XMM-Newton view of the Hubble Deep Field-North and Groth-Westphal strip regions
Abstract
We report the progress on our analysis of two deep XMM observations in the areas of Hubble Deep Field-North and the Groth-Westphal Strip field. We present the source detection method, Monte-Carlo simulation on source detection, and our preliminary Log N - Log S relations. Comparing these two fields and other fields in literature, we find up to ∼ 30 in number counts near our flux limits, which are most likely to be due to cosmic variance. This serves as a pilot study for a more systematic investigation. The nature of the X-ray sources in the Groth-Westphal field is also discussed in terms of hardness ratios, morphology and spectroscopic properties.
