Tidal disruption event rates across cosmic time: forecasts for LSST, Roman, and JWST and their constraints on the supermassive black hole mass function
Mitchell Karmen, Suvi Gezari, Colin Norman +1
The paper builds a semi‑empirical model for how tidal disruption event (TDE) rates evolve with redshift under different supermassive black hole mass‑function scenarios, and uses fo…
Even a precessing clock is right twice per orbit -- The super-periods of eRO-QPE2 and challenges for quasi-periodic eruption orbital models
R. Arcodia, G. Miniutti, J. Chakraborty +25
We present OC (``observed minus calculated'') timing analysis of the quasi-periodic eruption (QPE) source eRO-QPE2 with a multi-mission X-ray campaign, which includes 32 observe…
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…
Demographics of Wandering Black Holes Powering Off-Nuclear Tidal Disruption Events
Muryel Guolo
The recent discovery of three off-nuclear tidal disruption events (EP240222a, AT2024tvd, and AT2025abcr) - following the first such source, 3XMM J215005 - reveals a small but ro…
The Wandering Supermassive Black Hole Powering the off-nuclear TDE AT2024tvd
M. Guolo, A. Mummery, S. van Velzen +11
We present an analysis of the spectral energy distribution (SED) of the off-nuclear tidal disruption event (TDE) AT2024tvd during its late-time plateau phase, combining X-ray spect…
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…
