Optical and near-infrared photometry of 94 type II supernovae from the Carnegie Supernova Project
J. P. Anderson, C. Contreras, M. D. Stritzinger +43
Type II supernovae (SNeII) mark the endpoint in the lives of hydrogen-rich massive stars. Their large explosion energies and luminosities allow us to measure distances, metalliciti…
Origin of the strong sodium absorption of the lensed supernova 2016geu at z=0.4
Christa Gall, Jens Hjorth, Lise Christensen +7
The origin of strong sodium absorption, which has been observed for a few nearby Type Ia supernovae (SNe Ia), remains elusive. Here we analyse two high-signal-to-noise, intermediat…
Optical Spectroscopy of Type Ia Supernovae by the Carnegie Supernova Projects I and II
N. Morrell, M. M. Phillips, G. Folatelli +57
We present the second and final release of optical spectroscopy of Type Ia Supernovae (SNe Ia) obtained during the first and second phases of the Carnegie Supernova Project (CSP-I…
