A systematic comparison of green valley selection criteria across multiparameter spaces using a homogeneous ultraviolet-optical dataset
Pius Privatus, Umananda Dev Goswami
We present a systematic comparison of commonly adopted green valley (GV) selection criteria by examining their distributions across multiple observational and physical parameter sp…
What's Missing in AGN Feedback? Lessons learnt from Magneticum, IllustrisTNG and Simba
D. T. Mazengo, P. Popesso, I. Marini +20
Accurately balancing gas reservoirs, star formation, and feedback across cosmic time remains a central challenge for galaxy formation models in modern hydrodynamical simulations. W…
Analysis of the Effect of Bars on Environmental Dependence of Disc Galaxies with MaNGA Survey Data
Pius Privatus, Umananda Dev Goswami
Bars are fundamental structures in disc galaxies, although their role in galaxy evolution is still not fully known. This study investigates the effect of the presence of bars on th…
Galaxy Evolution in the Local Universe: Group Richness Effects on Mergers and Non-Mergers
Pius Privatus, Umananda Dev Goswami
In this study, we use the luminous volume-limited samples obtained from the twelfth release of Sloan Digital Sky Survey data and mergers from Galaxy Zoo Project to investigate the…
Mapping Nearby Galaxies with Apache Point Observatory: Group and field galaxies' morphologies in the colour-magnitude plane
Pius Privatus, Umananda Dev Goswami
This study involves the use of integral field spectroscopy (IFS) data from Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) to investigate whether the morphology influen…
Isolated and group environment dependence of stellar mass and different star formation rates
Pius Privatus, Umananda Dev Goswami
In this study, we explored the impact of isolated and group environments on stellar mass, star formation rate (SFR), and specific star formation rate (SSFR, i.e., the rate of star…
