Hard X-rays, tough stuff

Here's my latest story, just came out today... the topic's pretty technical but I hope I managed to break it down to the basics. Let's see: essentially, a satellite named INTEGRAL is surveying the sky seeking very high-energy photons (in this case, so-called hard x-rays) coming from a series of objects throughout our own Galaxy and from far away galaxies as well. Now, a new method has been developed to make it work even better.

For those (possibly!!) interested in further details... enjoy :-)

INTEGRAL completes the deepest all-sky survey in hard X-rays

A newly developed image analysis technique has significantly improved the sensitivity limits reached by the IBIS imager on board INTEGRAL, resulting in the deepest survey ever compiled of the entire sky in the energy range between 17 and 60 keV. Pushing the instrument towards its very limits, the novel method discloses a vast number of previously undetected faint sources, galactic and extragalactic alike. More...
