Photometric Calibrations for 21st Century Science
Stephen Kent, Mary Elizabeth Kaiser, Susana E. Deustua +33
The answers to fundamental science questions in astrophysics, ranging from the history of the expansion of the universe to the sizes of nearby stars, hinge on our ability to make p…
Supernova Photometric Classification Challenge
Richard Kessler, Alex Conley, Saurabh Jha +1
We have publicly released a blinded mix of simulated SNe, with types (Ia, Ib, Ic, II) selected in proportion to their expected rate. The simulation is realized in the griz filters…
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…
Towards a Cosmological Hubble Diagram for Type II-P Supernovae
Peter Nugent, Mark Sullivan, Richard Ellis +13
We present the first high-redshift Hubble diagram for Type II-P supernovae (SNe II-P) based upon five events at redshift up to z~0.3. This diagram was constructed using photometry…
Predicted and observed evolution in the mean properties of Type Ia supernovae with redshift
D. Andrew Howell, Mark Sullivan, Alex Conley +1
Recent studies indicate that Type Ia supernovae (SNe Ia) consist of two groups - a "prompt" component whose rates are proportional to the host galaxy star formation rate, whose mem…
The Peculiar Velocities of Local Type Ia Supernovae and their Impact on Cosmology
James D. Neill, Michael J. Hudson, Alex Conley
We quantify the effect of supernova Type Ia peculiar velocities on the derivation of cosmological parameters. The published distant and local Ia SNe used for the Supernova Legacy S…
Supernova Shock Breakout from a Red Supergiant
Kevin Schawinski, Stephen Justham, Christian Wolf +21
Massive stars undergo a violent death when the supply of nuclear fuel in their cores is exhausted, resulting in a catastrophic "core-collapse" supernova. Such events are usually on…
Results from the Supernova Photometric Classification Challenge
Richard Kessler, Bruce Bassett, Pavel Belov +24
We report results from the Supernova Photometric Classification Challenge (SNPCC), a publicly released mix of simulated supernovae (SNe), with types (Ia, Ibc, and II) selected in p…
The co-evolution of black hole growth and star formation from a cross-correlation analysis between quasars and the cosmic infrared background
Lingyu Wang, Marco Viero, Nicholas P. Ross +19
We present the first cross-correlation measurement between Sloan Digital Sky Survey (SDSS) Type 1 quasars and the cosmic infrared background (CIB) measured by Herschel. The distrib…
The Local Hosts of Type Ia Supernovae
James D. Neill, Mark Sullivan, D. Andy Howell +18
We use multi-wavelength, matched aperture, integrated photometry from GALEX, SDSS and the RC3 to estimate the physical properties of 166 nearby galaxies hosting 168 well-observed T…
