Discovery of a Broad-Line Active Galactic Nucleus at
Xingyao Cai, Akio K. Inoue, Masafusa Onoue +12
The James Webb Space Telescope (JWST) has uncovered a previously unexplored population of faint active galactic nuclei (AGNs) in the early Universe. We present MoM-BL-z10 at $z=9.9…
Diversity of Ionized Gas Structures in Nearby Metal-poor Dwarf Galaxies
Yuki Takagishi, Takuya Hashimoto, Kazuya Matsubayashi +13
We investigate whether optical and far-infrared [O III] emission from nearby metal-poor dwarf galaxies can be represented by a homogeneous one-zone ionized-gas model with a single…
RIOJA. Environmental Effects on Stellar Populations and Ionized Gas in a Protocluster at
Wataru Osone, Takuya Hashimoto, Javier Álvarez-Márquez +23
Protoclusters in the epoch of reionization provide key laboratories for investigating how environment shapes early galaxy formation and evolution, and may also have contributed to…
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…
FINER: development of the wideband millimeter-wave receiver system and preparations for first light on the Large Millimeter Telescope
Akio Taniguchi, Yoichi Tamura, Takeshi Sakai +38
The recent discovery of an excess of luminous galaxies in the early Universe necessitates sensitive and wideband millimeter spectroscopy to understand their rapid growth. To addres…
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 discoveries of high-redshift QGs in overdensi…
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 sensit…
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) i…
