are recurring X-ray bursts originating from the vicinity of supermassive black holes, but their driving mechanisms remain under debate. This study a…
The Compton-thick AGN Population and the Distribution of Low-mass AGN in our Cosmic Backyard
A. Annuar, D. M. Alexander, P. Gandhi +21
We present a census of the Compton-thick (CT) active galactic nucleus (AGN) population and the column density () distribution of AGN in our cosmic backyard using a mid-…
Tuning into spatial frequency space: Satellite and space debris detection in the ZTF alert stream
J. P. Carvajal, F. E. Bauer, I. Reyes-Jainaga +6
A significant challenge in the study of transient astrophysical phenomena is the identification of bogus events, among which human-made satellites and debris in Earth orbit remain…
