We present a study of the radio and optical properties of the high-frequency peaker (HFP) blazar PKS 1614+051 at based on the data covering the time period of 1997-2024. T…
High-redshift quasars at : radio variability and MPS/GPS candidates
Yu. Sotnikova, A. Mikhailov, T. Mufakharov +7
We present a study of the radio variability of bright, mJy, high-redshift quasars at on timescales up to 30-40 years. The study involved simultaneous RATA…
Magnetically Driven Relativistic Jet in the High-Redshift Blazar OH~471
S. Guo, T. An, Y. Liu +15
Context : Understanding the mechanisms that launch and shape powerful relativistic jets from supermassive black holes (SMBHs) in high-redshift active galactic nuclei (AGN) is cruci…
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…
GMRT observations of OHM candidates from the ALFALFA survey
Shouzhi Wang, Zhongzu Wu, Bo Zhang +5
We present the results of our observations using the Giant Meterwave Radio Telescope (GMRT) to investigate the radio continuum and OH line emission of 10 OHM candidates from the Ar…
VLBI observations of the high-redshift X-ray bright blazar SRGE J170245.3+130104
Yuanqi Liu, Tao An, Shaoguang Guo +8
Aims. The X-ray luminous and radio-loud AGN SRGE J170245.3+130104 discovered at z 5.5 provides unique chances to probe the SMBH growth and evolution with powerful jets in th…
Radio properties of high-redshift galaxies at
M. Khabibullina, A. Mikhailov, Yu. Sotnikova +6
Study of high-redshift radio galaxies (HzRGs) can shed light on the active galactic nuclei (AGNs) evolution in massive elliptical galaxies. The vast majority of observed high-redsh…
Radio continuum and OH line emission of high-z OH megamaser galaxies
Zhongzu Wu, Yu. V. Sotnikova, Bo Zhang +8
We present the study of arcsecond scale radio continuum and OH line emission of a sample of known OH megamaser galaxies with 0.15 using archival Very Large Array (VLA) dat…
Radio Variability and Broad-Band Spectra of Infrared Galaxies with and without OH Megamaser Emission
Yu. V. Sotnikova, T. V. Mufakharov, A. G. Mikhailov +7
We study the radio variability of galaxies with and without sources of hydroxyl (OH) megamaser radiation based on the continuum radio measurements conducted in 2019-2022 with the r…
Radio properties of the OH megamaser galaxy IIZw 096
Hong Wu, Zhongzu Wu, Yu. Sotnikova +9
Based on the two epochs EVN archive data from OH line observations of IIZw 096, we confirm that the high-resolution OH emission in this source mainly comes from two spots (OH1 and…
Radio continuum properties of OH megamaser galaxies
Yu. V. Sotnikova, Z. Z. Wu, T. V. Mufakharov +13
We present a study of the radio continuum properties of two luminous/ultraluminous infrared galaxy samples: the OH megamaser (OHM) sample (74 objects) and the control sample (128 o…
