Continuation of an Optical Spectroscopic Campaign of Fermi Blazar Candidates with TNG: Discovery of a New Changing-Look Blazar
N. Álvarez Crespo, A. Domínguez, V. S. Paliya +3
Context. Blazars are a distinct subclass of active galactic nuclei (AGN), known for their fast variability, high polarization, and intense emission across the electromagnetic spect…
Search for Extended GeV Sources in the Inner Galactic Plane
S. Abdollahi, F. Acero, A. Acharyya +108
The recent detection of extended -ray emission around middle-aged pulsars is interpreted as inverse-Compton scattering of ambient photons by electron-positron pairs escaping the…
A Multiwavelength Study of the Most Distant Gamma-ray Detected BL Lacertae Object 4FGL J1219.0+3653 ()
Srijita Hazra, Vaidehi S. Paliya, A. Domínguez +3
BL Lac objects are a class of jetted active galactic nuclei that do not exhibit or have weak emission lines in their optical spectra. Recently, the first -ray emitting BL Lac be…
Radio Morphology of Gamma-ray Sources: Double-Lobed Radio Sources
Vaidehi S. Paliya, D. J. Saikia, Alberto Domínguez +1
The extragalactic gamma-ray sky is dominated by relativistic jets aligned to the observer's line of sight, i.e., blazars. A few of their misaligned counterparts, e.g., radio galaxi…
Decade-long periodicity study of 2FHL blazars with historical optical data
Sagar Adhikari, Pablo Peñil, Alberto Domínguez +3
In our recent investigation, we utilized a century's worth of archival optical data to search for a decade-long periodicity from the blazar PG 1553+113, finding a hint of a 22-yr p…
Influence of Cosmic Voids on the propagation of TeV Gamma Rays and the Puzzle of GRB 221009A
Hassan Abdalla, Soebur Razzaque, Markus Böttcher +2
The recent detection of gamma-ray burst GRB~221009A has attracted attention due to its record brightness and first-ever detection of TeV rays from a GRB. Despite b…
