Galaxies hosting an AGN: a view from the CALIFA survey
Eduardo A. D. Lacerda, Sebastián F. Sánchez, R. Cid Fernandes +3
We study the presence of optically-selected Active Galactic Nuclei (AGNs) within a sample of 867 galaxies extracted from the extended {\it Calar-Alto Legacy Integral Field spectros…
Initial Evaluation of SNEMO2 and SNEMO7 Standardization Derived From Current Light Curves of Type Ia Supernovae
B. M. Rose, S. Dixon, D. Rubin +7
To determine if the SuperNova Empirical Model (SNEMO) can improve Type Ia supernova (SN Ia) standardization of several currently available photometric data sets, we perform an init…
The Mystery of Photometric Twins DES17X1boj and DES16E2bjy
M. Pursiainen, C. Gutierrez, P. Wiseman +80
We present an analysis of DES17X1boj and DES16E2bjy, two peculiar transients discovered by the Dark Energy Survey (DES). They exhibit nearly identical double-peaked light curves wh…
SN 2016gsd: An unusually luminous and linear type II supernova with high velocities
T. M. Reynolds, M. Fraser, S. Mattila +27
We present observations of the unusually luminous Type II supernova (SN) 2016gsd. With a peak absolute magnitude of V = 19.95 0.08, this object is one of the brightest Typ…
SN2018kzr: a rapidly declining transient from the destruction of a white dwarf
Owen R. McBrien, Stephen J. Smartt, Ting-Wan Chen +31
We present SN2018kzr, the fastest declining supernova-like transient, second only to the kilonova, AT2017gfo. SN2018kzr is characterized by a peak magnitude of , peak…
HSC16aayt: Slowly evolving interacting transient rising for more than 100 days
Takashi J. Moriya, Masaomi Tanaka, Tomoki Morokuma +19
We report our observations of HSC16aayt (SN 2016jiu), which was discovered by the Subaru/Hyper Suprime-Cam (HSC) transient survey conducted as part of Subaru Strategic Program (SSP…
The spectral evolution of AT 2018dyb and the presence of metal lines in tidal disruption events
Giorgos Leloudas, Lixin Dai, Iair Arcavi +29
We present light curves and spectra of the tidal disruption event (TDE) ASASSN-18pg / AT 2018dyb spanning a period of one year. The event shows a plethora of strong emission lines,…
