Quimby,Avishay Gal-Yam,Bradley Cenko,de Antonius Bruyn,Atish Kamble,Ralph A. M. J. Wijers,Alexander J. van der Horst,Chryssa Kouveliotou,Philipp Podsiadlowski,Mark Sullivan,Kate Maguire,D. Andrew Howell,Peter Nugent,Neil Gehrels,Nicholas M. Law,Dovi Poznanski,Michael M. Shara +24 more
TL;DR: In this article, the authors present the analysis of radio and X-ray observations, yielding the tightest constraints yet placed on the pre-explosion mass-loss rate from the progenitor system of this supernova.
Journal ArticleDOI
Revisiting Optical Tidal Disruption Events with iPTF16axa
Tiara Hung,Suvi Gezari,Nadejda Blagorodnova,Nathaniel Roth,S. B. Cenko,S. B. Cenko,Shrinivas R. Kulkarni,Assaf Horesh,Iair Arcavi,Iair Arcavi,Curtis McCully,Curtis McCully,Lin Yan,Ragnhild Lunnan,Christoffer Fremling,Yi Cao,Yi Cao,Peter Nugent,Peter Nugent,P. Wozniak +19 more
TL;DR: In this paper, the authors reported the discovery by the intermediate Palomar Transient Factory (iPTF) of a candidate TDE iPTF16axa at z = 0.108 and presented its broadband photometric and spectroscopic evolution from three months of follow-up observations with ground-based telescopes and Swift.
Journal ArticleDOI
THE PROGENITOR OF SUPERNOVA 2011dh/PTF11eon IN MESSIER 51
Schuyler D. Van Dyk,Weidong Li,S. Bradley Cenko,Mansi M. Kasliwal,Assaf Horesh,Eran O. Ofek,Adam L. Kraus,Jeffrey M. Silverman,I. Arcavi,Alexei V. Filippenko,Avishay Gal-Yam,Robert M. Quimby,Shrinivas R. Kulkarni,O. Yaron,David Polishook +14 more
TL;DR: In this article, a luminous star was identified at the position of supernova 2011dh/PTF11eon, in pre-SN archival, multi-band images of the nearby, nearly face-on galaxy Messier 51 (M51) obtained by the Hubble Space Telescope with the Advanced Camera for Surveys.

TL;DR: Observations of iPTF14hls are reported, an event that has spectra identical to a hydrogen-rich core-collapse supernova, but characteristics that differ extensively from those of known supernovae.
Journal ArticleDOI
Flash Spectroscopy: Emission Lines from the Ionized Circumstellar Material Around <10-Day-Old Type II Supernovae
