A new method for the identification of non-gaussian line profiles in elliptical galaxies . ... It is usually assumed that the line profiles (i.e., the distributions of stars over line-of-sight velocities) of elliptical galaxies have Gaussian shapes, characterized by a line strength gamma, mean radial velocity V, and velocity dispersion sigma. ... Approximating these line profiles by Gaussians yields systematic errors in the estimates of the mean radial velocity and velocity dispersion of 10% or more. ...

... All the galaxies are divided into 4 groups depending on the environment type; every subsample contains more than 10 galaxies. ... An effect of environments is seen both for the nuclei and for the bulges: if we consider the clusters (Virgo and Ursa Ma jor) and group centers as dense environments and the field and group periphery as sparse environments, then in the dense environments the stellar populations of S0s are in average older by 4­5 Gyr than in the sparse ones. ...

... Interacting galaxies . ... Catalogues . ... We define a volume limited sample of over 14,000 early-type galaxies (ETGs) selected from data release six of the Sloan Digital Sky Survey. The density of environment of each galaxy is robustly measured. By comparing narrow band spectral line indices with recent models of simple stellar populations (SSPs) we investigate trends in the star formation history as a function of galaxy mass (velocity dispersion), density of environment and galactic radius. ...

... In this paper we present the results of detailed B, V, R, I, and H study of the isolated nearby blue compact dwarf (BCD) galaxy NGC6789. Judging from the literature the observed galaxy has not been resolved into stars up to now. ... The distance of the galaxy, estimated from the tip of the red giant branch (TRGB) is 2.1 Mpc which places NGC6789 close to the Local Group. ...

... Line radiative transfer in C 18 O, HCO + , and CS lines is considered in a spherically symmetric chemo-dynamical model of a starless core, evolution of which is driven by the ambipolar diffusion. Theoretical line profiles are compared to observational data on the well-known L1544 core, which is one of possible candidates for collapsing protostellar clouds. ... Comparison between modelled and observed spectra suggests that L1544 has flattened structure and is observed at some inclination. ...
