SDSS quasars in the WISE preliminary data release and quasar candidate selection with optical/infrared colors
Xue-Bing Wu, Guoqiang Hao, Zhendong Jia +2
We present a catalog of 37,842 quasars in the SDSS Data Release 7, which have counterparts within 6" in the WISE Preliminary Data Release. The overall WISE detection rate of the SD…
Eight new quasars discovered by LAMOST in one extragalactic field
Xue-Bing Wu, Zhendong Jia, Zhaoyu Chen +18
We report the discovery of eight new quasars in one extragalactic field (five degree centered at RA=, Dec=) with the LAMOST commissioning observation…
A very bright i=16.44 quasar in the `redshift desert' discovered by LAMOST
Xue-Bing Wu, Zhaoyu Chen, Zhendong Jia +18
The redshift range from 2.2 to 3, is known as the 'redshift desert' of quasars because quasars with redshift in this range have similar optical colors as normal stars and are thus…
Quasar candidate selection and photometric redshift estimation based on SDSS and UKIDSS data
Xue-Bing Wu, Zhendong Jia
We present a sample of 8498 quasars with both SDSS optical and UKIDSS near-IR photometric data. With this sample, we obtain the median colour-z relations based on 74…
