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…

GLTCAM: Concept of Multi-color Millimeter and Submillimeter Camera for the Greenland Telescope

Shuhei Inoue, Tatsuya Takekoshi, Shinsuke Uno +12

To investigate the formation history of large-scale structure through the dynamics of galaxy clusters, we are developing a multi-color millimeter and submillimeter-wave continuum c…

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…
