Multiwavelength Analysis of Six Luminous Fast Blue Optical Transients
Cassie Sevilla, Anna Y. Q. Ho, Nayana A. J. +43
We present multiwavelength observations and analysis of six luminous fast blue optical transients (LFBOTs) discovered in Zwicky Transient Facility (ZTF) survey data. We identified…
The ZTF-ULTRASAT experiment: Characterizing the non-transients in ULTRASAT's high cadence survey
Daniel Warshofsky, Michael W. Coughlin, Theophile Jegou Du Laz +16
The forthcoming launch of the Ultraviolet Transient Astronomy Satellite (ULTRASAT) will transform our understanding of the transient ultraviolet sky by increasing our ability to id…
A Natural Telescope: Discovery of the Strongly Lensed Type II SN 2025mkn at
Cameron Lemon, Ariel Goobar, Joel Johansson +90
We present the discovery of SN 2025mkn, a gravitationally lensed Type II supernova. First detected as a blue transient in ZTF, 0.83 from a elliptical gala…
AT2024lhc and AT2024kmq in the landscape of featureless tidal disruption events
Yuhan Yao, Ryan Chornock, Andrew Mummery +39
We study AT2024kmq and AT2024lhc, two tidal disruption events (TDEs) with blue featureless spectra associated with high-mass black holes (). Both even…
An Extremely Luminous Flare Recorded from a Supermassive Black Hole
Matthew J. Graham, Barry McKernan, K. E. Saavik Ford +17
Since their discovery more than 60 years ago, accreting supermassive black holes in active galactic nuclei (AGN) were recognized as highly variable sources, requiring an extremely…
SN 2023uqf: An Interacting Supernova Coincident with a High-Energy Neutrino
Robert Stein, Anna Y. Q. Ho, Anjasha Gangopadhyay +30
Astrophysical high-energy (TeV-PeV) neutrinos were first discovered in 2013, but their origin remains largely unknown. Here we present SN 2023uqf, a supernova found in coincidence…
