1. The Radial Distribution of the Interstellar Medium in Disk Galaxies: Evidence
One possible way for spiral galaxies to internally evolve would be for gas to flow to the center and form stars in a central disk (pseudo-bulge). ... In this paper we present radial profiles of stellar and 8 ЮМm emission from polycyclic aromatic hydrocarbons (PAHs) for 11 spiral galaxies to investigate whether the interstellar medium in these galaxies contains a central concentration above that expected from the exponential disk. ...

A histogram of the systemic velocities of the brightest HIPASS galaxies is shown in Fig. ... It peaks, as expected, in the interval 800 to 2000 km/s. No bright galaxies were found with systemic velocities of less than -350 or more than 5500 km/s. Figure 2: Histogram of the H I systemic velocities of the brightest galaxies obtained from HIPASS. ...

7. Measurement of the dark halo shape in polar ring galaxies
... 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. ...

11. Informational system "Evolution of RG"
The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...

13. Search for distant radio galaxies in SAO
... 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. ...

15. http://www.mso.anu.edu.au/seminars/abstracts/20160301-1100.html
Since the first stars and then galaxies formed the Universe has been an immense factory converting neutral gas into stellar material. ... In this seminar I will discuss recent results from the Galaxy And Mass Assembly (GAMA) survey, probing the assembly of stellar mass though both in-situ star formation (as traced by multiple SFR indicators) and interactions (both mergers and interaction induced star-formation) - in galaxies spanning ~4 decades in stellar mass. ...

17. Clustering Analysis Algorithms and Their Applications to Digital POSS-II
... We report on the preliminary results of experiments using a Bayesian cluster method to cluster objects present in photographic images of the POSS-II. ... We believe that the application of such algorithms to large-scale astronomical sky surveys can aid in cataloging the detected objects, and may even have the potential to discover new categories of objects. ... We have thus started to explore new clustering analysis and unsupervised classification techniques for this task. ...
