Type Ia Supernova Spectral Features in the Context of Their Host Galaxy Properties
We analyse spectroscopic measurements of 122 type Ia supernovae (SNe Ia) with z < 0.09 discovered by the Palomar Transient Factory, focusing on the properties of the Si iiλ6355 and Ca ii ‘near-infrared triplet’ absorptions. We examine the velocities of the photospheric Si iiλ6355, and the velocities and strengths of the photospheric and high-velocity Ca ii, in the context of the stellar mass (M...
متن کاملThe Type Ia Supernova
We present the rst measurement of the rate of Type Ia super-novae at high redshift. The result is derived using a large subset of data from the Supernova Cosmology Project as described in more detail at this meeting by Perlmutter et al. (1996). We present our methods for estimating the numbers of galaxies and the number of solar luminosities to which the survey is sensitive, the supernova detec...
متن کاملThe Type Ia Supernova Rate
We explore the idea that the Type Ia supernovae (SNe Ia) rate is made up of two components: a prompt piece that is proportional to the star formation rate (SFR) and an extended piece that is proportional to the total stellar mass. We fit the parameters of this model to the local observations of Mannucci and collaborators and then study its impact on three important problems. On cosmic scales, t...
متن کاملCosmological Inference from Host-Selected Type Ia Supernova Samples
We compare two Type Ia supernova (SN Ia) samples that are drawn from a spectroscopically confirmed SN Ia sample: a host-selected sample in which SNe Ia are restricted to those that have a spectroscopic redshift from the host; and a broader, more traditional sample in which the redshift could come from either the SN or the host. The host-selected sample is representative of SN samples that will ...
متن کاملAre the Models for Type Ia Supernova Progenitors Consistent with the Properties of Supernova Remnants?
We explore the relationship between the models for progenitor systems of Type Ia supernovae and the properties of the supernova remnants that evolve after the explosion. Most models for Type Ia progenitors in the single degenerate scenario predict substantial outflows during the presupernova evolution. Expanding on previous work, we estimate the imprint of these outflows on the structure of the...
