General Physical Properties of Gamma-Ray-emitting Radio Galaxies
The Astrophysical Journal Supplement Series, 2023 We study the radio galaxies with known redshifts detected by the Fermi satellite after 10 yr of data (4FGL-DR2). We use a one-zone leptonic model to fit the quasi-simultaneous multiwavelength data of these radio galaxies and study the distributions of ...

Chemodynamical modeling of young disk galaxies [PDF]
, 2003 Disk galaxies are very complex systems consisting of several components like the bulge, the disk and the halo. Additionally, substructures like extended HI disks, thin and thick stellar disks are observed.

Galaxy morphology classification: are stellar circularities enough? [PDF]
Serbian Astronomical JournalWe present a preliminary study exploring whether the stellar orbital circularity of simulated galaxies, available from precomputed catalogs in the IllustrisTNG project, can be used as a proxy for a broad morphological classification. We focus on

On the scaling relations of disk galaxies [PDF]
Proceedings of the International Astronomical Union, 2012 AbstractThe physical background of scaling laws of disk galaxies is reviewed. The match between analytically derived and observed scaling laws is briefly discussed. Accurate modeling of the fraction of baryons that end up populating a disk, and the conversion efficiency of those into stars, remains a challenging task for numerical simulations.

, 2008 We present a new set of multi-million particle SPH simulations of the formation of disk dominated galaxies in a cosmological context. Some of these galaxies are higher resolution versions of the models already described in Governato et al (2007). To correctly compare simulations with observations we create artificial images of our simulations and from ...

Kinematic Modeling of Distant Galaxies
Open Astronomy, 2012 Evolution of galaxies is one of the most actual topics in astrophysics. Among the most important factors determining the evolution are two galactic components which are difficult or even impossible to detect optically: the gaseous disks and the dark ...

GASP and MaNGA Surveys Shed Light on the Enigma of the Gas Metallicity Gradients in Disk Galaxies [PDF]
, 2021 Making use of both MUSE observations of 85 galaxies from the survey GASP (GAs Stripping Phenomena in galaxies with MUSE) and a large sample from MaNGA (Mapping Nearby Galaxies at Apache Point Observatory survey), we investigate the distribution of gas ...

Identifying lopsidedness in spiral galaxies using a deep convolutional neural network
Astronomy & AstrophysicsContext. About 30% of disk galaxies exhibit lopsidedness in their stellar disk. Although such a large-scale asymmetry in the disk can be primarily considered as a long-lived mode (m = 1), the physical origin of the lopsidedness in the disk continues to ...
