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.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
