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 continuumExpand
DISCOVERY OF THE METHOXY RADICAL, CH3O, TOWARD B1: DUST GRAIN AND GAS-PHASE CHEMISTRY IN COLD DARK CLOUDS*
We report on the discovery of the methoxy radical (CH3O) toward the cold and dense core B1-b based on the observation, with the IRAM 30 m radio telescope, of several lines at 3 and 2 mm wavelengths.Expand
VELOCITY-RESOLVED [C ii] EMISSION AND [C ii]/FIR MAPPING ALONG ORION WITH HERSCHEL.
TLDR
It is concluded that the [C ii] emitting column relative to the total dust column along each line of sight is responsible for the observed L[C ii?]/LFIR variations through the cloud. Expand
Detection of 15NH2D in dense cores : a new tool for measuring the 14N/15N ratio in the cold ISM
Context. Ammonia is one of the most reliable tracers of cold dense cores. It is also a minor constituent of interstellar ices and, as such, one of the important nitrogen reservoirs in the protosolarExpand
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).Expand
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 requiresExpand
A line confusion limited millimeter survey of Orion KL
Aims. We present a study of the silicon-bearing species detected in a line-confusion limited survey towards Orion KL performed with the IRAM 30-m telescope. The analysis of the line survey isExpand
HERSCHEL OBSERVATIONS OF EXTRAORDINARY SOURCES: ANALYSIS OF THE HIFI 1.2 THz WIDE SPECTRAL SURVEY TOWARD ORION KL. I. METHODS ∗
We present a comprehensive analysis of a broadband spectral line survey of the Orion Kleinmann-Low nebula (Orion KL), one of the most chemically rich regions in the Galaxy, using the HIFI instrumentExpand
Tracing the Shock Precursors in the L1448-mm/IRS 3 Outflows
We present the detection of the SiO ν = 0, J = 2-1, and J = 3-2 lines and of the HCO 101-000, J = 3/2-1/2, F = 2-1 line at ambient velocities toward the molecular outflows in L1448-mm and L1448 IRSExpand
Molecular outflows towards O-type young stellar objects
Context. The formation of massive stars is not well-understood and requires detailed observational studies in order to discriminate between the different proposed star formation models. Aims. We haveExpand
