The Kinematical Parameters of Minor Mergers and their Observational Traces
Parameters of Minor Mergers and their Observational Traces This work was motivated by observations that galaxies like our Milky Way are undergoing merger with galactic satellites and leaving behind observational traces. The thick disk of our Milky Way may be due to a collision with a satellite of …

A Study on Quenching and Galaxy Growth in z~1 Clusters using HST WFC3 Grism Observations
… to low redshifts. Many studies have argued that minor mergers are responsible for this size growth. To test this hypothesis, it is possible to use the cluster environment as a laboratory. Cluster galaxies have high peculiar velocities, making mergers between them rare. Since minor mergers are …

Investigating the Environmental Properties of Galaxies in the SDSS-MaNGA Survey
… core velocity dispersion to study the effects of minor mergers and tidal/ram pressure stripping, I find that central galaxies are up to 30% larger and more massive than satellites. I suggest that minor mergers play a crucial role in the increase in size and mass of centrals. In addition, I find …

Quenching mechanisms in recently quenched elliptical galaxies: insights from neutral hydrogen studies and environmental analysis
… rapid quenching, possibly initiated by major mergers, followed by brief AGN activity and sustained LINER emission. We propose two evolutionary pathways: (a) rapid quenching via major mergers followed by AGN/LINER activity and passive evolution, and (b) rapid quenching followed by rejuvenation …

Kinematics of neutral hydrogen in interacting galaxies in two groups from the MeerChoirs survey
… the impact of two ongoing co-rotating minor mergers, an intermediate-stage counter-rotating major merger, and an intermediate-stage co-rotating major merger. Additionally, we characterize several previously known and unknown dwarfs in the groups and the extended fields. We extract the …

The AGN-host galaxy connection : new insights from the extended ionised gas
… counterparts, which we interpret as evidence for minor mergers, supported by our detailed study of the bulge-dominated host of the luminous QSO HE 1029-1401, or smooth gas accretion from the environment. In this line another new discovery is that HE 2158-0107 at z=0.218 is the most metal poor …
