Title:  The Big 4 of Mathematical Relativity

Abstract:   The big 4 conjectures of mathematical relativity started life as intuitive guesses by a number of physicists. After decades of work, mathematicians have been able to translate these intuitions into precise mathematical questions that are amenable to confirmation by proof or refutation by counterexample. These conjectures remain wide open at present and my aim will be to describe what they're about, how they are inter-related, whether they're...

The puzzle of dark matter halo cores in low- and high redshift galaxies

In the present Universe, especially low-mass galaxies reveal central dark halo properties that

indicate a dark core of constant density and constant velocity dispersion. This is in strong contrast

to cold-dark-matter simulations that predict cuspy, cold cores with a density that diverges towards the center as 1/r,

with a velocity dispersion that decreases towards the center. Several scenarios to explain this discrepancy

are currently being...

Hunting for dark matter in the early Universe

It is now well established that a large part of the matter in the Universe is some substance which appears to be oblivious to any force but gravity. The nature of this dark matter” remains a mystery. Could it be a new particle, as light as an electron, or might it be made of black holes as massive as many Suns? In this talk, I will first describe how one can hope to tease out some of the properties of dark matter from the Cosmic Microwave Background (CMB), the...

Modeling Sub-Chandrasekhar Mass White Dwarf Explosions as Type Ia Supernovae
>
> Abstract:
> Type Ia supernovae are some of the most common cosmic transients, yet their progenitors are still not known. I will discuss my thesis research on a specific pathway to these explosions, known as the double detonation scenario.  I will first describe the hydrodynamic techniques I use to simulate these explosions and to calculate the composition of the outflow.  I will also describe the radiation transport methods I use to translate the hydrodynamical output into synthetic...

Magnetized Models of Moon-Forming Giant Impacts

Abstract: The canonical giant impact hypothesis suggests that ~4.5 billion years ago, a Mars-sized impactor struck the proto-Earth in an off-centered collision. The impact debris, comprised of melted and vaporized silicates, wraps around the proto-Earth forming a Keplerian disk.  From this "protolunar disk”, the Moon is thought to have formed. This talk aims to investigate the role of magnetic fields in a giant impact scenario.  Specifically, I will describe a suite of 3-D numerical MHD simulations that study the...
