Neutron stars and stellar-mass black holes are the remnants of massive star explosions.
Most massive stars reside in close binary systems, and the interplay between the companion …

In recent years, certain luminous extragalactic optical transients have been observed to last
only a few days. Their short observed duration implies a different powering mechanism from …

Rapid strides are currently being made in the field of artificial intelligence using transformer-
based models like Large Language Models (LLMs). The potential of these methods for …

We report observations of the optical counterpart of the long gamma-ray burst (GRB) GRB
230812B and its associated supernova (SN) SN 2023pel. The proximity (z= 0.36) and high …

We present observations of SN 2022joj, a peculiar Type Ia supernova discovered by the
Zwicky Transient Facility. SN 2022joj exhibits an unusually red g ZTF− r ZTF color at early …

Optical surveys have become increasingly adept at identifying candidate tidal disruption
events (TDEs) in large numbers, but classifying these generally requires extensive …

Abstract Using the Zwicky Transient Facility, in 2021 February we identified the first known
outburst of the black hole X-ray transient XTE J1859+ 226 since its discovery in 1999. The …

We present upgraded infrastructure for Searches After Gravitational waves Using ARizona
Observatories (SAGUARO) during LIGO, Virgo, and KAGRA's fourth gravitational-wave (GW) …

ABSTRACT GRB 230812B is a bright and relatively nearby (z= 0.36) long gamma-ray burst
(GRB) that has generated significant interest in the community and has thus been observed …

Aims. We present a campaign designed to train the Global Rapid Advanced Network
Devoted to the Multi-messenger Addicts (GRANDMA) network and its infrastructure to follow …
