Plasmonic Flat-Lens BES Helps Focus Light Into Nanoscale Colloidal Quantum Dot Photodetector

High-sensitivity photodetection is at the heart of many optoelectronic applications, including spectroscopy, imaging, surveillance, remote sensing and medical diagnostics. Achieving the highest possible sensitivity for a given photodetector technology requires the development of ultra-small-footprint detectors, as the noise sources scale with the volume of the semiconductor. This must be accomplished without sacrificing neither the optically active area of the detector nor its responsivity.

Astronomers Observe 'Fast Radio Burst’ as it Happens

A strange phenomenon has been observed by astronomers right as it was happening - a 'fast radio burst'. The eruption is described as an extremely short, sharp flash of radio waves from an unknown source in the universe. The results have been published in the Monthly Notices of the Royal Astronomical Society.

Principal Investigator of NuSTAR Awarded 2015 Rossi Prize in High-Energy Astrophysics

The 2015 Rossi Prize has been awarded to Fiona Harrison, a professor at the California Institute of Technology in Pasadena, California, for her "groundbreaking work on supernova remnants, neutron stars and black holes enabled by NuSTAR." NuSTAR is NASA's Nuclear Spectroscopic Telescope Array mission. The award, granted by the American Astronomical Society's High Energy Astrophysics Division (HEAD), is the top prize in high-energy astrophysics.

SLAC Staff Physicist Honored as Fellow of American Physical Society

SLAC staff physicist Peter Rowson has been elected a fellow of the American Physical Society, the largest physics association in the world. APS confers this distinction on a small percentage of the society’s membership; it is especially significant because it is a peer-nominated honor.

New Study on Anthropic Principle in Astrophysics and Particle Physics

For nearly half a century, theoretical physicists have made a series of discoveries that certain constants in fundamental physics seem extraordinarily fine-tuned to allow for the emergence of a life-enabling universe.

X-ray Image Shows Merger of Small, Compact Cluster with Large, Less Dense System

The catalogues of celestial objects contain a galaxy cluster called "Abell 4067". Recent observations with the XMM-Newton space observatory, however, reveal evidence that this object actually constitutes of the merger of two clusters. The smaller system appears to be losing the greater part of its gas.

Astronomers Look Back 13 Billion Years to Determine How Quasars Regulate Star Formation

Two teams of astronomers led by researchers at the University of Cambridge have looked back nearly 13 billion years, when the Universe was less than 10 percent its present age, to determine how quasars - extremely luminous objects powered by supermassive black holes with the mass of a billion suns - regulate the formation of stars and the build-up of the most massive galaxies.

Single Electrons Tunneling Through Quantum Dots Power Rice Grain-Sized Laser

Princeton University researchers have built a rice grain-sized laser powered by single electrons tunneling through artificial atoms known as quantum dots. The tiny microwave laser, or "maser," is a demonstration of the fundamental interactions between light and moving electrons.

Wavelength Electronics Introduces Quantum Cascade Laser LAB Family of Instruments

Electronic noise from Quantum Cascade Laser drivers has long limited the detection threshold of chemical sensors. No longer. Patented1 low noise technology is now available to both researchers and developers. Wavelength Electronics introduces the QCL LAB family of instruments that couple an intuitive touchscreen display with low noise drive electronics that have a proven track record of dropping detection thresholds up to an order of magnitude.

More Accurate Prediction of Distribution of Dark Matter Halos

Researchers at Kavli IPMU and their collaborators have revealed that considering environmental effects such as a gravitational tidal force spread over a scale much larger than a galaxy cluster is indispensable to explain the distribution and evolution of dark matter halos around galaxies. A detailed comparison between theory and simulations made this work possible.
