| Abstract : | The Small Magellanic Cloud (SMC) is one of the nearest gas-rich dwarf galaxies, which is in its first passage around the Milky Way (MW) Galaxy. Interacting with its companion, the Large Magellanic Cloud (LMC), and the MW Galaxy, the SMC experiences significant effects due to its much smaller dynamical mass compared to the LMC and the MW. The SMC shows active star formation and has non-homogeneous distribution of the young population, unlike the old population. The UV study of the SMC can lead to understanding the different recent interaction phenomena happening to the SMC. We used the images obtained using the Ultra Violet Imaging Telescope (UVIT) onboard AstroSat of the SMC main body and performed the PSF photometry on the science-ready images. We cross-matched the detected UV sources with Gaia DR3 data and created an FUV catalog of the most probable SMC UV stars aged up to a few Myr after 3 sigma clipping to parallax and proper motion. We plotted the density map and proper motion distribution of the SMC main body to understand the distribution and kinematics of the young populations due to the interaction. A significant discovery of our study is the detection of a young bar within the SMC main body, marking a noteworthy finding in our research. |
