Uncovering the physics behind the blazar sequence using a realistic model for jet emission
EPJ Web of Conferences, 2013 Blazar spectra are one of the most important windows into the physical processes occurring along jets. The spectrum, composed from the different emitting regions along the jet, allows us to constrain the physical conditions in the jet.

Recognizing Blazars Using Radio Morphology from the VLA Sky Survey
The Astrophysical JournalBlazars are radio-loud active galactic nuclei whose jets have a very small angle to our line of sight. Observationally, the radio emissions are mostly compact or compact-core with a one-sided jet.

First Results on Long-Term Multiwavelength Variability Analysis in Mrk 421
EPJ Web of Conferences, 2013 Due to the broad-band nature of the emission from blazars, strong efforts are being placed in recent years on simultaneous multiwavelength campaigns as a way to understand the mechanisms responsible for the acceleration of ultra-relativistic particles in

Cosmic Clues from Amaterasu: Blazar-driven Ultrahigh-energy Cosmic Rays?
The Astrophysical Journal LettersThe detection of the Amaterasu event of energy 244 EeV by the Telescope Array, one of the most energetic ultrahigh-energy cosmic rays (UHECRs; E ≳ 0.1 EeV) observed to date, invites scrutiny of its potential source.

Optical Photometric Monitoring of the Blazar OT 355 and Local Standard Stars’ Calibration
UniverseOT 355 (4FGL J1734.3 + 3858) is a relatively rarely studied but highly variable, moderate-redshift (z = 0.975) flat-spectrum radio quasar (blazar). With this work, we aim to study its optical variability on different timescales, which can help us to ...
