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…

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 unexpected population of quenched galaxies harbouring under-massive SMBHs revealed by tidal disruption events

Paige Ramsden, Sean L. McGee, Matt Nicholl

Restricted by event horizon suppression, tidal disruption events (TDEs) provide a unique window into otherwise hidden supermassive black holes (SMBHs) at the lower end of the mass…

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…

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…
