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…
Website with interactive visualization of multivariate astronomical time series
M. Volkov, M. Demianenko, D. Matveev +2
Light curves represent astronomical time series of flux measured across one or more photometric bands. With the rapid growth of large-scale sky surveys, time-domain astronomy has b…
MUSE Study of Two Giant Low-surface-brightness Galaxies with Compact Satellites
Anna S. Saburova, Damir Gasymov, Ivan S. Gerasimov +7
Giant low-surface-brightness disk galaxies (gLSBGs) are rare objects with disk radii up-to 160 kpc and dynamical masses of an order of up to 10 . Their very exist…
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…
Sloan Digital Sky Survey-V: Pioneering Panoptic Spectroscopy
Juna A. Kollmeier, Hans-Walter Rix, Conny Aerts +217
The Sloan Digital Sky Survey-V (SDSS-V) is pioneering panoptic spectroscopy: it is the first all-sky, multi-epoch, optical-to-infrared spectroscopic survey. SDSS-V is mapping the s…
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…
What is the Role of Large Language Models in the Evolution of Astronomy Research?
Morgan Fouesneau, Ivelina G. Momcheva, Urmila Chadayammuri +10
ChatGPT and other state-of-the-art large language models (LLMs) are rapidly transforming multiple fields, offering powerful tools for a wide range of applications. These models, co…
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…
What excites the optical emission in X-ray-selected galaxies?
N. G. Pulatova, H. -W. Rix, A. V. Tugay +3
We present a study of galaxies at with detected nuclear X-ray emission and optical emission line diagnostics in the Baldwin-Phillips-Terlevich (BPT) diagram. This s…
PSF quality metrics in the problem of revealing Intermediate-Mass Black Holes using MICADO@ELT
Mariia Demianenko, Joerg-Uwe Pott, Kai Polsterer
Nowadays, astronomers perform point spread function (PSF) fitting for most types of observational data. Interpolation of the PSF is often an intermediate step in such algorithms. I…
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…
