SN 2011ht: Confirming a Class of Interacting Supernovae with Plateau Light Curves (Type IIn-P)
Jon C. Mauerhan, Nathan Smith, Jeffrey M. Silverman +6
We present photometry and spectroscopy of the Type IIn supernova (SN) 2011ht, identified previously as a SN impostor. The light curve exhibits an abrupt transition from a well-defi…
Evidence for Dust Destruction from the Early-time Colour Change of GRB 120119A
Adam N. Morgan, D. A. Perley, S. B. Cenko +16
We present broadband observations and analysis of Swift gamma-ray burst (GRB) 120119A. Our early-time afterglow detections began under 15 s after the burst in the host frame (redsh…
The properties of the 2175AA extinction feature discovered in GRB afterglows
Tayyaba Zafar, Darach Watson, Ardis Eliasdottir +10
The unequivocal, spectroscopic detection of the 2175 bump in extinction curves outside the Local Group is rare. To date, the properties of the bump have been examined in only two G…
A relativistic jetted outburst from a massive black hole fed by a tidally disrupted star
Joshua S. Bloom, Dimitrios Giannios, Brian D. Metzger +19
While gas accretion onto some massive black holes (MBHs) at the centers of galaxies actively powers luminous emission, the vast majority of MBHs are considered dormant. Occasionall…
Discovery of a Cosmological, Relativistic Outburst via its Rapidly Fading Optical Emission
S. Bradley Cenko, S. R. Kulkarni, Assaf Horesh +26
We report the discovery by the Palomar Transient Factory (PTF) of the transient source PTF11agg, which is distinguished by three primary characteristics: (1) bright, rapidly fading…
Rapid, Machine-Learned Resource Allocation: Application to High-redshift GRB Follow-up
Adam N. Morgan, James Long, Joseph W. Richards +3
As the number of observed Gamma-Ray Bursts (GRBs) continues to grow, follow-up resources need to be used more efficiently in order to maximize science output from limited telescope…
