TL;DR: In this paper, the results of spectroscopic studies with the LRIS spectrograph on Keck of two of the Hawaii deep survey fields were presented, and the evolution of the rest-frame K-band luminosity function and its evolution with redshift were described.

TL;DR: In this article, the authors presented point-source catalogs for the 2Ms exposure of the Chandra Deep Field North, currently the deepest X-ray observation of the universe in the 0.5?8.0 keV band.

TL;DR: In this article, a deep survey of two blank regions of sky performed at sub-millimeter wavelengths (450 and 850-micron) was performed, and it was shown that if the sources detected in the 850micron band are powered by star formation, then each must be converting more than 100 solar masses of gas per year into stars, which is larger than the maximum star formation rates inferred for most optically selected galaxies.

TL;DR: A deep survey using the Chandra satellite detects hard X-ray sources that could be active nuclei in dust-enshrouded galaxies or a population of quasars at extremely high redshift.

TL;DR: In this paper, the authors used highly spectroscopically complete deep and wide-area Chandra surveys to determine the cosmic evolution of hard X-ray-selected active galactic nuclei (AGNs).
