Sharing One Sky: SDSS, APOGEE, and Astronomy Outreach

Viña del Mar, Chile, May 25-26, 2016

WORKSHOP OBJECTIVES

The focus of the workshop is astronomy education and public outreach, with a particular focus on sharing strategies and methods, creating cross-cultural and multi-lingual ventures, forming E/PO collaborations, and exploiting the science and international reach of the Sloan Digital Sky Survey (SDSS) and the Apache Point Observatory Galactic Evolution Experiment (APOGEE) — which will soon be operating from parallel sites in the U.S. and Chile —  for fostering these activities. We wish to bring together astronomers, educators, and journalists to achieve the above objectives, and also formulate methods by which we can promote the public face of SDSS and APOGEE within Chile, across the Americas and beyond

Gemini Observatory mini-Workshop: Data Driven Modeling of Spectra using The Cannon

La Serena, Chile, March 17 - 18, 2016

Gemini South Observatory, La Serena, will be holding a mini-workshop on the python code The Cannon with Anna Ho from Caltech on March 17-18. Anna will give two talks on determining spectral abundances with data driven models and also guide participants in two workshop sessions on how The Cannon works using a test data set and a session where people can use the code with their own dataset. We only have space for 30 participants in the workshop sessions although more people can attend the talks.

The Supernovae Through the Ages Conference

Easter Island, Chile, August 9 - 13, 2016

Scientific Rationale

Supernova science has entered a golden age with daily announcements of new discoveries. This rate of discovery is only going to increase as we move to an era of large-scale non-targeted surveys, which will culminate with the LSST. In order to take advantage of this deluge of observations the community needs to evaluate the efficiency and effectiveness of data analysis techniques to ensure that optimal science is achieved. As supernova sample sizes continue to drastically increase, well-observed nearby events will still provide the most direct insights into progenitor properties and explosion mechanisms. Here, the challenge is to obtain multi-wavelength observations at epochs as early as possible post-explosion, where crucial constraints on physics are at their most powerful.

Resolving planet formation in the era of ALMA and extreme AO

Santiago, Chile, May 16 - 20, 2016

Scientific Rationale

Results from ALMA Long Baseline observations and from SPHERE, GPI and other high-contrast AO instruments have given a taste of what to expect over the next few years in the fields of protoplanetary and debris disks, and planet formation. For the first time, these instruments are enabling us to observe the regions where planets form. Already we are finding gaps, holes, spiral wave patterns, and extreme asymmetries in the disks.

Wide-field Variability Surveys: a 21st-century perspective

22nd Los Alamos Stellar Pulsation Conference Series Meeting

San Pedro de Atacama, Chile, Nov. 28 - Dec. 2, 2016
Webpage: http://pulsation2016.contactochilecom.cl/

Scientific Rationale

Astronomy is undergoing a major revolution in the way it approaches its core subject. With the increase in detector efficiency and size and the availability of ever more powerful computers, wide-field surveys, once few in number, have become increasingly common – and indeed, it is clear that the field will be largely dominated by massive wide-field surveys, photometric and spectroscopic alike, in the not-too-distant future.

At this special transition moment between “classical” and survey-based astronomy, we are faced with important challenges on how to properly handle, process and analyze the increasingly large datasets that are continuously amassed by these surveys. Astronomers must increasingly work together with computer scientists and statisticians. Entirely new fields, such as the booming but fairly young field of Astrostatistics, are emerging in the process.
