Indirect Probes of Dark Matter and Globular Cluster Properties From Dark Matter Annihilation within the Coolest White Dwarfs
Travis J. Hurst, Andrew R. Zentner, Aravind Natarajan +1
White Dwarfs (WD) capture Dark Matter (DM) as they orbit within their host halos. These captured particles may subsequently annihilate, heating the stellar core and preventing the…
Search for Supermassive Black Hole Binaries in the Sloan Digital Sky Survey Spectroscopic Sample
Wenhua Ju, Jenny E. Greene, Roman R. Rafikov +2
Supermassive black hole (SMBH) binaries are expected in a Lambda CDM cosmology given that most (if not all) massive galaxies contain a massive black hole at their center. So far, h…
Variability of Broad Emission Lines in High-Luminosity,High-Redshift Quasars
Sui Chi Woo, David A. Turnshek, Carles Badenes +1
We examine the variability of the high-ionization Lyman alpha lambda 1216 broad emission line (BEL) in a sample of 61 high-luminosity, high-redshift quasars observed at two epochs…
Addressing Decadal Survey Science through Community Access to Highly Multiplexed Spectroscopy with BigBOSS on the KPNO Mayall Telescope
Caty Pilachowski, Carles Badenes, Stephen Bailey +87
This document summarizes the results of a community-based discussion of the potential science impact of the Mayall+BigBOSS highly multiplexed multi-object spectroscopic capability.…
Is the metallicity of their hosts a good measure of the metallicity of Type Ia supernovae?
Eduardo Bravo, Carles Badenes
The efficient use of Type Ia supernovae (SNIa) for cosmological studies requires knowledge of any parameter that can affect their luminosity in either systematic or statistical way…
Metallicity as a source of dispersion in the SNIa bolometric light curve luminosity-width relationship
E. Bravo, I. Dominguez, C. Badenes +2
The recognition that the metallicity of Type Ia supernova (SNIa) progenitors might bias their use for cosmological applications has led to an increasing interest in its role on the…
