SN 2014C: VLBI Images of a Supernova Interacting with a Circumstellar Shell
Michael F. Bietenholz, A. Kamble, R. Margutti +2
We report on VLBI measurements of supernova 2014C at several epochs between and 1057 days after the explosion. SN 2014C was an unusual supernova that initially had Type I…
Line Identifications of Type I Supernovae: On the Detection of Si II for these Hydrogen-poor Events
J. T. Parrent, D. Milisavljevic, A. M. Soderberg +1
Here we revisit line identifications of type I supernovae and highlight trace amounts of unburned hydrogen as an important free parameter for the composition of the progenitor. Mos…
Imaging the Expanding Shell of SN 2011dh
A. de Witt, M. F. Bietenholz, A. Kamble +5
We report on third epoch VLBI observations of the radio-bright supernova SN 2011dh located in the nearby (7.8 Mpc) galaxy M51. The observations took place at d after the ex…
Ultra High Energy Cosmic Ray Acceleration in Engine-driven Relativistic Supernovae
Sayan Chakraborti, Alak Ray, Alicia Soderberg +2
The origin of the highest energy cosmic rays remains an enigma. They offer a window to new physics, including tests of physical laws relevant to their propagation and interactions,…
The Host Galaxies of Swift Dark Gamma-Ray Bursts: Observational Constraints on Highly Obscured and Very High-Redshift GRBs
D. A. Perley, S. B. Cenko, J. S. Bloom +13
In this work we present the first results of our imaging campaign at Keck Observatory to identify the host galaxies of "dark" gamma-ray bursts (GRBs), events with no detected optic…
An Intermediate Luminosity Transient in NGC300: The Eruption of a Dust-Enshrouded Massive Star
E. Berger, A. M. Soderberg, R. A. Chevalier +10
[abridged] We present multi-epoch high-resolution optical spectroscopy, UV/radio/X-ray imaging, and archival Hubble and Spitzer observations of an intermediate luminosity optical t…
