Hidden shock powering the peak of SN 2020faa
I. Salmaso, E. Cappellaro, L. Tartaglia +9
The link between the fate of the most massive stars and the resulting supernova (SN) explosion is still a matter of debate, in major part because of the ambiguity among light-curve…
The optical light curve of GRB 221009A: the afterglow and the emerging supernova
M. D. Fulton, S. J. Smartt, L. Rhodes +46
We present extensive optical photometry of the afterglow of GRB~221009A. Our data cover \,days from the time of \textit{Swift} and \textit{Fermi} GRB detections. Photom…
Early Lightcurves of Type Ia Supernovae are Consistent with Nondegenerate Progenitor Companions
J. Burke, D. A. Howell, D. J. Sand +16
If Type Ia supernovae (SNe~Ia) result from a white dwarf being ignited by Roche lobe overflow from a nondegenerate companion, then as the supernova explosion runs into the companio…
SN2020qlb: A hydrogen-poor superluminous supernova with well-characterized light curve undulations
S. L. West, R. Lunnan, C. M. B. Omand +21
SN\,2020qlb (ZTF20abobpcb) is a hydrogen-poor superluminous supernova (SLSN-I) that is among the most luminous (maximum M mag) and that has one of the longest rise t…
An elliptical accretion disk following the tidal disruption event AT 2020zso
T. Wevers, M. Nicholl, M. Guolo +25
[Abridged] We classify AT 2020zso as a TDE based on the blackbody evolution inferred from UV/optical photometric observations, and spectral line content and evolution. We identify…
A Systematic Exploration of Kilonova Candidates from Neutron Star Mergers During the Third Gravitational Wave Observing Run
J. Rastinejad, K. Paterson, W. Fong +9
We present a comprehensive analysis of 653 optical candidate counterparts reported during the third gravitational wave (GW) observing run. Our sample concentrates on candidates fro…
Three Core-Collapse Supernovae with Nebular Hydrogen Emission
J. Sollerman, S. Yang, S. Schulze +25
We present SN 2020jfo, a Type IIP supernova in the nearby galaxy M61. Optical light curves from the Zwicky Transient Facility, complemented with data from Swift and near-IR photome…
A low-energy explosion yields the underluminous Type IIP SN 2020cxd
S. Yang, J. Sollerman, N. L. Strotjohann +12
We present observations and analysis of SN 2020cxd, a Low luminous (LL), long-lived Type IIP SN. This object was a clear outlier in the magnitude-limited SN sample recently present…
Searches after Gravitational Waves Using ARizona Observatories (SAGUARO): Observations and Analysis from Advanced LIGO/Virgo's Third Observing Run
K. Paterson, M. J. Lundquist, J. C. Rastinejad +34
With the conclusion of the third observing run for Advanced LIGO/Virgo (O3), we present a detailed analysis of both triggered and serendipitous observations of 17 gravitational wav…
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…
Search for the optical counterpart of the GW170814 gravitationalwave event with the VLT Survey Telescope
A. Grado, E. Cappellaro, S. Covino +30
We report on the search for the optical counterpart of the gravitational event GW170814, which was carried out with the VLT Survey Telescope (VST) by the GRAvitational Wave Inaf Te…
GRAWITA: VLT Survey Telescope observations of the gravitational wave sources GW150914 and GW151226
E. Brocato, M. Branchesi, E. Cappellaro +49
We report the results of deep optical follow-up surveys of the first two gravitational-wave sources, GW150914 and GW151226, done by the GRAvitational Wave Inaf TeAm Collaboration (…
