ALMA reveals Strong [CII] emission in a galaxy embedded in a giant Lyman-alpha blob at z=3.1

Hideki Umehata, Yuichi Matsuda, Yoichi Tamura +21

We report the result from observations conducted with the Atacama Large Millimeter/submillimeter Array (ALMA) to detect [CII] 158 um fine structure line emission from galaxies embe…

Clumpy and Extended Starbursts in the Brightest Unlensed Submillimeter Galaxies

Daisuke Iono, Min S. Yun, Itziar Aretxaga +16

The central structure in three of the brightest unlensed z=3-4 submillimeter galaxies are investigated through 0.015" - 0.05" (120 -- 360~pc) 860 micron continuum images obtained u…

The Sunyaev-Zel'dovich Effect at Five Arc-seconds: RXJ1347.5-1145 Imaged by ALMA

T. Kitayama, S. Ueda, S. Takakuwa +12

We present the first image of the thermal Sunyaev-Zel'dovich effect (SZE) obtained by the Atacama Large Millimeter/submillimeter Array (ALMA). Combining 7-m and 12-m arrays in Band…

SXDF-ALMA 2 Arcmin^2 Deep Survey: Resolving and Characterizing the Infrared Extragalactic Background Light Down to 0.5 mJy

Yuki Yamaguchi, Yoichi Tamura, Kotaro Kohno +22

We present a multi-wavelength analysis of five submillimeter sources (S_1.1mm = 0.54-2.02 mJy) that were detected during our 1.1-mm-deep continuum survey in the SXDF-UDS-CANDELS fi…

Do Circumnuclear Dense Gas Disks Drive Mass Accretion onto Supermassive Black Holes?

Takuma Izumi, Nozomu Kawakatu, Kotaro Kohno

We present a positive correlation between the mass of dense molecular gas () of pc scale circumnuclear disks (CNDs) and the black hole mass accretion rate…

ALMA observations of the submillimetre hydrogen recombination line from the type 2 active nucleus of NGC 1068

Takuma Izumi, Kouichiro Nakanishi, Masatoshi Imanishi +1

Hydrogen recombination lines at the submillimetre band (submm-RLs) can serve as probes of ionized gas without dust extinction. One therefore expects to probe the broad line region…

High resolution ALMA observations of dense molecular medium in the central regions of active galaxies

Kotaro Kohno, Ryo Ando, Akio Taniguchi +2

In the central regions of active galaxies, dense molecular medium are exposed to various types of radiation and energy injections, such as UV, X-ray, cosmic ray, and shock dissipat…
