The Phenomenological Nature of Quasar-type Blazars (BZQ). I. Revisiting the Flat-Spectrum Paradigm
Jonhatan U. Guerrero-González, Vahram Chavushyan, Víctor M. Patiño-Álvarez
We reevaluate 610 sources classified as Flat-spectrum radio quasars (FSRQs) in the 5th edition of the Roma-BZCAT. Optical spectra from SDSS DR16 confirm broad emission lines within…
Relationship between the ray variability and the pc-scale jet in the blazar 3C 454.3
Eva Palafox, Víctor Manuel Patiño-Álvarez, Vahram Chavushyan +3
3C 454.3 is a flat spectrum radio quasar (FSRQ) known for its high variability across the electromagnetic spectrum, showing structural and flux variability in its pc-scale jet, and…
Swift-XRT follow-up analysis of unidentified hard X-ray sources
M. Kosiba, F. Massaro, A. Paggi +5
It is currently established that the sources contributing to the cosmic X-ray background (CXB) emission are mainly nearby active galactic nuclei (AGN), in particular those that are…
NOEMA spatially resolved view of the multi-phase outflow in IRAS17020+4544: a shocked wind in action?
Anna Lia Longinotti, Quentin Salomé, Chiara Feruglio +10
The Narrow Line Seyfert 1 Galaxy IRAS17020+4544 is one of the few AGN where a galaxy-scale energy-conserving outflow was revealed. This paper reports on NOEMA observations addresse…
Optical spectroscopic observations of low-energy counterparts of Fermi-LAT gamma-ray sources
H. A. Peña-Herazo, R. A. Amaya-Almazán, F. Massaro +15
A significant fraction of all -ray sources detected by the Large Area Telescope aboard the \fer\ satellite is still lacking a low-energy counterpart. In addition, there is still…
Is there a non-stationary γ-ray emission zone 42 pc away from the 3C 279 core?
Víctor M. Patiño-Álvarez, Sergio A. Dzib, Andrei Lobanov +1
We investigate the relationship between the variable gamma-ray emission and jet properties in the blazar 3C 279, by combining the Fermi/LAT data spanning a period of eight years wi…
