Estimation of neutron star mass and radius of FRB 20240114A by identification of crustal oscillations
Hajime Sotani, Zorawar Wadiasingh, Cecilia Chirenti
By identifying quasi-periodic oscillations (QPOs) reported in FRB 20240114A (from the Five-hundred-meter Aperture Spherical Telescope) with neutron star crustal torsional oscillati…
The Radius of PSR J0437-4715 from NICER Data
M. C. Miller, A. J. Dittmann, I. M. Holt +12
Neutron star Interior Composition Explorer (NICER) data have been used to estimate the masses and radii of the rotation-powered millisecond pulsars PSR J00300451, PSR J074066…
Black hole spectroscopy: from theory to experiment
Emanuele Berti, Vitor Cardoso, Gregorio Carullo +70
The "ringdown" radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of black hole quasinormal modes a…
Tight bound on neutron-star radius with quasiperiodic oscillations in short gamma-ray bursts
Victor Guedes, David Radice, Cecilia Chirenti +1
Quasiperiodic oscillations (QPOs) have been recently discovered in the short gamma-ray bursts (GRBs) 910711 and 931101B. Their frequencies are consistent with those of the quasirad…
Extragalactic Magnetar Giant Flares: Population Implications, Rates and Prospects for Gamma-Rays, Gravitational Waves and Neutrinos
Paz Beniamini, Zorawar Wadiasingh, Aaron Trigg +5
Magnetar Giant Flares (MGFs) are the most energetic non-catastrophic transients known to originate from stellar objects. The first discovered events were nearby. In recent years, s…
