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…

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…

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…

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(…

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…
