Luminous Red Nova AT 2019zhd, a new merger in M 31
A. Pastorello, M. Fraser, G. Valerin +20
We present the follow-up campaign of the luminous red nova (LRN) AT~2019zhd, the third event of this class observed in M 31. The object was followed by several sky surveys for abou…
The First Data Release of CNIa0.02 -- A Complete Nearby (Redshift <0.02) Sample of Type Ia Supernova Light Curves
Ping Chen, Subo Dong, C. S. Kochanek +41
The CNIa0.02 project aims to collect a complete, nearby sample of Type Ia supernovae (SNe Ia) light curves, and the SNe are volume-limited with host-galaxy redshifts z_host < 0.02.…
ASASSN-18am/SN 2018gk : An overluminous Type IIb supernova from a massive progenitor
Subhash Bose, Subo Dong, C. S. Kochanek +29
ASASSN-18am/SN 2018gk is a newly discovered member of the rare group of luminous, hydrogen-rich supernovae (SNe) with a peak absolute magnitude of mag that is in…
A non-equipartition shockwave traveling in a dense circumstellar environment around SN2020oi
Assaf Horesh, Itai Sfaradi, Mattias Ergon +34
We report the discovery and panchromatic followup observations of the young Type Ic supernova, SN2020oi, in M100, a grand design spiral galaxy at a mere distance of Mpc. We fo…
Atacama Compact Array Observations of the Pulsar-Wind Nebula of SNR 0540-69.3
P. Lundqvist, N. Lundqvist, C. Vlahakis +6
We present observations of the pulsar-wind nebula (PWN) region ofSNR 0540-69.3. The observations were made with the Atacama Compact Array (ACA) in Bands 4 and 6. We also add radio…
AT 2017gbl: a dust obscured TDE candidate in a luminous infrared galaxy
E. C. Kool, T. M. Reynolds, S. Mattila +26
We present the discovery with Keck of the extremely infrared (IR) luminous transient AT 2017gbl, coincident with the Northern nucleus of the luminous infrared galaxy (LIRG) IRAS 23…
