Cosmic star formation history revealed by the AKARI, & Spatially-resolved spectroscopy of an E+A (Post-starburst) system
Tomotsugu Goto, the AKARI NEPD team, M. Yagi +1
We reveal cosmic star-formation history obscured by dust using deep infrared observation with the AKARI. A continuous filter coverage in the mid-IR wavelength (2.4, 3.2, 4.1, 7, 9,…
Environmental dependence of 8um luminosity functions of galaxies at z~0.8: Comparison between RXJ1716.4+6708 and the AKARI NEP deep field
Tomotsugu Goto, Yusei Koyama, T. Wada +20
We aim to reveal environmental dependence of infrared luminosity functions (IR LFs) of galaxies at z~0.8 using the AKARI satellite. We construct restframe 8um IR LFs in the cluster…
A QSO host galaxy and its Lyalpha emission at z=6.43
Tomotsugu Goto, Yousuke Utsumi, Hisanori Furusawa +2
We report an optical detection of an extended structure around a QSO at z=6.43 (CFHQSJ2329-0301, the highest redshift QSO currently known) in deep z' and z_r-band images of the Sub…
The Mid-infrared View of Red Sequence Galaxies in Abell 2218 with AKARI
Jongwan Ko, Myungshin Im, Hyung Mok Lee +16
We present the {\it AKARI} InfraRed Camera (IRC) imaging observation of early-type galaxies in A2218 at z 0.175. Mid-infrared (MIR) emission from early-type galaxies trace…
