X-ray Luminosity Functions of Active Galactic Nuclei
Takamitsu Miyaji
In this proceedings paper, I overview the current status of the X-ray luminosity function of AGNs in the soft (0.5-2 keV) band, extended using XMM-Newton and Chandra survey data. W…
Faint Source Counts from the Off-source fluctuation Analysis on the Deepest Chandra Fields
Takamitsu Miyaji, Richard E. Griffiths
We show the results of the fluctuation analysis applied to the off-source areas from the two 1 Million second Chandra Deep Fields, including our new results on the Chandra Deep Fie…
First Results from the XMM-Newton Observation in the Groth-Westphal Survey Strip Region
T. Miyaji, R. E. Griffiths
We present the first results of the XMM-Newton observation on the Groth-Westphal Strip Field. The scheduled exposure time was 70 [ks]. We first analyzed about 50 [ks] of calibrated…
Resolving the X-ray Spectral Paradox: XMM-Newton Spectra of Faint Sources in the Lockman Hole
R. E. Griffiths, A. Ptak, T. Miyaji
Using 100ks of XMM-Newton data on the Lockman Hole, we show how the X-ray background 'spectral paradox' is being resolved. We find the summed spectra of the Type I AGN, Type II AGN…
Soft X-ray AGN Luminosity Function from ROSAT Surveys I. Cosmological Evolution and Contribution to the Soft X-ray Background
Takamitsu Miyaji, Guenther Hasinger, Maarten Schmidt
We investigate the evolution of the 0.5-2 keV soft X-ray luminosity function (SXLF) of active galactic nuclei (AGN) using results from ROSAT surveys of various depth, ranging from…
A Search For Large-Scale Structure at High Redshift
A. J. Connolly, A. S. Szalay, A. K. Romer +4
We present new and exciting results on our search for large-scale structure at high redshift. Specifically, we have just completed a detailed analysis of the area surrounding the c…
