We exploit N-body simulations (GalactICS, Illustris, NIHAO) to study the impact of inclination on the estimates on various photometric and spectroscopic quantities of galaxies such as sizes, surface brightnesses, stellar ...

One of the most outstanding mysteries in the Universe is the nature of dark matter. In this thesis, two unique projects that focus on understanding dark matter are presented. First, Machine Learning is used to detect ...

The cause of varying galaxy interaction outcomes in different environments is investigated using a sample of over 505,000 Sloan Digital Sky Survey Data Release 7 galaxies at $0.01<z<0.20$. The aim is to distinguish the ...

In this thesis, we explore 7.5 billion years of evolution in cluster galaxy star formation activity using a sample of 11 high-redshift (1 < z < 1.5) clusters from the IRAC Shallow Cluster Survey, and 25 low-redshift (0.15 ...

By virtue of its proximity and richness, the Virgo galaxy cluster is a perfect testing ground to expand our understanding of structure formation in the Universe. Here, we present a comprehensive dynamical catalogue based ...

Rotation measure (RM) synthesis maps of NGC 4631 by Mora-Partiarroyo et al. (2018) show remarkable sign reversals on kpc scales as the distance from the minor axis increases in the northern halo of the galaxy. RM maps for ...

We have compiled a large sample of 3041 spiral galaxies with multi-band $gri$ photometry from the the Sloan Digital Sky Survey (SDSS) Data Release 7 archive. We compare our own extracted photometry with data products ...

In this thesis we present two projects investigating the evolution and quenching of cluster galaxy star formation (SF) activity. Leveraging a sample of 36 galaxy clusters, we measure the level of member SF activity. Over ...

Reconciling the velocity function of dark matter halos in collisionless simulations with those derived observationally requires understanding how galaxies are embedded in their dark matter halos. Widefield neutral atomic ...
