The 2014 ALMA Long Baseline Campaign: First Results from High Angular Resolution Observations toward the HL TAU Region
We present Atacama Large Millimeter/submillimeter Array (ALMA) observations from the 2014 Long Baseline Campaign in dust continuum and spectral line emission from the HL Tau region. The continuum
HARP/ACSIS: a submillimetre spectral imaging system on the James Clerk Maxwell Telescope
This paper describes a new Heterodyne Array Receiver Programme (HARP) and AutoCorrelation Spectral Imaging System (ACSIS) that have recently been installed and commissioned on the James Clerk Maxwell
The Arcminute Microkelvin Imager
The Arcminute Microkelvin Imager is a pair of interferometer arrays operating with six frequency channels spanning 13.9–18.2 GHz, for observations on angular scales of 30 arcsec–10 arcmin and for
Constraints on the HL Tauri Protostellar Disk from Millimeter- and Submillimeter-Wave Interferometry
Millimeter and submillimeter interferometry is used to probe the dusty accretion disks around young protostars. New 460 GHz (λ = 650 μm) data from the Caltech Submillimeter Observatory and the James
High-Frequency Measurements of the Spectrum of Sagittarius A*
We report near-simultaneous interferometric measurements of the spectrum of Sagittarius A* over the 5-354 GHz range and single-dish observations that have yielded the first detection of Sgr A* at 850
THE 2014 ALMA LONG BASELINE CAMPAIGN: AN OVERVIEW*
A major goal of the Atacama Large Millimeter/submillimeter Array (ALMA) is to make accurate images with resolutions of tens of milliarcseconds, which at submillimeter (submm) wavelengths requires
HARP: a submillimetre heterodyne array receiver operating on the James Clerk Maxwell Telescope
This paper describes the key design features and performance of HARP, an innovative heterodyne focal-plane array receiver designed and built to operate in the submillimetre on the James Clerk Maxwell
ALMA Long Baseline Observations of the Strongly Lensed Submillimeter Galaxy HATLAS J090311.6+003906 at z=3.042
We present initial results of very high resolution Atacama Large Millimeter/submillimeter Array (ALMA) observations of the $z$=3.042 gravitationally lensed galaxy HATLAS J090311.6+003906 (SDP.81).
