Tidal disruption event Calorimetry: Observational constraints on the physics of TDE optical flares
Andrew Mummery, Brian Metzger, Sjoert van Velzen +1
Tidal disruption events are routinely discovered as bright optical/UV flares, the properties of which are now well categorized on the population level. The underlying physical proc…
Using Infrared Dust Echoes to Identify Bright Quasi-periodic Eruption Sources
Dheeraj R. Pasham, Eric Coughlin, Sjoert van Velzen +1
Quasi-periodic eruptions (QPEs) are recurring soft X-ray outbursts from galactic nuclei and represent an intriguing new class of transients. Currently, 10 QPE sources are reported…
The optical, UV-plateau and X-ray tidal disruption event luminosity functions reproduced from first principles
Andrew Mummery, Sjoert van Velzen
We reproduce the luminosity functions of the early-time peak optical luminosity, the late-time UV plateau luminosity, and the peak X-ray luminosity of tidal disruption events, usin…
Detectability of a spatial correlation between stellar-mass black hole mergers and Active Galactic Nuclei in the Local Universe
Niccolò Veronesi, Elena Maria Rossi, Sjoert van Velzen +1
The origin of the Binary Black Hole (BBH) mergers detected through Gravitational Waves (GWs) by the LIGO-Virgo-KAGRA (LVK) collaboration remains debated. One fundamental reason is…
The Final Season Reimagined: 30 Tidal Disruption Events from the ZTF-I Survey
Erica Hammerstein, Sjoert van Velzen, Suvi Gezari +30
Tidal disruption events (TDEs) offer a unique way to study dormant black holes. While the number of observed TDEs has grown thanks to the emergence of wide-field surveys in the pas…
AT 2019avd: A novel addition to the diverse population of nuclear transients
A. Malyali, A. Rau, A. Merloni +29
We report on SRG/eROSITA, ZTF, ASAS-SN, Las Cumbres, NEOWISE-R, and Swift XRT/UVOT observations of the unique ongoing event AT 2019avd, located in the nucleus of a previously inact…
