Presentation Transcript

  1. Chandra’s Second Decade • Lifetime: ≥15-20 years (RJB’s presentation) • Is all key Chandra science enabled by current proposal and review procedures? • Extremely Large Projects (ELPs): not implemented as “could be accommodated” in current LP/VLPs • But Cycles 10-12: lack >1 Msec projects approved (2 in past 3 cycles) • Orbit is evolving → more observing time available per cycle for next few years Chandra Director’s Office

  2. Large Project at other Observatories • NOAO Survey Program (24): • 1999 → present: up to 20% of observing time per cycle, e.g. NOAO/XMM Cluster Survey, The w Project, NOAO Deep-Wide Survey • Spitzer Legacy Projects (6): • 2000, 50% of observing time in 1st year, e.g. GOODS, SWIRE, SINGS • Herschel Key Projects (42): • 2007, 40% OT, 90% GT: e.g. HERMES, KINGFISH • HST Multi-Cycle Treasury Projects (3): • 2010, 1/3rd of observing time over 3 cycles, e.g. CANDELS, Andromeda Survey,Through a Lens Darkly Chandra Director’s Office

  3. Science Drivers • X-ray coverage of multi-wavelength, surveys: COSMOS, AEGIS, HERMES, CANDELs etc.. • Coordination with new observatories: Herschel, ALMA, JWST • High-spatial-resolution studies of samples of SNRs and Clusters of Galaxies • Survey of local group dwarf galaxies: XRB population studies and search for dark matter decay • WHIM search/confirmation • Survey of M31 to complement Hubble Andromeda Survey • Grating Spectroscopy of more AGN, stars + • Spatially-resolved spectroscopy of nearby AGN • Young star clusters (w/ALMA for disk studies) • AGN timing via regular imaging of (part of) medium- deep PanSTARRS field (7 sq degs) Chandra Director’s Office

  4. X-ray Visionary Projects (XVPs) • Major, coherent science projects needing 3-5 Msecs, no proprietary time, multi-year • Single project approved per call, any remaining time retained for future XVPs • No science limit for first call, consider second and subsequent to facilitate different science categories • Time, Cycle 13: 3 Msec shortfall from previous cycles, ~1.5 Msec (increased efficiency Cycle 13), ~0.5 Msec from Cycle 14 • Funding: scaled up VLP formula Review process: • Notice of Intent with early deadline (~mid-Jan) • Initial Review by augmented set of pundits at regular peer review • Final recommendation from BPP (pundits+chairs) Chandra Director’s Office
