Multiwavelength variability of the blazar AO 0235+164
V. V. Vlasyuk, Yu. V. Sotnikova, A. E. Volvach +28
We present a study of the multiwavelength (MW) variability of the blazar AO 0235+164 based on the radio-to--ray data covering a long time period from 1997 to 2023. The radio dat…
Cluster analysis of the Roma-BZCAT blazars
D. O. Kudryavtsev, Yu. V. Sotnikova, V. A. Stolyarov +5
Based on the collected multiwavelength data, namely in the radio (NVSS, FIRST, RATAN-600), IR (WISE), optical (Pan-STARRS), UV (GALEX), and X-ray (ROSAT, Swift-XRT) ranges, we have…
Extreme photometric and polarimetric variability of blazar S4 0954+65 at its maximum optical and -ray brightness levels
C. M. Raiteri, M. Villata, M. I. Carnerero +64
In 2022 the BL Lac object S4 0954+65 underwent a major variability phase, reaching its historical maximum brightness in the optical and -ray bands. We present optical photometri…
Doppler confirmation of TESS planet candidate TOI1408.01: grazing transit and likely eccentric orbit
G. A. Galazutdinov, R. V. Baluev, G. Valyavin +16
We report an independent Doppler confirmation of the TESS planet candidate orbiting an F-type main sequence star TOI-1408 located 140 pc away. We present a set of radial velocities…
Photometric study of open clusters Berkeley 96, Berkeley 97, King 12, NGC 7261, NGC 7296, and NGC 7788
Elena V. Glushkova, Marina V. Zabolotskikh, Sergey E. Koposov +4
The BVRcIc CCD photometry in the fields of six open clusters toward the Perseus spiral arm is presented. These data along with JHKs magnitudes taken from 2MASS catalog, have been u…
Optical observations of type IIP supernova 2004dj: Evidence for the asymmetry of Ni ejecta
N. N. Chugai, S. N. Fabrika, O. N. Sholukhova +3
The photometric and spectroscopic observations of nearby type IIP supernova 2004dj are presented. The Ni mass estimated from the light curve is . This…
