Pan-STARRS - The PS1 PS2 Wide Area Survey for NEOs

摘要

The Panoramic Survey Telescope and Rapid Response System or Pan-STARRS is a wide field sky survey system developed at the University of Hawaii that now includes both the PS 1 and PS2 telescopes and extensive cyber-infrastructure for image processing, machine learning, and very large hierarchical databases. The emergent Pan-STARRS infrastructure is described together with the survey goals for the next five years of Pan-STARRS static sky and time domain science. PS1 has produced the premier photometric sky catalog with better than 7 milli-mag accuracy across the sky and with the best tie to an absolute AB photometric calibration. The catalog for mean positions has been placed on the Gaia frame, and thus extends the Gaia frame to 23rd magnitude. The Pan-STARRS catalog has thus becomes the standard reference for astronomical photometry. Pan-STARRS leads the world in discovery of Near Earth Objects, Supernovae, and rare but important objects including the first Interstellar Object, binary neutron star mergers, and super-luminous supernovae. Pan-STARRS together with the CFIS survey will provide the galaxy photometry necessary for the Euclid Mission to perform the tomography of the dark matter content of the universe. With the addition of the PS2 facility to the Pan-STARRS Observatories we have doubled our survey power and discovery rates.
