The OPTX Project I: The Flux and Redshift Catalogs for the CLANS, CLASXS, and CDF-N fields
L. Trouille, A. J. Barger, L. L. Cowie +2
We present the redshift catalogs for the X-ray sources detected in the Chandra Deep Field North (CDF-N), the Chandra Large Area Synoptic X-ray Survey (CLASXS), and the Chandra Lock…
Spatially resolved X-ray spectra of NGC 4258
Y. Yang, B. Li, A. S. Wilson +1
We report a spatially resolved, X-ray spectral analysis of NGC 4258 using archival {\it Chandra} and {\it XMM-Newton} observations. The {\it XMM-Newton} spectra of the nuclear regi…
The superflares of soft Gamma-ray repeatres: giant quakes in solid quark stars?
R. X. Xu, D. J. Tao, Y. Yang
Three times of supergiant flares from soft -ray repeatres are observed, with typical released energy of erg. A conventional model (i.e., the magnetar model) fo…
Spatial Correlation Function of the Chandra Selected Active Galactic Nuclei
Y. Yang, R. F. Mushotzky, A. J. Barger +1
We present the spatial correlation function analysis of non-stellar X-ray point sources in the Chandra Large Area Synoptic X-ray Survey of Lockman Hole Northwest (CLASXS). Our 9 AC…
Chandra X-ray Observation of NGC 4151
Y. Yang, A. S. Wilson, P. Ferruit
We present Chandra X-ray observations of the nearby Seyfert 1.5 galaxy NGC 4151. The images show the extended soft X-ray emission on the several hundreds of pc scale with better se…
Chandra Observations and the Nature of the Anomalous Arms of NGC 4258 (M 106)
A. S. Wilson, Y. Yang, G. Cecil
This paper presents high resolution X-ray observations with Chandra of NGC 4258 and infers the nature of the so called ``anomalous arms'' in this galaxy. The anomalous arms dominat…
