Detection of a Star Forming Galaxy in the Center of a Low-Mass Galaxy Cluster

, 2018
Brightest Cluster Galaxies (BCGs) residing in the centers of galaxy clusters are typically quenched giant ellipticals. A recent study hinted that star-forming galaxies with large disks, so-called superluminous spirals and lenticulars, are the BCGs of a ...

Ionized gas outflow in the isolated S0 galaxy NGC 4460

, 2010
We use integral-field and long-slit spectroscopy to study the bright extended nebulosity discovered in the isolated lenticular galaxy NGC 4460 during a recent H-alpha survey of nearby galaxies.

Statistical study of warps in a sample of spiral and lenticular galaxies

NRIAG Journal of Astronomy and Geophysics, 2016
AbstractA sample of edge-on (or nearly edge-on) spiral and lenticular galaxies is selected to study the warp phenomenon in their disks. This sample contains 36 disk galaxies selected from Watanabe’s catalogue (Watanabe, 1983). We investigate the existence of physical relations between photometric and spectroscopic parameters and the warp degree of ...

What Are S0 Galaxies?

, 2009
The data collected in the Shapley-Ames catalog of bright galaxies show that lenticular (S0) galaxies are typically about a magnitude fainter than both elliptical (E) and early spiral (Sa) galaxies.

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,

1.65 micron (H-band) surface photometry of galaxies. VIII: the near-IR k-space at z=0

, 2002
We present the distribution of a statistical sample of nearby galaxies in the k-space (k1 ~ log M, k2 ~ log Ie, k3 ~ log M/L). Our study is based on near-IR (H-band: lambda = 1.65 micron) observations, for the first time comprising early- and late-type ...

Inner Polar Rings in Regular Lenticular Galaxies

The Astronomical Journal, 2004
We have investigated a sample of S0 galaxies, mostly with circumnuclear dust lanes orthogonal to their major axes, chosen from Hubble Space Telescope Wide Field Planetary Camera 2 images. Two-dimensional spectroscopy undertaken with the Multipupil Fiber Spectrograph of the 6 m telescope of the Special Astrophysical Observatory of the Russian Academy of

Morphology and kinematics of the ionised gas in early-type galaxies

, 2005
We present results of our ongoing study of the morphology and kinematics of the ionised gas in 48 representative nearby elliptical and lenticular galaxies using the SAURON integral-field spectrograph on the 4.2m William Herschel Telescope.
