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…
Dust in Galaxies at : Attenuation and Re-emission Predictions from the FirstLight Simulations
Yurina Nakazato, Akio K. Inoue, Rachel S. Somerville +3
Dust masses and grain properties in galaxies remain poorly constrained, as JWST UV attenuation and ALMA dust re-emission are rarely modelled consistently. We perform post-pr…
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…
Breathing Fire: Hot Dust in the Big Three Dragons at z = 7.15
Gitanjali Rajulal, Hiddo S. B. Algera, Yuma Sugahara +25
We present new Atacama Large Millimeter/submillimeter Array (ALMA) Band 9 () and 4 () observations towards th…
GREX-PLUS Science Book v2
PLUS Science Team, Shunsuke Baba, Sirio Belli +52
GREX-PLUS (Galaxy Reionization EXplorer and PLanetary Universe Spectrometer) is a mission candidate for a JAXA strategic L-class mission to be launched in the 2030s. Its primary sc…
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…
JWST spectroscopy of galaxies at : Damped Ly absorbers reveal efficient star formation and hidden redshift biases
Kasper E. Heintz, Clara L. Pollock, Joris Witstok +23
Recent observations with JWST have revealed a remarkable population of surprisingly luminous galaxies at redshifts . Their abundance exceed predictions from simulations and e…
Suppression of star formation at the centre of barred AGN galaxies
Takashi Yamamoto, Nario Kuno, Daisuke Iono +5
We measured the Concentration (C) index of Hαand CO (J = 2-1) in 17 nearby star-forming galaxies from the PHANGS survey. We have found four barred spiral galaxies with a C(Hα)/C(CO…
Assessing the Impact of Source Confusion for GREX-PLUS based on Deep JWST NIRCam Imaging
Yoshiaki Ono, Akio K. Inoue, Yuma Sugahara +9
We investigate the effects of source confusion expected in observations with GREX-PLUS, a JAXA L-class space infrared telescope mission candidate with a wide-field infrared camera…
Characterising Ly damping wings at the onset of reionisation: Evidence for highly efficient star formation driven by dense, neutral gas in UV-bright galaxies at
Clara L. Pollock, Kasper E. Heintz, Joris Witstok +23
One of the major conundrums in contemporary extragalactic astrophysics is the apparent overabundance of a remarkable population of UV-bright galaxies at redshifts . We…
Clump-Scale Dust Attenuation in Epoch of Reionization Galaxies: Spatially Resolved Properties from FirstLight Simulations
Yurina Nakazato, Kosei Matsumoto, Akio K. Inoue +3
Understanding dust attenuation in galaxies at both integrated and spatially resolved scales is fundamental for accurately determining the physical properties of galaxies. Recent hi…
