Quasi-periodic X-ray eruptions years after a nearby tidal disruption event
M. Nicholl, D. R. Pasham, A. Mummery +61
Quasi-periodic Eruptions (QPEs) are luminous bursts of soft X-rays from the nuclei of galaxies, repeating on timescales of hours to weeks. The mechanism behind these rare systems i…
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…
Eight Years of Light from ASASSN-15oi: Towards Understanding the Late-time Evolution of TDEs
A. Hajela, K. D. Alexander, R. Margutti +26
We present the results from an extensive follow-up campaign of the Tidal Disruption Event (TDE) ASASSN-15oi spanning d, offering an unprecedented window into th…
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…
Late-time X-ray Observations of the Jetted Tidal Disruption Event AT2022cmc: The Relativistic Jet Shuts Off
T. Eftekhari, A. Tchekhovskoy, K. D. Alexander +9
The tidal disruption event (TDE) AT2022cmc represents the fourth known example of a relativistic jet produced by the tidal disruption of a stray star providing a unique probe of th…
