Nebular Spectra of 111 Type Ia Supernovae Disfavor Single Degenerate Progenitors
M. A. Tucker, B. J. Shappee, P. J. Vallely +15
We place statistical constraints on Type Ia supernova (SN Ia) progenitors using 227 nebular phase spectra of 111 SNe Ia. We find no evidence of stripped companion emission in any o…
Multidimensional Models of Type Ia Supernova Nebular Spectra: Strong Emission Lines from Stripped Companion Gas Rule Out Classic Single Degenerate Systems
Janos Botyanszki, Daniel Kasen, Tomasz Plewa
The classic single-degenerate model for the progenitors of Type Ia Supernova (SN Ia) predicts that the supernova ejecta should be enriched with solar-like abundance material stripp…
PTF10ops - a subluminous, normal-width lightcurve Type Ia supernova in the middle of nowhere
Kate Maguire, Mark Sullivan, Rollin C. Thomas +26
PTF10ops is a Type Ia supernova (SN Ia), whose lightcurve and spectral properties place it outside the current SN Ia subtype classifications. Its spectra display the characteristic…
The Hubble Space Telescope Cluster Supernova Survey: V. Improving the Dark Energy Constraints Above z>1 and Building an Early-Type-Hosted Supernova Sample
N. Suzuki, D. Rubin, C. Lidman +62
We present ACS, NICMOS, and Keck AO-assisted photometry of 20 Type Ia supernovae SNe Ia from the HST Cluster Supernova Survey. The SNe Ia were discovered over the redshift interval…
Broad-Line Reverberation in the Kepler-Field Seyfert Galaxy Zw 229-015
A. J. Barth, M. L. Nguyen, M. A. Malkan +45
The Seyfert 1 galaxy Zw 229-015 is among the brightest active galaxies being monitored by the Kepler mission. In order to determine the black hole mass in Zw 229-015 from H-beta re…
