Energetic eruptions leading to a peculiar hydrogen-rich explosion of a massive star
Iair Arcavi, D. Andrew Howell, Daniel Kasen +50
Every supernova hitherto observed has been considered to be the terminal explosion of a star. Moreover, all supernovae with absorption lines in their spectra show those lines decre…
The Rapid Reddening and Featureless Optical Spectra of the optical counterpart of GW170817, AT 2017gfo, During the First Four Days
Curtis McCully, Daichi Hiramatsu, D. Andrew Howell +17
We present the spectroscopic evolution of AT 2017gfo, the optical counterpart of the first binary neutron star (BNS) merger detected by LIGO and Virgo, GW170817. While models have…
Nebular-Phase Spectra of Nearby Type Ia Supernovae
Melissa L. Graham, Sahana Kumar, Griffin Hosseinzadeh +8
We present late-time spectra of eight Type Ia supernovae (SNe Ia) obtained at days after peak brightness using the Gemini South and Keck telescopes. All of the SNe Ia in our…
Early Observations of the Type Ia Supernova iPTF 16abc: A Case of Interaction with Nearby, Unbound Material and/or Strong Ejecta Mixing
A. A. Miller, Y. Cao, A. L. Piro +19
Early observations of Type Ia supernovae (SNe Ia) provide a unique probe of their progenitor systems and explosion physics. Here we report the intermediate Palomar Transient Factor…
Optical and IR observations of SN 2013L, a Type IIn Supernova surrounded by asymmetric CSM
Jennifer E. Andrews, Nathan Smith, Curtis McCully +3
We present optical and NIR photometry and spectroscopy of SN 2013L for the first four years post-explosion. SN 2013L was a moderately luminous (M = -19.0) Type IIn supernova…
Early Blue Excess from the Type Ia Supernova 2017cbv and Implications for Its Progenitor
Griffin Hosseinzadeh, David J. Sand, Stefano Valenti +11
We present very early, high-cadence photometric observations of the nearby Type Ia SN 2017cbv. The light curve is unique in that it has a blue bump during the first five days of ob…
Clues to the Nature of SN 2009ip II: The Continuing Photometric and Spectroscopic Evolution to 1000 Days
Melissa L. Graham, Andrew Bigley, Jon C. Mauerhan +6
The 2012 brightening of SN 2009ip was dominated by emission from the interaction of ejecta with the surrounding circumstellar material (CSM) produced by episodic mass loss from the…
Confined Dense Circumstellar Material Surrounding a Regular Type II Supernova: The Unique Flash-Spectroscopy Event of SN 2013fs
O. Yaron, D. A. Perley, A. Gal-Yam +30
With the advent of new wide-field, high-cadence optical transient surveys, our understanding of the diversity of core-collapse supernovae has grown tremendously in the last decade.…
Multiwavelength follow-up of a rare IceCube neutrino multiplet
M. G. Aartsen, M. Ackermann, J. Adams +501
On February 17 2016, the IceCube real-time neutrino search identified, for the first time, three muon neutrino candidates arriving within 100 s of one another, consistent with comi…
Growing evidence that SNe Iax are not a one-parameter family: the case of PS1-12bwh
M. R. Magee, R. Kotak, S. A. Sim +10
In this study, we present observations of a type Iax supernova, PS1-12bwh, discovered during the Pan-STARRS1 3-survey. Our analysis was driven by previously unseen pre-maximum,…
