SDSS J170745+302056: a low surface brightness galaxy in a group
V. P. Reshetnikov, S. S. Savchenko, A. V. Moiseev +1
On the basis of the SDSS survey and spectral observations with the 6-m telescope of SAO RAS, we have peformed a detailed study of SDSS J170745+302056. By combination of its charact…
Multi-wavelength temporal and spectral variability of the blazar OJ 287 during and after the December 2015 flare: a major accretion disc contribution
P. Kushwaha, A. C. Gupta, P. J. Wiita +33
We present a multi-wavelength spectral and temporal analysis of the blazar OJ 287 during its recent activity between December 2015 -- May 2016, showing strong variability in the ne…
Measuring the X-shaped structures in edge-on galaxies
S. S. Savchenko, N. Ya. Sotnikova, A. V. Mosenkov +2
We present a detailed photometric study of a sample of 22 edge-on galaxies with clearly visible X-shaped structures. We propose a novel method to derive geometrical parameters of t…
Spatial environment of polar-ring galaxies from the SDSS
S. S. Savchenko, V. P. Reshetnikov
Based on SDSS data, we have considered the spatial environment of galaxies with extended polar rings. We used two approaches: estimating the projected distance to the nearest compa…
