After the Fall: Late-Time Spectroscopy of Type IIP Supernovae
Jeffrey M. Silverman, Stephanie Pickett, J. Craig Wheeler +11
Herein we analyse late-time (post-plateau; 103 < t < 1229 d) optical spectra of low-redshift (z < 0.016), hydrogen-rich Type IIP supernovae (SNe IIP). Our newly constructed sample…
Optical and ultraviolet spectroscopic analysis of SN 2011fe at late times
Brian Friesen, E. Baron, Jerod T. Parrent +16
We present optical spectra of the nearby Type Ia supernova SN 2011fe at 100, 205, 311, 349, and 578 days post-maximum light, as well as an ultraviolet spectrum obtained with Hubble…
PTF11iqb: Cool supergiant mass loss that bridges the gap between Type IIn and normal supernovae
Nathan Smith, Jon C. Mauerhan, S. Bradley Cenko +16
PTF11iqb was initially classified as a TypeIIn event caught very early after explosion. It showed narrow Wolf-Rayet (WR) spectral features on day 2, but the narrow emission weakene…
The hydrogen-poor superluminous supernova iPTF13ajg and its host galaxy in absorption and emission
Paul M. Vreeswijk, Sandra Savaglio, Avishay Gal-Yam +24
We present imaging and spectroscopy of a hydrogen-poor superluminous supernova (SLSN) discovered by the intermediate Palomar Transient Factory: iPTF13ajg. At a redshift of z=0.7403…
On the Nature of Type Ia-CSM Supernovae: Optical and Near-Infrared Spectra of SN 2012ca and SN 2013dn
Ori D. Fox, Jeffrey M. Silverman, Alexei V. Filippenko +17
A growing subset of Type Ia supernovae (SNe Ia) show evidence for unexpected interaction with a dense circumstellar medium (SNe Ia-CSM). The precise nature of the progenitor, howev…
Twins for life? A comparative analysis of the Type Ia supernovae 2011fe and 2011by
Melissa L. Graham, Ryan J. Foley, Weikang Zheng +6
The nearby Type Ia supernovae (SNe Ia) 2011fe and 2011by had nearly identical photospheric phase optical spectra, light-curve widths, and photometric colours, but at peak brightnes…
