Search for the edge-on galaxies using an artificial neural network
S. S. Savchenko, D. I. Makarov, A. V. Antipova +1
We present an application of an artificial neural network methodology to a modern wide-field sky survey Pan-STARRS1 in order to build a high-quality sample of disk galaxies visible…
The problem of dust attenuation in photometric decomposition of edge-on galaxies and possible solutions
Sergey Savchenko, Denis Poliakov, Aleksandr Mosenkov +6
The presence of dust in spiral galaxies affects the ability of photometric decompositions to retrieve the parameters of their main structural components. For galaxies in an edge-on…
Barless flocculent galaxies: a dynamic puzzle
Daria Zakharova, Natalia Ya. Sotnikova, Anton A. Smirnov +1
We draw attention to the bright galaxies that do not show a bar in their structure but have a flocculent spiral structure. Using the THINGS' and HERACLES' kinematic data for four b…
Discovery of X-ray polarization angle rotation in active galaxy Mrk 421
Laura Di Gesu, Herman L. Marshall, Steven R. Ehlert +140
The magnetic field conditions in astrophysical relativistic jets can be probed by multiwavelength polarimetry, which has been recently extended to X-rays. For example, one can trac…
The optical behaviour of BL Lacertae at its maximum brightness levels: a blend of geometry and energetics
C. M. Raiteri, M. Villata, S. G. Jorstad +13
In 2021 BL Lacertae underwent an extraordinary activity phase, which was intensively followed by the Whole Earth Blazar Telescope (WEBT) Collaboration. We present the WEBT optical…
A Three-Dimensional Analytical Model of the Interstellar Extinction within the Nearest Kiloparsec
G. A. Gontcharov, A. V. Mosenkov, S. S. Savchenko +6
We present a new version of our analytical model of the spatial interstellar extinction variations within the nearest kiloparsec. This model treats the 3D dust distribution as a su…
Prospects for future studies using deep imaging: Analysis of individual Galactic cirrus filaments
Anton A. Smirnov, Sergey S. Savchenko, Denis M. Poliakov +6
The presence of Galactic cirrus is an obstacle for studying both faint objects in our Galaxy and low surface brightness extragalactic structures. With the aim of studying individua…
Interstellar Extinction in Galactic Cirri in SDSS Stripe 82
G. A. Gontcharov, A. V. Mosenkov, S. S. Savchenko +6
We have applied the method of star counts with Wolf diagrams to determine the interstellar extinction in five Galactic cirri in Sloan Digital Sky Survey (SDSS) Stripe 82. For this…
