Reverberation in tidal disruption events: dust echoes, coronal emission lines, multi-wavelength cross-correlations, and QPOs
S van Velzen, DR Pasham, S Komossa, L Yan… - Space Science …, 2021 - Springer
Stellar tidal disruption events (TDEs) are typically discovered by transient emission due to
accretion or shocks of the stellar debris. Yet this luminous flare can be reprocessed by gas …

Dynamical unification of tidal disruption events
The∼ 100 tidal disruption events (TDEs) observed so far exhibit a wide range of emission
properties both at peak and over their lifetimes. Some TDEs radiate predominantly at X-ray …

Late-time HST UV and optical observations of AT 2018cow: extracting a cow from its background
The bright, blue, rapidly evolving AT 2018cow is a well-studied peculiar extragalactic
transient. Despite an abundance of multiwavelength data, there still is no consensus on the …
