They illuminate dynamics in galactic nuclei, and may provide constraints on rates of low frequency gravitational wave transients. A handful of candidates have been uncovered, with our recent discovery of a new class of relativistic TDE dramatically adding to the breadth of the population. Here we propose to characterise the spectral and temporal properties of of up to two TDEs found in AO11. As part of a multiwavelength campaign we will use XMM-Newton and HST to track the temperature; search for evidence of non-thermal components and study the long and short timescale variability. In doing so we will create unique panchromatic pictures of these events for the first time. We seek to obtain UV imaging observations of two tidal disruption events. We will utilize F225W or F275W (or both) depending on the properties of the TDE. The aim of the proposal is to i) map the UV emission from the tidal disruption event and ii) precisely position the candidate on its host, relative to the likely locaiton of the black hole. For this latter aim we also ask to be able to use F606W. This provides a much higher signal to noise for ascertaining a centroid and crucially provides a larger number of background objects for relative astrometry between two epochs of observations. Recent improvements in astrometry utilize galaxies to remove the scatter from the proper motions of stars, but we will only have a sufficient number of galaxies for comparison in cases where a redder filter is used. For the UV observations we have placed the source close to the corner of the chip to mitigate CTE. For the optical observations the source is displaced in this direction, but remains closer to the centre of the chip for improved astrometry if latter observations are taken at different roll angles. 12 Regular false false 0.0 0.0 false false false SUPPORTED GALAXY ACCRETION DISK J2000 GALAXY ACCRETION DISK J2000 WFC3/UVIS Imaging No No F225W WFC3/UVIS Imaging No No F275W WFC3/UVIS Imaging No No F225W WFC3/UVIS Imaging No No F275W POS-TARG DITHER 0.135 LINE false false 3 46.84 WFC3-UVIS-DITHER-LINE-3PT 2
