STELLAR NUCLEI AND INNER POLAR DISKS IN LENTICULAR GALAXIES [PDF]

The Astronomical Journal, 2016
ABSTRACT I analyze statistics of the stellar population properties for stellar nuclei and bulges of nearby lenticular galaxies in different environments by using panoramic spectral data of the integral-field spectrograph SAURON retrieved from the open archive of the Isaac Newton Group.

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

The total mass of the early-type galaxy NGC 4649 (M60) [PDF]

Serbian Astronomical Journal, 2008
In this paper the problem of the total mass and the total mass-to-light ratio of the early-type galaxy NGC 4649 (M60) is analyzed. Use is made of two independent techniques: the X-ray methodology which is based on the temperature of the X-ray halo of NGC

Star formation histories of dwarf lenticular galaxies

Monthly Notices of the Royal Astronomical Society
ABSTRACT Star formation histories (SFHs) are essential for understanding galaxy formation and evolution. We present the mean SFHs of 148 dwarf lenticular galaxies (dS0s) derived from the Sloan Digital Sky Survey spectra. These SFHs reveal two distinct periods of active star formation. The first period, concluding approximately 6 Gyr ago,

Mass Stratification in the Globular Cluster System Revealing the Assembly History of the Nearest S0 Galaxy NGC 3115

The Astrophysical Journal
Galaxy formation and evolution are hierarchical. The most massive galaxies are thought to form their central regions early through violent dissipational processes, then grow inside-out by accreting smaller satellites.
