Statistical Study of the Star Formation Efficiency in Bars: Is Star Formation Suppressed in Gas-Rich Bars?
Fumiya Maeda, Fumi Egusa, Kouji Ohta +2
The dependence of star formation efficiency (SFE) on galactic structures, especially whether the SFE in the bar region is lower than those in the other regions, has recently been d…
Optical IFU Observations of GOALS Sample with KOOLS-IFU on Seimei Telescope: Initial results of 9 U/LIRGs at 0.04
Yoshiki Toba, Satoshi Yamada, Kazuya Matsubayashi +23
We present ionized gas properties of 9 local ultra/luminous infrared galaxies (U/LIRGs) at 0.04 through IFU observations with KOOLS-IFU on Seimei Telescope. The observed targ…
Early Growth of the Star Formation Rate Function in the Epoch of Reionization: an Approach with Rest-frame Optical Emissions
Yoshihisa Asada, Kouji Ohta
We present a star formation rate function (SFRF) at based on star formation rates (SFRs) derived by spectral energy distribution (SED) fitting on data from rest-frame UV t…
CO(2-1)/CO(1-0) line ratio on 100 parsec scale in the nearby barred galaxy NGC1300
Fumiya Maeda, Fumi Egusa, Kouji Ohta +3
CO(2-1) emission is often used as a tracer of the giant molecular clouds (GMCs) as an alternative to CO(1-0) emission in recent years. Therefore, understanding the environmental de…
Search for H Emitters at : A Constraint on the H-based Star Formation Rate Density
Y. Asada, K. Ohta
We search for H emitters at in four gravitationally lensed fields observed in the Hubble Frontier Fields program. We use the Lyman break method to select galaxies at…
J-GEM optical and near-infrared follow-up of gravitational wave events during LIGO's and Virgo's third observing run
Mahito Sasada, Yousuke Utsumi, Ryosuke Itoh +68
The Laser Interferometer Gravitational-wave Observatory Scientific Collaboration and Virgo Collaboration (LVC) sent out 56 gravitational-wave (GW) notices during the third observin…
