Direct analysis of type Ia supernovae spectra.
(2000)
This work describes how to use and modify the highly parameterized spectrum synthesis code (SYNNEW). SYNNEW can be used to derive information directly from type Ia supernovae spectra.
Understanding Type Ia Supernova Diversity with PHOENIX
(2022)
Type Ia Supernovae (SNe Ia) are important astrophysical objects. They produce
roughly half of the iron group elements found in the universe, the energy they
release drives the evolution of galaxies, and their high ...
Synthetic spectrum methods for three dimensional supernova models.
(2003)
This dissertation describes some problems associated with synthesizing emergent spectra from three-dimensional supernova envelope models. We confront these problems by developing a three-dimensional implementation of a ...
On the gravitational lensing of type Ia supernovae.
(2006)
In this dissertation we concentrate on some of these effects on the observation of type Ia supernovae.
Radiative transfer and type Ia supernovae spectra analysis in the context of supernovae factory.
(2005)
We showed the spectrum formation in SNeIa around maximum light to be a multi-layered process involving regions from 5000 km per s to 20000 km per s, interacting not only through scattering but also through pure emission. ...
Various Topics in Type Ia Supernovae
(2019-05-11)
This work takes two approaches to increasing our understanding of type Ia supernovae. The first part uses observations to study their spectral evolution and diversity. The second part uses modeling to investigate a potential ...
Evolution and Stability of Ultra-Wide Trans-Neptunian Binaries
(2023-08-04)
This research is focused around the longevity and formation of a class of binaries in the Kuiper Belt called Ultra-Wide Trans-Neptunian Binaries (Ultra-Wide TNBs). The presence of these seemingly fragile binary systems ...
Probing the large-scale structure of the universe :
(The University of Oklahoma., 1985)
This dissertation presents the discription of 55 bright, close (z (LESSTHEQ) 0.1) clusters of galaxies as a homogeneous sample taken from a new effort to catalogue galaxy clusters in the Southern Hemisphere. The positions ...
BARYON CONTENT TO THE OUTSKIRTS OF LOW-TEMPERATURE POOR GALAXY GROUPS
(2019-12-05)
Little is known concerning the overall properties of galaxy groups, especially at large radii. A better understanding of them will constrain numerical simulations regarding their formation and evolution, as well as reveal ...
