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…
Constraint on the Gas-to-Dust Ratio in Massive Star-Forming Galaxies at z~1.4
Akifumi Seko, Kouji Ohta, Bunyo Hatsukade +3
We carried out 12CO(J=2-1) observations toward three star-forming galaxies on the main sequence at z~1.4 with the Nobeyama 45m radio telescope. These galaxies are detected with Spi…
