Cosmic evolution and metal aversion in super-luminous supernova host galaxies
S. Schulze, T. Krühler, G. Leloudas +21
The SUperluminous Supernova Host galaxIES (SUSHIES) survey aims to provide strong new constraints on the progenitors of superluminous supernovae (SLSNe) by understanding the relati…
Velocity Segregation and Systematic Biases In Velocity Dispersion Estimates With the SPT-GMOS Spectroscopic Survey
Matthew. B. Bayliss, Kyle Zengo, Jonathan Ruel +15
The velocity distribution of galaxies in clusters is not universal; rather, galaxies are segregated according to their spectral type and relative luminosity. We examine the velocit…
Constraints on the Progenitor of SN 2016gkg From Its Shock-Cooling Light Curve
Iair Arcavi, Griffin Hosseinzadeh, Peter J. Brown +17
SN 2016gkg is a nearby Type IIb supernova discovered shortly after explosion. Like several other Type IIb events with early-time data, SN 2016gkg displays a double-peaked light cur…
The stellar mass - size relation for cluster galaxies at z=1 with high angular resolution from the Gemini/GeMS multi-conjugate adaptive optics system
Sarah M. Sweet, Robert Sharp, Karl Glazebrook +7
We present the stellar mass - size relation for 49 galaxies within the = 1.067 cluster SPT-CL J05465345, with FWHM 80-120 mas -band data from the Gemini…
A search for an optical counterpart to the gravitational wave event GW151226
S. J. Smartt, K. C. Chambers, K. W. Smith +37
We present a search for an electromagnetic counterpart of the gravitational wave source GW151226. Using the Pan-STARRS1 telescope we mapped out 290 square degrees in the optical i_…
Galaxy Populations in Massive Galaxy Clusters to z=1.1: Color Distribution, Concentration, Halo Occupation Number and Red Sequence Fraction
C. Hennig, J. J. Mohr, A. Zenteno +70
We study the galaxy populations in 74 Sunyaev Zeldovich Effect (SZE) selected clusters from the South Pole Telescope (SPT) survey that have been imaged in the science verification…
