Molecular Gas and Star Formation in Voids
M. Das, T. Saito, D. Iono +2
We present the detection of molecular gas using CO(1-0) line emission and follow up Halpha imaging observations of galaxies located in nearby voids. The CO(1-0) observations were d…
Compact starbursts in z~3-6 submillimeter galaxies revealed by ALMA
Soh Ikarashi, R. J. Ivison, Karina I. Caputi +17
We report the source size distribution, as measured by ALMA millimetric continuum imaging, of a sample of 13 AzTEC-selected submillimeter galaxies (SMGs) at z_photo ~ 3-6. Their in…
Properties of Molecular Gas in Galaxies in Early and Mid Stage of Interaction: II. Molecular Gas Fraction
Hiroyuki Kaneko, Nario Kuno, Daisuke Iono +4
We have investigated properties of the interstellar medium in interacting galaxies in early and mid-stage using mapping data of 12CO(1-0) and HI.Assuming the standard CO-H2 convers…
Around the Ring We Go: The Cold, Dense Ring of Molecular Gas in NGC 1614
Kazimierz Sliwa, Christine D. Wilson, Daisuke Iono +2
We present high-resolution archival Atacama Large Millimeter/submillimeter Array (ALMA) CO J=3-2 and J=6-5 and HCO+ J=4-3 observations and new CARMA CO and 13CO J=1-0 observations…
Cold Molecular Gas in Merger Remnants: I. Formation of Molecular Gas Disks
Junko Ueda, Daisuke Iono, Min S. Yun +11
We present < 1 kpc resolution CO imaging study of 37 optically-selected local merger remnants using new and archival interferometric maps obtained with ALMA, CARMA, SMA and PdBI. W…
Cluster Formation Triggered by Filament Collisions in Serpens South
Fumitaka Nakamura, Koji Sugitani, Tomohiro Tanaka +24
The Serpens South infrared dark cloud consists of several filamentary ridges, some of which fragment into dense clumps. On the basis of CCS (), HCN (), N$_2…
