Confirmation of intermediate-mass black holes candidates with X-ray observations
Victoria Toptun, Igor Chilingarian, Kirill Grishin +5
The origin of supermassive black holes (SMBH) in galaxy centers still remains uncertain. There are two possible ways of their formation - from massive () and…
Multi-segment and Echelle stellar spectra processing issues and how to solve them
Sviatoslav Borisov, Igor Chilingarian, Evgenii Rubtsov +7
High-quality stellar spectra are in great demand now - they are the most important ingredient in the stellar population synthesis to study galaxies and star clusters. Here we descr…
A Population of Bona Fide Intermediate Mass Black Holes Identified as Low Luminosity Active Galactic Nuclei
Igor V. Chilingarian, Ivan Yu. Katkov, Ivan Yu. Zolotukhin +4
Nearly every massive galaxy harbors a supermassive black hole (SMBH) in its nucleus. SMBH masses are millions to billions , and they correlate with properties of spheroi…
Two new magnetic cataclysmic variables discovered in the 3XMM catalogue
N. A. Webb, A. Schwope, I. Zolotukhin +2
X-ray catalogues provide a wealth of information on many source types, ranging from compact objects to galaxies, clusters of galaxies, stars, and even planets. Thanks to the huge v…
RCSED - A Value-Added Reference Catalog of Spectral Energy Distributions of 800,299 Galaxies in 11 Ultraviolet, Optical, and Near-Infrared Bands: Morphologies, Colors, Ionized Gas and Stellar Populations Properties
Igor Chilingarian, Ivan Zolotukhin, Ivan Katkov +3
We present RCSED, the value-added Reference Catalog of Spectral Energy Distributions of galaxies, which contains homogenized spectrophotometric data for 800,299 low and intermediat…
The slowest spinning X-ray pulsar in an extragalactic globular cluster
Ivan Zolotukhin, Matteo Bachetti, Nicola Sartore +2
Neutron stars are thought to be born rapidly rotating and then exhibit a phase of a rotation-powered pulsations as they slow down to 1-10 s periods. The significant population of m…
