A particularly exciting period has arrived for studying the overall properties of the Universe. A wire range of ground and space experiments are gathering an unprecedented amount of high-quality data, which allow us to tackle some of the most interesting and fundamental physical problems: the nature of dark energy and dark matter, the properties of the early Universe and structure formation from the scale of galaxies to the scale of the largest known matter configurations, galaxy superclusters and filaments.
Galaxies are the largest single objects in the Universe. Within them, some of the most important processes take place: the circulation of the cosmic material from gas to stars and back, resulting in the enrichment of matter with various chemical elements. In our galaxy physics team we study the structure and composition of both local and distant galaxies. We also consider the influence of neighbouring galaxies and the general distribution of the surrounding matter on the evolution of galaxies.
The main research area of cosmology are groups and clusters and the algorythms of determining them; superclusters and filaments. Here we will state the papers worth mentioning in every field. All of the relevant papers of our cosmology researchers can be read here.
During the past five years, the research projects in galaxy physics have been connected to four major topics: cold hydrogen clouds, Andromeda galaxy, galaxy bulge-disk decomposition, and how the galaxy's qualities depend on the qualities of the group or cluster.
