Observational Manifestations of Primordial Objects in the Early Universe Through the Hydrogen Subordinate Lines
Viktor K. Dubrovich, Yury N. Eroshenko, Stanislav I. Shirokov
A new mechanism for the formation of spectral--spatial distortions in cosmic microwave background radiation near primordial massive compact objects (such as primordial black holes)…
A broadband outburst of the compact steep-spectrum quasar 3C 138 in 2024-2026
T. V. Mufakharov, Yu. V. Sotnikova, V. V. Vlasyuk +20
After several decades of relative quiescence, the compact steep-spectrum quasar 3C 138 entered an active phase in 2024-2026, exhibiting strong broadband flaring. We investigate its…
New optical velocities for local galaxy candidates
Maksim Chazov, Igor Karachentsev, Serafim Kaisin
We used the 6-meter BTA telescope to determine radial velocities for 46 galaxies, previously considered to be nearby objects. Twelve of them have kinematic distances within 13Mpc a…
Structure of the Stellar Neighborhood of CQ Tau in the Presence of a Companion in an Elongated Orbit
Tatiana Demidova
There are indirect signs of the presence of a companion near the star CQ\,Tau. A period of 10\;years was found in the brightness changes. The image of the disk shows an extensive c…
Long-term speckle interferometric monitoring of binary systems II: 2007-2025 positional measurements and improvement of orbits
Arina Mitrofanova, Vladimir Dyachenko, Anatoly Beskakotov +4
This article is focused on the analysis of observational data and improvement of orbital solutions of 8 objects. The listed objects are members of a sample of approximately 300 nea…
Indicatives of Early Stages of Star Formation in the Universe
Irina Acharova, Margarita Sharina
The paper analyzes formation conditions for globular clusters (GCs) in circumgalactic clouds. The similarity between the metallicity distributions of GCs in the nearby Universe and…
