Giant Low-Surface Brightness Galaxies in the Global Picture of Galaxy Formation and Evolution

Fedor M. Kolganov, Igor V. Chilingarian, Anna S. Saburova +5

Giant low-surface brightness galaxies (gLSBGs) challenge standard merger-driven galaxy assembly models due to their large, dynamically cold disks, with radii often larger than 100~…

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…

Optical Emission-Line Properties of eROSITA-selected SDSS-V Galaxies

Nadiia G. Pulatova, Evgenii Rubtsov, Igor V. Chilingarian +21

We present and discuss optical emission line properties obtained from the analysis of Sloan Digital Sky Survey (SDSS) spectra for an X-ray selected sample of 3684 galaxies (0.002 <…

The Nineteenth Data Release of the Sloan Digital Sky Survey

SDSS Collaboration, Gautham Adamane Pallathadka, Mojgan Aghakhanloo +210

Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial…

Broad line region echo from highly accreting intermediate-mass black hole candidate SDSS J144850.08+160803.1. The first probe of intra-night variability and reverberation mapping

Mariia Demianenko, Anton Afanasiev, Evgenii Rubtsov +8

Elusive intermediate-mass black holes (IMBHs) can be used as ``time-squeezing'' machines, enabling studies of AGN geometry via reverberation mapping on much shorter timescales than…

Optical spectroscopy of host-galaxies of intermediate mass black holes: evolution of central black holes

V. Goradzhanov, I. Chilingarian, M. Demianenko +6

Intermediate-mass black holes (IMBHs) with masses below () are pivotal in understanding the origin and growth mechanisms of supermassive black holes (SMBHs…

A closer look at the extended edge-on low-surface brightness galaxies

Anna S. Saburova, Damir Gasymov, Evgenii V. Rubtsov +13

To understand the origin of extended disks of low-surface brightness (LSB) galaxies, we studied in detail 4 such systems with large disks seen edge-on. Two of them are edge-on gian…

Optical Variability of "Light-weight" Supermassive Black Holes at a Few Percent Level from ZTF Forced-Photometry Light Curves

Mariia Demianenko, Kirill Grishin, Victoria Toptun +4

Large time-domain surveys provide a unique opportunity to detect and explore variability of millions of sources on timescales from days to years. Broadband photometric variability…
