Subaru/HSC NB395 view of NGC 5466: metallicity, mass function, and the nature of its tidal stream

Itsuki Ogami, Miho N. Ishigaki, Pete B. Kuzma +6

We present a deep photometric study of the globular cluster NGC 5466 and its tidal stream using Subaru/Hyper Suprime-Cam (HSC) imaging with the metallicity-sensitive narrowband fil…

A High Incidence of Mid-infrared Variability in Local Ultraluminous Infrared Galaxies

Shun Hatano, Masatoshi Imanishi, Takanobu Kirihara +3

We explore mid-infrared (MIR) variability in local ultraluminous infrared galaxies (ULIRGs; infrared luminsoity ) utilizing the 11 years of photo…

Constructing a Pristine View of Extended Globular Cluster Structure

Pete B. Kuzma, Miho N. Ishigaki, Takanobu Kirihara +1

Globular Clusters (GCs) displaying extended structures are becoming increasingly ubiquitous in the Milky Way (MW). Despite their low surface brightness, which makes disentangling t…

Tidal Debris Candidates from the Centauri Accretion Event and its Role in Building Up the Milky Way Halo

Borja Anguiano, Arik Mitschang, Takanobu Kirihara +11

We identify stellar tidal debris from the Centauri ( Cen) system among field stars in the APOGEE survey via chemical tagging using a neural network trained on APOGEE observa…

Simultaneous Formation of the Andromeda Giant Southern Stream and the Substructures in the Andromeda Halo

Misa Yamaguchi, Masao Mori, Takanobu Kirihara +4

We investigate a minor merger event in M31 that simultaneously forms the Andromeda Giant Southern Stream (AGSS), Eastern Extent (EE), North-Eastern Shelf (NES), and Western Shel (W…

Discrimination of heavy elements originating from Pop III stars in z = 3 intergalactic medium

Takanobu Kirihara, Kenji Hasegawa, Masayuki Umemura +2

We investigate the distribution of metals in the cosmological volume at , in particular, provided by massive population III (Pop III) stars using a cosmological -body si…
