AT2023vto: An Exceptionally Luminous Helium Tidal Disruption Event from a Massive Star

Harsh Kumar, Edo Berger, Daichi Hiramatsu +10

We present optical/UV observations and the spectroscopic classification of the transient AT2023vto as a tidal disruption event (TDE) at z = 0.4846. The spectrum is dominated by a b…

A Volume-Limited Radio Search for Magnetic Activity in 140 Exoplanets with the Very Large Array

Kevin N. Ortiz Ceballos, Yvette Cendes, Edo Berger +1

We present results from a search for radio emission in 77 stellar systems hosting 140 exoplanets, predominantly within 17.5 pc using the Very Large Array (VLA) at GHz. This i…

The Peculiar Radio Evolution of the Tidal Disruption Event ASASSN-19bt

Collin T. Christy, Kate D. Alexander, Yvette Cendes +15

We present detailed radio observations of the tidal disruption event (TDE) ASASSN-19bt/AT2019ahk, obtained with the Australia Telescope Compact Array (ATCA), the Atacama Large Mill…

No X-Rays or Radio from the Nearest Black Holes and Implications for Future Searches

Antonio C. Rodriguez, Yvette Cendes, Kareem El-Badry +1

Astrometry from the Gaia mission was recently used to discover the two nearest known stellar-mass black holes (BHs), Gaia BH1 and Gaia BH2. Both systems contain

JWST Observations of the Extraordinary GRB 221009A Reveal an Ordinary Supernova Without Signs of -Process Enrichment in a Low-Metallicity Galaxy

Peter K. Blanchard, V. Ashley Villar, Ryan Chornock +18

Identifying the astrophysical sites of the -process, one of the primary mechanisms by which heavy elements are formed, is a key goal of modern astrophysics. The discovery of the…

A radio-emitting outflow produced by the tidal disruption event AT2020vwl

A. J. Goodwin, K. D. Alexander, J. C. A. Miller-Jones +12

A tidal disruption event (TDE) occurs when a star is destroyed by a supermassive black hole. Broadband radio spectral observations of TDEs trace the emission from any outflows or j…
