Spectral Hardening Revealed by Geometric De-boosting in the Masked Jet of PKS 2155304
Alberto Domínguez, Adithiya Dinesh, Elena Madero
Blazar gamma-ray variability is predominantly stochastic and well described by red-noise processes. However, a subset of sources shows quasi-periodic oscillations (QPOs) on year-lo…
A New Measurement of the Extragalactic Background Light using 15\,yr of {\it Fermi}-Large Area Telescope Data
Anuvab Banerjee, Justin D. Finke, Marco Ajello +5
The extragalactic background Light (EBL) from ultraviolet to infrared comprises the emission from all stars, galaxies, and actively accreting black holes in the observable Universe…
Coexistence of Chromatic Flares and an Achromatic QPO in the Gamma-ray Blazar PG 1553+113
Elena Madero, Alberto Domínguez
The physical origin of quasi-periodic oscillations (QPOs) in blazars remains debated, with geometric and plasma-driven scenarios as the main competing interpretations. Discriminati…
Geometric masking in AGN jets and its implications for unification and blazar physics
Alberto Domínguez
I explore the theoretical implications of the Geometric Masking scenario for AGN Unification and the blazar sequence. In PKS 2155304, GeV spectral hardening appears locked to it…
A Catalogue of Variable Active Galactic Nuclei Based on Multi-Timescale Variability Analysis from Fermi-LAT Data
Luana Passos-Reis, Elisabete M. de Gouveia Dal Pino, Tarek Hassan +2
Active Galactic Nuclei (AGN) sources feature supermassive black holes that launch relativistic plasma jets. They are key -ray sources providing a unique laboratory for studying…
Distortions in Periodicity Analysis of Blazars II: The Impact of Gaps
P. Peñil, N. Torres-Albà, A. Rico +4
Time series analysis is fundamental to characterizing the variability inherent in multi-wavelength emissions from blazars. However, a major observational challenge lies in the need…
Extensive Analysis of gamma-Ray Periodicity in Jetted AGN from the 4FGL Catalog Using Fermi-LAT Observations
P. Peñil, A. Domínguez, S. Buson +3
The quest to uncover periodic patterns within the -ray emissions of jetted active galactic nuclei (AGN) has recently emerged as a focal point in astrophysics. One of the primary…
TeV Emission in NGC 4278: Shock Energetics Insufficient, Compact Origin Favored
Alberto Domínguez
The Large High Altitude Air Shower Observatory recently detected TeV emission from the low-luminosity active galactic nucleus (LLAGN) NGC 4278. Integral-field spectroscopy with MEG…
Combined dark matter search towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS
LAT Collaboration, S. Abdollahi, L. Baldini +586
Dwarf spheroidal galaxies (dSphs) are excellent targets for indirect dark matter (DM) searches using gamma-ray telescopes because they are thought to have high DM content and a low…
Discovering High- BL Lacs Using Swift/UVOT and SARA Observations with the Dropout Technique
Y. Sheng, K. Imam, A. Kaur +14
Measuring spectroscopic redshifts for BL Lacertae (BL Lac) objects, a class of blazar, is challenging because their optical spectrum lacks, or has weak, emission lines ( equivalent…
