A Naked Dwarf: Molecular Gas in the Completely Stripped HI Tail of VCC 1249
Bumhyun Lee, Aeree Chung, Paolo Serra +12
We present the first observational hints of the severe removal of both molecular and HI gas from the dwarf galaxy VCC 1249. This extreme stripping event is thought to be driven by…
An AGN in the Antennae galaxies ?
Shinya Komugi, Toshiki Saito, Tomonari Michiyama +5
Time variability is a strong probe of energetic phenomena which occur at small spatial scales, like Active Galactic Nuclei (AGN). We use ALMA observations at 100 GHz executed over…
Cloud-Cloud Collisions Induce Filament-Mediated Super Star Cluster Formation in the Antennae Overlap Region: Evidence from ALMA and JWST
Tomonari Michiyama, Toshiki Saito, Kouichiro Nakanishi +5
The formation of super star clusters (SSCs) in galaxies remains a fundamental yet unresolved problem. Among the proposed mechanisms, cloud-cloud collisions (CCCs) have been suggest…
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…
From Non-Detection to Detection: Atacama Compact Array Mosaic Observations of Faint Extended [C I] Emission in NGC 7679
Tomonari Michiyama, Toshiki Saito, Kouichiro Nakanishi +8
We report the detection of [C I] -- emission in the nearby galaxy NGC 7679 using the Atacama Compact Array (ACA) of the Atacama Large Millimeter/submillimeter Array (…
Warm Gas in the Vicinity of a Supermassive Black hole 13 Billion Years Ago
Ken-ichi Tadaki, Federico Esposito, Livia Vallini +4
Quasars, powered by supermassive black holes (SMBH), are among the brightest objects in the universe. In the vicinity of an SMBH, X-ray photons from an active galactic nucleus (AGN…
