Constraining the Major Merging History of Massive Galaxies: A Comprehensive Analysis of Close Pairs and Tidal Features Using Empirical and Simulated Data
… the Hubble Space Telescope (HST) and realistic mock observations from leading theoretical simulations. We analyze the incidence of major, similar-mass (mass ratio<4) close pairs among a large sample of ~9800 massive galaxies (log Mstellar/Msun > 10.3) from the HST-CANDELS survey and quantify the …

Cosmology from galaxy clusters with cosmic microwave background lensing mass calibration
… the CMB lensing signal-to-noise, with mock observations from an N-body simulation. We then perform a joint likelihood analysis of the cluster counts and mass observables taking as input the CMB lensing signal-to-noise ratios, SZ signal-to-noise ratios, and redshifts. Our analysis uses a …

Correcting the rotation curve of spiral galaxies for the non-circular motions induced by a bar
… the kinematics and bar properties obtained from mocked galaxies. In chapter III, we examine the performance of ROTCUR and DISKFIT for deriving rotation curves from velocity maps of barred spiral galaxies using mock observations. Our results confirm that ROTCUR under-/overestimates measured …

Gas in Void Galaxies
… and systematically, using a combination of observations and simulations, to form a more complete understanding of the nature of these systems. We investigate in detail the H I morphology and kinematics of two void galaxies. One is an isolated polar disk galaxy in a diffuse cosmological wall …

Spatially resolved star formation and quenching: insights from observations and simulations
… epochs probed. In the second chapter, I use mock observations of galaxies from the EAGLE, Magneticum, and IllustrisTNG simulations to match MAGPI observational details including the average point spread function and pixel scale. Overall, there is no agreement in radial trends between MAGPI …

Connecting simulations and observations in galaxy formation studies
… provide, the connection between simulations and observations is still not fully established, although simulations are often used in galaxies' studies to interpret observations and assess the effect of the different processes acting on galaxies on the observable properties, and simulators usually …
