Searches for Neutrinos in the Direction of Radio-bright Blazars with the ANTARES Telescope

open access: yesThe Astrophysical Journal
Active galaxies, especially blazars, are among the most promising extragalactic candidates for high-energy neutrino sources. To date, ANTARES searches included these objects and used GeV–TeV γ -ray flux to select blazars.

Hunting for Candidates of Changing-look Blazars Using Mclust Clustering Analysis

open access: yesThe Astrophysical Journal
C​​hanging-look blazars (CLBs) are blazars whose optical spectral lines at different epochs show significant changes and present a clear transition between standard FSRQ and BL Lacertae (BL Lac).
