UVIT view of NGC 5291: Ongoing star formation in tidal dwarf galaxies at ~ 0.35 kpc resolution
Rakhi R, Geethika Santhosh, Prajwel Joseph +14
NGC 5291, an early-type galaxy surrounded by a giant HI ring, is believed to be formed from collision with another galaxy. Several star forming complexes and tidal dwarf galaxies a…
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…
Ultraviolet imaging observations of three jellyfish galaxies: Star formation suppression in the centre and ongoing star formation in stripped tails
Koshy George, B. M. Poggianti, Neven Tomičić +13
Spiral galaxies undergo strong ram-pressure effects when they fall into the galaxy cluster potential. As a consequence, their gas is stripped to form extended tails within which st…
Investigating star-formation activity towards the southern HII region RCW 42
Vipin Kumar, S. Vig, V. S. Veena +4
The star-forming activity in the HII region RCW 42 is investigated using multiple wavebands, from near-infrared to radio wavelengths. Located at a distance of 5.8 kpc, this souther…
Stellar populations of the globular cluster NGC 5053 investigated using AstroSat-Ultra Violet Imaging Telescope
K. J. Nikitha, S. Vig, S. K. Ghosh
Globular clusters being old and densely packed serve as ideal laboratories to test stellar evolution theories. Although there is enormous literature on globular clusters in optical…
Host galaxy magnitude of OJ 287 from its colours at minimum light
Mauri J. Valtonen, Lankeswar Dey, S. Zola +54
OJ 287 is a BL Lacertae type quasar in which the active galactic nucleus (AGN) outshines the host galaxy by an order of magnitude. The only exception to this may be at minimum ligh…
