Investigating the Young Stellar Populations and Hierarchies in Nearby Galaxies with the UVIT. III. Evidence for a Largest Scale of Correlated Stellar Structures and a Non-universal Fractal Dimension
Gairola Shashank, Smitha Subramanian, Shyam H. Menon +5
Scale-free turbulent motions, gravitational collapse and galactic dynamics govern galactic-scale, hierarchical organization of star formation (SF) within galaxies. Past studies sug…
Bar-driven gas redistribution suppresses star formation in spiral galaxies: Evidence from dust lanes in NGC 3351
Koshy George, Smitha Subramanian
We present observational evidence, based on high-resolution imaging from HST, ALMA, and AstroSat/UVIT, that the redistribution of gas driven by the bar in the face-on spiral galaxy…
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…
