The Scientific Quest for High Angular ResolutionOn 7 January 2020, the NRAO and the ngVLA Project will convene a Special Session onThe Scientific Quest for High Angular Resolution(https://science.nrao.edu/science/meetings/2020/aas235/the-scientific-quest-for-high-angular-resolution) at the American Astronomical Society winter meeting
(https://aas.org/meetings/aas235) in Honolulu, Hawaii. This Special Session will highlight recent scientificbreakthroughs enabled by imaging at high angular resolution. It will feature a session of invited oralpresentations from 2:00 - 3:30 p.m. local time, plus an associated day-long poster session withcontributed presentations. Submissions of poster abstracts have closed. In the coming weeks, Joan Wrobel willconnect with poster presenters to offer ngVLA-themed templates and assistance with poster printing andshipping.
ngVLA Mentioned in 450+ PublicationsSince 2015, the acronym ngvla has appeared in over 450 publications indexed in the SAO/NASA AstrophysicsData System. This metric quantifies the remarkable role of the scientific and engineering communities inadvancing the ngVLA concept.
Compact Objects and Energetic Phenomena in the Multi-Messenger EraOn 14-16 July 2020, the NRAO and the ngVLA Project will convene a science conference titled CompactObjects and Energetic Phenomena in the Multi-Messenger Era (https://go.nrao.edu/ngvla20) in Saint Paul,Minnesota, USA. Pre-registration is open. SOC co-chairs are Nicole Lloyd-Ronning (LANL) and TomMaccarone (Texas Tech University). A diverse and exciting group of invited speakers(http://www.cvent.com/events/compact-objects-and-energetic-phenomena-in-the-multi-messenger-era/speakers-7d584037bafd41c58bad69072788dce7.aspx?p=73) has been announced. Registration and abstract submission willopen 1 December.
The ALMA2030 Vision: Design Considerations for the Next ALMACorrelator
A meeting to discuss considerations for the design of the next ALMA correlator(http://go.nrao.edu/ngALMACorrelator) will be held in Charlottesville, Virginia February 11-13, 2020.

Two telescopes at the 5000m ArrayOperations Site achieved first ALMAfringes on 21 October 2009.
The purpose of this meeting is to bring together experts on the ALMA system and modern digital correlatordesign in order to:
1. discuss ALMA design requirements for the next generation ALMA correlator that enables the ALMA2030vision;
2. share pros and cons of recent and currently under design correlator architectures; and
3. identify challenges for implementing and deploying a new ALMA correlator.
Ultimately we hope this meeting encourages and informs the submission of viable designs for the next ALMAcorrelator in the near future.
Registration opens November 12, 2019! (http://go.nrao.edu/ngALMACorrelator) Visit the conference website(http://go.nrao.edu/ngALMACorrelator) for more information.
ALMA Program NewsAl Wootten
Cycle 7 ObservingThe current ALMA configuration is approximately C43-3 (0.5 km maximumbaseline, 100 GHz beam 1.4 arcsec). Ten years ago, on Monday, 21 October 2009,ALMA achieved its first fringes (https://www.almaobservatory.org/en/press-release/alma-first-fringes-at-chajnantor/) with two antennas at the 5000m elevationArray Operations Site By the end of November 2019, ALMA will contract to its mostcompact configuration. Just after the tenth anniversary, ALMA briefly moved to areduced operations level to ensure employee safety during a State of Emergencydeclared by the government of Chile. Operations at the site resumed on 28 October,after that State of Emergency was lifted.
Fourth ALMA Science ConferenceTwo hundred thirty-five scientists attended the ALMA Science Conference in Cagliari(https://indico.ict.inaf.it/event/789/overview) (Sardinia, Italy) on 14-18 October 2019, the fourth major scienceconference since the beginning of operations. This latest conference featured 220 talks and posters coveringALMA results from the Sun to the Era of Recombination. The First ALMA Science Conference – Science withthe Atacama Large Millimeter Array (ALMA) – was held twenty years ago at the Carnegie Institution ofWashington on 6-8 October 1999 (ASP Conference Series, Volume 235).
AAS – Honolulu Special Session On Monday, 6 January 2020, from 2:00 - 3:30 p.m., the NRAO will convene a Special Session titledBreakthrough Science with the Atacama Large Millimeter/submillimeter Arra(https://science.nrao.edu/science/meetings/2020/aas235/breakthrough-science) y(https://science.nrao.edu/science/meetings/2020/aas235/breakthrough-science) featuring results from ALMA LargePrograms and other related science, at the AAS winter meeting in Honolulu, Hawaii. The speaker list includes:Sean Dougherty, Fabian Walter, Eva Schinnerer, Dan Marrone, Ilse Cleeves, and Sean Andrews.
Space VLBI Science Conference AnnouncementWalter Brisken, on behalf of the Space VLBI LOC & SOC
Registration and abstract submission are now open for Space VLBI 2020: Science and Technology Futures(https://go.nrao.edu/SpaceVLBI2020) , which will be held 28-30 January 2020, in Charlottesville, Virginia andwill be second meeting in The Future of High-Resolution Radio Interferometry in Space series. Please notethese important deadlines:
Oral Abstract Submission Deadline 22 November 2019Poster Abstract Submission Deadline 8 January 2020
Space VLBI 2020 will focus on mission concepts and supporting technology developments to enable thehighest angular resolution observations at centimeter and shorter wavelengths (30+ GHz observingfrequencies).The meeting will highlight recent scientific advances and developments in the motivations forfuture space-based Very Long Baseline Interferometry (VLBI) and the resulting technical requirements andchallenges. Of particular interest are contributions in areas such as:
Science at extremely high angular resolutions;
Apertures size, and performance for space apertures;
Receiver and detector technology status and performance;
Data volume and transport;
Clocks and synchronization;
Orbital dynamics and u-v plane coverage;
Orbit determination;
Data processing for correlation and analysis;
VLBI simulations for science cases;
Optimization for mission concepts; and
Concepts (e.g., one large aperture vs. many small apertures in space).
There is also interest in exploring the opportunities made available by recent innovations for VLBI and in spacemissions.

Career OpportunitiesALMA Postdoctoral Fellows (http://jobs.jobvite.com/nrao/job/owEvbfwA) : The Joint ALMAObservatory (JAO) is actively recruiting for postdoctoral fellowship positions to join the ALMA scienceoperations group in Santiago, Chile. ALMA Postdoctoral Fellows will be appointed for a period of three yearsand will spend 50% of their time dedicated to their personal scientific research. The remaining time will bespent in support of ALMA operations, including observing at the ALMA Operations Support Facility near SanPedro de Atacama, Chile for hands-on interaction with the telescope. The goal of these fellowships is to offerearly career scientists the opportunity to enhance their research programs through involvement in scienceactivities and interactions with experienced staff at the world's foremost observatory for submillimeterastronomy.

From the ArchivesEllen Bouton
About this month's photo: NRAO chose the Rohr Corporation in Chula Vista,California, to build the 36 Foot Telescope, and Rohr decided to fabricate the surface inone piece rather than use multiple panels, a process which proved challenging. Thesurface was finally completed in late February 1966 and the 13,000 pound, 36 footdish was transported by road from the Chula Vista factory to the base of Kitt Peak,accompanied by California and Arizona State Police escorts. The 425-mile trip took
ten days and the entire Rohr convoy included eight truckloads of telescope components. Due to problems anddelays in completing the dome to house the telescope, concerns about the impact of inclement weatherconditions on top of the mountain, and ongoing repairs to the road up the mountain, the dish structureremained at the bottom of Kitt Peak for many months – under guard lest it be stolen or used as target practiceby Arizona locals. In this photo, taken by John Hungerbuhler, the dish makes its way slowly from California toTucson.
