Application of photometric redshifts on the correlation properties of galaxies and matter
Hildebrandt, Hendrik Jürgen (2007)In the past years cosmology, the science of the universe as a whole, has seen tremendous progress. The Lambda-Cold-Dark-Matter scenario is widely accepted as the standard model of cosmology describing the evolution of the ... -
Can the halo model describe 2nd- and 3rd-order correlation functions of gravitational lensing consistently?
Martin, Sandra Maria (2019-11-07)To understand and model the distribution of and the relation between baryonic and dark matter in the Universe is one of the key challenges in contemporary astrophysics. A well-established theoretical description is given ... -
The dense interstellar medium and star formation across the nearby galaxies NGC 3627 and NGC 253
Bešlić, Ivana (2023-10-11)The star formation process is an essential aspect of galaxy evolution. Observations of star-forming regions from sub-pc to kpc scales revealed a tight correlation between star formation and the emission of high-critical ... -
Environment and Properties of Submillimeter Galaxies
Aravena, Manuel (2009-03-06)Extra-galactic surveys with large submillimeter bolometer cameras discovered a population of dust obscured starbursting galaxies at high redshifts. These submillimeter galaxies (SMGs) are crucial in the stellar build up ... -
From star formation to regional distribution: Influences on the embedded cluster mass function
Lieberz, Patrick (2021-07-02)In this work we study the embedded cluster mass function (ECMF), meaning the mass distribution function of embedded clusters. Embedded clusters are fully or partially enclosed in interstellar gas, dust and molecular ... -
Grand-Design Warps in Galactic Disks
Józsa, Gyula István Géza (2006)Warping, a bending of the disk, is present in all disk galaxies. It is hence a phenomenon that should not be missed to be explained in theories of galactic evolution and formation. Warps usually occur at radii where the ... -
The Radio Continuum Halos of the Edge-on Galaxies NGC 891 and NGC 4565
Schmidt, Philip (2016-10-13)The halos of spiral galaxies are complex entities consisting of multiple matter components, generally including neutral and ionized gas phases, cosmic rays (CRs), dust, as well as extraplanar stars. The detection of ... -
Radio Continuum of Galaxies with H2O-Megamaser-Disks
Kamali, Fateme (2019-11-08)Galaxies with H<sub>2</sub>O-megamaser-disks are low luminosity active galaxies where 22GHz H<sub>2</sub>O-maser emission is detected in their accretion disk surrounding the central supermassive black hole (SMBH). Furthermore, ... -
Studying Galaxy-Galaxy Lensing and Higher-Order Galaxy-Mass Correlations Using the Halo Model
Rödiger, Jens (2009-06-22)In recent years, the distribution of galaxies in the Universe could be measured up to large distances and over a significant part of the sky. The analysis of this large-scale structure contains a wealth of cosmological ... -
Weak Lensing & Substructure
Pastor Mira, Emilio (2011-05-10)Understanding the evolution of the dark matter halos of galaxies after they become part of a cluster is essential for understanding their own evolution.<br /> This thesis is a feasibility study on applying galaxy-galaxy ...
