The TELPERION Survey for Distant [O III] Clouds around Luminous and Hibernating AGN
William C. Keel, Alexei Moiseev, D. V. Kozlova +5
We present a narrowband [O III] imaging survey of 111 AGN hosts and 17 merging-galaxy systems, in search of distant extended emission-line regions (EELRs) around AGN (either extant…
Star formation in the nearby dwarf galaxy DDO 53: interplay between gas accretion and stellar feedback
Oleg V. Egorov, Tatiana A. Lozinskaya, Konstantin I. Vasiliev +4
We present the results of a multiwavelength study of the nearby dwarf galaxy DDO 53 - a relatively isolated member of the M 81 group. We analyse the atomic and ionised gas kinemati…
Scanning Fabry--Perot Interferometer of the 6-m SAO RAS Telescope
A. V. Moiseev
The scanning Fabry-Perot interferometer (FPI) - is the oldest method of optical 3D spectroscopy. It is still in use because of the high spectral resolution it provides over a large…
Observation of a very massive galaxy cluster at z=0.76 in SRG/eROSITA all-sky survey
R. A. Burenin, I. F. Bikmaev, M. R. Gilfanov +16
The results of multiwavelength observations of the very massive galaxy cluster SRGe CL2305.2-2248 detected in X-rays during the first SRG/eROSITA all-sky survey are discussed. This…
Photometry and Long-Slit Spectroscopy of Split Comet C/2019 Y4 (ATLAS)
Oleksandra Ivanova, Igor Luk'yanyk, Dušan Tomko +1
We present an analysis of the photometric and spectroscopic observations of the split comet C/2019 Y4 (ATLAS). Observations were carried out on the 14th and 16th of April 2020 when…
PV Cep and V350 Cep: stars on the way between FUors AND EXors
H. R. Andreasyan, T. Yu. Magakian, T. A. Movsessian +1
Based on new observations during 2015-2020 and published data, the unusual eruptive variables PV Cep and V350 Cep are examined. It is shown that PV Cep underwent a regular outburst…
