braneworld cosmology and holography [PDF]

, 2002
This thesis is devoted to studying two important aspects of braneworld physics: their cosmology and their holography. We examine the Einstein equations induced on a general (n - 2)-brane of arbitrary tension, embedded in some n-dimensional bulk.

Solution to a problem with general relativity

, 2004
It was proposed that a mechanism of gravity should be developed to rigorously test all of the consequences of the physical fluid model for the fabric of space.

Transition redshift: new kinematic constraints from supernovae

, 2008
The transition redshift (deceleration/acceleration) is discussed by expanding the deceleration parameter to first order around its present value. A detailed study is carried out by considering two different parametrizations, q = q(0) + q(1)z and q = q(0)

Improved Methods for General Relativistic Radiation Hydrodynamics and Their Impact on Simulations of Neutron Star Mergers and Core-Collapse Supernovae

Thesis (Ph.D.)--Michigan State University. Physics - Doctor of Philosophy, 2024Neutron star mergers and core-collapse supernovae are some of the most energetic events in the universe, reaching conditions not attainable in terrestrial laboratories.

Allgemeinrelativistische Mehrdimensionale Simulationen von Electron-Capture-Supernovae

, 2015
Electron capture supernovae are explosions of low-mass, Oxygen-Neon-Magnesium core stars. These complex events have to be studied with the help of numerical simulations.

Gravitational Radiation, Luminous Black Holes and Gamma-Ray Burst Supernovae

, 2005
Black holes and gravitational radiation are two of the most dramatic predictions of general relativity. The quest for rotating black holes - discovered by Roy P.

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 extinction of each event ...
