MUSE Reveals a Recent Merger in the Post-starburst Host Galaxy of the TDE ASASSN-14li
J. L. Prieto, T. Krühler, J. P. Anderson +13
We present MUSE integral field spectroscopic observations of the host galaxy (PGC 043234) of one of the closest (, Mpc) and best-studied tidal disruption eve…
The Long Term Evolution of ASASSN-14li
J. S. Brown, T. W. -S Holoien, K. Auchettl +5
We present late-time optical spectroscopy taken with the Large Binocular Telescope's Multi-Object Double Spectrograph, late-time SWIFT UVOT and XRT observations, as well as improve…
DM Ori: A Young Star Occulted by a Disturbance in its Protoplanetary Disk
Joseph E. Rodriguez, Keivan G. Stassun, Phillip Cargile +15
In some planet formation theories, protoplanets grow gravitationally within a young star's protoplanetary disk, a signature of which may be a localized disturbance in the disk's ra…
Hello Darkness My Old Friend: The Fading of the Nearby TDE ASASSN-14ae
Jonathan S. Brown, Benjamin J. Shappee, T. W. -S Holoien +3
We present late-time optical spectroscopy taken with the Large Binocular Telescope's Multi-Object Double Spectrograph, an improved ASAS-SN pre-discovery non-detection, and late-tim…
Type II supernovae as probes of environment metallicity: observations of host HII regions
J. P. Anderson, C. P. Gutierrez, L. Dessart +10
Spectral modelling of SNII atmospheres indicates a clear dependence of metal line strengths on progenitor metallicity. This motivates further work to evaluate the accuracy with whi…
ASASSN-15oi: A Rapidly Evolving, Luminous Tidal Disruption Event at 216 Mpc
T. W. -S. Holoien, C. S. Kochanek, J. L. Prieto +17
We present ground-based and Swift photometric and spectroscopic observations of the tidal disruption event (TDE) ASASSN-15oi, discovered at the center of 2MASX J20390918-3045201 ($…
