Final Results of Search for New Milky Way Satellites in the Hyper Suprime-Cam Subaru Strategic Program Survey: Discovery of Two More Candidates
Daisuke Homma, Masashi Chiba, Yutaka Komiyama +11
We present the final results of our search for new Milky Way (MW) satellites using the data from the Hyper Suprime-Cam (HSC) Subaru Strategic Program (SSP) survey over …
Transition probabilities of near-infrared Ce III lines from stellar spectra: applications to kilonovae
Nanae Domoto, Jae-Joon Lee, Masaomi Tanaka +6
Kilonova spectra provide us with information of r-process nucleosynthesis in neutron star mergers. However, it is still challenging to identify individual elements in the spectra m…
Cerium features in kilonova near-infrared spectra: implication from a chemically peculiar star
Masaomi Tanaka, Nanae Domoto, Wako Aoki +14
Observations of the kilonova from a neutron star merger event GW170817 opened a way to directly study r-process nucleosynthesis by neutron star mergers. It is, however, challenging…
EMPRESS. XIII. Chemical Enrichments of Young Galaxies Near and Far at z ~ 0 and 4-10: Fe/O, Ar/O, S/O, and N/O Measurements with Chemical Evolution Model Comparisons
Kuria Watanabe, Masami Ouchi, Kimihiko Nakajima +14
We present gas-phase elemental abundance ratios of 7 local extremely metal-poor galaxies (EMPGs) including our new Keck/LRIS spectroscopy determinations together with 33 JWST $z\si…
Machine learning detects multiplicity of the first stars in stellar archaeology data
Tilman Hartwig, Miho N. Ishigaki, Chiaki Kobayashi +2
In unveiling the nature of the first stars, the main astronomical clue is the elemental compositions of the second generation of stars, observed as extremely metal-poor (EMP) stars…
