2. Characteristics  Slews @90 deg/hr, average 70 deg long, 30 deg 2 area.  PSF similar to pointed observations, slightly extended in slew direction.  15 seconds exposure (10 seconds eff. on-axis).  Low background, typically 0.3c / source box  Positional accuracy: 8” (1σ)  Flux limit: - Total band (0.2-12 keV): 1.2x10 -12 ergs/s/cm 2 - Total band (0.2-12 keV): 1.2x10 -12 ergs/s/cm 2 - Hard band (2-12 keV): 4x10 -12 ergs/s/cm 2 - Hard band (2-12 keV): 4x10 -12 ergs/s/cm 2 - Soft band (0.2-2 keV): 6x10 -13 ergs/s/cm 2 - Soft band (0.2-2 keV): 6x10 -13 ergs/s/cm 2 CF: RASS - 3x10 -13, HEAO-1 - 3x10 -11 CF: RASS - 3x10 -13, HEAO-1 - 3x10 -11 Read et al, 2006, PASJ - Scientific highlights Esquej et al, 2007, A&A – High variability galaxies Saxton et al, 2007, A&A (in prep) – Full description

3. Catalogues  XMMSL1: catalogue of slew sources released May 2006. Revs 314-978, 2700 clean sources (DET_ML>10), 259 hard-band selected (2-12 keV) sources, 6200 deg^2 Revs 314-978, 2700 clean sources (DET_ML>10), 259 hard-band selected (2-12 keV) sources, 6200 deg^2 Available from XMM Science Archive: Available from XMM Science Archive: http://xmm.vilspa.esa.es/xsa/  Delta-1: To be released end of this month giving total of 4000 clean sources, 400 hard band. From 10200 deg^2 (20% of sky ignoring overlaps)  Intention to release further Deltas every 6 months

4. Sky Coverage XMMSL1 + Delta-1 (Galactic coords) [ 20% of sky } + 150 unsearched slews [ total 30% of sky]

5. 400 hard band sources (2-12keV) 4000 sources: blue=hard, light red=soft Sources from XMMSL1+Delta-1 QSO B1101+3828 1A 1103+38

6. Identifications (XMMSL1) Cross-correlated with Simbad, NED, HEASARC. Found counterparts for 55% of sources.

11. Extended sources 15% of sources extended Associations with 81 Zwicky/Abell clusters

12. Possible new SNR in galactic plane ?

14. Correlations with ROSAT - 60% of sources correlate with ROSAT (non-extended, DET_ML>10) - 1% show variability by > factor of ten Mean rate : XMM-slew/ROSAT~10

15. High Variability – soft band sources Flare stars – 1 Eclipsing binary - 2 AGN – 4 (QSO, Sy 1.9, Sy 1.5, Sy1) Candidate tidal disruption events – 2 ( incl NGC 3599 @ 11.4 Mpc ) Dwarf Nova - 1 Probable new Nova in LMC – 1 ( XMMSL1 J060636.2-694932 ) Same source types as ROSAT found to be highly variable Flux increase by > factor 20

16. High Variability – hard band sources ?? - Little possibility currently to get upper limits from a hard band wide area catalogue. - In future, the XMM slew survey may be used for this purpose. - By the time of the Simbol-X launch the XMM slew survey should cover ~ 60 % of the sky.

19. Summary XMM slew data will present a resource for medium- energy X-ray data, covering ~60% of the sky by 2013, with an astrometic accuracy of ~8”. Good coverage of large extended sources VO-compliant, Upper Limit Server being developed to aid inter-mission variability analysis

20. Fast Slew: fast turn-around Variability analysis o Retrieve SDF from XSA – 10-20 days after observation o Initial processing to event file – 1 day o Split into discrete images – 1 day o Source search – 1 day o Calculate RASS upper limits, cross-correlate with NED, SIMBAD – 1 day Can find high variability slew sources 14-24 days after slew in time for follow-up
