INVESTIGATING [X/FE], IMF AND COMPOSITENESS IN INTEGRATED MODELS
This dissertation explores several existing challenges of evolutionarystellar population synthesis models in integrated light:age-metallicity degeneracy, initial mass function (IMF), elementalabundances, and compositeness. ...
A Study of Globular Cluster Systems in the Shapley Supercluster Region with the Hubble Space Telescope
After a brief introduction to astronomy and topics related to this thesis, we present three projects directed towards expanding our understanding of globular cluster (GC) systems, or populations, in galaxies within clusters.We ...
Neutrinos in Mergers of Neutron Stars with Black Holes
Mergers of a neutron star and a black hole are interesting because of the dual complexity of the black hole's strong gravity and the neutron star's nuclear-density fluid. Mergers can yield short-lived nuclear accretion ...
SEARCHING FOR GRAVITATIONAL-WAVES FROM COMPACT BINARY COALESCENCES WHILE DEALING WITH CHALLENGES OF REAL DATA AND SIMULATED WAVEFORMS
Albert Einstein's general theory of relativity predicts the existence of gravitational waves (GWs). Direct detection of GWs will provide enormous amount of new information about physics, astronomy and cosmology. Scientists ...
A study of convex hull optimization and null-stream-based chi squared discrimination statistics for gravitational-wave signal analysis
We develop data analysis methods to improve the sensitivity of searches for gravitational-wave signals from compact object binaries in networks of ground-based detectors, such as LIGO, Virgo and KAGRA. These are targeted ...
