Final results for mapping the Milky Way's stellar halo with blue horizontal-branch stars selected from the Subaru Hyper Supreme-Cam Survey
Tetsuya Fukushima, Masashi Chiba, Mikito Tanaka +7
We select blue-horizontal branch stars (BHBs) from the internal data release of the Hyper Suprime-Cam Subaru Strategic Program to reveal the global structure of the Milky Way (MW)…
Uncovering the Ghostly Remains of an Extremely Diffuse Satellite in the Remote Halo of NGC 253
Sakurako Okamoto, Annette M. N. Ferguson, Nobuo Arimoto +12
We present the discovery of NGC253-SNFC-dw1, a new satellite galaxy in the remote stellar halo of the Sculptor Group spiral, NGC 253. The system was revealed using deep resolved st…
Luminosity Functions of the Host Galaxies of Supernova
Zhuoxi Liang, Nao Suzuki, Mamoru Doi +2
We present the luminosity functions and stellar mass functions of supernova (SN) host galaxies and test if they differ from the functions of normal field galaxies. We utilize homog…
The structure of the stellar halo of the Andromeda galaxy explored with the NB515 for Subaru/HSC. I.: New Insights on the stellar halo up to 120 kpc
Itsuki Ogami, Mikito Tanaka, Yutaka Komiyama +16
We analyse the M31 halo and its substructure within a projected radius of 120 kpc using a combination of Subaru/HSC and CFHT/MegaCam - \& -…
