Low mass X-ray binaries (LMXBs) are systems of compact stellar remnants accreting from a low mass companion star. These systems show various levels of mass transfer on various timescales. Many aspects of accretion in these systems are still not fully understood, specifically the emission...

Constraining the Jet Properties of the New Transient X-ray Binary, Swift J1745-26, With the Submillimeter Array and James Clerk Maxwell Telescope
DownloadFall 2014
Accreting astrophysical sources are an important end-result of intricate stellar dynamics. A particularly puzzling aspect of this accretion process is the production and evolution of plasma outflows (known as jets). Although astrophysical jets have been studied for decades in accreting sources,...

Constraining the Physics of the X-ray Irradiated Accretion Discs in Low-mass X-ray Binaries with Observations
DownloadFall 2018
Recurring outbursts associated with matter flowing onto compact stellar remnants (black holes and neutron stars) in low-mass X-ray binary systems provide constraints on the poorly understood accretion process. Multi-wavelength light-curves and spectra of these bright outbursts provide powerful...

Exotic binaries in Galactic globular clusters: identification, classification, and their formation
DownloadFall 2021
Globular clusters (GCs) are dense and massive stellar populations, which provide a unique environment where the high stellar density facilitates frequent dynamical encounters, creating many exotic binaries. These exotic binaries generally have short orbits and often harbour compact objects,...

The Einstein equation with a negative cosmological constant \lambda in the five dimensions for the Randall-Sundrum II model, which includes a black hole, has been solved numerically. We have constructed an AdS5-CFT4 solution numerically, using a spectral method to minimize the integral of the...

The Definitive All-Sky Observational Study Of Accretion Disc Physics In Galactic Black Hole X-ray Binaries
DownloadFall 2014
Stellar mass black holes (BHs) accreting in binary systems provide valuable insight into how binary systems evolve and how mass is transferred via accretion. Although in recent years a canonical picture of the outburst evolution in black hole X-ray binaries (BHXRBs) has emerged, these systems...

We examine the long-term evolution of accretion tori around the remnants of compact object mergers and the explosions of highly magnetized massive stars to better understand their roles in the creation of optical transients and the synthesis of r-process elements. We begin by modifying the...
