Abstract:
We present Atacama Large Millimeter/submillimeter Array (ALMA) 870 µm
(345 GHz) data for 49 high-redshift (0.47<z<2.85), luminous
(11.7<log(Lbol/L☉)<14.2) radio-powerful active galactic nuclei
(AGNs), obtained to constrain cool dust emission from starbursts
concurrent with highly obscured radiative-mode black hole (BH)
accretion in massive galaxies that possess a small radio jet. The
sample was selected from the Wide-field Infrared Survey Explorer with
extremely steep (red) mid-infrared colors and with compact radio
emission from NVSS/FIRST. Twenty-six sources are detected at 870 µm,
and we find that the sample has large mid- to far-infrared luminosity
ratios, consistent with a dominant and highly obscured quasar. The
rest-frame 3 GHz radio powers are 24.7<log(P3.0GHz/W/Hz)<27.3
and all sources are radio-intermediate or radio-loud. BH mass estimates
are 7.7<log(MBH/M☉)<10.2. The rest-frame 1-5 µm spectral
energy distributions are very similar to the "Hot DOGs" (hot
dust-obscured galaxies), and steeper (redder) than almost any other
known extragalactic sources. ISM masses estimated for the
ALMA-detected sources are 9.9<log(MISM/M☉)<11.75 assuming
a dust temperature of 30 K. The cool dust emission is consistent with
star formation rates reaching several thousand M☉/yr, depending
on the assumed dust temperature, but we cannot rule out the
alternative that the AGN powers all the emission in some cases. Our
best constrained source has radiative transfer solutions with
approximately equal contributions from an obscured AGN and a young
(10-15 Myr) compact starburst.
Description:
Twenty-three sources were observed with ALMA in two Band 7 scheduling
blocks on 2011 November 16. An additional 14 were observed on 2012 May 25
and the final 12 on 2012 August 29. The central frequency was set to
345 GHz (870 µm), with an 8 GHz bandwidth split into two sidebands.
Fifteen antennas were used in the "compact" Early Science
configuration for the 2011 November observations, 19 for the 2012 May
observations, and 23 for the August observations. The resulting
beamsizes are 1.2", 0.5", and 1.2", respectively.
