Variability of Blazars and Blazar Models over 38 Years [PDF]
Galaxies, 2016 Since 1978, when BL Lac objects and violently variable quasars were married to become “blazars”, physical interpretations of the phenomenon have evolved. Remarkably, though, the general picture of relativistic jets beaming their radiation in our direction, proposed that year by Blandford and Rees, remains intact.

Boosted dark matter versus dark matter-induced neutrinos from single and stacked blazars
Journal of High Energy PhysicsThe physics responsible for the production of observed high-energy neutrinos have not been established so far, neither for the diffuse astrophysical ones nor for those detected from single blazars.

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.

, 2003 This review paper discusses the past and present observations of gamma-ray blazars with both space and ground-based gamma-ray telescopes (such as EGRET and current TeV telescopes), and with the VLBA. I also discuss the more sensitive gamma-ray telescopes such as AGILE and GLAST that will become available over the next several years, and how ...

Engineering, 2019 The most common approaches to prevent and treat graft-versus-host disease (GVHD) are intended to deplete or suppress the T cells capable of mediating or supporting alloresponses; however, this renders the recipients functionally T cell deficient and ...

Multi-Band Optical Variability of Blazar 1ES 2344+514 on Diverse Time-Scales
Journal of Advanced Research in Natural and Applied SciencesThis study presents the results of multi-band observations from 2022 to 2024 and Zwicky Transient Facility (ZTF) observations from 2018 to 2023, examining the flux variability of the blazar 1ES 2344+514 on diverse time-scales in the optical bands.

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.
