Searching for Gravitational Waves from Compact Binary Coalescence Using LIGO and Virgo Data
… the LIGO Scientific Collaboration (LSC) and the Virgo Collaboration. We briefly review the physics of gravitational-wave emission and detection, describing how gravitational waves are emitted from "inspiraling" compact stellar mass objects and how the LSC and Virgo try to detect them using …

The search for unmodeled gravitational-wave transients in the Advanced LIGO-Virgo Era
… and thus their detections with Advanced LIGO-Virgo has led to an enormous number of physical insights. Nevertheless, we expect transient GW sources with waveforms that are not fully modeled or are too quiet to be fully resolved may contain an abundant wealth of physical richness in their own …

Characterization of the Galactic White Dwarf Population in the Next Generation Virgo Cluster Survey
… uses optical data from the Next Generation Virgo Cluster Survey (NGVS) and ultravoilet data from the GALEX Ultraviolet Virgo Cluster Survey (GUViCS) to select candidates which may belong to this population of recently formed halo white dwarfs. A colour selection was used to separate white …

Observing galaxies in the Southern Filament of the Virgo Cluster with KAT-7 and WSRT
… of galaxies in a ~1.5° X 2.5° region of the Virgo cluster using the Karoo Array Telescope (KAT-7) and the Westerbork Synthesis Radio Telescope (WSRT). With a total observing time of ~78 hours with the KAT-7 and 48 hours with the WSRT, we search for low HI column density features in the …

Literature, interarts, and multimodality in the narrative of Seán Virgo: a transmedial inquiry into pictorial, architectural, theatrical, musical, and iconotextual tranfers
… the fictional world of poet and writer Seán Virgo. The transmedial areas explored embrace transliterations from the motley art fields of book illustration, painting, architecture, theatre, and music into fiction. Chapter 1 installs the theoretical setup and assesses the profoundly artistic …

Enhancing the detection and the reconstruction of gravitational-wave transients in the LIGO-Virgo-KAGRA data using weak assumptions on the astrophysical sources
… a gravitational-wave (GW) in 2015, the LIGO and Virgo detectors reported tens of astrophysical signals interpreted as mergers of compact objects. These observations provide invaluable tests of the General Relativity and open a new era of astronomy, unveiling compact objects’ nature. The focus of …

Binary Neutron Star Mergers: Gravitational-wave Measurements of Their Parameters and the Nuclear Equation of State
… Observatory (LIGO) together with the Virgo observatory has detected an additional 51 confirmed signals from binary mergers. Two of these signals, GW170817 and GW190425, were identified as binary neutron star mergers. As detector sensitivity improves we expect to see many more binary …

Eccentricity of Merging Neutron Star Binaries: Searches, Parameter Estimation, and Future Prospects
… Observatory (LIGO) and the Advanced Virgo observatory have detected 48 binary black hole mergers and two binary neutron star mergers. Knowledge about the properties of the binary can be gained from the gravitational-wave observations. Binary neutron star systems can form with …

Open Issues in the search for gravitational wave transients
The LIGO-Virgo network of kilometer-scale laser interferometric gravitational-wave detectors reached a major milestone with the successful operation of LIGO's fifth (S5) and Virgo's first (VSR1) science runs during 2005-2007. This thesis presents several issues related to gravitational-wave …
