Observational constraints on the co-evolution of supermassive black holes and galaxies (2009)
Zheng, X. Z., Bell, E. F., Somerville, R. S., Jahnke, K., Fontanot, F., ...
The star formation rate (SFR) and black hole accretion rate (BHAR) functions are measured to be proportional to each other at z < ~3. This close correspondence between SF and BHA would naturally...
Greve, T. R., Weiss, A., Walter, F., Smail, I., Zheng, X. Z., Knudsen, K. K., ...
Using the 330hr ESO-MPG 870-micron survey of the Extended Chandra Deep Field South (ECDF-S) obtained with the Large Apex BOlometer CAmera (LABOCA) on the Atacama Pathfinder EXperiment (APEX), we have...

Multiwavelength Observations of one Galaxy in Marano Field (2005)
Liang, Y. C., Hammer, F., Flores, H., Elbaz, D., Deng, L. C., Assemat, F., ...
We report the multiwavelength observations of one intermediate redshift (z=0.3884) galaxy in the Marano Field. These data include ISOCAM middle infrared, VLT/FORS2 spectroscopic and photometric data,...
HST/WFPC2 morphologies and bar structures of field galaxies at 0.4 (2005)
Zheng, X. Z., Hammer, F., Flores, H., Assemat, F., Rawat, A.
To address how the galaxy Hubble sequence is established and what physical processes are involved, we studied morphological properties and internal structures of field galaxies in the past (0.4
Hammer, F., Flores, H., Elbaz, D., Zheng, X. Z., Liang, Y. C., Cesarsky, C.
Studies of distant galaxies have shown that ellipticals and large spirals (Schade et al. \cite{Schade99}, ApJ, 525, 31; Lilly et al. \cite{Lilly98}, ApJ, 500, 75) were already in place 8 Gyr ago,...
HST/WFPC2 morphologies and bar structures of field galaxies at 0.4 < z < 1 (2005)
Zheng, X. Z., Hammer, F., Flores, H., Assémat, F., Rawat, A.
To address how the galaxy Hubble sequence is established and what physical processes are involved, we studied morphological properties and internal structures of field galaxies in the past (0.4
A recent rebuilding of most spirals ? (2004)
Hammer, F., Flores, H., Zheng, X. Z., Liang, Y.
Re-examination of the properties of distant galaxies leads to the evidence that most present-day spirals have built up half of their stellar masses during the last 8 Gyr, mostly during several...
Hammer, F., Flores, H., Elbaz, D., Zheng, X. Z., Liang, Y. C., Cesarsky, C.
(abridged) Studies of distant galaxies have shown that ellipticals and large spirals were already in place 8 Gyr ago, leading to a very modest recent star formation in intermediate mass galaxies....
HST/WFPC2 morphologies and color maps of distant luminous infrared galaxies (2004)
Zheng, X. Z., Hammer, F., Flores, H., Assemat, F., Pelat, D.
Using HST/WFPC2 imaging in F606W (or F450W) and F814W filters, we obtained the color maps in observed frame for 36 distant (0.4
Xu, D. W., Komossa, Stefanie, Wei, J. Y., Qian, Y., Zheng, X. Z.
This work studies the optical emission line properties of a sample of 155 low-redshift bright X-ray selected ROSAT Seyfert~1 type AGN for which adequate signal-to-noise ratio spectroscopic...
Spectroscopic Properties of QSOs Selected from Ultraluminous Infrared Galaxy Samples (2002)
Zheng, X. Z., Xia, X. Y., Mao, S., Wu, H., Deng, Z. G.
We performed spectroscopic observations for a large infrared QSO sample with a total of 25 objects. The sample was compiled from the QDOT redshift survey, the 1 Jy ULIRGs survey and a sample obtained...
