VHE gamma-ray detection of FSRQ QSO B1420+326 and modeling of its enhanced broadband state in 2020
V. A. Acciari, S. Ansoldi, L. A. Antonelli +230
Context. QSO B1420+326 is a blazar classified as a Flat Spectrum Radio Quasar (FSRQ). In the beginning of 2020 it underwent an enhanced flux state. An extensive multiwavelength cam…
Multi-Wavelength Variability of BL Lacertae Measured with High Time Resolution
Zachary R. Weaver, K. E. Williamson, S. G. Jorstad +54
In an effort to locate the sites of emission at different frequencies and physical processes causing variability in blazar jets, we have obtained high time-resolution observations…
New X-shaped bulge photometric model as a tool for measuring B/PS bulges and their X-structures in photometric studies
Anton A. Smirnov, Sergey S. Savchenko
Recent orbital studies of 3D bar structure in various numerical and analytical models show that X-structures that reside in boxy/peanut-shaped (B/PS) bulges are not delineated by s…
Investigation of the parameters of spiral pattern in galaxies: the arm width
Aleksandr Mosenkov, Sergey Savchenko, Alexander Marchuk
In this work we determine the parameters of spiral structure for a sample of face-on spiral galaxies. In practice, the solution of this problem is a hard task because of the divers…
Quasi-periodic behaviour in the optical and γ-ray light curves of blazars 3C 66A and B2 1633+38
J. Otero-Santos, J. A. Acosta-Pulido, J. Becerra González +18
We report on quasi-periodic variability found in two blazars included in the Steward Observatory Blazar Monitoring data sample: the BL Lac object 3C 66A and the Flat Spectrum Radio…
A multi-wavelength study of spiral structure in galaxies. I. General characteristics in the optical
Sergey Savchenko, Alexander Marchuk, Aleksandr Mosenkov +1
Different spiral generation mechanisms are expected to produce different morphological and kinematic features. In this first paper in a series we carefully study the parameters of…
