The 2014 ALMA Long Baseline Campaign: First Results from High Angular Resolution Observations toward the HL TAU Region
- A. Partnership, C. Brogan, K. Tatematsu
- Physics, Geology
- 14 July 2015
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…

Constraints on the HL Tauri Protostellar Disk from Millimeter- and Submillimeter-Wave Interferometry
- O. Lay, J. Carlstrom, R. Hills
- Physics, Geology
- 10 November 1997
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*
- E. Serabyn, J. Carlstrom, R. Hills
- Physics
- 27 October 1997
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. Partnership, E. Fomalont, S. Wood
- Physics, Environmental Science
- 14 July 2015
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…
