Disentagling the optical emission mechanisms in tidal disruption events
P71-019 Koljonen
Summary:
Tidal disruption events (TDEs) are ideal targets to probe the
formation of accretion disks and accompanying
outflows. Multiwavelength observations of TDEs have revealed a
surprisingly diverse population. Especially, the so-called optical
TDEs have shown late-time X-ray and radio emission years after the
optical peak emission indicating delayed accretion disk formation and
long timescales for the circularization process. Therefore, the origin
of the prompt optical emission of these events remains unclear. Here,
we propose imaging polarimetry of tidal disruption events to
understand the location and properties of the optical emission and
subsequently the formation process of the accretion disk around
supermassive black holes. ***

Observations
Our immediate objective is to follow the polarization evolution of optically bright TDEs. Observations should be done in 2-3 weeks cadence (8 in total for one target). For each observation, we require linear polarimetric observations in two different filters (Bessel V and R) using the standard ALFOSC setup. Please, make sure to center the target in the image.
The PI will send the target and observing information using the OB generator when this ToO is triggered (2 triggers/targets in total).
