Exploring Dark Matter Properties from the Smallest to the Largest Scales
Bradač, Maruša (2004)One of the main problems in cosmology is to understand the formation and evolution of galaxies, galaxy clusters, and large-scale structure. Whereas the basics of the current Cold Dark Matter (CDM) paradigm for structure ... -
From galaxies to the cosmic web and back: the interplay of different scales in galaxy formation and cosmic reionization
Garaldi, Enrico (2020-10-08)The evolution of the Universe is primarily governed by gravity, that triggers the development of a complex web-like distribution of galaxies. The latter are embedded in larger structures, called haloes, mainly composed by ... -
Old Globular Clusters in Dwarf Irregular Galaxies
Georgiev, Iskren Y. (2008)<p>One of the most pressing questions in astrophysics to date is resolving the history of galaxy assembly and their subsequent evolution. In the currently popular hierarchical merging” scenario, massive galaxies are believed ... -
A radio view on the structural evolution of massive star-forming galaxies across cosmic time
Jiménez-Andrade, Eric Faustino (2020-03-06)It is not well understood what processes regulate the global formation of stars in galaxies throughout cosmic history. My work aims to measure the structural evolution of star-forming galaxies (SFGs), from the present back ... -
Stellar populations in gravitationally bound systems
Jeřábková, Tereza (2020-08-21)The understanding of how, which, where and when stars form provides important information for the vast majority of astronomical fields. Star-formation has a complex multi-scale physical nature. Stars form in dense sub-parsec ... -
A Unified Formation Scenario for the Zoo of Extended Star Clusters and Ultra-Compact Dwarf Galaxies
Brüns, Renate Claudia (2014-07-18)In the last decade, very extended old stellar clusters, which cover a large mass range, have been found in various types of galaxies in different environments. Objects with masses comparable to normal globular clusters ... -
Weak Gravitational Lensing and Galaxy Bias
Simon, Patrick (2005)Galaxies were formed from primordial baryonic matter within the gravitational potential of the dark matter. Today a confusing wealth of different galaxy populations is known. Explaining the emergence of this zoo of galaxy ...
