A technique to measure mechanical motion beyond the quantum limit

Researchers at the University of Colorado have recently developed a new technique to measure mechanical motion using simultaneous electromechanical amplification and cooling processes. Their method, presented in a paper published in Physical Review Letters, allowed them to perform a nearly noiseless measurement of the position of a mechanical oscillator, which has so far proved to be difficult using alternative techniques for measuring motion.

Researchers substantially boost sensitivity of terahertz gas analysis

A new advance promises to increase the sensitivity of high-resolution spectrometers that perform chemical analysis using terahertz wavelengths. This higher sensitivity could benefit many applications, such as analysis of the complex gas mixtures found in industrial emissions and detection of biomarkers of disease in the breath of patients. It could also lead to new ways to detect food spoilage through gas detection.

New water-based optical device revolutionizes the field of optics research

Light is versatile in nature. In other words, it shows different characteristics when traveling through different types of materials. This property has been explored with various technologies, but the way in which light interacts with materials needs to be manipulated to get the desired effect. This is done using special devices called light modulators, which have the ability to modify the properties of light.

First detection of the cosmic monster explosions with ground-based gamma-ray telescopes

The strongest explosions in the universe produce even more energetic radiation than previously known: Using specialized telescopes, two international teams have registered the highest energy gamma rays ever measured from so-called gamma-ray bursts, reaching about 100 billion times as much energy as visible light. The scientists of the H.E.S.S. and MAGIC telescopes present their observations in independent publications in the journal Nature. These are the first detections of gamma-ray bursts with ground-based gamma-ray telescopes. DESY plays a major role in both observatories, which are operated under the leadership of the Max Planck Society.

The Large Synoptic Survey Telescope could find more of Earth's transient moons

It is a well-known astronomical convention that Earth has only one natural satellite, which is known (somewhat uncreatively) as "the moon." However, astronomers have known for a little over a decade that Earth also has a population of what are known as "transient moons." These are a subset of near-Earth objects (NEOs) that are temporarily scooped up by Earth's gravity and assume orbits around our planet.

Spain has permits to build giant telescope blocked in Hawaii

The director of a Spanish research center said Wednesday that a giant telescope, costing $1.4 billion, is one step nearer to being built on the Canary Islands in the event an international consortium gives up its plans to build it in Hawaii.

Breaking the limits: Discovery of the highest-energy photons from a gamma-ray burst

Gamma-ray bursts (GRBs) are brief and extremely powerful cosmic explosions, suddenly appearing in the sky, about once per day. They are thought to result from the collapse of massive stars or the merging of neutron stars in distant galaxies. They commence with an initial, very bright flash, called the prompt emission, with a duration ranging from a fraction of a second to hundreds of seconds. The prompt emission is accompanied by the so-called afterglow, a less brighter but longer-lasting emission over a broad range of wavelengths that fades with time. The first GRB detected by the MAGIC telescopes, known as GRB 190114C, reveals for the first time the highest energy photons measured from these objects.
