Uncovering a population of gravitational lens galaxies with magnified standard candle SN Zwicky
Ariel Goobar, Joel Johansson, Steve Schulze +35
Detecting gravitationally lensed supernovae is among the biggest challenges in astronomy. It involves a combination of two very rare phenomena: catching the transient signal of a s…
Extragalactic Science with the Experiment for Cryogenic Large-aperture Intensity Mapping
Anthony R. Pullen, Patrick C. Breysse, Trevor Oxholm +14
The EXperiment for Cryogenic Large-Aperture Intensity Mapping (EXCLAIM) is a balloon-borne cryogenic telescope that will survey the spectrum of diffuse emission from both the Milky…
The merging galaxy cluster A520 --- a broken-up cool core, a dark subcluster, and an X-ray channel
Qian Wang, Maxim Markevitch, Simona Giacintucci
We present results from a deep Chandra X-ray observation of a merging galaxy cluster A520. A high-resolution gas temperature map, after the subtraction of the cluster-scale emissio…
A Dark Energy Camera Search for an Optical Counterpart to the First Advanced LIGO Gravitational Wave Event GW150914
M. Soares-Santos, R. Kessler, E. Berger +112
We report initial results of a deep search for an optical counterpart to the gravitational wave event GW150914, the first trigger from the Advanced LIGO gravitational wave detector…
Deja Vu All Over Again: The Reappearance of Supernova Refsdal
P. L. Kelly, S. A. Rodney, T. Treu +21
In Hubble Space Telescope (HST) imaging taken on 10 November 2014, four images of supernova (SN) "Refsdal" (redshift z=1.49) appeared in an Einstein-cross--like configuration (imag…
Rapidly Rising Transients in the Supernova - Superluminous Supernova Gap
Iair Arcavi, William M. Wolf, D. Andrew Howell +26
We present observations of four rapidly rising (t_{rise}~10d) transients with peak luminosities between those of supernovae (SNe) and superluminous SNe (M_{peak}~-20) - one discove…
