Supernova SN 2020faa -- an iPTF14hls look-alike?
S. Yang, J. Sollerman, T. -W. Chen +14
We present observations of SN 2020faa. This Type II supernova displays a luminous light curve that started to rebrighten from an initial decline. We investigate this in relation to…
Two stripped envelope supernovae with circumstellar interaction -- but only one really shows it
J. Sollerman, C. Fransson, C. Barbarino +23
We present SN 2019tsf (ZTF19ackjszs) and SN 2019oys (ZTF19abucwzt). These two stripped envelope Type Ib supernovae suddenly showed a (re-)brightening in their late light curves. We…
GRB 160625B: Evidence for a Gaussian-Shaped Jet
Virginia Cunningham, S. Bradley Cenko, Geoffrey Ryan +9
We present multiwavelength modeling of the afterglow from the long gamma-ray burst GRB 160625B using Markov Chain Monte Carlo (MCMC) techniques of the afterglowpy Python package. G…
The Palomar Transient Factory Core-Collapse Supernova Host-Galaxy Sample. I. Host-Galaxy Distribution Functions and Environment-Dependence of CCSNe
Steve Schulze, Ofer Yaron, Jesper Sollerman +51
Several thousand core-collapse supernovae (CCSNe) of different flavors have been discovered so far. However, identifying their progenitors has remained an outstanding open question…
SN 2020bqj: a Type Ibn supernova with a long lasting peak plateau
E. C. Kool, E. Karamehmetoglu, J. Sollerman +31
Context: Type Ibn supernovae are a rare class of stripped envelope supernovae interacting with a helium-rich CSM. The majority of the SNe Ibn reported display a surprising homogene…
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…
