UVIT observations of the Small Magellanic Cloud: Point source catalogue
Ashish Devaraj, Prajwel Joseph, C. S. Stalin +2
Three fields in the outskirts of the Small Magellanic Cloud were observed by the Ultra-Violet Imaging Telescope (UVIT) on board AstroSat, during 31 December 2017 and 01 January 201…
Smallest scale clumpy star formation in Stephan's Quintet revealed from UV and IR imaging
Prajwel Joseph, Koshy George, Smitha Subramanian +2
The spatial distribution and physical sizes of star forming clumps at the smallest scales provide valuable information on hierarchical star formation (SF). In this context, we repo…
More insights into bar quenching. Multi-wavelength analysis of four barred galaxies
Koshy George, P. Joseph, C. Mondal +3
The underlying nature of the process of star formation quenching in the central regions of barred disc galaxies that is due to the action of stellar bar is not fully understood. We…
Insights on bar quenching from a multi-wavelength analysis: The case of Messier 95
Koshy George, P. Joseph, C. Mondal +3
The physical processes related to the effect of bar in the quenching of star formation in the region between the nuclear/central sub-kpc region and the ends of the bar (bar-region)…
Long term Ultra-Violet Variability of Seyfert galaxies
N. Sukanya, C. S. Stalin, P. Joseph +3
Flux variability is one of the defining characteristics of Seyfert galaxies, a class of active galactic nuclei (AGN). Though these variations are observed over a wide range of wave…
Ultra-Violet Imaging Telescope Observations of the Star-Forming Ring in NGC7252: Evidence of Possible AGN Feedback Suppressing Central Star Formation
Koshy George, P. Joseph, C. Mondal +11
Some post-merger galaxies are known to undergo a starburst phase that quickly depletes the gas reservoir and turns it into a red-sequence galaxy, though the details are still uncle…
Dissecting star-formation in the "Atoms-for-Peace" galaxy: Ultra-Violet Imaging Telescope observations of the post-merger galaxy NGC7252
Koshy George, P. Joseph, P. Côté +9
The tidal tails of post-merger galaxies exhibit ongoing star formation far from their disks. The study of such systems can be useful for our understanding of gas condensation in di…
