SASIR: A Collaborative Astronomy Effort Between the Universidad Nacional Autónoma de México (UNAM), the University of California, Instituto National de Astrofísica, Óptica y Electrónica (INAOE), & the University of Arizona
Overview
We are working to build the world's most ambitious infrared survey of the entire night's sky: the aim is to repeatedly image the sky to a level 100 - 500 times deeper than the 2MASS survey, uncovering the most distant objects known to mankind and revealing the transient universe as never seen before. Gathering around a common set of scientific goals, we hope to foster a stronger connection between the Mexican and US science and technology communities as well as raise the educational awareness of astronomy to a broad community.
More Details
In the mountains of Baja California, at the San Pedro Mártir (SPM) Observatory, a 6.5 meter telescope will be constructed over the next several years and the survey will begin with the largest infrared camera ever constructed. The YJHKs survey, based upon a camera with ~124 2k x 2k IR arrays and a field of view of 0.8 degrees, is expected to begin in 2017 and last for 4 years. Data will be made readily available to the UC and Mexican astronomy communities through co-located data centers.
