Imaging the Molecular Outflows of the Prototypical ULIRG NGC 6240 with ALMA
T. Saito, D. Iono, J. Ueda +12
We present 0".97 0".53 (470 pc 250 pc) resolution CO ( = 2-1) observations toward the nearby luminous merging galaxy NGC 6240 with the Atacama Large Millimeter…
Very compact millimeter sizes for composite star-forming/AGN submillimeter galaxies
Soh Ikarashi, Karina Caputi, Kouji Ohta +20
We report the study of far-IR sizes of submillimeter galaxies (SMGs) in relation to their dust-obscured star formation rate (SFR) and active galactic nuclei (AGN) presence, determi…
Diverse nuclear star-forming activities in the heart of NGC 253 resolved with ten-pc scale ALMA images
Ryo Ando, Kouichiro Nakanishi, Kotaro Kohno +13
We present an 8 pc x 5 pc resolution view of the central ~ 200 pc region of the nearby starburst galaxy NGC 253, based on ALMA Band 7 (λ ~ 0.85 mm or ν ~ 350 GHz) observations cove…
ALMA Multiple-Transition Molecular Line Observations of the Ultraluminous Infrared Galaxy IRAS 20551-4250: Different HCN, HCO+, HNC Excitation and Implications for Infrared Radiative Pumping
Masatoshi Imanishi, Kouichiro Nakanishi, Takuma Izumi
We present our ALMA multi-transition molecular line observational results for the ultraluminous infrared galaxy, IRAS 20551-4250, which is known to contain a luminous buried AGN an…
On the disappearance of a cold molecular torus around the low-luminosity active galactic nucleus of NGC 1097
T. Izumi, K. Kohno, K. Fathi +15
We used the Atacama Large Millimeter/submillimeter Array (ALMA) to map the CO(3-2) and the underlying continuum emissions around the type 1 low-luminosity active galactic nucleus (…
A radio-to-mm census of star-forming galaxies in protocluster 4C23.56 at z=2.5 : Gas mass and its fraction revealed with ALMA
Minju M. Lee, Ichi Tanaka, Ryohei Kawabe +18
We investigate gas contents of star-forming galaxies associated with protocluster 4C23.56 at z = 2.49 by using the redshifted CO(3-2) and 1.1 mm dust continuum with the Atacama Lar…
