Optical spectroscopy of the VHE flat-spectrum radio quasar PKS 0903-57

E. Kasai, P. Goldoni, C. Boisson +5

We report new optical spectroscopic results for the gamma-ray blazar PKS~090357. The optical properties of this source have historically been complicated to establish, due to a…

A Multiwavelength Study of a Long-Duration VHE Flare from BL Lacertae with VERITAS

Atreya Acharyya, Avery Archer, Priyadarshini Bangale +72

We report the first observations of a long-duration very-high-energy (VHE; GeV) flare from BL Lacertae (VER J2202+422), taken with the Very Energetic Radiation Imaging Te…

Investigating Active Galactic Nuclei variability with the Cherenkov Telescope Array Observatory

G. Grolleron, J. Biteau, M. Cerruti +21

Blazars, a type of active galactic nuclei (AGN) with relativistic jets pointed at the observer, exhibit flux variability across the electromagnetic spectrum due to particle acceler…

Compelling Evidence for a Harmonic in the Light Curve of the Supermassive Black Hole Binary Candidate PKS J1309+1154

A. C. S. Readhead, M. F. Aller, A. G. Sullivan +23

We recently discovered a supermassive black hole binary (SMBHB) candidate, PKS J1309+1154, in the combined 46-yr University of Michigan Radio Astronomy Observatory (UMRAO) plus Owe…

A Search for Supermassive Black Hole Binary Candidates in 46-Year Radio Light Curves of 83 Blazars

B. Molina, P. Mróz, P. V. De la Parra +23

The combined University of Michigan Radio Astronomy Observatory (UMRAO) and Owens Valley Radio Observatory (OVRO) blazar monitoring programs at 14.5/15 GHz provide uninterrupted li…

Optical spectroscopy of blazars for the Cherenkov Telescope Array Observatory- IV

B. Rajput, P. Goldoni, W. Max-Moerbeck +17

Blazars, including BL Lacs and FSRQs, are the most luminous extragalactic γ-ray sources. They account for about 56% of the sources listed in the recent Fermi-LAT catalog (4FGL-DR4)…
