Spectroscopic galaxy redshifts in the Peanut cluster -- a massive nearly head-on cluster merger shortly after pericenter passage
I. Zaznobin, N. Lyskova, I. Bikmaev +13
The Peanut cluster (SRGe J023820.8+200556, SRGe CL0238.3+2005, = 0.42) has recently emerged as a candidate for a rare, massive merger, potentially analogous to the Bulle…
Archaeology of Galactic Nuclei Activity
A. V. Moiseev, A. Arshinova, A. A. Smirnova
Considerable observational evidence suggests that the activity of supermassive black holes in galactic nuclei is transient. The term ``active galactic nuclei archaeology'' has even…
Here Be SDRAGNs - Spiral Galaxies Hosting Large Double Radio Sources
Jean Tate, William C. Keel, Michael O'Keeffe +16
We present a sample of large double radio sources hosted by spiral galaxies (Spiral Double Radio Active Galactic Nuclei, SDRAGNs). Candidates were selected during Radio Galaxy Zoo,…
Green Bean galaxies and the fading echoes of AGN activity
A. Arshinova, K. Sanderson, A. Moiseev
Green Bean is a rare type of galaxy which represents a short-lived phase in the life cycle of active galactic nuclei (AGN), characterised by large-scale, powerful ionised clouds in…
Polarization of active galactic nuclei with significant VLBI-Gaia displacements
Dmitry Blinov, Arina Arshinova
Numerous studies have reported significant displacements in the coordinates of active galactic nuclei between measurements using radio interferometry techniques and those obtained…
