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 insight into the dark side. I. The pitfalls of the dark halo parameters estimation
Anna Saburova, Anastasia Kasparova, Ivan Katkov
We examined the reliability of estimates of pseudoisothermal, Burkert and NFW dark halo parameters for the methods based on the mass-modelling of the rotation curves.To do it we co…
Stellar counter-rotation in lenticular galaxy NGC 448
Ivan Yu. Katkov, Olga K. Sil'chenko, Igor V. Chilingarian +2
The counter-rotation phenomenon in disc galaxies directly indicates a complex galaxy assembly history which is crucial for our understanding of galaxy physics. Here we present the…
The Diversity of Thick Galactic Discs
Anastasia V. Kasparova, Ivan Yu. Katkov, Igor V. Chilingarian +3
Although thick stellar discs are detected in nearly all edge-on disc galaxies, their formation scenarios still remain a matter of debate. Due to observational difficulties, there i…
