Probing Infrared eXcess to Investigate Early-Universe Dust (PIXIEDust)

Tom J. L. C. Bakx, Hiddo S. B. Algera, Jean-Baptiste Jolly +25

Despite the implied presence of dust through reddened UV emission in high-redshift galaxies, no dust emission has been detected in the (sub)millimetre regime beyond . This…

The LMT 2 millimeter receiver system (B4R). II. Science demonstration observations toward Orion-KL/OMC-1

Teppei Yonetsu, Ryohei Kawabe, Yuki Yoshimura +26

We present the results of mapping and single-point spectral scans toward Orion-KL/OMC-1 performed as science demonstrations of a 2 mm SIS receiver, the Band 4 Receiver (B4R), insta…

The LMT 2 Millimeter Receiver System (B4R). I. Overview and Results of Science Demonstration

Ryohei Kawabe, Takeshi Sakai, Kunihiko Tanaka +30

We report on the results of the on-sky test and science demonstration conducted with the 2 mm receiver system, B4R, on the 50 m Large Millimeter Telescope (LMT), located at an alti…

Large gas inflow driven by a matured galactic bar in the early Universe

Shuo Huang, Ryohei Kawabe, Hideki Umehata +3

Bar structures are present in about half of local disk galaxies and play pivotal roles in secular galaxy evolution. Bars impose a non-axisymmetric perturbation to the rotating disk…

RIOJA. The dusty outflows and density-complex interstellar medium in the N-enhanced lensed galaxy RXCJ2248-ID at z=6.1

A. Crespo Gómez, Y. Tamura, L. Colina +19

We present an analysis on the kinematics and physical properties of the ionized gas in the lensed galaxy RXCJ2248-ID at z=6.1 based on high-resolution JWST NIRSpec/IFU data in comb…

A warm ultra-luminous infrared galaxy just 600 million years after the Big Bang

T. J. L. C. Bakx, Laura Sommovigo, Yoichi Tamura +24

We present an Atacama Large Millimeter/submillimeter Array (ALMA) Band 9 continuum detection () of MACS0416_Y1 that confirms the suspected warm dust (91 K) of…

ELPIS: Accelerated metal and dust enrichment in a proto-cluster core at

Hideki Umehata, Yoichi Tamura, Yoshinobu Fudamoto +17

We present a study of the metal, dust, and molecular gas content in galaxies within the A2744-z7p9OD proto-cluster at z ~ 7.88. We focus on two galaxy groups, the Quintet and the C…

Early massive galaxy formation in the core of a galaxy protocluster 650 million years after the Big Bang

Yoshinobu Fudamoto, Yurina Nakazato, Daniel Ceverino +24

Rest-frame optical observations with the James Webb Space Telescope (JWST) have uncovered a population of massive galaxies, exceeding solar masses, present less than a bi…

Compact Ionized Gas Region Surrounded by Porous Neutral Gas in a Dusty Lyman Break Galaxy at Redshift

Masato Hagimoto, Yoichi Tamura, Akio K. Inoue +9

Porous interstellar medium (ISM) structure in galaxies at the epoch of reionization (EoR) gives us a hint to understand what types of galaxies contribute to reionization. Although…
