SN 2009bb: a Peculiar Broad-Lined Type Ic Supernova
Giuliano Pignata, Maximilian Stritzinger, Alicia Soderberg +23
Ultraviolet, optical, and near-infrared photometry and optical spectroscopy of the broad-lined Type Ic supernova (SN) 2009bb are presented, following the flux evolution from -10 to…
Young Remnants of Type Ia Supernovae and Their Progenitors: A Study of SNR G1.9+0.3
Sayan Chakraborti, Francesca Childs, Alicia Soderberg
Type Ia supernovae, with their remarkably homogeneous light curves and spectra, have been used as standardizable candles to measure the accelerating expansion of the Universe. Yet,…
High Density Circumstellar Interaction in the Luminous Type IIn SN 2010jl: The first 1100 days
Claes Fransson, Mattias Ergon, Peter J. Challis +16
HST and ground based observations of the Type IIn SN 2010jl are analyzed, including photometry, spectroscopy in the ultraviolet, optical and NIR bands, 26-1128 days after first det…
The Transient Gravitational-Wave Sky
Nils Andersson, John Baker, Kris Belczynski +44
Interferometric detectors will very soon give us an unprecedented view of the gravitational-wave sky, and in particular of the explosive and transient Universe. Now is the time to…
A Missing-Link in the Supernova-GRB Connection: The Case of SN 2012ap
Sayan Chakraborti, Alicia Soderberg, Laura Chomiuk +50
Gamma Ray Bursts (GRBs) are characterized by ultra-relativistic outflows, while supernovae are generally characterized by non-relativistic ejecta. GRB afterglows decelerate rapidly…
Radio Supernovae in the Local Universe
Atish Kamble, Alicia Soderberg, Edo Berger +3
In the last three decades, about 50 radio supernovae have been detected as a result of targeted searches of optically discovered supernovae in the local universe. Despite this rela…
The He-rich core-collapse supernova 2007Y: Observations from X-ray to Radio Wavelengths
Maximilian Stritzinger, Paolo Mazzali, Mark M. Phillips +21
A detailed study spanning approximately a year has been conducted on the Type Ib supernova 2007Y. Imaging was obtained from X-ray to radio wavelengths, and a comprehensive set of m…
Probing Quiescent Massive Black Holes: Insights from Tidal Disruption Events
Suvi Gezari, Linda Strubbe, Joshua S. Bloom +10
Tidal disruption events provide a unique probe of quiescent black holes in the nuclei of distant galaxies. The next generation of synoptic surveys will yield a large sample of flar…
Unsupervised Transient Light Curve Analysis Via Hierarchical Bayesian Inference
Nathan Sanders, Michael Betancourt, Alicia Soderberg
Historically, light curve studies of supernovae (SNe) and other transient classes have focused on individual objects with copious and high signal-to-noise observations. In the nasc…
The Nearby Type Ibn Supernova 2015G: Signatures of Asymmetry and Progenitor Constraints
Isaac Shivvers, WeiKang Zheng, Schuyler D. Van Dyk +24
We present the results of an extensive observational campaign on the nearby Type Ibn SN 2015G, including data from radio through ultraviolet wavelengths. SN 2015G was asymmetric, s…
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,…
A comprehensive study of GRB 070125, a most energetic gamma ray burst
Poonam Chandra, S. Bradley Cenko, Dale Frail +21
We present a comprehensive multiwavelength analysis of the bright, long duration gamma-ray burst GRB 070125, comprised of observations in -ray, X-ray, optical, millimeter and c…
Astro2010 Decadal Survey Whitepaper: Coordinated Science in the Gravitational and Electromagnetic Skies
Joshua S. Bloom, Daniel E. Holz, Scott A. Hughes +37
It is widely expected that the coming decade will witness the first direct detection of gravitational waves (GWs). The ground-based LIGO and Virgo GW observatories are being upgrad…
A Closer Look at the Fluctuations in Brightness of SN 2009ip During Its Late 2012 Eruption
John C. Martin, Franz-Josef Hambsch, Raffaella Margutti +3
The supernova impostor SN 2009ip has re-brightened several times since its initial discovery in August 2009. During its last outburst in late September 2012 it reached a peak brigh…
