Updates to ALMA Site Properties: using the ESO-Allegro Phase RMS database -- ALMA Memo 624
Luke T. Maud, Andrés F. Pérez-Sánchez, Yoshiharu Asaki +3
We present a long-term overview of the atmospheric phase stability at the Atacama Large Millimeter/submillimeter Array (ALMA) site, using >5 years of data, that acts as the success…
Self-calibration and improving image fidelity for ALMA and other radio interferometers
A. M. S. Richards, E. Moravec, S. Etoka +4
This manual is intended to help ALMA and other interferometer users improve images by recognising limitations and how to overcome them and deciding when and how to use self-calibra…
Gas temperature structure across transition disk cavities
M. Leemker, A. S. Booth, E. F. van Dishoeck +8
[Abridged] Most disks observed at high angular resolution show substructures. Knowledge about the gas surface density and temperature is essential to understand these. The aim of t…
Spatio-kinematical model of the collimated molecular outflow in the water-fountain nebula IRAS 16342-3814
D. Tafoya, G. Orosz, W. H. T. Vlemmings +2
In this work we aimed to describe the three-dimensional morphology and kinematics of the molecular gas of the water-fountain nebula IRAS 16342-3814. In order to do this, we retriev…
Deep into the Water Fountains: The case of IRAS 18043-2116
A. F. Pérez-Sánchez, D. Tafoya, R. García López +2
(Abridged) The formation of large-scale (hundreds to few thousands of AU) bipolar structures in the circumstellar envelopes (CSEs) of post-Asymptotic Giant Branch (post-AGB) stars…
The wonderful complexity of the Mira AB system
S. Ramstedt, S. Mohamed, W. H. T. Vlemmings +17
We have mapped the CO(3-2) line emission around the Mira AB system at 0.5 resolution using the Atacama Large Millimeter/submillimeter Array (ALMA). The CO map shows amazing complex…
Submillimeter H2O masers in water-fountain nebulae
D. Tafoya, R. Franco-Hernández, W. H. T. Vlemmings +2
We report the first detection of submillimeter water maser emission toward water-fountain nebulae, which are post-AGB stars that exhibit high-velocity water masers. Using APEX we f…
A synchrotron jet from a post-AGB star
A. F. Pérez-Sánchez, W. H. T. Vlemmings, D. Tafoya +1
(Abridged) The evolution of low- and intermediate-initial-mass stars beyond the asymptotic giant branch (AGB) remains poorly understood. High-velocity outflows launched shortly aft…
Linear polarization of submillimetre masers. Tracing magnetic fields with ALMA
A. F. Pérez-Sánchez, W. H. T. Vlemmings
(Abridged) The goal of this work is to investigate if SiO, H2O and HCN maser emission within the ALMA frequency range can be detected with observable levels of fractional linear po…
H2O Maser Polarization of the Water Fountains IRAS 15445-5449 and IRAS 18043-2116
A. F. Pérez-Sánchez, W. H. T. Vlemmings, J. M. Chapman
We present the morphology and linear polarization of the 22-GHz H2O masers in the high-velocity outflow of two post-AGB sources, d46 (IRAS 15445-5449) and b292 (IRAS 18043-2116). T…
