Title
Teen Astronomy Cafés (NOAO)
Abstract
The National Optical-Infrared Astronomy Research Laboratory (formerly NOAO) started the Teen Astronomy Cafés program to excite the interest of talented youth in STEM. One Saturday a month during the academic year, high school students interact with expert astronomers who work with big data. Students learn about killer asteroids, exoplanets, lives and deaths of stars, variable stars, black holes, the structure of the universe, gravitational lensing, dark matter, colliding galaxies, and more. The format for the cafés is a short presentation by an astronomer, a computer-based lab activity and a discussion during lunch. Presently, 50% of the students are from schools with failing grades (by the Arizona Department of Education). Over 50% are girls. Our science cafés demonstrate that scientists play a key role in increasing student interest and curiosity about science research and in helping students get a sense of scientists as people. The cafés also demonstrate that scientists can help students see how research connects with issues important to society and with students’ daily lives.

Title
Kubernetes as an Astronomical platform, a technical review (University of Illinois)
Abstract
In this talk, I will review the basic concepts of Kubernetes and how these are being applied within the context of Astronomy. In particular, Kubernetes has been already adopted by surveys like DES and LSST and is slowly making its way into other projects. I will do a live demo of a simple deployment and how this can be expanded into a full production-like system.

LSST/DESC Plans for Computing and Workflow (University of Edinburgh)
Abstract
DESC is the cosmology collaboration for LSST, the Large Synoptic Survey Telescope, which is currently under construction at Cerro Panchon, Chile. Much of DESC\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'s work is computational, requiring large data processing facilities and tools. I will discuss DESC\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'s current plans for workflow and processing, starting from the catalogs provided by data management and ending with cosmological constraints

Title
New Infrastructure and Processes for Time-Domain Followup (Gemini Observatory)
Abstract
Time domain and multi-messenger astrophysics are rapidly growing and important modes of observational astronomy. The commissioning of LSST and the increasing sensitivity of facilities such as LIGO and IceCube mean that both rapid-response and long-term flexible scheduling capabilities will be essential. Significant effort by a variety of groups is being put into developing the components of a follow-up system for dynamically turning survey alerts into data. This system consists of: 1) brokers that will aggregate, classify, and filter alerts; 2) Target Observation Managers (TOMs) that are used by science teams for prioritizing targets and managing observations and data; and 3) observatory interfaces, schedulers, and facilities along with data reduction software and science archives. These tools will also be beneficial to all users of these facilities. This presentation will review the current status of this developing network with emphasis on the efforts of the Astronomical Event Observatory Network (AEON), a collaboration between Las Cumbres Observatory, NOAO/SOAR, and Gemini, and outstanding issues will be discussed.

Title
Desafios da infraestrutura e instrumentação astronômica no Brasil para a próxima década (LNA)
Abstract
Nas últimas duas décadas a astronomia optica e infravermelha do Brasil teve um grande crescimento, tanto em número de pessoas quanto em publicações e isto reflete no reconhecimento internacional de nossa comunidade. Este crescimento foi alavancado em boa parte pelo maior acesso a novos telescópios e instrumentação, seja no país seja por acordos internacionais. Em 2020 e 2021 vencem os atuais acordos do SOAR e do Gemini e fazem 10 anos do workshop promovido pelo LNA para avaliar a questão da infraestrutura observacional. Quais são os desafios científicos para a nova década e o que nossa comunidade precisa em termos de instrumentação para poder participar ativamente das respostas a estes desafios? Neste seminário não trazemos as respostas prontas a estas questões, mas sim levantamos a discussão e os pontos a serem discutidos para que toda a comunidade possa participar.

Title
LSST and Data Facilities to Enable Science with Billions of Objects (University of Pittsburgh)
Abstract
The Large Synoptic Survey Telescope will open new frontiers in large-scale data analysis in astronomy. In this talk I will discus the opportunities and current implementation of data access and analysis in the LSST Project and in the Dark Energy Science Collaboration. The LSST Science Platform is being built to enable the LSST community to explore the rich and large datasets from from LSST. While the LSP may not be fully operational until the beginning of the LSST Operations in late 2022, development and prototyping efforts are currently underway to understand both the technical scope and user interactions with this ambitious platform. In parallel to the LSST Project construction efforts, the wider LSST scientific community is preparing for LSST. In particular, the Dark Energy Science Collaboration (DESC) was formed to fully exploit the ability of LSST to determine the nature of dark energy. In advance of data from LSST, DESC is preparing a series of Data Challenges to develop and verify scientific and basic data processing pipelines. These data challenges are helping both DESC and the LSST Project explore and understand the opportunities and challenges of exploring terabyte-scale image datasets with catalogs with billions to trillions of entries.

Title
UK Ambitions for Astronomy in the LSST Era (University of Edinburgh)
Abstract
The Large Synoptic Survey Telescope promises to revolutionalise many aspects of optical astronomy, most notably dealing with the transient universe. UK-based astronomers have a particular opportunity, since the UK is part of several other significant facilities on a similar timescale--for example, Euclid, 4MOST, and SKA--yielding a possibility to secure leadership in a number of areas, including dark energy, solar system science, and transients. Recognising this, the UK community has formed a consortium with representation from every UK-based astronomy group, to encapsulate its ambitious plans for LSST and to secure funding for a substantial programme of R&D, in the lead up to the beginning of telescope operations in 2022. Through this consortium, LSST:UK has secured data rights for 100 Affiliate PIs (plus the associated 400 Junior Associates), and embarked on an 8-year research and development programme that will yield a UK-based LSST Data Access Centre, tailored to the specific requirements of priority UK astronomy goals. In this talk, I will share highlights from the UK programme to date, including an alert-handling service that is being trialled on the Zwicky Transient Facility, large-scale database ingest and query experiments, toward the 35 billion objects that LSST is predicted to observe, and a fledgling cloud-based deployment of an analysis platform that will be at the heart of the UK DAC. I will also preview the plans for the next phase of work, during 2019--2023, which are likely to involve closer international collaboration on provisioning of data and associated analysis services as well as the finalisation of plans for UK-led User-generated Products, as we transition from the construction to the commissioning phase of LSST.
