Creating lenticular galaxies with mergers [PDF]
Proceedings of the International Astronomical Union, 2016 Lenticular galaxies (S0s) represent the majority of early-type galaxies in the local Universe, but their formation channels are still poorly understood.

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.

Hot Gaseous Halos in Early Type Galaxies
Galaxies, 2017 The hot gas in early type galaxies (ETGs) plays a crucial role in their formation and evolution. As the hot gas is often extended to the outskirts beyond the optical size, the large scale structural features identified by Chandra (including cavities ...

Dark matter in massive early-type galaxies: 100 years of the jeans equations [PDF]
Serbian Astronomical Journal, 2019 In 1919 James Jeans published the book Problems of Cosmogony and Stellar Dynamics in which he summarized his work on dynamics of stellar systems based on his papers published from 1915 onwards.

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.

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 ...

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.

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.

KINEMATICS AND STELLAR POPULATIONS IN ISOLATED LENTICULAR GALAXIES [PDF]
, 2015 By combining new long-slit spectral data obtained with the Southern African Large Telescope for nine galaxies with our previously published observations for 12 additional galaxies, we study the stellar and gaseous kinematics as well as radially resolved ...

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
