Classical and Pseudo Bulges : Clues to Galaxy Formation

Ajit Kembahavi (Pune University) Thursday, September 8th - 11am IPAG Seminar Room - IPAG

The bulges in galaxies have generally been considered to be very similar to elliptical galaxies, in their morphology, stellar content and origin. But it has been known that bulges in late type galaxies can be disk like and contain features such as spiral arms, bars and rings, which point to continued star formation. These pseudo-bulges are thought to be formed due to the transfer of gas to the central regions of galaxies through non-axisymmetric structures like bars. It is now known that such pseudo-bulges can also occur in early type galaxies like lenticulars. I will describe in my talk such pseudo-bulges and discuss the insights they provide into the development of the observed galaxy morphology.
