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.
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.
The direct analysis of spectra of type Ia supernovae.
(2000)
By using SYNOW, we show that most of the spectroscopic differences among type Ia supernovae can be explained by the temperature; therefore, the composition of most of the type Ia supernovae is essentially the same. In ...
A radio and x-ray search for intermediate-age supernovae: Tuning into the oldies.
(2001)
Type II supernovae (SNe) are the cataclysmic and very luminous last stage in the evolutionary track of very high mass stars, resulting in the destruction of the star and the ejection of large amounts of material into their ...
Absolute-magnitude distributions and light curves of stripped-envelope supernovae.
(2004)
The absolute visual magnitudes of three Type IIb, 10 Type Ib and 13 Type Ic supernovae (collectively known as stripped-envelope supernovae) are studied by collecting data on the apparent magnitude, distance, and interstellar ...
Non-local thermodynamic equilibrium spectrum synthesis of type Ia supernovae.
(1997)
This thesis is broken down into 4 major sections, each highlighting a different way with which to use spectrum synthesis to analyze SNe Ia. Chapters 2 and 3 look at normal SNe Ia and their potential use as distance indicators ...
The Sobolev approximation in a spherical shell expanding with constant radial velocity.
(2000)
A simple model of line radiative transfer in a circumstellar shell surrounding a supernova is presented. An examination of optical depth in an atmosphere with power-law expansion and a single source of opacity highlights ...
Determining the distance of SN 1987A with SEAM.
(2001)
Supernovae count among the most luminous phenomena in the universe, and as such they have been sought after to serve as cosmological distance indicators. Type Ia supernovae are currently the most commonly used indicators. ...
"'Tis something, nothing", a search for radio supernovae.
(1998)
We report VLA radio observations of 29 SNe with ages ranging from 10 days to about 90 years past explosion. Included are detections of known radio SNe 1950B, 1957D, 1970G, 1983N, the suspected radio SN 1923A, and the ...
