Surveys have always been among the most widely used tools of astronomers to make sense of the observable Universe. Building on the heritage of such a long tradition, modern astronomy has seen an accelerating pace of survey experiments across the electromagnetic spectrum, devised to answer fundamental questions about cosmology, galaxy formation, the history of our own Milky Way, stellar astrophysics and much much more.
High-energy astrophysics have pioneered all-sky surveys, and the imminent advent of sensitive, large field of view imaging telescopes, such as eROSITA, promise a further revolution, as the emergence of the three-dimensional structure of the cosmic web over the history of the Universe displays very distinctive features when observed in X-rays, where both the most massive collapsed structure (clusters of galaxies) and the most energetic events in the life of galaxies (AGN and Quasars) reveal themselves unambiguously.
AHEAD aims at providing young astronomers the specific theoretical and practical skills to successfully exploit the current and future generation of large surveys. We will include in-depth discussion of both high-energy experiments and multi-wavelength surveys across the entire electromagnetic spectrum. To this end, world class experts in several fields will deliver lectures and conduct hands on sessions, including analysis of real catalogs and data. The students will have the opportunity to interact with renowned scientists in a highly motivating environment.
