Comparison of statistical treatments for the equation of state for core-collapse supernovae
(2009) [Journal article]Neutrinos emitted during the collapse, bounce, and subsequent explosion provide information about supernova dynamics. The neutrino spectra are determined by weak interactions with nuclei and nucleons in the inner regions ... -
A dark energy camera search for missing supergiants in the LMC after the advanced LIGO gravitational-wave event GW150914
(2016) [Journal article]The collapse of a stellar core is expected to produce gravitational waves (GWs), neutrinos, and in most cases a luminous supernova. Sometimes, however, the optical event could be significantly less luminous than a supernova ... -
DES13S2cmm : the first superluminous supernova from the Dark Energy Survey
(2015) [Journal article]We present DES13S2cmm, the first spectroscopically-confirmed superluminous supernova (SLSN) from the Dark Energy Survey (DES).We briefly discuss the data and search algorithm used to find this event in the first year of ... -
Discovery of an ultramassive pulsating white dwarf
(2013) [Journal article]We announce the discovery of themostmassive pulsating hydrogen-atmosphere white dwarf (WD) ever discovered, GD 518. Model atmosphere fits to the optical spectrum of this star show it is a 12,030 ± 210 K WD with a log g = ... -
First cosmology results using SNe Ia from the dark energy survey : analysis, systematic uncertainties, and validation
(2019) [Journal article]We present the analysis underpinning the measurement of cosmological parameters from 207 spectroscopically classified SNe Ia from the first 3 years of the Dark Energy Survey Supernova Program (DES-SN), spanning a redshift ... -
OzDES multifibre spectroscopy for the Dark Energy Survey : 3-yr results and first data release
(2017) [Journal article]We present results for the first three years of OzDES, a six year programme to obtain redshifts for objects in the Dark Energy Survey (DES) supernova fields using the 2dF fibre positioner and AAOmega spectrograph on the ... -
SDSS J124043.01+671034.68 : the partially burned remnant of a low-mass white dwarf that underwent thermonuclear ignition?
(2020) [Journal article]The white dwarf SDSS J124043.01+671034.68 (SDSS J1240+6710) was previously found to have an oxygen-dominated atmosphere with significant traces of neon, magnesium, and silicon. A possible origin via a violent late thermal ...
