Probing the Metallicity Dependence of Fast Radio Burst Progenitors with CHIME/FRB Outrigger Dwarf Host Galaxies
Y. Dong, W. Fong, K. Nimmo +24
Using the fast radio bursts (FRBs) localized with the CHIME/FRB Outriggers between February and October 2025, we conduct a systematic search for dwarf host galaxies. We identify an…
Cyclotron lines in subcritical X-ray pulsars: Monte Carlo simulations reveal the origin of the observed variability
Prodromos Fotiadis, Nick Loudas, Nikolaos D. Kylafis +1
Observed cyclotron resonant scattering features (CRSFs) in X-ray pulsars (XRPs) exhibit strong variability. In the subcritical luminosity regime, the centroid energy () a…
Unveiling the origin of fast radio bursts by modeling the stellar mass and star formation distributions of their host galaxies
Nick Loudas, Dongzi Li, Michael A. Strauss +1
Diverse formation channels have been proposed to explain the emergence of fast radio bursts (FRBs), yet their origin remains elusive. With improved localization precision, roughly…
A quantitative explanation of the cyclotron-line variation in accreting magnetic neutron stars of super-critical luminosity
Nick Loudas, Nikolaos D. Kylafis, Joachim E. Trümper
Magnetic neutron stars (NSs) often exhibit a cyclotron resonant scattering feature (CRSF) in their X-ray spectra. Cyclotron lines are believed to form in the radiative shock in the…
Cyclotron line formation in the radiative shock of an accreting magnetized neutron star
Nick Loudas, Nikolaos D. Kylafis, Joachim E. Trümper
Magnetic neutron stars (NSs) often exhibit a cyclotron resonant scattering feature (CRSF) in their X-ray spectra, but the site of the CRSF formation is still an open puzzle. A prom…
Cyclotron line formation by reflection on the surface of a magnetic neutron star
N. D. Kylafis, J. E. Trümper, N. A. Loudas
Accretion onto magnetic neutron stars results in X-ray spectra that often exhibit a cyclotron resonance scattering feature (CRSF) and, sometimes, higher harmonics of it. Two places…
Relativistic quantum-mechanical versus classical magnetic resonant scattering cross sections
N. A. Loudas, N. D. Kylafis, J. E. Trümper
Radiative transfer calculations in strong (few G) magnetic fields, observed in X-ray pulsars, require accurate resonant differential scattering cross sections. Suc…
