The Twentieth Data Release of the Sloan Digital Sky Survey: First All-Sky BOSS Spectra, eROSITA-SDSS-V Mapper Coordinated Observations, and a Preview of the Local Volume Mapper
SDSS Collaboration, Mojgan Aghakhanloo, David Aguilar +273
This paper presents the twentieth data release (DR20) from the Sloan Digital Sky Survey, the third data release of its fifth generation (SDSS-V). SDSS-V is a panoptic spectroscopy…
When bars and spirals conspire: recurrent build-up of the nuclear regions of disc galaxies
Tristan Boin, Sergey Khoperskov, Paola Di Matteo +6
The assembly history of the central regions of disc galaxies is regulated by dynamical processes that trigger gas infall events, leading to active star formation in nuclear stellar…
Winding, Unwinding, Rewinding the Gaia Phase Spiral
Neige Frankel, Marcin Semczuk, Teresa Antoja +10
The Gaia Space Satellite has transformed the field of Galactic Dynamics by collecting 6D phase space information for hundreds of millions of stars. In 2018, it enabled the discover…
Bar-spiral interaction produces radial migration and star formation bursts
Léa Marques, Ivan Minchev, Bridget Ratcliffe +8
Central bars and spirals are known to strongly impact the evolution of their host galaxies, both in terms of dynamics and star formation. Their typically different pattern speeds c…
ISM metallicity variations across spiral arms in disk galaxies: the impact of local enrichment and gas migration in the presence of radial metallicity gradient
Sergey Khoperskov, Evgenia Sivkova, Anna Saburova +4
Chemical abundance variations in the ISM provide important information about the galactic evolution, star-formation and enrichment histories. Recent observations of disk galaxies s…
Global enhancement and structure formation of the magnetic field in spiral galaxies
S. A. Khoperskov, S. S. Khrapov
We study numerically large-scale magnetic field evolution and its enhancement in gaseous disks of spiral galaxies. We consider a set of models with the various spiral pattern param…
Disk heating and bending instability in galaxies with counterrotation
Sergey Khoperskov, Giuseppe Bertin
With the help of high-resolution long-slit and integral-field spectroscopy observations, the number of confirmed cases of galaxies with counterrotation is increasing rapidly. The e…
Synthetic HI observations of spiral structure in the outer disk in galaxies
S. A. Khoperskov, G. Bertin
By means of 3D hydrodynamical simulations, in a separate paper we have discussed the properties of non-axisymmetric density wave trains in the outermost regions of galaxy disks, ba…
Spiral density waves in the outer galactic gaseous discs
S. A. Khoperskov, G. Bertin
Deep HI observations of the outer parts of disc galaxies demonstrate the frequent presence of extended, well-developed spiral arms far beyond the optical radius. To understand the…
Dynamics of Gaseous Disks in a Non-axisymmetric Dark Halo
A. V. Khoperskov, M. A. Eremin, S. A. Khoperskov +2
The dynamics of a galactic disk in a non-axisymmetric (triaxial) dark halo is studied in detail using high-resolution, numerical, hydrodynamical models. A long-lived, two-armed spi…
