The search for the tidal disruption of stars by supermassive black holes (tidal disruption events; TDEs) is now yielding exciting results. Recently, we tied several events together into a coherent class of outbursts. This picture offers a surprising new insight: TDEs show a strong (200x) preference for post-starburst galaxies. Why is this? As likely post-merger galaxies, they could harbor a binary black hole in their center, which is expected to increase the rate of TDEs, but only at certain ages after the merger and for certain merger mass ratios. Alternatively, a disturbed central potential or nuclear gas reservoirs may be affecting stellar orbits in the core of the galaxy. Finally, a nuclear over-abundance of A stars (which dominate ground-based galaxy-integrated spectra), evolving to giants, could increase the global cross section for tidal disruption. HST spatial resolution and low surface brightness sensitivity allows us to test each of these options for four post-starburst TDE host galaxies. We will measure post-merger tidal tails, age-date the starburst using individual star cluster colors, map the luminosity profile of the inner ~100pc to test for asphericity or double nuclei, and localize the weak line emission and A-star population seen in our galaxy-integrated spectra. We will also perform bulge-disk decompositions to estimate the mass of the central black hole, a crucial test of TDE emission models. Our group has successfully carried out HST analyses of the star cluster populations, tidal tails, and core surface brightness profiles of (non-TDE-host) post-starburst galaxies, a sample which will serve as a control for the observations proposed here. We request UVIS imaging and STIS spectroscopy of four post-starburst galaxies. Our galaxies are ~5"-10" in size. Imaging Goals: 1. Measure or set limits on extended tidal tails down to 27 mag/arcsec^2. The tails could extend out to ~25" form the host galaxy center. We therefore use the UVIS2 pointing which puts us ~40" from the nearest chip edge. 2. Measure the color and luminosity of globular clusters for more accurate age-dating of the starburst. For this we require the F438W and F625W filters, and our exposure times are set to achieve a color error of <0.2 mag for clusters brighter than -11 mag at the redshift of our galaxies. We require high spatial resultion in order to detect the globular clusters (the clusters will be unresolved point sources, our need for HST is not to resolve the clusters, but rather for the improved point source sensitivity). 3. Map the luminosity profile of the inner few tens of parsecs to constrain nuclear asphericity and perform disk/bulge decompositions for bulge to black hole mass estimates. We require a limiting surface brightness of 23 mag/arcsec^2 in both F438W and F814W fiters needed to fit the HST data with <10% errors using galfit models. To improve spatial resultion, we implement dithering patterns for all our exposures. We separate our exposures into different visits for each target and filter to imrpove scheduling flexibility (as the different filters do not necesarily have to be obtained consecutively). However, if different visits of the same target can be combined, the time saved for re-acquiring could be used to increase the exposure time on target and improve the signal to noise. Spectroscopy Goals: 1. Perform a spatially resolved characterization of the stellar population as a function of distance from the galactic nucleus for our two brightest targets (ASASSN-14li and ASASSN-14ae). The main spectral lines required for this analysis are those of H (6563, 4861, 4341, 4102, 3970 Ang), Ca H+K (3934, 3969 Ang) and Mg I (3832, 3838, 4571, 5167, 5173 Ang). For this purpose we request to align the slit along the long axis of each of these galaxies (as specified in the orient angles). 2. Localize the weak emission lines in all our targets. Here we wish to use the O I (6300 Ang), Fe X (6437 Ang), N II (6548, 6583 Ang), S II (6716, 6730 Ang) and O III (5007 Ang) lines, in addition to the Balmer sequence (specifically the Hbeta/O III line ratio). We have already detected these lines in ground-based integrated spectra of the hosts but we require HST in order to localize the line emitting region and constrain a likely association to the nucleus. We split each of our spectroscopy exposures in 3 (if an acquisition block is present in the same orbit) or 4 (if acquisition was performed in a previous orbit of the same visit) for cosmic-ray rejection.
