Constraints on changes in the proton-electron mass ratio using methanol lines
N. Kanekar, W. Ubachs, K. M. Menten +6
We report Karl G. Jansky Very Large Array (VLA) absorption spectroscopy in four methanol (CHOH) lines in the gravitational lens towards PKS1830-211. Three of the…
ALMA Observations of Anisotropic Dust Mass-loss in the Inner Circumstellar Environment of the Red Supergiant VY Canis Majoris
E. O'Gorman, W. Vlemmings, A. M. S. Richards +8
The processes leading to dust formation and the subsequent role it plays in driving mass loss in cool evolved stars is an area of intense study. Here we present high resolution ALM…
ALMA sub-mm maser and dust distribution of VY Canis Majoris
A. M. S. Richards, C. M. V. Impellizzeri, E. M. Humphreys +25
Cool, evolved stars have copious, enriched winds. The structure of these winds and the way they are accelerated is not well known. We need to improve our understanding by studying…
Molecular line emission in NGC1068 imaged with ALMA: II. The chemistry of the dense molecular gas
S. Viti, S. García-Burillo, A. Fuente +19
We present a detailed analysis of ALMA Bands 7 and 9 data of CO, HCO+, HCN and CS, augmented with Plateau de Bure Interferometer (PdBI) data of the ~ 200 pc circumnuclear disk (CND…
Detection of chloronium and measurement of the 35Cl/37Cl isotopic ratio at z=0.89 toward PKS1830-211
S. Muller, J. H. Black, M. Guelin +11
We report the first extragalactic detection of chloronium (H2Cl+), in the z=0.89 absorber in front of the lensed blazar PKS1830-211. The ion is detected through its 1_11-0_00 line…
An ALMA Early Science survey of molecular absorption lines toward PKS1830-211 -- Analysis of the absorption profiles
S. Muller, F. Combes, M. Guelin +17
We present the first results of an ALMA spectral survey of strong absorption lines for common interstellar species in the z=0.89 molecular absorber toward the lensed blazar PKS1830…
UVMULTIFIT: A versatile tool for fitting astronomical radio interferometric data
I. Marti-Vidal, W. H. T. Vlemmings, S. Muller +1
The analysis of astronomical interferometric data is often performed on the images obtained after deconvolution of the interferometer's point spread function (PSF). This strategy c…
