Globular Clusters in Lenticular Galaxies: NGC 3115 [PDF]

Symposium - International Astronomical Union, 1988
We present a progress report for the ongoing study of the globular cluster (GC) system around the edge-on lenticular galaxy NGC 3115. This object is one of the best targets for this kind of investigation, due to its proximity (~ 10 Mpc) and favourable inclination (for a deep photometric study and a review of the properties of NGC 3115, see Capaccioli ...

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.

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

Open 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.

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 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 Cool ISM in Elliptical Galaxies. II. Gas Content in the Volume - Limited Sample and Results from the Combined Elliptical and Lenticular Surveys

, 2010
We report new observations of atomic and molecular gas in a volume limited sample of elliptical galaxies. Combining the elliptical sample with an earlier and similar lenticular one, we show that cool gas detection rates are very similar among low ...

Testing the nature of S0 galaxies using planetary nebula kinematics in NGC 1023 [PDF]

, 2007
We investigate the manner in which lenticular galaxies are formed by studying their stellar kinematics: an S0 formed from a fading spiral galaxy should display similar cold outer disc kinematics to its progenitor, while an S0 formed in a minor merger ...

KINEMATICS AND STELLAR POPULATIONS IN ISOLATED LENTICULAR GALAXIES

The Astronomical Journal, 2015
By combining new long-slit spectral data obtained with the Southern African Large Telescope (SALT) for 9 galaxies with previously published our observations for additional 12 galaxies we study the stellar and gaseous kinematics as well as radially resolved stellar population properties and ionized gas metallicity and excitation for a sample of isolated
