Stellar population and structural properties of dwarf galaxies and young stellar systems in the M81 group

28 Sep 2019 Okamoto Sakurako Arimoto Nobuo Ferguson Annette M. N. Irwin Mike J. Bernard Edouard J. Utsumi Yousuke

We use Hyper Suprime-Cam on the Subaru Telescope to investigate the structural and photometric properties of early-type dwarf galaxies and young stellar systems at the center of the M81 Group. We have mapped resolved stars to $\sim2$ magnitudes below the tip of the red giant branch over almost 6.5 square degrees, corresponding to a projected area of $160\times160 \rm{kpc}$ at the distance of M81...
