Unveiling the Primary Quenching Mechanisms in Galaxies through Large Spectroscopic Surveys
Star-forming galaxies can be transformed into passive systems through a multitude of mechanisms that quench star formation, such as the halting of cold gas accretion (known as starvation) and the rapid removal of gas in AGN-driven winds. However, it remains unclear which mechanism is the most …

Studying the environmental dependence of star formation properties of galaxies in the Abell 1437 galaxy cluster and its surrounding large scale structure
… plays a crucial role in the evolution of galaxies. Recent studies show a strong bimodal distribution of galaxy properties, with red, passive galaxies dominating the bimodal distribution in dense environments, compared to blue, actively star forming galaxies dominating the bimodal …

Star formation and environment of galaxies
… the history of star formation. Stars form in galaxies, which are in essence huge aggregations of stars, dust and gas. Understanding star formation requires, among other things, measuring the rate at which interstellar gas is being converted into stars in a given galaxy. Star formation, a …

New Insights on the Evolutionary Mechanisms of Local and Distant Galaxies
Galaxies can be roughly characterised by falling into two distinct populations, blue, star-forming, disc dominated and red, quiescent elliptical bulge dominated systems. These populations are defined via multiple scaling relations such as the star-forming main sequence, Schmidt-Kennicutt relation …

LUMINOSITY DISTRIBUTIONS AND ABUNDANCE TOMOGRAPHY MODELLING OF TYPE IA SUPERNOVAE
… (MB <−18mag) SNeIa from star forming(S- F) and passive galaxies are distinct. This may indicate that various progenitor channels are prevalent in different galaxy types. Furthermore, it was also confirmed that sub- luminous SNe Ia tend to favour passive galaxies, which implies that this subset …

A Multiwavelength Analysis of the Effect of Cluster Environments on Galaxy Evolution
… is utilized as a comparative laboratory to galaxies that reside in the less dense field where it is ‘alone’. Within clusters, the buildup of red, passive galaxies is observed to be in excess of the field, yet the mechanisms responsible for this graveyard of galaxies remain to be clearly …

A Study on Quenching and Galaxy Growth in z~1 Clusters using HST WFC3 Grism Observations
… to study how the quenching of star formation in galaxies and galaxy size growth operates in different environments at this redshift. The unique capabilities of space-based slitless spectroscopy with the G141 grism allows for the construction of spatially resolved H$\alpha$ maps, providing the …
