Welcome to the First CLASH Science Team Meeting September 20 – 21, 2010 Granada, Spain
CLASH Fun Facts • 524 HST orbits = 1.22 Megaseconds of exp time, ~4500 exposures (incl. PAR), ~300 GB raw data • We are 32 researchers from 9 countries and 17 institutions, spanning 13 time zones. • Total ground-based telescope time awarded in 2010 based on CLASH: ~370 hours (~1.3 Msec) • Sum of all exposure times for archival x-ray, IR, SZE, Subaru data being used: 4.2 Megaseconds • E-mails exchanged since June 2009: >3,800 • Grams of dark matter to survey: 2.5 x 1046
CLASH Yields a Significant Expansion of SL Cluster Data Strongly lensing Clusters with 3 or more filters from HST (ACS and/or WFC3) Figure credit: Dan Coe CLASH doubles the number of SL clusters with >3 HST passbands. CLASH has uniform and well-defined sample selection criteria. No SL clusters currently have more than 9 HST passbands – new territory for science.

Curves assume 41.4 month mean lifetime of single string instrument (based on actual HST SI experience). Predicts 50% failure probability for double string occurs at 69 months. R. Doxsey (2009) Sep 2017 May 2019 May 2009 Jan 2011 Sep 2012 May 2014 Jan 2016 Cycle 20 Cycle 19 Cycle 18 ACS is single string, WFC3 is double.
Objectives for this meeting • Energize team … our program begins to execute in 58 days! • Get acquainted: teams that know one another work together better! • Concurrence on high priority science for first year. • Identification of the first CLASH science papers and their lead authors. • Identify outstanding CLASH data mgmt issues and develop solutions before the November data deluge. • Planning for ground-based observing campaigns. • Planning for upcoming telescope proposals. • Concurrence on collaboration policies (authorship, new collaborators, etc.) • Strategize about upcoming 2011 scientific symposia – want strong CLASH coverage at all relevant major meetings. • Enjoy Granada!
