| Details: | The study of morphology & dynamics of disk galaxies has drawn attention over several decades. This helps us in understanding the formation and evolution of disk galaxies across cosmic time. Several ongoing photometric & spectroscopic observations as well as high resolution cosmological, hydrodynamical simulations have made it possible to explore intriguing questions in this field. In this talk, I will try to discuss some of our explorations in the area of galaxy morphology focusing on the massive disk galaxies with extended low surface brightness stellar disk, present in the nearby universe. I will also briefly give an overview of our work on the vertical structure of the stellar disk in the Milky Way, especially in the light of Gaia observations. The upcoming observations from large surveys such as LSST (Legacy Survey of Space & Time), Euclid , 4MOST etc would open up unique opportunities to deal with several challenging questions in this field. |
