The Newtonian and MOND dynamical models of NGC 5128: Investigation of the dark matter contribution [PDF]
Serbian Astronomical Journal, 2016 We study the well-known nearby early-type galaxy NGC 5128 (Centaurus A) and use the sample of its globular clusters to analyze its dynamics. We study both Newtonian and MOND models assuming three cases of orbital anisotropies: isotropic case ...

The Study of Nebular Emission on Nearby Spiral Galaxies in the IFU Era
Advances in Astronomy, Volume 2013, Issue 1, 2013., 2013 A new generation of wide‐field emission‐line surveys based on integral field units (IFU) is allowing us to obtain spatially resolved information of the gas‐phase emission in nearby late‐type galaxies, based on large samples of HII regions and full two‐dimensional coverage.

Implications and Applications of Kinematic Galaxy Scaling Relations
International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012 Galaxy scaling relations, which describe a connection between ostensibly unrelated physical characteristics, testify to an underlying order in galaxy formation that requires understanding. I review the development of a scaling relation that (1) unites the well‐known fundamental plane (FP) relation of giant elliptical galaxies and Tully‐Fisher (TF ...

Investigating the Correlations between Physical Parameters of Elliptical and Lenticular Galaxies
Iraqi Journal of ScienceThis study aims to investigate the features of stellar-gaseous kinematics and dynamics mass using scaling coefficient relationships (such as the Faber–Jackson relation (FJR)) of two samples of elliptical and lenticular galaxies.

The Baryonic Halos of Isolated Elliptical Galaxies
Galaxies, 2017 Without the interference of a number of events, galaxies may suffer in crowded environments (e.g., stripping, harassment, strangulation); isolated elliptical galaxies provide a control sample for the study of galaxy formation.

The Origin of Star-forming Rings in S0 Galaxies
The Astrophysical Journal, 2023 Spatially resolved integral field spectroscopic maps in a sample of 532 S0 galaxies from the MaNGA survey have unveiled the existence of inner rings (〈 R 〉 ∼ 1 R _e ) betraying ongoing star formation in a number of these objects.

Luminosities of Barred and Unbarred S0 Galaxies [PDF]
, 2012 Lenticular galaxies with M_B < -21.5 are almost exclusively unbarred, whereas both barred and unbarred objects occur at fainter luminosity levels. This effect is observed both for objects classified in blue light, and for those that were classified in the infrared.

The influence of environment in the formation of lenticular galaxies
, 2021 Lenticular galaxies (S0s) are believed to form through 2 main pathways: mergers or fading of a spiral progenitor. It is not clear yet what is the dominant scenario, nor what are the parameters and physical conditions that favor one path instead of the other. In a pilot study with 21 galaxies (Coccato et al.

Globular clusters and planetary nebulae kinematics and X-ray emission in the early-type galaxy NGC 5128 [PDF]
Serbian Astronomical Journal, 2006 The estimates of the mass of the galaxy NGC 5128 based on the different mass tracers, globular clusters (GCs) and planetary nebulae (PNe), are presented.

Outer Rings in Early-type Galaxies: From Vorontsov-Velyaminov to Present
Open Astronomy, 2014 ‘Ringed galaxies’, or disk galaxies with prominent outer ring structures, separated visually from the main galactic bodies, were discovered and intensively studied by B. A. Vorontsov-Vel’yaminov whose 110th anniversary is celebrated this year. We discuss
