Misaligned Gas Acquisition as a Formation Pathway of S0 Galaxies

open access: yesThe 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.

A Complex Stellar Line-of-Sight Velocity Distribution in the Lenticular Galaxy NGC 524

open access: yesOpen Astronomy, 2011
We present a detailed study of the stellar and gaseous kinematics in the luminous early-type galaxy NGC 524, derived from the long-slit spectroscopic observations obtained with the Russian 6 m telescope and the IFU data from the SAURON survey.

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

open access: yesThe 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.

Formation of the Dark Matter–Deficient S0 Galaxy NGC 4111 under the Tidal Interactions

open access: yesThe Astrophysical Journal Letters
We present high-sensitivity and large-scale atomic hydrogen (H i ) observations toward lenticular (S0) galaxy NGC 4111 using the Five-hundred-meter Aperture Spherical Radio Telescope.

The star formation history of early-type galaxies in the fornax cluster [PDF]

open access: yes, 1998
We have measured central line strengths and line-strength gradients for a complete sample of early-type galaxies in the Fornax cluster, comprising 11 elliptical and 11 lenticular galaxies, more luminous than M(_B) = -17.

The assembly histories of lenticular galaxies from their large radii kinematic profiles

open access: yes, 2022
The thesis provides a contribution to understanding the nature of lenticular galaxies in low-density environments from the analysis of the stellar, globular cluster and planetary nebulae kinematics reaching out to the outskirts of the galaxies, which are

Star Formation in the Lopsided Galaxy Arp 291

open access: yesThe Astrophysical Journal
We have investigated the star formation process taking place in the lopsided galaxy Arp 291, based on narrowband images in the H α , [N ii ] λ 6583, and [O iii ] λ 5007 emission lines, obtained using the modern tunable photometer MaNGaL at the Caucasus ...

Stellar counter-rotation in lenticular galaxy NGC 448 [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2016
The counter-rotation phenomenon in disc galaxies directly indicates a complex galaxy assembly history which is crucial for our understanding of galaxy physics. Here we present the complex data analysis for a lenticular galaxy NGC 448, which has been recently suspected to host a counter-rotating stellar component.

The influence of environment in the formation of lenticular galaxies

open access: yes, 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.

Detection of a Superluminous Spiral Galaxy in the Heart of a Massive Galaxy Cluster

open access: yes, 2022
It is well established that brightest cluster galaxies (BCGs), residing in the center of galaxy clusters, are typically massive and quenched galaxies with cD or elliptical morphology.
