A Naked Dwarf: Molecular Gas in the Completely Stripped H i Tail of VCC 1249

Bumhyun Lee, Aeree Chung, P. Serra, Nikki Zabel et autres

Abstract We present the first observational hints of the severe removal of both molecular and H i gas from the dwarf galaxy VCC 1249. This extreme stripping event is thought to be driven by the combined effects of tidal interaction and ram …

Insights into Jet-induced Cloud Disruption in NGC 1316: ALMA Reveals Spatially Extended Molecular Gas

Kana Morokuma-Matsui, Alexander Y. Wagner, F. M. Maccagni, Lauranne Lanz et autres

Abstract We present Atacama Large Millimeter/submillimeter Array (ALMA) CO( J = 1−0) observations of a nearby radio galaxy, NGC 1316, at 100 pc resolution to investigate the impact of active galactic nucleus (AGN) jets on the molecular gas. The molecular gas exhibits …

Molecular Gas Structure and Star Formation Diversity in Stephan’s Quintet Revealed by ACA CO(1–0) Mapping

Misaki Yamamoto, Fumiya Maeda, Kazuyuki Muraoka, Fumi Egusa et autres

Abstract We present 12 CO(1–0) mapping across the entire system of Stephan’s Quintet, a well-known compact galaxy group, observed by Atacama Compact Array (7 m array + Total Power) of the Atacama Large Millimeter/submillimeter Array. These observations provide the first large-scale (137 …

Insights into Jet-Induced Cloud Disruption in NGC 1316: ALMA Reveals a Spatially Extended Molecular Gas

Kana Morokuma-Matsui, Alexander Y. Wagner, F. M. Maccagni, Lauranne Lanz et autres

We present ALMA CO($J=1-0$) observations of a nearby radio galaxy NGC1316 at a 100-pc resolution to investigate the impact of AGN jets on the molecular gas. The molecular gas exhibits complex spatial and kinematic distributions, with broad CO line widths ($>50$ km …

Upper Limit on HF(1–0) Absorption in a Dusty Star-forming Galaxy at z = 6: Constraints on Early Fluorine Enrichment

Akiyoshi Tsujita, Chiaki Kobayashi, Yuki Yoshimura, Kotaro Kohno et autres

Abstract Wolf–Rayet (WR) stars have recently attracted attention as possible drivers of early chemical enrichment, including the production of fluorine, whose nucleosynthetic origin remains debated. To test the contribution of massive stars to fluorine production in the early Universe, we conducted Atacama …
