Candidate Tidal Disruption Event AT2019fdr Coincident with a High-Energy Neutrino

Reusch, Simeon ,et.al.; Paliya, Vaidehi S. (Physical Review Letters, 2022-06)

The origins of the high-energy cosmic neutrino flux remain largely unknown. Recently, one high-energy neutrino was associated with a tidal disruption event (TDE). Here we present AT2019fdr, an exceptionally luminous TDE ...
The central engines of Fermi blazars

Paliya, Vaidehi S.; Domínguez, A.; Ajello, M.; Olmo-García, A.; Hartmann, D. (IOP Publishing, 2021-04)

We present a catalog of central engine properties, i.e., black hole mass (MBH) and accretion luminosity (Ldisk), for a sample of 1077 blazars detected with the Fermi Large Area Telescope. This includes broad emission-line ...
Multi-wavelength characterization of Fermi blazars of uncertain type

Paliya, Vaidehi S. (Journal of Astrphysics and Astronomy, 2022-06)

One of the major challenges in the research of jetted active galactic nuclei (AGN) is the completeness of the source catalogs released using the c-ray data taken from the Fermi-large area telescope (LAT). There are about ...
