The Sources of the CDF-N : broadband spectral analyses, absorption measurements and the alpha_ox - L_UV relation
S. Frank, Patrick S. Osmer, S. Mathur
We present broadband properties of sources in the Chandra Deep Field-North with spectroscopic redshifts. The high luminosity and redshift bins are dominated by typical quasars. The…
The Evolution of Quasars
Patrick S. Osmer
This article reviews and discusses 1) the discovery and early work on the evolution of quasars and AGNs, 2) the different techniques used to find quasars and their suitability for…
Searches for Quasars at z > 5
Patrick S. Osmer
Quasars continue to be the most luminous objects known in the universe but are now rivaled by galaxies for having the largest redshifts. I review current techniques for finding qua…
A Review of Line and Continuum Correlations in AGNs
Patrick S. Osmer, Joseph C. Shields
This review addresses the current observational status of the Baldwin Effect (BE), an empirical anti-correlation between emission line equivalent width and source luminosity for ac…
The Evolution of Quasars at High Redshift and Their Connection with Galaxies
Patrick S. Osmer
I review recent observations on the evolution of quasars, describe new surveys for quasars at z > 5 and for quasars at z > 3.3 down to luminosities corresponding to L* galaxies, an…
THE CLUSTERING OF QUASARS
P. Andreani, S. Cristiani, F. La Franca
We have investigated the spatial distribution of quasars and its relationship with redshift by using the two-point correlation function, the variance of cell counts and the conditi…
