Probing cosmic strings by reconstructing polarization rotation of the cosmic microwave background
Weichen Winston Yin, Liang Dai, Simone Ferraro
Cosmic birefringence -- the rotation of the polarization of the cosmic microwave background (CMB) photons as they travel to the Earth -- is a smoking gun for axion-like particles (…
Mode-by-mode Relative Binning: Fast Likelihood Estimation for Gravitational Waveforms with Spin-Orbit Precession and Multiple Harmonics
Nathaniel Leslie, Liang Dai, Geraint Pratten
Faster likelihood evaluation enhances the efficiency of gravitational wave signal analysis. We present Mode-by-mode Relative Binning (MRB), a new method designed for obtaining fast…
Mapping the Likelihood of GW190521 with Diverse Mass and Spin Priors
Seth Olsen, Javier Roulet, Horng Sheng Chia +4
We map the likelihood of GW190521, the heaviest detected binary black hole (BBH) merger, by sampling under different mass and spin priors designed to be uninformative. We find that…
Distribution of Effective Spins and Masses of Binary Black Holes from the LIGO and Virgo O1-O3a Observing Runs
Javier Roulet, Horng Sheng Chia, Seth Olsen +4
The distribution of effective spin , a parameter that encodes the degree of spin-orbit alignment in a binary system, has been widely regarded as a robust discriminator…
Signs of Higher Multipoles and Orbital Precession in GW151226
Horng Sheng Chia, Seth Olsen, Javier Roulet +4
We present a reanalysis of GW151226, the second binary black hole merger discovered by the LIGO--Virgo Collaboration. Previous analysis showed that the best-fit waveform for this e…
New Approximation of Magnification Statistics for Random Microlensing of Magnified Sources
Liang Dai, Massimo Pascale
Gravitationally lensed extragalactic sources are often subject to statistical microlensing by stars in the galaxy or cluster lens. Accurate models of the flux statistics are requir…
