The spatial distribution of stars in the Local Group dwarf irregular galaxy NGC 6822 has been studied, using recent positions and deep photometry for about 15,000 stars in the galaxy. Based on photometrical data, OB stars and red stars could be studied separately. Spatial statistical tools have been applied to the analysis of the spatial structure. ...

... According to the most popular cosmological paradigm, the greater part of the galaxy mass is accumulated in the dark matter halo. ... The polar ring galaxies (PRGs) reveal external rings or disks of gas, dust and stars rotating in a plane roughly perpendicular to the disk of the central galaxy. ... The shape of the dark halo in the model was chosen so as to achieve the best fit to the observed rotation of both galaxies themselves and their polar rings. ... The SPRC-7 galaxy. ...

... The search for distant objects which can be both galaxies and quasars is one of the most important problems of observational astrphysics, because it allows one to determine cosmological parameters connected with the time of appearence and evolution of stellar systems, large scale structure of the Universe. ... Radio galaxies are important objects to be studied because they are sources of infrared-optical-ultraviolet continuum, emission lines and continual radio emission. ...

... Abstract: We present an extensive study of the radiative transfer in dusty galaxies based on Monte Carlo simulations. ... We have explored the dependence of A_l on a conspicuous set of quantities (Hubble type, inclination, dust optical thickness, dust distribution and extinction properties) for a large wavelength interval, ranging from 1250A to the K band, thus finally providing a comprehensive atlas of dust extinction in galaxies, which is electronically available. ...

... As a summary I present a probable model for the evolution of the nearby starburst galaxies by taking into account observations of their large-scale and nuclear gas dynamics as well as numerical simulations of gas flows in galaxies. ... Thus, it is very likely that galaxy interaction plays an important role in the formation of bars . ... A good example is the barred starburst galaxy NGC 1808. ... In fact, one can nearly see the gas flowing toward the galaxy centre where it fuels the nuclear starburst...

... Dark Matter Ring Modeled around Galaxy Cluster CL0024+17 . ... It is the relatively weak distortions of the many distant faint blue galaxies all over the image, however, that indicates the existence of the dark matter ring. ... A hypothesis for the formation of the huge dark matter ring holds that it is a transient feature formed when galaxy cluster CL0024+17 collided with another cluster of galaxies about one billion years ago, leaving a ring similar to when a rock is thrown in a pond. ...

... 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. ...

Constraining Galaxy Formation Epoch - Age Estimation of High Redshift Galaxies - S. Yi et al. Caltech, USA The galaxy formation epoch (z f ) is an important and unique prod- uct of cosmological models, and thus much e ort has been made to constrain it. The most direct way of constraining z f is to estimate the ages of bright elliptical galaxies at high redshifts arrucately, but it has not been an easy task. ... If we adopt our age estimate, the continuum of this galaxy suggests z f  2 { 3. ...
