A survey of luminous high-redshift quasars with SDSS and WISE II. the bright end of the quasar luminosity function at z ~ 5
Jinyi Yang, Feige Wang, Xue-Bing Wu +13
This is the second paper in a series on a new luminous z ~ 5 quasar survey using optical and near-infrared colors. Here we present a new determination of the bright end of the quas…
Exploratory Chandra observation of the ultraluminous quasar SDSS J010013.02+280225.8 at redshift 6.30
Yanli Ai, Liming Dou, Xiaohui Fan +3
We report exploratory \chandra\ observation of the ultraluminous quasar SDSS J010013.02+280225.8 at redshift 6.30. The quasar is clearly detected by \chandra\ with a possible compo…
X-ray spectral and temporal analysis of Narrow Line Seyfert 1 galaxy Was 61
Liming Dou, Ting-Gui Wang, Yanli Ai +3
We present an analysis of spectrum and variability of the bright reddened narrow line Seyfert 1 galaxy Was~61 using 90 ks archival {\it XMM-Newton} data. The X-ray spectrum in 0.2-…
A survey of luminous high-redshift quasars with SDSS and WISE. I. target selection and optical spectroscopy
Feige Wang, Xue-Bing Wu, Xiaohui Fan +14
High-redshift quasars are important tracers of structure and evolution in the early universe. However, they are very rare and difficult to find when using color selection because o…
