The GstLAL Search Analysis Methods for Compact Binary Mergers in Advanced LIGO's Second and Advanced Virgo's First Observing Runs
Surabhi Sachdev, Sarah Caudill, Heather Fong +26
After their successful first observing run (September 12, 2015 - January 12, 2016), the Advanced LIGO detectors were upgraded to increase their sensitivity for the second observing…
Testing General Relativity with Present and Future Astrophysical Observations
Emanuele Berti, Enrico Barausse, Vitor Cardoso +50
One century after its formulation, Einstein's general relativity has made remarkable predictions and turned out to be compatible with all experimental tests. Most of these tests pr…
Star Clusters and Dark Matter as Probes of the Spacetime Geometry of Massive Black Holes
Laleh Sadeghian
This thesis includes two main projects. In the first part, we assess the feasibility of a recently suggested strong-field general relativity test, in which future observations of a…
Testing the black hole no-hair theorem at the galactic center: Perturbing effects of stars in the surrounding cluster
Laleh Sadeghian, Clifford M. Will
Observations of the precessing orbits of stars very near the massive black hole in the galactic center could provide measurements of the spin and quadrupole moment of the hole and…
Quantum induced w = -1 crossing of the quintessence and phantom models
M. Alimohammadi, L. Sadeghian
Considering the single scalar field models of dark energy, i.e. the quintessence and phantom models, it is shown that the quantum effects can cause the system crosses the w = -1 li…
