SN 2019cqc: A Hydrogen-rich Superluminous Supernova Showing Electron-Scattering Signatures
Dinesh Hebbar, Rupak Roy, Matt Nicholl +15
Hydrogen-rich superluminous supernovae without narrow emission lines (SLSNe-II) are rare transients whose powering mechanisms remain debated, particularly the role of circumstellar…
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…
Can tidal disruption event models reliably measure black hole masses?
C. R. Angus, A. J. Smith, D. Magill +15
Tidal disruption event (TDE) light curves are increasingly used to infer the masses of quiescent supermassive black holes (), offering a powerful probe of low-mass bla…
AT2024wpp: An Extremely Luminous Fast Ultraviolet Transient Powered by Accretion onto a Black Hole
Daniel A. Perley, Anna Y. Q. Ho, Zoë McGrath +69
We present the discovery of AT 2024wpp ("Whippet"), a fast and luminous 18cow-like transient. At a redshift of z=0.0868, revealed by Keck Cosmic Web Imager spectroscopy of its fain…
Tidal Disruption Events
Brenna Mockler, Erica Hammerstein, Eric R. Coughlin +1
Stars that orbit too close to a black hole can be ripped apart by strong tides, producing a type of luminous transient event called a ``tidal disruption event" (TDE). Tidal disrupt…
A luminous and hot infrared through X-ray transient at a 5 kpc offset from a dwarf galaxy
Jean J. Somalwar, Vikram Ravi, Raffaella Margutti +20
We are searching for hot, constant-color, offset optical flares in the Zwicky Transient Facility (ZTF) data stream that are from any galaxy in public imaging data from th…
The first systematically identified repeating partial tidal disruption event
Jean J. Somalwar, Vikram Ravi, Yuhan Yao +13
Tidal disruption events (TDEs) occur when a star enters the tidal radius of a supermassive black hole (SMBH). If the star only grazes the tidal radius, a fraction of the stellar ma…
Rubin Observatory's Survey Strategy Performance for Tidal Disruption Events
K. Bučar Bricman, S. van Velzen, M. Nicholl +1
Tidal Disruption Events (TDEs) are rare transients, which are considered as promising tools in probing supermassive black holes in quiescent galaxies. The majority of …
