Title: On The Outer Structure of the Magellanic Cloud Complex
Speaker: Abhijit Saha

Time: 11:00 - 12:00
Venue: SAAO Auditorium

Abstract

I will describe a deep imaging survey of selected regions in areas outlying the LMC and SMC, including the Magellanic Bridge and Magellanic Stream. We identify and use stars below the main sequence turn-off to delineate structures with effective surface brightness fainter than 33 mag per sq. arc sec. We are able to trace the disk of the LMC to 12 scale lengths, while failing to find a stellar halo. Our data are put in the context of the new paradigm that the Clouds are falling in to the Galaxy for the first time, and that structures such as the Magellanic Bridge and Stream have formed from the mutual interaction of the LMC and SMC alone.
