What the Propagation of Energetic Light can Tell us about the Evolution of Stars, Intergalactic Magnetic Fields and Fundamental Physics

Written by: Jonathan Biteau and Manuel Meyer Photons at energies beyond a billion times that of X-rays cannot reach us from the outer edges of the observable Universe. Only a fraction of these very-high-energy gamma rays reach our atmosphere to produce firework-like visual displays called air showers. While our eyes can’t see these rapid air ganzen Artikel lesen...

Schwarzschild-Couder Telescope Prototype Primary Mirror Installation Complete

The prototype Schwarzschild-Couder Telescope (pSCT), under construction at the Whipple Observatory in Arizona, completed its primary mirror installation on 26 April 2018 (watch the construction on the live webcam). The primary mirror consists of 48 mirror panel modules each including ~1m2 aspheric mirror integrated with six actuators and four/five edge sensors for mirror positioning and ganzen Artikel lesen...

LST Prototype Sheds Icy Shell Before Structure Completion

Things got a bit icy at the Roque de los Muchachos earlier this month! During the second week of February, a bad cold weather front with strong winds, low temperatures and rain hit the island of La Palma. Once the storm passed and the clouds cleared, spectacular ice formations were left behind. The Large-Sized Telescope ganzen Artikel lesen...

CTA in the Era of Multi-Messenger Astrophysics

Written by: Fabian Schüssler After years of preparation, a fundamentally new domain of astronomy and astrophysics has shown its first results: multi-messenger astrophysics. Throughout the past decade, several new astrophysical messengers have provided us with new insights into the most violent phenomena in the Universe: starting with high-energy gamma rays, the detection of an astrophysical ganzen Artikel lesen...

The LST Prototype’s Dish is Mounted

On 4 December, The LST prototype, under construction at Roque de los Muchachos Observatory in La Palma, reached an important milestone when its 18-ton mirror dish, mostly made of reinforced carbon fiber tubes, was lifted to the lower structure successfully. After careful preparation, the dish was lifted 18 meters above the ground and secured using ganzen Artikel lesen...

La Palma Consortium Meeting Wrap-up

Written by: Jürgen Knödlseder, Chair, CTA Consortium Board During the week of 6 November, 230 CTA Consortium members gathered on the beautiful island of La Palma (Spain) for its bi-annual, in-person meeting.   Topics covered during the parallel and plenary sessions of the meeting included progress reports on the CTA prototypes, the Science Working Groups ganzen Artikel lesen...

Medium-Sized Telescope Prototype Records First Cherenkov Light with the FlashCam Camera

In September 2018, the Medium-Sized Telescope structure (MST-STR) and FlashCam teams started a joint test campaign in Berlin-Adlershof that resulted in the capture of the MST prototype’s first Cherenkov light. The integration of the camera with the telescope structure took place on 18 September. Thanks to advanced planning, the teams quickly completed the next steps ganzen Artikel lesen...

Hadrons or Leptons? That is the question!

Written by Fabrizio Tavecchio & Stefano Vercellone This Chandra image of the nearby galaxy Centaurus A provides one of the best views to date of the effects of an active supermassive black hole. Opposing jets of high-energy particles can be seen extending to the outer reaches of the galaxy. Image credit: NASA/CXC/CfA. Extragalactic (from outside ganzen Artikel lesen...
