The 2 Ms Chandra Deep Field-North survey provides the deepest view of the Universe in the 0.5–8.0 keV X-ray band. In this brief review we investigate the diversity of X-ray selected sources and focus on the constraints placed on AGNs (including binary AGNs) in high-redshift submm galaxies.

WIMP-nucleon cross sections σ ∼ < 10 −9 pb may be probed by ton-scale experiments with low thresholds and background rates ∼ 20 events per year. An array of cryogenic detectors (" CryoArray ") could perform well enough to reach this goal. Sufficient discrimination and background suppression of photons has already been demonstrated. Reduction of neutron backgrounds may be achieved by siting the ...

IceCube is a kilometer scale neutrino observatory now in construction at the South Pole. The construction started in January 2005 with the deployment of 76 sensors on the first string and four surface detector stations. Nine strings and 32 surface detectors are in operation since February 2006. The data based on calibration measurements , muons and artificial light flashes are consistent with p...

We present the results of a search for high energy extraterrestrial neutrinos with the Baikal underwater Cherenkov detector NT200, based on data taken in 1998 2003. Upper limits on the diffuse fluxes of νe + νμ + ντ , predicted by several models of AGN-like neutrino sources, are derived. For an E−2 behavior of the neutrino Preprint submitted to Elsevier Science 5 February 2008 spectrum, our lim...
