A Wolf–Rayet-like progenitor of SN 2013cu from spectral observations of a stellar wind
Avishay Gal-Yam,Iair Arcavi,Eran O. Ofek,Sagi Ben-Ami,S. B. Cenko,Mansi M. Kasliwal,Yi Cao,O. Yaron,D. Tal,Jeffrey M. Silverman,Assaf Horesh,A. De Cia,Francesco Taddia,Jesper Sollerman,Daniel A. Perley,P. M. Vreeswijk,Shrinivas R. Kulkarni,Peter Nugent,Alexei V. Filippenko,John C Wheeler +19 more
TL;DR: Wolf–Rayet-like wind signatures are identified, suggesting a progenitor of the WN(h) subclass (those WRSs with winds dominated by helium and nitrogen, with traces of hydrogen), consistent with recent theoretical predictions.
Journal ArticleDOI
The outflow structure of GW170817 from late-time broad-band observations
Eleonora Troja,Eleonora Troja,Luigi Piro,Geoffrey Ryan,H. van Eerten,Roberto Ricci,M. H. Wieringa,Simone Lotti,T. Sakamoto,S. B. Cenko +9 more
TL;DR: In this paper, a broad-band study of GW170817 from radio to hard X-rays, including NuSTAR and Chandra observations up to 165 d after the merger, and a multimessenger analysis including LIGO constraints is presented, providing the first detailed comparison between non-trivial cocoon and jet models.

TL;DR: The first plausible optical electromagnetic counterpart to a (candidate) binary black hole merger in the accretion disk of an active galactic nucleus is reported, and a repeat flare in this source due to a reencountering with the disk is predicted.
Journal ArticleDOI
The Host Galaxies of Swift Dark Gamma-ray Bursts: Observational Constraints on Highly Obscured and Very High Redshift GRBs
Daniel A. Perley,S. B. Cenko,Joshua S. Bloom,Hsiao-Wen Chen,Nathaniel R. Butler,Daniel Kocevski,Jason X. Prochaska,Mark Brodwin,Karl Glazebrook,Mansi M. Kasliwal,Shrinivas R. Kulkarni,Sebastian Lopez,Eran O. Ofek,M. Pettini,Alicia M. Soderberg,D. Starr,D. Starr +16 more
TL;DR: In this article, the first results of an imaging campaign at Keck Observatory to identify the host galaxies of "dark" gamma-ray bursts (GRBs), events with no detected optical afterglow or with detected optical flux significantly fainter than expected from the observed X-ray afterglove.
Journal ArticleDOI

TL;DR: In this paper, a large suite of multi-wavelength observations spanning from 300 s to 130 days after a gamma-ray burst (GRB 130427A) was presented, showing that the afterglow shows relatively simple, smooth evolution at all frequencies.
