Straightforward mode hierarchy in eccentric binary black hole mergers and associated waveform model
Tousif Islam
Utilizing publicly available non-spinning eccentric binary black hole (BBH) merger simulations (\href{https://data.black-holes.org/waveforms/catalog.html}{https://data.black-holes.…
Mapping between black-hole perturbation theory and numerical relativity II: gravitational-wave momentum
Tousif Islam
We report an approximate, non-trivial mapping of angular (linear) momentum in gravitational waves obtained from numerical relativity (NR) and adiabatic point-particle black hole pe…
Searching for intermediate mass ratio binary black hole mergers in the third observing run of LIGO-Virgo-KAGRA
Mark Ho-Yeuk Cheung, Digvijay Wadekar, Ajit Kumar Mehta +6
Intermediate mass ratio inspirals (IMRIs) of binary black holes with mass ratios are astrophysically interesting sources of gravitational waves. Me…
Including higher-order modes in a quadrupolar eccentric numerical relativity surrogate using universal eccentric modulation functions
Tousif Islam, Adhrit Ravichandran, Peter James Nee +15
\texttt{gwNRHME} is a framework that converts multi-modal (i.e., containing several spherical harmonic modes) quasi-circular waveforms into their eccentric counterparts, provided t…
Enigmatic Velocity Dispersions of Ultra-Diffuse Galaxies in Light of Modified Gravity Theories and Radial Acceleration Relation
Tousif Islam
Recent observations of anomalous line-of-sight velocity dispersions of two ultra-diffuse galaxies (UDGs) provide a stringent test for modified gravity theories. While NGC 1052-DF2…
Globular clusters as a probe for Weyl Conformal Gravity
Tousif Islam
Eventual flattening of velocity dispersion profiles of some galactic globular clusters in the Milky Way cannot be explained in the framework of Newtonian gravity and hence in gener…
