We use a recently released SDSS catalog of X-ray emitting AGNs in conjunction with the FIRST 20cm radio survey to investigate the black hole fundamental plane relationship between the 1.4GHz radio...
Thermal emission from warm dust in the most distant quasars (2008)
Wang, Ran, Carilli, Chris L., Wagg, Jeff, Bertoldi, Frank, Walter, Fabian, Menten, Karl M., ...
We report new continuum observations of 14 z~6 quasars at 250 GHz and 14 quasars at 1.4 GHz. We summarize all recent millimeter and radio observations of the sample of the 33 quasars known with...
Sharc-II 350 mm observations of thermal emission from warm dust in z >= 5 Quasars (2008)
Wang, Ran, Wagg, Jeff, Carilli, Chris L., Benford, Dominic J., Dowell, C. Darren, Bertoldi, Frank, ...
We present observations of four z >= 5 SDSS quasars at 350 mum with the SHARC-II bolometer camera on the Caltech Submillimeter Observatory. These are among the deepest observations that have been...

Millimeter and Radio Observations of z~6 Quasars (2007)
Wang, Ran, Carilli, Chris, Beelen, Alexandre, Bertoldi, Frank, Fan, Xiaohui, Walter, Fabian, ...
We present millimeter and radio observations of 13 SDSS quasars at reshifts z~6. We observed eleven of them with the Max-Planck Millimeter Bolometer Array (MAMBO-2) at the IRAM 30m-telescope at 250...
A search for HI 21cm absorption toward the highest redshift radio loud objects (2007)
Carilli, C. L., Wang, Ran, Van Hoven, M., Dwarakanath, K., Chengalur, J., Wyithe, S.
We have searched for HI 21cm absorption toward the two brightest radio AGN at high redshift, J0924--2201 at $z = 5.20$, and J0913+5919 at $z=5.11$, using the Giant Meter Wave Radio Telescope (GMRT)....

Wang, Ran, Wu, Xue-Bing, Kong, Min-Zhi
We derived the black hole fundamental plane relationship among the 1.4GHz radio luminosity (L_r), 0.1-2.4keV X-ray luminosity (L_X), and black hole mass (M) from a uniform broad line SDSS AGN sample...
Estimate black hole masses of AGNs using ultraviolet emission line properties (2005)
Kong, Min-Zhi, Wu, Xue-Bing, Wang, Ran, Han, Jin-Lin
Based on the measured sizes of broad line region of the reverberation-mapping AGN sample, two new empirical relations are introduced to estimate the central black hole masses of radio-loud...
