The central region of the enigmatic Malin 1
  Malin 1, being a class of giant low surface galaxies, continues to surprise
us even today. The HST/F814W observation has shown that the central region of
Malin 1 is more like a normal SB0/a galaxy, while the rest of the disk has the
characteristic of a low surface brightness system. The AstroSat/UVIT
observations suggest scattered recent star formation activity all over the
disk, especially along the spiral arms. The central 9" ($\sim 14$ kpc) region,
similar to the size of the Milky Way's stellar disk, has a number of far-UV
clumps - indicating recent star-formation activity. The high resolution
UVIT/F154W image reveals far-UV emission within the bar region ($\sim 4$ kpc) -
suggesting the presence of hot, young stars in the bar. These young stars from
the bar region are perhaps responsible for producing the strong emission lines
such as H$\alpha$, [OII] seen in the SDSS spectra. Malin 1B, a dwarf early-type
galaxy, is interacting with the central region and probably responsible for
inducing the recent star-formation activity in this galaxy.
