A comprehensive power spectral density analysis of astronomical time series. I. The Fermi-LAT gamma-ray light curves of selected blazars
(IOP Publishing, 2020)We present the results of the Fermi-Large Area Telescope 10 yr long light curve (LC) modeling of selected blazars: six flat-spectrum radio quasars (FSRQs) and five BL Lacertae (BL Lacs), examined in 7, 10, and 14 day ... -
The fast radio burst luminosity function and death line in the low-twist Magnetar Model
(IOP, 2020)We explore the burst energy distribution of fast radio bursts (FRBs) in the low-twist magnetar model of Wadiasingh & Timokhin (WT19). Motivated by the power-law fluence distributions of FRB 121102, we propose an elementary ... -
Fast radio burst trains from magnetar oscillations
(IOP Publishing, 2020)Quasi-periodic oscillations inferred during rare magnetar giant flare tails were initially interpreted as torsional oscillations of the neutron star (NS) crust, and have been more recently described as global core+crust ... -
Impact of ordered and disordered magnetic fields on multiwavelength emission of blazars
(IOP Publishing, 2020)We present a detailed analysis of the effects of magnetic field topology on the spectral energy distribution (SED) and spectral variability patterns (SVPs) of blazars. In order to study these effects, we have extended our ... -
Optical observations reveal strong evidence for high-energy neutrino progenitor
(IOP Publishing, 2020)We present the earliest astronomical observation of a high-energy neutrino error box of which the variability was discovered after high-energy-neutrino detection. The one robotic telescope of the MASTER global international ...
