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 ...

Measurement of the Lick Indices in Early-Type Galaxies: Line-of-Sight Velocity Distribution Corrections for IC 1459 [PDF]

Serbian Astronomical Journal, 2009
In this paper we analyse the measurements of the absorption line-strength Lick indices in the early-type galaxy IC 1459. We use thelong-slit spectra of the elliptical galaxy IC 1459 from which its kinematicshad previously been extracted to calculate ...

Star Formation in the Lopsided Galaxy Arp 291

The 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 ...

Understanding the Fundamental Plane and the Tully Fisher Relation

Frontiers in Astronomy and Space Sciences, 2020
The relation between early type galaxy size, surface brightness and velocity dispersion, “the fundamental plane,” has long been understood as resulting from equilibrium in their largely pressure supported stellar dynamics.

Lenticular galaxies - the one in the middle

, 2016
The lenticular (S0) galaxies introduced by Hubble (1936) as a morphological transition class between elliptical and early-type spiral galaxies, which have the most massive bulges among disk galaxies, may have formed in several different ways as suggested by theoretical and numerical simulation studies.

The Quasar / Galaxy Pair PKS 1327-206 / ESO 1327-2041: Absorption Associated with a Recent Galaxy Merger

, 2010
We present HST/WFPC2 broadband and ground-based Halpha images, H I 21-cm emission maps, and low-resolution optical spectra of the nearby galaxy ESO 1327-2041, which is located 38 arcsec (14 kpc in projection) west of the quasar PKS 1327-206.

Stellar Populations in Nearby Lenticular Galaxies

The Astrophysical Journal, 2006
We have obtained 2D spectral data for a sample of 58 nearby S0 galaxies with the Multi-Pupil Spectrograph of the 6m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences. The Lick indices H-beta, Mgb, and are calculated separately for the nuclei and for the bulges taken as the rings between R=4" and 7"; and the ...

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
