CDM, Feedback and the Hubble Sequence [PDF]

, 2002
We have performed TreeSPH simulations of galaxy formation in a standard LCDM cosmology, including effects of star formation, energetic stellar feedback processes and a meta-galactic UV field, and obtain a mix of disk, lenticular and elliptical galaxies ...

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.

The Quasar / Galaxy Pair PKS 1327-206 / ESO 1327-2041: Absorption Associated with a Recent Galaxy Merger

, 2010
We present HST/WFPC2 broadband and ground-based Halpha images, H I 21-cm emission maps, and low-resolution optical spectra of the nearby galaxy ESO 1327-2041, which is located 38 arcsec (14 kpc in projection) west of the quasar PKS 1327-206.

The Galaxy Population of Abell 1367: The Stellar Mass-Metallicity Relation

, 2011
Using wide baseline broad-band photometry, we analyse the stellar population properties of a sample of 72 galaxies, spanning a wide range of stellar masses and morphological types, in the nearby spiral-rich and dynamically young galaxy cluster Abell 1367.

Synchronous Evolution of Galaxies in Groups: NGC 524 Group

, 2012
By means of panoramic spectroscopy at the SAO RAS BTA telescope, we investigated the properties of stellar populations in the central regions of five early-type galaxies -- the NGC 524 group members. The evolution of the central regions of galaxies looks

Stellar Populations in Nearby Lenticular Galaxies

The Astrophysical Journal, 2006
We have obtained 2D spectral data for a sample of 58 nearby S0 galaxies with the Multi-Pupil Spectrograph of the 6m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences. The Lick indices H-beta, Mgb, and are calculated separately for the nuclei and for the bulges taken as the rings between R=4" and 7"; and the ...

Misaligned Gas Acquisition as a Formation Pathway of S0 Galaxies

The Astrophysical Journal
We analyze a sample of 753 S0 galaxies from the MPL-10 of Mapping Nearby Galaxies at Apache Point Observatory survey and investigate the gas–star kinematic misalignment and merger remnant fraction in galaxies with different morphological types.
