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

Monthly 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.

Inner structure of the lenticular galaxy NGC 3384 [PDF]

Monthly Notices of the Royal Astronomical Society, 1984
La region interne de la galaxie lenticulaire NGC 3384 presente une structure complexe. La haute resolution (FWHM≃0,7 arc sec) obtenue pour cette etude photometrique permet de montrer que la faible structure allongee croisant le bulbe perpendiculairement a l'axe principal de la galaxie n'est probablement pas une barre, mais un petit anneau polaire de ...

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 ...

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

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.

GALEX UV Color Relations for Nearby Early-Type Galaxies [PDF]

, 2006
We use GALEX/optical photometry to construct color-color relationships for early-type galaxies sorted by morphological type. We have matched objects in the GALEX GR1 public release and the first IR1.1 internal release, with the RC3 early-type galaxies ...

A catalog of warps in spiral and lenticular galaxies in the Southern hemisphere [PDF]

Astronomy & Astrophysics, 2003
A catalog of optical warps of galaxies is presented. This can be considered complementary to that reported by Sanchez-Saavedra et al., with 42 galaxies in the northern hemisphere, and to that by Reshetnikov & Combes, with 60 optical warps. The limits of the present catalog are: logr25 > 0.60, B_{t} < 14.5, delta(2000) < 0, -2.5 < t <

A Chandra Observation of the Nearby Lenticular Galaxy NGC 5102: Where are the X-ray Binaries?

, 2005
We present results from a 34 ks Chandra/ACIS-S observation of the nearby (d=3.1 Mpc) lenticular galaxy NGC 5102, previously shown to have an unusually low X-ray luminosity.

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 SLUGGS survey: chromodynamical modelling of the lenticular galaxy NGC 1023 [PDF]

Monthly Notices of the Royal Astronomical Society, 2015
Globular clusters (GCs) can be considered discrete, long-lived, dynamical tracers that retain crucial information about the assembly history of their parent galaxy. In this paper, we present a new catalogue of GC velocities and colours for the lenticular galaxy NGC 1023, we study their kinematics and spatial distribution, in comparison with the ...
