Long-term monitoring of Ark 120 with Swift
M. Gliozzi, I. E. Papadakis, D. Grupe +2
We report the results of a six-month Swift monitoring campaign of Ark120, a prototypical bare Seyfert1 galaxy. The lack of intrinsic absorption combined with the nearly contemporan…
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…
The detection and X-ray view of the changing look AGN HE 1136-2304
M. L. Parker, S. Komossa, W. Kollatschny +9
We report the detection of high-amplitude X-ray flaring of the AGN HE 1136-2304, which is accompanied by a strong increase in the flux of the broad Balmer lines, changing its Seyfe…
The Unexpected, Long-Lasting, UV Rebrightening of the Super-Luminous Supernova ASASSN-15lh
D. Godoy-Rivera, K. Z. Stanek, C. S. Kochanek +11
Given its peak luminosity and early-time spectra, ASASSN-15lh was classified as the most luminous supernova (SN) ever discovered (Dong et al. 2016). Here we report a UV rebrighteni…
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 ($…
