1 The FLAMINGOS Extragalactic Survey
Richard Elston Anthony Gonzalez Mike Brown (NOAO) Yen-Ting Lin (Illinois) Arjun Dey (NOAO) Eric McKenzie (Florida) Mark Dickinson (NOAO) Joe Mohr (Illinois) Peter Eisenhardt (JPL) Nick Raines (Florida) Buell Jannuzi (NOAO) Adam Stanford (IGPP/Davis) Daniel Stern (JPL/Caltech)

2 The FLAMINGOS Extragalactic Survey
Target Area: 10 deg2 (90 pointings) Target Depth: Ks=20.5, J=22 (Vega) Location: Both NDWFS regions KPNO 2m + FLAMINGOS NOAO Large Survey Program Final observations: October 2004

3 Motivation Galaxy Evolution Galaxy Cluster Evolution
Near-infrared observations provide unique leverage. Galaxy Evolution Star Formation History Mass Accretion History Correlation Function at z=1-2 Galaxy Cluster Evolution Statistical Cluster Sample at z=1-2 Evolution of Cluster Galaxies Cosmological Parameters

7 Northern Field (Bootes)
4.65 deg2 complete VLA SIRTF NDWFS GALEX Chandra

8 Southern Field (Cetus)
2.11 deg2 complete, 14 nights remaining in Fall 2004 FIRST, SIRTF, NDWFS, GALEX, XMM

9

10 Survey Status Have imaged 6.8 sq. degrees with 14 nights remaining
Averaging ~50% usable nights so far Expect to have ~8-8.5 sq. degrees by end of 2004 Bootes: 4.65 sq. deg Cetus: ~3.5-4 sq. deg Data >80% reduced Initial series of papers planned for summer/fall

11 Data Products and Data Release
J & Ks merged photometric catalog SExtractor output Subarcsecond astrometry Merged with NDWFS catalog Bootes data release planned for late 2004 Cetus data release planned for spring 2005

12 The FLAMINGOS Extragalactic Survey: First High-Redshift Cluster Candidates
Preliminary detection using wavelets for J-Ks= Will eventually utilize photo-z’s (BVIJKs)

13 Summary The FLAMINGOS Extragalactic Survey is almost complete!
Last observations in fall 2004 Final area ~8-8.5 deg2 Complete Bootes data release by late 2004 Matched J & Ks catalogs Plan to also release merged catalogs with NDWFS Key element of the large multiwavelength effort in NDWFS
