    In this first paper in a series, we present 1298 low-redshift (z ? 0.2) optical spectra of 582 Type Ia supernovae (SNe Ia) observed from 1989 to 2008 as part of the Berkeley Supernova Ia Program (BSNIP). 584 spectra of 199 ...
  • Crepuscular Rays from the Highly Inclined Active Galactic Nucleus in IC 5063 
    Maksym, W. Peter; Schmidt, Judy; Keel, William C.; Fabbiano, Giuseppina; Fischer, Travis C.; Bland-Hawthorn, Joss; Barth, Aaron J.; Elvis, Martin; Oosterloo, Tom; Ho, Luis C.; Kim, Minjin; Hwang, Hyunmo; Mayer, Evan (2020)
    On Earth near sunset, the Sun may cast "crepuscular rays" such that clouds near the horizon obscure the origin of light scattered in bright rays. In principle, active galactic nuclei (AGN) should be able to produce ...
