The stellar population of the Rosat North Ecliptic Pole survey. II. Spectral analysis
L. Affer, G. Micela, T. Morel
X-ray surveys allow to identify young, main-sequence stars in the solar neighborhood. Young, stellar samples, selected according to their activity, can be used to determine the ste…
The ROSAT North Ecliptic Pole Survey: The X-ray Catalog
J. Patrick Henry, Christopher R. Mullis, Wolfgang Voges +4
The sky around the North Ecliptic Pole (NEP), at (2000) = 18, (2000) = +66\degr33\arcmin39\arcsec, has the deepest exposure of the entire {\it ROSAT} All - Sky Su…
Spatial Correlation Function of X-ray Selected AGN
C. R. Mullis, J. P. Henry, I. M. Gioia +4
We present a detailed description of the first direct measurement of the spatial correlation function of X-ray selected AGN. This result is based on an X-ray flux-limited sample of…
RXJ1716.6+6708: a young cluster at z=0.81
I. M. Gioia, J. P. Henry, C. R. Mullis +2
Clusters of galaxies at redshifts nearing one are of special importance since they may be caught at the epoch of formation. At these high redshifts there are very few known cluster…
