• epp team members contribute to solve mystery of why comets emit X-rays

    The mystery of X-ray emissions from comets has been solved by an international team integrating epp team researchers, Fabio C and Luis OS. This work was published today in Nature Physics.
    Scientists have long wondered why comets can radiate X-rays, given that X-rays are normally associated with hot objects like the Sun but comets are among the coldest objects in the Solar system.
    When comets travel through the Solar system they interact with the Solar radiation, the Solar wind and the Solar magnetic field. This produces a visible atmosphere (or coma), the characteristic cometary tail, and in some cases X-rays. These X-rays are generated on the sunward side of the comet where the Solar wind impacts the cometary atmosphere forming a bow shock.
    To investigate how the X-rays are generated, an international team of scientists from 15 institutes performed experiments using the ultra-intense lasers available at the LULI facility in Paris,…

  • The “Natas” of Visualization 2017 have been announced!

    And they are “tasty”! Following our tradition (see News for the “2014 Natas”News for the “2015 Natas”, News for the “2016 Natas”), the prizes for the winners of the image and video of 2017, the “natas” of visualization, were awarded to Fabio Cruz (left, and triple winner after wins in 2014 and 2016) and to Fabrizio Del Gaudio (right). The term “Nata” was coined by one of the previous winners Paulo Alves: “Nata” is a tasty Portuguese pastry that everybody likes. It’s as enjoyable as having our simulations running nicely on a big supercomputer. It can also mean being at the top, at a high level, important.” Many congratulations to the 2017 winners! The images and videos will be posted on the team website and over the next few weeks on GoLP’s Facebook page.

  • EuPRAXIA at IST

    The 2nd EuPRAXIA Yearly meeting, held from November 20 to November 24 2017, was hosted at IST and organised by GoLP. This meeting gathered more than 80 participants coming from several European Countries. The goal of this project is to produce a conceptual design report for the worldwide first high energy plasma-based accelerator that can provide industrial beam quality and user areas (more information here). ​The Portuguese participation in the EuPRAXIA project is provided by GoLP. The EuPRAXIA is a project funded by the EU. The EuPRAXIA yearly meeting at IST was sponsored by IST and CGD.
