Images from NASAs new Spitzer Space Telescope have allowed researchers to detect the long sought population of "missing" supermassive black holes that powered the bright cores of the earliest active galaxies in the young universe. The discovery completes a full accounting of all the X-ray sources seen in one of the deepest surveys of the universe ever taken. The results were presented at the meeting of the American Astronomical Society in Denver, Colorado.
Mark Dickinson, of the National Optical Astronomy Observatory in Tucson, Ariz., and Principal Investigator for the new observations, says, "With these ultra-deep Spitzer images, we are easily seeing objects throughout time and space, out to redshifts of 6 or more, where the most distant known galaxies lie. Moreover, we see some objects that are completely invisible to optical telescopes, but whose existence was hinted at by previous observations from the Chandra and Hubble Observatories."
The project combined the power of NASAs three Great Observatories in space - the Hubble Space Telescope (HST), the Chandra X-ray Observatory, and the Spitzer Space Telescope (SST). All three telescopes peered across 13 billion light-years of space into a small region of dark sky (called the Great Observatories Origins Deep Survey, GOODS) that is ideal for perusing thousands of galaxies.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
