1. The XMM SSC Bright Source sample * November 2006 Report to the SSC XID R. Della Ceca A. Caccianiga T. Maccacaro P. Severgnini F. Cocchia * on behalf of the XMM Survey Science Centre

2. Target of this project To define a sample of spectroscopically identified serendipitous XMM sources at |b| > 20 o f X > ~ 10 -13 erg cm -2 s -1 Primary Selection Camera: the MOS2 detector Bright sample (BS): CR (0.5-4.5 keV) > 0.01 s -1 (~7x10 -14 cgs) “Hard” Bright sample (HBS): CR (4.5-7.5 keV) > 0.002 s -1 (~7x10 -14 )

3. Images used: 237 Sources in the bright sample: 389 Sources in the “hard” bright sample: 67 (56 sources are in common) The XMM SSC Bright Source sample

4. Main BSS observing runs since the beginning of this project (2001)

5. Telescopes used so far.. TNG: 28 nights 124 Id ESO (3.6m/NTT): 11 nights 87 Id Calar Alto (2.2m): 3 nights 14 Id Others (MKO,AAT): 19 Id 244 Sources Identified (our own spectroscopy) TOTAL: 42 nights 244 Id

6. So far… (November 2006) Spectroscopic Identifications bright sample: 337 sources  87% “hard” bright sample: 65 sources  97% Total : 400 X-ray sources, 348 spectr. identified ~ 87%

7. BS HBS Sources 389 67 Identified 337 (87%) 65 (97%) Optical identification & classification BS HBS

8. ON GOING Spitzer Cycle-3 (PI: P. Severgnini) 17 Type 2 AGN extracted from the HBS Sample 7 objects already observed. PLANNED IN THE NEAR FUTURE Detailed ESO/VLT Observations on interesting subclasses of sources: e.g. Optically diluted AGN or high X-ray to optical flux ratios sources or Type 2 QSOs Status of New Proposals/Projects
