The dawn of the first galaxies
Livia Vallini, Tanio Diaz Santos, Belen Alcalde Pampliega +56
Understanding how the first galaxies assembled their stellar mass at cosmic dawn is a central frontier of modern astrophysics. JWST has now revealed an unexpected population of ult…
PRISMS. GHZ1. A standard tale of galaxy evolution with atypical ionizing conditions at
Borja Pérez-Díaz, Marco Castellano, Javier Álvarez-Márquez +33
[Abridged] The first operating years of the James Webb Space Telescope (JWST) have revealed a surprising number of UV-bright objects, many of them characterized by t…
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…
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…
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…
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…
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…
PRISMS. UNCOVER-26185, a metal-poor SFG at z=10.05 with no evidence for a X-ray-luminous AGN
J. Álvarez-Márquez, L. Colina, A. Crespo-Gomez +31
This work presents the first results of the PRImordial galaxy Survey with MIRI Spectroscopy (PRISMS), a JWST cycle 4 program (PID 8051) aimed at the characterization of a relativel…
PRISMS. U37126, a very blue, ISM-naked starburst at z=10.255 with nearly 100% Lyman continuum escape fraction
R. Marques-Chaves, J. Álvarez-Márquez, L. Colina +31
We present very deep (~11h) JWST/MIRI low-resolution spectroscopy of the rest-frame optical emission of U37126, a UV-bright (M_UV ~ -20), mildly lensed () galaxy at z=…
