Blazars are active galactic nuclei that direct their particle jets toward Earth. These are extragalactic radio, optical, X-ray, and gamma-ray sources. Cosmic rays accelerated in AGN may interact with surrounding gas or radiation, producing high-energy neutrinos. The IceCube experiment has detected the first extragalactic neutrinos. Goal: to study these sources in detail.
Radio Astronomical Study of Blazar Neutrino Source Candidates Based on Archival VLBA Measurements
We use decades of VLBI radio imaging data from the MOJAVE project. The aim is to map jet structures and study temporal changes in blazars that are candidate neutrino sources.
Gamma-ray Astronomical Study of Blazar Neutrino Source Candidates Based on Fermi Archival Data
Analysis of light curves and maximum likelihood methods using the LAT detector of the Fermi space telescope. The aim is to examine the time variability of one or more gamma-ray emitting neutrino source candidates.
