AT 2018cow VLBI: No Long-Lived Relativistic Outflow
Michael F. Bietenholz, Raffaella Margutti, Deanne Coppejans +7
We report on VLBI observations of the fast and blue optical transient (FBOT), AT 2018cow. At ~62 Mpc, AT 2018cow is the first relatively nearby FBOT. The nature of AT 2018cow is no…
Discovery and Rapid Follow-up Observations of the Unusual Type II SN 2018ivc in NGC 1068
K. A. Bostroem, S. Valenti, D. J. Sand +44
We present the discovery and high-cadence follow-up observations of SN 2018ivc, an unusual Type II supernova that exploded in NGC 1068 (D=10.1 Mpc). The light curve of SN 2018ivc d…
Supernova Photometric Classification Pipelines Trained on Spectroscopically Classified Supernovae from the Pan-STARRS1 Medium-Deep Survey
V. A. Villar, E. Berger, G. Miller +11
Photometric classification of supernovae (SNe) is imperative as recent and upcoming optical time-domain surveys, such as the Large Synoptic Survey Telescope (LSST), overwhelm the a…
SN 2016coi (ASASSN-16fp): an energetic H-stripped core-collapse supernova from a massive stellar progenitor with large mass loss
G. Terreran, R. Margutti, D. Bersier +25
We present comprehensive observations and analysis of the energetic H-stripped SN 2016coi (a.k.a. ASASSN-16fp), spanning the -ray through optical and radio wavelengths, acquired…
The Type II-Plateau Supernova 2017eaw in NGC 6946 and Its Red Supergiant Progenitor
Schuyler D. Van Dyk, WeiKang Zheng, Justyn R. Maund +31
We present extensive optical photometric and spectroscopic observations, from 4 to 482 days after explosion, of the Type II-plateau (II-P) supernova (SN) 2017eaw in NGC 6946. SN 20…
Astro2020 Science White Paper: Are Supernovae the Dust Producer in the Early Universe?
Jeonghee Rho, Danny Milisavljevic, Arkaprabha Sarangi +23
Whether supernovae are a significant source of dust has been a long-standing debate. The large quantities of dust observed in high-redshift galaxies raise a fundamental question as…
Astro2020 Science White Paper: Discovery Frontiers of Explosive Transients - An ELT & LSST Perspective
Melissa L. Graham, Danny Milisavljevic, Armin Rest +17
The Large Synoptic Survey Telescope (LSST) will open a discovery frontier for faint and fast transients with its ability to detect variable flux components down to 24.5 mag i…
Achieving Transformative Understanding of Extreme Stellar Explosions with ELT-enabled Late-time Spectroscopy
D. Milisavljevic, R. Margutti, R. Chornock +35
Supernovae are among the most powerful and influential explosions in the universe. They are also ideal multi-messenger laboratories to study extreme astrophysics. However, many fun…
On the Ca-strong 1991bg-like type Ia supernova 2016hnk: evidence for a Chandrasekhar-mass explosion
Lluís Galbany, Chris Ashall, Peter Hoeflich +46
We present a comprehensive dataset of optical and near-infrared photometry and spectroscopy of type~Ia supernova (SN) 2016hnk, combined with integral field spectroscopy (IFS) of it…
Two new catalogs of blazar candidates in the WISE infrared sky
Raffaele D'Abrusco, Nuria Alvarez Crespo, Francesco Massaro +9
We present two catalogs of radio-loud candidate blazars whose WISE mid-infrared colors are selected to be consistent with the colors of confirmed gamma-ray emitting blazars. The fi…
Multi-Messenger Astronomy with Extremely Large Telescopes
Ryan Chornock, Philip S. Cowperthwaite, Raffaella Margutti +82
The field of time-domain astrophysics has entered the era of Multi-messenger Astronomy (MMA). One key science goal for the next decade (and beyond) will be to characterize gravitat…
ELT Contributions to Tidal Disruption Events
J. Craig Wheeler, Rafaella Margutti, Ryan Chornock +3
An ELT system with its large aperture and sensitive optical and near infrared imager spectrographs will make major contributions to the study of stars ripped apart by supermassive…
ELT Contributions to The First Explosions
J. Craig Wheeler, József Vinkó, Rafaella Margutti +3
The large aperture and sensitive optical and near infrared imager spectrographs will enable an ELT system to observe some supernovae at large distances, deep into cosmological hist…
