Jupiter's Ammonia Distribution Derived from VLA Maps at 3--37 GHz
I. de Pater, R. J. Sault, M. H. Wong +3
We observed Jupiter four times over a full rotation (10 hrs) with the upgraded Karl G. Jansky Very Large Array (VLA) between December 2013 and December 2014. Preliminary results at…
Environmental Monitoring Requirements for the ngVLA
T. K. Sridharan, J. G. Mangum, B. Butler
Measurement of environmental parameters is one of the basic requirements for the proper operation of a telescope. This memo is intended to provide guidance for the measurement accu…
Expected Performance of the ATLAS Experiment - Detector, Trigger and Physics
The ATLAS Collaboration, G. Aad, E. Abat +2604
A detailed study is presented of the expected performance of the ATLAS detector. The reconstruction of tracks, leptons, photons, missing energy and jets is investigated, together w…
The Expanded Very Large Array
R. Perley, P. Napier, J. Jackson +9
In almost 30 years of operation, the Very Large Array (VLA) has proved to be a remarkably flexible and productive radio telescope. However, the basic capabilities of the VLA have c…
Imaging Stellar Radio Photospheres with the Next Generation Very Large Array
C. L. Carilli, B. Butler, K. Golap +2
We perform simulations of the capabilities of the next generation Very Large Array to image stellar radio photospheres. For very large (in angle) stars, such as red supergiants wit…
Pluto's atmosphere observations with ALMA: spatially-resolved maps of CO and HCN emission and first detection of HNC
E. Lellouch, B. Butler, R. Moreno +6
Following the detection of CO and HCN in Pluto's atmosphere, we report on new ALMA observations of Pluto with two main goals: (i) obtaining spatially-resolved measurements (~0.06''…
Detection of CO and HCN in Pluto's atmosphere with ALMA
E. Lellouch, M. Gurwell, B. Butler +16
Observations of the Pluto-Charon system, acquired with the ALMA interferometer on June 12-13, 2015, have yielded a detection of the CO(3-2) and HCN(4-3) rotational transitions from…
An intense thermospheric jet on Titan
E. Lellouch, M. A. Gurwell, R. Moreno +7
Winds in Titan's lower and middle atmosphere have been determined by a variety of techniques, including direct measurements from the Huygens Probe over 0-150 km, Doppler shifts of…
Exploring Io's atmospheric composition with APEX: first measurement of 34SO2 and tentative detection of KCl
A. Moullet, E. Lellouch, R. Moreno +3
The composition of Io's tenuous atmosphere is poorly constrained. Only the major species SO2 and a handful of minor species have been positively identified, but a variety of other…
High Resolution, Wide Field, Narrow Band, Snapshot Imaging
C. L. Carilli, E. Murphy, V. Rosero +4
We investigate the imaging performance of an interferometric array in the case of wide field, high resolution, narrow band, snapshot imaging. We find that, when uv-cell sizes are s…
Gas Analyses of First complete JET Cryopump Regeneration with ITER-Like Wall
S. Grunhagen Romanelli, S. Brezinsek, B. Butler +12
Analytical results of a complete JET cryopump regeneration, including the nitrogen panel, following the first ITER-Like Wall campaign are presented along with the in-situ analyses…
The Caltech-NRAO Stripe 82 Survey (CNSS) Paper II: On-The-Fly Mosaicing Methodology
K. P. Mooley, S. T. Myers, D. A. Frail +4
Telescope slew and settle time markedly reduces the efficiency of wide-field multi-epoch surveys for sensitive interferometers with small fields of view. The overheads can be mitig…
Next Generation Very Large Array Memo No. 5: Science Working Groups -- Project Overview
C. L. Carilli, M. McKinnon, J. Ott +17
We summarize the design, capabilities, and some of the priority science goals of a next generation Very Large Array (ngVLA). The ngVLA is an interferometric array with 10x larger e…
The Pulsar Search Collaboratory: Discovery and Timing of Five New Pulsars
R. Rosen, J. Swiggum, M. A. McLaughlin +68
We present the discovery and timing solutions of five new pulsars by students involved in the Pulsar Search Collaboratory (PSC), a NSF-funded joint program between the National Rad…
Structure of the outer layers of cool standard stars
S. Dehaes, E. Bauwens, L. Decin +6
Context: Among late-type red giants, an interesting change occurs in the structure of the outer atmospheric layers as one moves to later spectral types in the Hertzsprung-Russell d…
An Overview of the 2014 ALMA Long Baseline Campaign
ALMA Partnership, E. B. Fomalont, C. Vlahakis +246
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) wavel…
Subsurface Thermophysical Properties of Europa's Leading and Trailing Hemispheres as Revealed by ALM
A. E. Thelen, K. de Kleer, M. Camarca +4
We present best-fit values of porosity -- and the corresponding effective thermal inertiae -- determined from three different depths in Europa's near-subsurface (~1-20 cm). The por…
The thermal emission of Centaurs and Trans-Neptunian objects at millimeter wavelengths from ALMA observations
E. Lellouch, R. Moreno, T. Müller +9
The sensitivity of ALMA makes it possible to detect thermal mm/submm emission from small/distant Solar System bodies at the sub-mJy level. Measured fluxes are primarily sensitive t…
