ALMA will determine the spectroscopic redshift z>8 with FIR [O III] emission lines
Akio K. Inoue, Ikkoh Shimizu, Yoichi Tamura +3
We investigate the potential use of nebular emission lines in the rest-frame far-infrared (FIR) for determining spectroscopic redshift of z>8 galaxies with the Atacama Large Millim…
The Effect of the Remnant Mass in Estimating Stellar Mass of Galaxies
Ikkoh Shimizu, Akio K. Inoue
The definition of the galactic stellar mass estimated from the spectral energy distribution is ambiguous in the literature; whether the stellar mass includes the mass of the stella…
Physical Properties of UDF12 Galaxies in Cosmological simulations
Ikkoh Shimizu, Akio K. Inoue, Takashi Okamoto +1
We have performed a large cosmological hydrodynamics simulation tailored to the deep survey with the Hubble Space Telescope made in 2012, the so-called UDF12 campaign. After making…
Non-hyperbolic automatic groups and groups acting on CAT(0) cube complex
Yoshiyuki Nakagawa, Makoto Tamura, Yasushi Yamashita
We discuss a problem posed by Gersten: Is every automatic group which does not contain Z+Z subgroup, hyperbolic? To study this question, we define the notion of "n-tracks of length…
Revealing the intricate effect of collaboration on innovation
Hiroyasu Inoue, Yang-Yu Liu
We study the Japan and U.S. patent records of several decades to demonstrate the effect of collaboration on innovation. We find that statistically inventor teams slightly outperfor…
The spectral evolution of the first galaxies. II. Spectral signatures of Lyman continuum leakage from galaxies in the reionization epoch
E. Zackrisson, A. K. Inoue, H. Jensen
The fraction of ionizing photons (fesc) that escape from z>6 galaxies is an important parameter when assessing the role of these objects in the reionization of the Universe, but th…
