Bright, months-long stellar outbursts announce the explosion of interaction-powered supernovae
Nora L. Strotjohann, Eran O. Ofek, Avishay Gal-Yam +53
Interaction-powered supernovae (SNe) explode within an optically-thick circumstellar medium (CSM) that could be ejected during eruptive events. To identify and characterize such pr…
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…
Optical follow-up of the neutron star-black hole mergers S200105ae and S200115j
Shreya Anand, Michael W. Coughlin, Mansi M. Kasliwal +46
LIGO and Virgo's third observing run (O3) revealed the first neutron star-black hole (NSBH) merger candidates in gravitational waves. These events are predicted to synthesize r-pro…
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…
Constraining the Kilonova Rate with Zwicky Transient Facility Searches Independent of Gravitational Wave and Short Gamma-ray Burst Triggers
Igor Andreoni, Erik C. Kool, Ana Sagues Carracedo +34
The first binary neutron star merger, GW170817, was accompanied by a radioactivity-powered optical/infrared transient called a kilonova. To date, no compelling kilonova has been fo…
Kilonova Luminosity Function Constraints based on Zwicky Transient Facility Searches for 13 Neutron Star Mergers
Mansi M. Kasliwal, Shreya Anand, Tomas Ahumada +100
We present a systematic search for optical counterparts to 13 gravitational wave (GW) triggers involving at least one neutron star during LIGO/Virgo's third observing run. We searc…
