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…

Formation of Substructure in Luminous Submillimeter Galaxies (FOSSILS): Evidence of Multiple Pathways to Trigger Starbursts in Luminous Submillimeter Galaxies

Ryota Ikeda, Daisuke Iono, Ken-ichi Tadaki +19

We present an analysis of rest-frame optical and far-infrared continuum emission in three luminous submillimeter galaxies (SMGs) at . The SMGs are spatial…

ALMA Deep Field in SSA22: Reconstructed [CII] Luminosity Function at z = 6

Natsuki H. Hayatsu, Rob J. Ivison, Paola Andreani +19

The ADF22 line survey reported detections of two high- line-emitting source candidates above 6-, both of which were shown to be spurious after follow-up observations. We inv…

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…

ADF22-WEB: A giant barred spiral starburst galaxy in the z = 3.1 SSA22 protocluster core

H. Umehata, C. C. Steidel, I. Smail +15

In the present-day universe, the most massive galaxies are ellipticals located in the cores of galaxy clusters, harboring the heaviest super-massive black holes (SMBHs). However th…

Large molecular and dust reservoir of a gravitationally-lensed submillimeter galaxy behind the Lupus-I molecular cloud

Yoichi Tamura, Akio Taniguchi, Tom J. L. C. Bakx +14

We report the Australian Telescope Compact Array and Nobeyama 45 m telescope detection of a remarkably bright = 44 mJy) submillimeter galaxy MM J154506.4-344318…
