Lenticular Galaxies and Their Environments [PDF]

The Astrophysical Journal, 2009
It is widely believed that lenticular (S0) galaxies were initially spirals from which the gas has been removed by interactions with hot cluster gas, or by ram-pressure stripping of cool gas from spirals that are orbiting within rich clusters of galaxies.

PGC 44685: A Dwarf Star-forming Lenticular Galaxy with a Wolf–Rayet Population

The Astrophysical Journal
Lenticular galaxies (S0s) are formed mainly from the gas stripping of spirals in the cluster. But how S0s form and evolve in the field is still in need of being resolved.

NGC 404, A Rejuvenated Lenticular Galaxy on a Merger-Induced, Blueward Excursion into the Green Valley [PDF]

, 2010
We have discovered recent star formation in the outermost portion (1-4x R_25) of the nearby lenticular (S0) galaxy NGC 404 using GALEX UV imaging.

Exploring Lenticular Galaxy Formation in Field Environments Using NewHorizon: Evidence for Counterrotating Gas Accretion as a Formation Channel

The Astrophysical Journal
The formation pathways of lenticular galaxies (S0s) in field environments remain a matter of debate. We utilize the cosmological hydrodynamic simulation, NewHorizon , to investigate the issue. We select two massive star formation quenched S0s as our main

The lenticular galaxy NGC3607: stellar population, metallicity and ionised gas [PDF]

, 2009
In this work we derive clues to the formation scenario and ionisation source of the lenticular galaxy NGC 3607 by means of metallicity gradients, stellar population and emission lines properties.

Stellar and dust properties in a sample of blue early type galaxies [PDF]

Serbian Astronomical Journal, 2022
This paper presents a comparative study of physical properties of a sample of 89 blue early-type galaxies (ETGs) from the local universe by fitting SEDs to their multi-wavelength photometric and spectroscopic data.

Dynamical models of two lenticular galaxies: NGC 1023 and NGC 4526 [PDF]

Serbian Astronomical Journal, 2017
We study kinematics and dynamics of two lenticular galaxies that possess globular clusters (GCs) which extend beyond approximately seven effective radii. We analyze two nearby lenticular galaxies, NGC 1023 and NGC 4526, based on their GCs. We extract the

Elliptical galaxies: Rotationally distorted, after all [PDF]

Serbian Astronomical Journal, 2009
On the basis of earlier investigations on homeoidally striated Mac Laurin spheroids and Jacobi ellipsoids (Caimmi and Marmo 2005, Caimmi 2006a, 2007), different sequences of configurations are defined and represented in the ellipticity-rotation plane ...

Clustercentric Distance or Local Density? It Depends on Galaxy Morphology

The Astrophysical Journal, 2023
Determining which between projected local density and distance from the cluster center plays a major role in regulating morphological fractions in clusters is a longstanding debate.
