The XMM SSC Bright Source sample * November 2006 Report to the SSC XID

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| > 20o fX > ~ 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. The XMM SSC Bright Source sample • Images used: 237 • Sources in the bright sample: 389 • Sources in the “hard” bright sample: 67 • (56 sources are in common)

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 14Id • Others (MKO,AAT): 19Id TOTAL: 42 nights 244Id 244 Sources Identified (our own spectroscopy)

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

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

8. Status of New Proposals/Projects • 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

9. Papers published so far… • 1) “XMM-Newton observations reveal AGN in apparently • normal galaxies” by Severgnini et al., 2003, A&A, 406,483 2) “The XMM-Newton HBS28 sample: Studying the • obscuration in hard X-ray selected AGNs” by Caccianiga • et al., 2004, A&A, 416, 901 3) “Exploring the X-ray Sky with the XMM-Newton • Bright Serendipitous Survey” by Della Ceca et al., 2004, • A&A,428, 383 4) “XMM-Newton spectroscopy of an X-ray selected sample of RL AGNs” by Galbiati et al., 2004, A&A, 430, 927 5) “An X-ray Bright ERO hosting a Type 2 QSOs” by Severgnini et al., 2006, 451, 859 6) “The stellar content of the XMM-Newton Bright Serendipitous Survey” by Lopez-Santiago et al., A&A, in press.

10. Work/Papers in progress… 6-12 Months Timescale… A paper discussing the classification criteria and the optical properties of the total BSS sample by Caccianiga et al., A paper discussing the cosmological properties (mainly the XLF) of absorbed and unabsorbed AGN in the HBS survey ( 4.5-7.5 kev energy band) by Della Ceca et al.,

11. Work/Papers in progress… 1-2 years timescale… • a paper discussing the X-ray properties of the total • extragalactic XMM BSS sample; • a paper discussing the infrared properties of • the XMM BSS sources with Spitzer data; • a paper discussing the X-ray and optical properties of • the Type 2 QSOs found so far; • a paper discussing the X-ray and optical properties of • the sources with high (>10) X/O flux ratio;
