Abstract:
We present the X-ray spectra of 86 optically identified sources in the
13H XMM-Newton/Chandra deep field which have >70 X-ray counts. The
majority of these sources have 2-10keV fluxes between 10-15 and
5x10-14erg/cm2/s. The sample consists of 50 broad-line active
galactic nuclei (BLAGN), 25 narrow emission-line galaxies (NELGs), six
absorption-line galaxies and five Galactic stars. The majority (42/50)
of the BLAGN have X-ray spectra which are consistent with a power-law
shape.
Description:
The 13H field was observed three times with XMM-Newton for a total
exposure time of 200ks.
Optical spectroscopic observations were carried out in 2002 and 2003
at the William Herschel Telescope, using the AF2/WYFFOS multifibre
positioner and spectrograph, and at the W.M. Keck observatory, using
the LRIS and DEIMOS multi-object spectrographs.
