Type Ia Supernova Light Curve Inference: Hierarchical Bayesian Analysis in the near Infrared

We present a comprehensive statistical analysis of the properties of Type Ia SN light curves in the near infrared using recent data from PAIRITEL and the literature. We construct a hierarchical Bayesian framework, incorporating several uncertainties including photometric error, peculiar velocities, dust extinction and intrinsic variations, for principled and coherent statistical inference. SN I...

Type Ia Supernova Light Curves

The diversity of Type Ia supernova (SN Ia) photometry is explored using a grid of 130 one-dimensional models. It is shown that the observable properties of SNe Ia resulting from Chandrasekhar-mass explosions are chiefly determined by their final composition and some measure of “mixing” in the explosion. A grid of final compositions is explored including essentially all combinations of Ni, stabl...

Type Ia Supernova Rates Near and Far

Recently, three important observational results were established: (a) The evolution of the SNIa rate with redshift is now measured up to z∼1.6 and the results at the highest redshifts, derived by the GOODS collaboration show that the SN rate rises up to z∼0.8, when the Universe was 6.5 Gyr old, and decreases afterward. (b) The rate of supernova explosions of the different types as a function of...

PTF10ops – a subluminous, normal-width light curve Type Ia supernova in the middle of nowhere

PTF10ops is a Type Ia supernova (SN Ia), whose light curve and spectral properties place it outside the current SN Ia subtype classifications. Its spectra display the characteristic lines of subluminous SNe Ia, but it has a normal-width light curve with a long rise time, typical of normal-luminosity SNe Ia. The early-time optical spectra of PTF10ops were modelled using a spectral fitting code a...

Analysis of the Type Ia Supernova Sn1994d

On Mar. 7, 1994, Treffers, Filippenko and Van Dyk (1994) discovered the Type Ia supernova (SN Ia) 1994D in the SO galaxy NGC 4526, a member of the Virgo cluster which was was about 12 days before maximum light. Subsequently, both the light curve in Johnson’s UBVRI colors and spectra a have been monitored by several groups (e.g. Filippenko et al. private communication, Smith et al., 1995) making...
