The interaction of Type Ia supernovae with their circumstellar medium [PDF]

, 2013
This thesis is focused on the study of a specific class of supernovae, named Type Ia (or thermonuclear) supernovae. In particular, we attempt to gain information about their origin through the study of the interaction of these supernovae with ...

Testing the LSST Difference Image Analysis Pipeline Using Synthetic Source Injection Analysis

The Astrophysical Journal
We evaluate the performance of the Legacy Survey of Space and Time Science Pipelines Difference Image Analysis (DIA) on simulated images. By adding synthetic sources to galaxies on images, we trace the recovery of injected synthetic sources to evaluate ...

Carnegie Supernova Project: Fast-declining Type Ia Supernovae as Cosmological Distance Indicators

The Astrophysical Journal
In this paper, the suitability of fast-declining Type Ia supernovae (SNe Ia) as cosmological standard candles is examined utilizing a “Hubble Flow” sample of 43 of these objects observed by the Carnegie Supernova Project (CSP).

1991T-like Supernovae

The Astrophysical Journal Supplement Series
Understanding the nature of the luminous 1991T-like supernovae (SNe) is of great importance to SN cosmology as they are likely to have been more common in the early Universe.

Late Light Curves of Normally-Luminous Type Ia Supernovae

, 2006
The use of Type Ia supernovae as cosmological tools has reinforced the need to better understand these objects and their light curves. The light curves of Type Ia supernovae are powered by the nuclear decay of 56Ni →56 Co →56 Fe.

Progenitors of Type Ia Supernovae

, 2011
: Type Ia supernovae are important, but mysterious cosmological tools. Their standard brightnesses have enabled cosmologists to measure extreme distances and to discover dark energy.
