ALMA observations of pre-JWST z ~ 10 galaxy candidates: A CO(J = 9-8) line from a ULIRG at z = 2.54 and revisit of the photometric redshifts with JWST photometry
Suzuka Arai, Yuma Sugahara, Akio K. Inoue +15
We present Atacama Large Millimetre/submillimetre Array (ALMA) observations targeting the [OIII]m line for six galaxy candidates selected with the Hubble Space Tel…
Extremely UV-bright starbursts at the end of cosmic reionization
R. Marques-Chaves, D. Schaerer, M. Dessauges-Zavadsky +22
We present a study of 27 very UV-bright (-22.0<MUV<-24.4) sources at z~6 identified in SHELLQs survey. Stacking their rest-frame UV spectra reveals a prominent NV1240A P-Cygni, con…
The role of small-scale environments in the quenching of massive galaxies at
Takumi Kakimoto, Masayuki Tanaka, Makoto Ando +10
Massive quiescent galaxies (QGs) at high redshifts are likely progenitors of massive elliptical galaxies in the local Universe. Recent observations, such as the discovery of QGs in…
ATT12: The Antarctic 12-m Terahertz Telescope for Studies of Dusty Galaxies. I. Instrument Sensitivity and Science Forecasts
Koki Wakasugi, Takuya Hashimoto, Nario Kuno +13
We present a feasibility study of the Antarctic 12m Terahertz Telescope (ATT12), a next-generation facility to be constructed at New Dome Fuji in Antarctica, designed to open up th…
Deep Submillimeter and Radio Observations in the SSA22 Field. III. Multiwavelength Identifications and Properties of the 850 m-selected Submillimeter Galaxies
Xin Zeng, Yiping Ao, Zongfei Lyu +4
We present a multiwavelength analysis of 850 m-selected SMGs (deblended S 1mJy) in the SSA22 field, where our deepest JCMT/SCUBA-2 observations reach a sensi…
Deep Submillimeter and Radio Observations in the SSA22 Field. IV. Spectral Energy Distributions, Star Formation Histories, and the Infrared-Radio Correlation of the 850 m-selected SMGs
Xin Zeng, Yiping Ao, Ken Mawatari +1
We analyze the spectral energy distributions (SEDs), star formation histories (SFHs), and infrared-radio correlation (IRRC) of 221 850 m-selected submillimeter galaxies (SMGs)…
