Tracing evolutionary pathways of bar-driven quenching in local Universe disc galaxies
D Renu, Smitha Subramanian, Koshy George
Bars play an integral role in regulating star formation (SF) in spiral galaxies, from triggering central starbursts to driving quenching. The diverse SF morphologies observed in lo…
Star formation outside galaxies undergoing gravitational and hydrodynamic interactions: Dust attenuation and the star formation rate
Geethika Santhosh, Rakhi R, Koshy George +3
Galaxies undergo perturbations, either gravitational or hydrodynamic in origin, which can generate extragalactic structures such as rings and tails, where in situ star formation ma…
Star formation in interacting galaxy systems: UVIT imaging of NGC 7252 and NGC 5291
Geethika Santhosh, Rakhi R, Koshy George +2
Interactions play a significant role in the formation and evolution of galaxies in the Universe. The galaxy systems, NGC 7252 and NGC 5291 are two nearby interacting systems that a…
Investigating the role of bars in quenching star formation using spatially resolved UV-optical colour maps
D. Renu, Smitha Subramanian, Suhasini Rao +1
Bars are ubiquitously found in disc galaxies and are known to drive galaxy evolution through secular processes. However, the specific contribution of bars in suppression of star fo…
