Research Theme: Dynamics of dark matter in intermediate mass-ratio inspirals
This post describes three papers on the dynamics of dark matter in intermediate mass-ratio inspirals (IMRIs), the gravitational waves emitted from these syst...
Research Theme: Extended BMS Algebra, Spin and Center-of-Mass Memory Effects
This post summarizes four papers related to the conserved quantities of an extension of the Bondi-Metzner-Sachs (BMS) group and two related new memory effect...
Research Activity: Athena and LISA White Papers
This post summarizes three white papers to which I contributed, one about the European Space agency (ESA) mission Athena and the other two related to the ES...
Research Theme: Forecasts for detecting the gravitational-wave memory effect with current and future detectors
This post summarizes work on when the gravitational-wave memory effect and spin memory effect will be able to be detected by the Advanced LIGO and Virgo dete...
Research Theme: Persistent Gravitational-Wave Observables
This post summarizes two papers about three new procedures by which one can measure generalized notions of gravitational-wave memory. The first paper was an ...
Research Theme: Brans-Dicke theory in Bondi-Sachs form
This post reviews two papers that treat asymptotically flat spacetimes in Brans-Dicke theory. In the first paper, we gave the conditions for asymptotic flat...
Research Theme: Definitions of (super) angular momentum in asymptotically flat spacetimes
This post highlights a paper and essay that investigates several commonly used definitions of angular momentum and super angular momentum in asymptotically f...
Paper: Constraining the Properties of the Progenitor of GW170817
This post summarizes a paper about how well one can distinguish whether the progenitor of the GW170817 event was a binary neutron star or a neutron-star blac...
Paper: Testing General Relativity Using Golden Black-Hole Binaries
This post describes a paper outlining the methodology for testing general relativity with binary black holes, which was later applied to the LIGO and Virgo d...
Research Theme: Gravitational-Wave Memory and Relativistic Angular Momentum
This post describes three papers related to defining a locally measured angular momentum, comparing this angular momentum measured by different observers, an...
Research Theme: Short-Wavelength Quasinormal Modes
This post describes two papers and a comment about quasinormal modes of Kerr black holes in the short-wavelength (geometric-optics) limit.
Research Theme: Visualizing Spacetime Curvature with Vortex and Tendex Lines
This post is a summary of six papers I wrote with collaborators during my Ph.D. about visualizing spacetime curvature around binary-black-hole mergers.
Research Theme: Hybrid Post-Newtonian and Black-Hole Perturbation Model
This post is a summary of two papers I wrote with Yanbei Chen during my Ph.D. about a semi-analytical model for explaining the properties of the gravitationa...
Research Theme: Black-Hole Recoil Velocity and the Landau-Lifshitz Pseudotensor
This post is a summary of three papers I wrote towards the begining of my Ph.D. about gravitational recoils from merging binary black holes.
