Upper limit on HF(1-0) absorption in a dusty star-forming galaxy at : Constraints on early fluorine enrichment
Akiyoshi Tsujita, Chiaki Kobayashi, Yuki Yoshimura +10
Wolf-Rayet (WR) stars have recently attracted attention as possible drivers of early chemical enrichment, including the production of fluorine, whose nucleosynthetic origin remains…
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…
Unveiling Stellar Feedback and Cloud Structure in the Ophiuchi A Region with ALMA and JWST: Discovery of Substellar Cores, CO Striations, and Protostellar Outflows
Fumitaka Nakamura, Ryohei Kawabe, Shuo Huang +9
In clustered star-forming regions, stellar feedback-such as HII regions/photon-dominated regions (PDRs), and protostellar jets/outflows-shapes cloud structures and influences star…
ADF22+: a declining faint end in the far-infrared luminosity function in the SSA22 protocluster at z=3.09
Shuo Huang, Hideki Umehata, Ian Smail +6
Protoclusters represent the densest regions of cosmic large-scale structure in the early universe and are the environment where present-day massive elliptical galaxies are assemble…
ALMA Lensing Cluster Survey: Physical characterization of near-infrared-dark intrinsically faint ALMA sources at z=2-4
Akiyoshi Tsujita, Kotaro Kohno, Shuo Huang +33
We present results from Atacama Large Millimeter/submillimeter Array (ALMA) spectral line-scan observations at 3-mm and 2-mm bands of three near-infrared-dark (NIR-dark) galaxies b…
