Secondary evolution of galaxies investigated by N-body simulations [PDF]
In the ΛCDM cosmology, merging is one of the most important physical processes that drives the formation and evolution of galaxies. In the present work, we use N-body techniques to investigate some of currently open issues related to the formation and ...

Clustering and redshift-space distortions in QSO and galaxy surveys [PDF]
In this thesis, we exploit the potential of existing QSO and galaxy surveys for investigating the nature of the large scale structure in the Universe. A detailed analysis of clustering and redshift- space distortions allows us to constrain cosmological ...

The THESEUS Space Mission and the Infrared Telescope Calibration Unit
ABSTRACT The Transient High‐Energy Sky and Early Universe Surveyor (THESEUS) is an ESA M7 mission concept currently in Phase A, designed to exploit gamma‐ray bursts to probe the early Universe while advancing multi‐messenger and time‐domain astrophysics. To achieve its ambitious goals, THESEUS will combine wide‐band x‐ray and gamma‐ray monitors with an

Galaxy evolution as a function of mass and environment: giant and dwarf galaxies in superclusters and in the field [PDF]
It has been known for decades that local galaxies can be broadly divided into two distinct populations (e.g. Hubble 1926, 1936; Morgan 1958; de Vaucouleurs 1961).

ABSTRACT The goal of this study is to confirm the feasibility of the use of digitized low dispersive MtWilson Michigan Southern Sky Hα$$ \alpha $$ survey astronomical photographic plates for modern astrophysical research. The detection of highly redshifted objects, such as early galaxies and quasars, is fundamental to understanding the universe's ...

Spatially resolved spectroscopy of faint star-forming galaxies & their environments in the high redshift universe [PDF]
This thesis is concerned with the spectroscopic observations of distant galaxies, 1 < z < 5. The galaxies presented here are intrinsically faint such that their ux is dominated by ordinary star formation rather than galaxy-galaxy merging and/or ...

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory
ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

Lenticular galaxy formation: possible luminosity dependence [PDF]
We investigate the correlation between the bulge effective radius (re ) and disk scale length (rd ) in the near-infrared K band for lenticular galaxies in the field and in clusters.

Gravitational waves throughout galaxy evolution: stellar BH mergers and heavy SMBH seeds. [PDF]
The main goal of my thesis is to carefully characterize different astrophysical processes leading to gravitational wave (GW) emission, strongly relying on theoretical and observational astrophysical basis.
