    • Comparison of statistical treatments for the equation of state for core-collapse supernovae 

      Souza, Sergio Ricardo de Azevedo; Steiner, Andrew W.; Lynch, William G.; Donangelo, Raul José; Famiano, Michael A. (2009) [Artículo de periódico]
      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 ...

C.; Tarle, Gregory; Thaler, Jon J.; Thomas, Rollin C.; Tucker, Douglas L.; Vikram, Vinu; Wechsler, Risa H.; Weller, Jochen; Wester, William Carl; DES Collaboration (2016) [Artículo de periódico]
      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 ...

C.; Tarle, Gregory; Thaler, Jon J.; Tucker, Douglas L.; Wechsler, Risa H.; Zuntz, J. (2015) [Artículo de periódico]
      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 

      Hermes, James J.; Kepler, Souza Oliveira; Castanheira, Bárbara Garcia; Gianninas, Alexandros; Winget, Donald Earl; Montgomery, Michael Houston; Brown, Warren R.; Harrold, Samuel T. (2013) [Artículo de periódico]
      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 

      Brout, Dillon J.; Santiago, Basilio Xavier; DES Collaboration (2019) [Artículo de periódico]
      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 

      Childress, Michael; Ostrovski, F.; DES Collaboration (2017) [Artículo de periódico]
      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? 

      Gänsicke, Boris; Koester, Detlev; Raddi, Roberto; Toloza, Odette F.; Kepler, Souza Oliveira (2020) [Artículo de periódico]
      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 ...
