SALT tests cosmic ruler

Published

The Southern African Large Telescope (SALT) in Sutherland has begun testing a Laser Frequency Comb, a device that uses powerful lasers and photonic crystal fibres to produce the equivalent of a ruler that is both extremely long and has very finely spaced graduations.

The Southern African Large Telescope (SALT) in Sutherland has begun testing a Laser Frequency Comb,  a calibration device that uses powerful lasers and photonic crystal fibres to produce the equivalent of a ruler that is both extremely long and has very finely spaced graduations. The pioneers of this decade old technology were awarded the Nobel Prize in Physics in 2005.

A team of laser physicists from the Heriot-Watt University, Derryck Reid and Richard McCracken, along with astronomers from SALT and South African Astronomical Observatory (SAAO), Éric Depagne, Rudi Kuhn, Nicolas Erasmus and Lisa Crause, installed the Laser Frequency Comb device on the SALT’s High Resolution Spectrograph (HRS) to perform the first routine comb-enabled scientific observations on a 10m-class telescope.

“The Laser Frequency Comb is a significant improvement in the way astronomers will calibrate their spectra in the future”, says Éric Depagne, project leader and HRS Instrument scientist. “It allows reaching much higher accuracies when measuring radial velocities, while adding something that is completely missing when using standard calibration sources – traceability. Since the electronic components and the optical devices are all linked to calibrated atomic clocks, we are sure that if we repeat the measurements in 20 years, they will be comparable to those we do today. And that is something fundamentally new”.

Professor Derryck Reid from Heriot-Watt University said: “We’ve been developing the Laser Frequency Comb at Heriot-Watt University for 10 years and to finally demonstrate it on the SALT telescope is really exciting. Its accuracy and precision allows astronomers to derive precise fundamental parameters for a wide range of astronomical objects, from the existence of planets around distant stars, to the determination of the variability of the first generation of stars and the measurements of isotopic ratios that provide detailed information on the nature of supernovae”.

Astronomers determine the composition of stars by using spectrographs to split the light into various colours, exactly like water droplets produce rainbows when it rains. Each element we know in the Universe has a unique signature. Sodium, for instance produces bright yellow light, Neon glows red, and Magnesium has a blueish hue. By identifying the individual signatures of elements in the spectra of celestial objects, astronomers can infer the chemical composition, and many more parameters, such as the speed at which objects move relative to the earth, their temperature, and their mass.

In certain studies, astronomers must look for small changes in the colour of light emitted by stars. For example, the gravitational pull of a planet orbiting a star imprints a tiny wobble on the star, causing the colour of the star’s light to fluctuate by a small amount. As astronomers search for smaller, more “Earth-like” planets they need better tools with which to measure these tiny fluctuations. The Laser Frequency Comb could provide the precision measurement capability which is needed for this exciting new science.

Huawei goes ultra-premium

Porsche Design and Huawei have launched the Porsche Design Huawei Mate RS in South Africa exclusive to MTN and retailing for R 26 459.

Published

on

The Porsche Design Huawei Mate RS boasts features like the world’s first dual fingerprint design, including an in-screen fingerprint sensor, the world’s first Artificial Intelligence (AI) processor and Leica triple camera with 40MP image capture.

“After the overwhelming success of the Porsche Design Huawei Mate 10 Pro in South Africa, we now bring you our latest offering, a perfect blend of innovation in a smartphone and luxury design,” said Likun Zhao, Vice President of Huawei Consumer Business Group Southern Africa. “From three-point security feature including facial recognition, rear fingerprint scanner and the new innovative in-screen fingerprint to the Leica triple camera system. it culminates in an unprecedented experience for our customers.”

The device incorporates Porsche Design’s signature design language and Huawei’s breakthrough technology.  The phone has a 6” 2K curved OLED screen and symmetrical look, minimalist feel and 8-edged 3D curved glass body.

High performance is symbolised by the naming of the smartphone: the term “RS” in the world of Porsche motorsport stands for outstanding racing performance.

Huawei provided the following information on The Porsche Design Huawei Mate RS benefits and features :

·         The world’s first dual fingerprint scanner for enhanced convenience, allowing users to wake and unlock the device simply, thanks to an in-screen fingerprint sensor. Hover to wake the device, touch to unlock it

·         The winning combination of Leica triple camera with 40MP RGB sensor technology and exceptional photography powered by Master AI. This combination puts effortless, eye-catching photography at the fingertips of those looking to immortalise their favourite moments. Combined with 5 x hybrid zoom, and the world’s first AI image stabilisation on a smartphone camera ensures photography lovers can capture the best shots with exceptional clarity in almost any situation

·         The Porsche Design Huawei Mate RS is the first Huawei handset to allow quick wireless charging, making it even easier to keep the phone topped up and ready to go and, thanks to its long lasting battery, users will easily be powered through the busiest of days

·         An ‘intelligent’ smartphone, the powerful AI processor automatically tailors the performance of the phone according to how it is used – constantly learning, understanding and anticipating needs, it is the perfect personal assistant for the pocket

·         256GB of internal storage means those constantly on the go and constantly on their phone can be worry free

·         Dual SLS (super linear system) speakers with DOLBY ATMOS enable users to have a superior experience, with the best immersive surround sound and entertainment on the go

·         Splash, water and dust resistant, which means there is no need to worry about damaging the device in the rain or accidentally dropping it in water

Jan Becker, CEO Porsche Design Group, said: “Both Porsche Design and Huawei seek to imagine and develop products that stand for precision and perfection, intelligent functionality and highly sophisticated design. Our aim was to create an outstanding device that goes one step further. We believe we have reached this goal by taking our partnership to the next level.”

Porsche Design and Huawei have worked in tandem to develop a smartphone that fuses together the two brands’ DNA, wealth of experience in design and technology, industry-leading expertise and exceptional performance. Through the use of colour in the device’s body, software themes and accessories, the new handset is accentuated with Porsche Design’s distinguished aesthetic and purist, minimalist feel.

The Porsche Design Huawei Mate RS will be available to purchase exclusively from MTN at R 26 459.
