It is important to investigate the relationships between the power sources and the chemical compositions of galaxies for understanding the scenario of galaxy evolution. We carried…
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…
Unbiased large spectroscopic surveys of galaxies selected by SPICA using dust bands
H. Kaneda, D. Ishihara, S. Oyabu +27
The mid-infrared (IR) range contains many spectral features associated with large molecules and dust grains such as polycyclic aromatic hydrocarbons (PAHs) and silicates. These are…
Galaxy evolution studies with the SPace IR telescope for Cosmology and Astrophysics (SPICA): the power of IR spectroscopy
L. Spinoglio, A. Alonso-Herrero, L. Armus +65
IR spectroscopy in the range 12-230 micron with the SPace IR telescope for Cosmology and Astrophysics (SPICA) will reveal the physical processes that govern the formation and evolu…
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…
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 (…
Blind millimeter line emitter search using ALMA data toward gravitational lensing clusters
Yuki Yamaguchi, Kotaro Kohno, Yoichi Tamura +10
We present the results of a blind millimeter line emitter search using ALMA Band 6 data with a single frequency tuning toward four gravitational lensing clusters (RXJ1347.5-1145, A…
SCUBA-2 Ultra Deep Imaging EAO Survey (STUDIES): Faint-End Counts at 450 um
Wei-Hao Wang, Wei-Ching Lin, Chen-Fatt Lim +40
The SCUBA-2 Ultra Deep Imaging EAO Survey (STUDIES) is a three-year JCMT Large Program aiming at reaching the 450 m confusion limit in the COSMOS-CANDELS region, to study a repr…
Cold Molecular Gas Along the Merger Sequence in Local Luminous Infrared Galaxies
Takuji Yamashita, Shinya Komugi, Hideo Matsuhara +7
We present an initial result from the 12CO (J=1-0) survey of 79 galaxies in 62 local luminous and ultra-luminous infrared galaxy (LIRG and ULIRG) systems obtained using the 45 m te…
Disentangling the Circumnuclear Environs of Centaurus A: III. An Inner Molecular Ring, Nuclear Shocks and the CO to warm H2 interface
D. Espada, S. Matsushita, R. E. Miura +11
We present the distribution and kinematics of the molecular gas in the circumnuclear disk (CND, 400 pc x 200 pc) of Centaurus A with resolutions of ~5 pc (0.3 arcsec) and shed ligh…
