Subaru Telescope helps pinpoint origin of ultra-high energy neutrino

16.07.2018

Today, an international team announced that for the first time in the world they had identified the source object of an ultra-high energy neutrino.

On September 22, 2017 the IceCube experiment at Amundsen Scott station in Antarctica detected an ultra-high energy neutrino coming from outer space and was able to determine the direction it came from to within about 1 degree using the system developed by researchers at Chiba University.

While narrow compared to the entire sky, 1 degree still contains many possible candidates for the source object.

OISTER, a network of Japanese university telescopes, collaborating with the 8-m Subaru Telescope in Hawai?i, performed follow-up observations to determine the source of this enigmatic neutrino. They found that an object named TXS 0506+056 was acting peculiarly: shining 3 times brighter than normal and fluctuating more than usual.

TXS 0506+056 is a blazer, superheated matter releasing abundant radiation as it slowly spirals down into a supermassive black hole.

A quick calculation showed that the odds of two freak occurrences (the ultra-high energy neutrino and a flaring blazer) occurring so close together in time and space by pure chance is effectively zero, unless the two phenomena are related. Therefore TXS 0506+056 must be the source object of the neutrino.

Prof. Michitoshi Yoshida, the Director of Subaru Telescope comments, "We congratulate all members of the IceCube and OISTER teams on this important discovery.

We are proud that the Subaru Telescope with its deep observation capability could play a small role in this discovery. In this era of multi-messenger astronomy, collaboration between different observing facilities will be increasingly important. We look forward to working with this team more in the future."

Im Focus: The taming of the light screw

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.

The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a...

Im Focus: Magnetic micro-boats

Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.

The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...

Im Focus: Self-healing coating made of corn starch makes small scratches disappear through heat

Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.

Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...

Im Focus: Stellar cartography

The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.

A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...

Im Focus: Heading towards a tsunami of light

Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.

"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
