Progenitor models for the" luminous" subclass of Fast Blue Optical Transients (LFBOTs;
prototype: AT2018cow) are challenged to simultaneously explain all of their observed …

The deaths of massive stars are sometimes accompanied by the launch of highly relativistic
and collimated jets. If the jet is pointed towards Earth, we observe a 'prompt'gamma-ray burst …

We present the discovery and extensive follow-up of a remarkable fast-evolving optical
transient, AT 2022aedm, detected by the Asteroid Terrestrial impact Last Alert Survey …

We present AT2020mrf (SRGe J154754. 2+ 443907), an extra-galactic (z= 0.1353) fast blue
optical transient (FBOT) with a rise time of tg, rise= 3.7 days and a peak luminosity of M g …

Several types of energetic supernovae, such as superluminous supernovae (SLSNe) and
broad-line Ic supernovae (Ic-BL SNe), could be powered by the spin-down of a rapidly …

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 …

We present a search for extragalactic fast blue optical transients (FBOTs) during Phase I of
the Zwicky Transient Facility (ZTF). We identify 38 candidates with durations above half …

Observations of the extragalactic (z= 0.0141) transient AT 2018cow established a new class
of energetic explosions shocking a dense medium, producing luminous emission at …

The nature of the newly discovered fast blue optical transients (FBOTs) is still puzzling
astronomers. In this paper, we carry out a comprehensive analysis of the molecular gas …

ABSTRACT AT 2022cmc is a luminous optical transient (νL ν≳ 1045 erg s− 1) accompanied
by decaying non-thermal X-rays (peak duration t X≲ days and isotropic energy EX, iso≳ …
