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
In-orbit performance of Herschel-HIFI
Aims. In this paper the calibration and in-orbit performance of the Heterodyne Instrument for the Far-Infrared (HIFI) is described. Methods. The calibration of HIFI is based on a combination of
The size, luminosity, and motion of the extreme carbon star IRC+10216 (CW Leonis)
Very Large Array observations of the extreme carbon star IRC+10216 at 7 mm wavelength with 40 milli-arcsec resolution resolve the object’s radio emission, which forms an almost round uniform disk of
An Interferometric Spectral Line and Imaging Survey of VY Canis Majoris in the 345 GHz Band
A spectral line survey of the oxygen-rich red supergiant VYCanis Majoris was made between 279 and 355GHz with the Submillimeter Array. Two hundred twenty three spectral features from 19 molecules
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
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).
V4332 Sagittarii: A circumstellar disc obscuring the main object
V4332 Sgr experienced an outburst in 1994 whose observational characteristics in many respects resemble those of the eruption of V838 Mon in 2002. It has been proposed that these objects erupted
OGLE-2002-BLG-360: from a gravitational microlensing candidate to an overlooked red transient
OGLE-2002-BLG-360 was discovered as a microlensing candidate by the OGLE-III project. The subsequent light curve however clearly showed that the brightening of the object could not have resulted from
Physical conditions of molecular gas in the Circinus galaxy Multi-J CO and C I P-3(1) -> P-3(0) observations
We report mapping observations of the (CO)-C-12 J = 3 -> 2, 4 -> 3, 6 -> 5, and 7 -> 6 transitions and the C I P-3(1) -> P-3(0) (C I) 492 GHz transition toward the central 40 '' x 40 '' region of the
Pure rotational spectra of TiO and TiO2 in VY Canis Majoris
We report the first detection of pure rotational transitions of TiO and TiO2 at (sub-)millimeter wavelengths towards the red supergiant VY CMa. A rotational temperature, Trot, of about 250 K was
