NGC 6340: an old S0 galaxy with a young polar disc. Clues from morphology, internal kinematics and stellar populations

, 2009
Lenticular galaxies are believed to form by a combination of environmental effects and secular evolution. We study the nearby disc-dominated S0 galaxy NGC 6340 photometrically and spectroscopically to understand the mechanisms of S0 formation and ...

Grigori Kuzmin and Stellar Dynamics

Open Astronomy, 2011
Grigori Kuzmin was a very gifted dynamicist and one of the towering figures in the distinguished history of the Tartu Observatory. He obtained a number of important results in relative isolation which were later rediscovered in the West.

Neutral hydrogen in nearby elliptical and lenticular galaxies: the continuing formation of early-type galaxies

Monthly Notices of the Royal Astronomical Society, 2006
(Abridged) We present deep WSRT observations of neutral hydrogen in 12 nearby elliptical and lenticular galaxies. The selected objects come from a representative sample of nearby galaxies earlier studied at optical wavelengths with the integral-field spectrograph Sauron.

Creating S0s with Major Mergers: A 3D View

Galaxies, 2015
A number of simulators have argued that major mergers can sometimes preserve discs, but the possibility that they could explain the emergence of lenticular galaxies (S0s) has been generally neglected.

Isolated lenticular galaxies: properties and evolution

, 2014
This work is dedicated to investigation of galaxies that do not fit into a common scenario of galaxy formation - isolated lenticular galaxies. We have studied stellar populations and ionized gas content of a sample of 22 lenticular galaxies (among those 4 targets have appeared to be of erroneous morphological classification) by undertaking deep long ...

Planetary nebulae as tracers of accreted stellar populations in massive galaxies in groups and clusters

Frontiers in Astronomy and Space Sciences
Planetary nebulae (PNe) are valuable spatial and kinematic tracers of nearby galaxies. In this mini-review, I focus on their role in tracing the halo and intra-cluster/intra-group light assembly in groups and clusters of galaxies within 100 Mpc and, in ...

Multi-spin stellar velocity maps of the most massive galaxies

Astronomy & Astrophysics
We present stellar kinematics of the MUSE Most Massive Galaxies (M3G) Survey, comprising 25 galaxies brighter than −25.7 mag in the Ks band and stellar masses above ≈6 × 1011 M⊙.

Spectroscopic bulge-disc decomposition: a new method to study the evolution of lenticular galaxies

, 2012
A new method for spectroscopic bulge-disc decomposition is presented, in which the spatial light profile in a two-dimensional spectrum is decomposed wavelength-by-wavelength into bulge and disc components, allowing separate one-dimensional spectra for ...

Shape of the Galactic Orbits in Clusters

, 1998
A kinematical analysis applied to a sample of galaxy clusters indicates that the differences between the velocity distribution of elliptical and spiral galaxies are associated with the shape of their orbit families.

Exponential bulges and antitruncated disks in lenticular galaxies [PDF]

Proceedings of the International Astronomical Union, 2008
AbstractThe presence of exponential bulges and anti-truncated disks has been noticed in many lenticular galaxies. In fact, it could be expected because the very formation of S0 galaxies includes various processes of secular evolution. We discuss how to distinguish between a pseudobulge and an anti-truncated disk, and also what particular mechanisms may
