AHPC activities

This Researcher's Night, the AHPC group's Scientists - experts in Astrophysics and Computer Science - will engage the public in a series of interactive sessions based on exciting facts relating to the Universe, astronomy and the modern methods of research we use to conduct our work, including High Performance Computing (parallel programming). The content of the activities will be adjusted according to individual’s background knowledge, with activities suitable for all ages from children to adults. Below one can find more details and information about the activities we will have on offer.

An image by Herschel of thousands of distant galaxies, in a patch of sky called GOODS-North, In the constellation of Ursa Major. The image is half a degree across - about the size of the Full Moon and was made from the three SPIRE bands: 500 µm (red), 350 µm (green) and 250 µm (blue).

The HELP fields, pictured with white boundary regions, cover over 1000 deg2 of the whole sky, which is illustrated by the Planck thermal dust emission map. The galactic plane, as the closest dust emission source to us, lies along the red/yellow shaded area.

The COSMOS field with six galaxies picked out. For each of the six, its appearance in visible light is shown (Hubble Space Telescope), along with a spectrum (10m W.M. Keck telescope), along with the time the light has been travelling for.

Scale your Cosmos Right!

  • Webpage by Dr. Jen Gupta (ICG; University of Portsmouth)
  • A twist on the classic TV gameshow ‘Play Your Cards Right‘. The game is pretty simple: Six cards are set out face down. The player then turns over one card after the other and each time the player has to sort the astronomical objects based on their actual size!

Chat with an Astronomer

  • Chat with our researchers on various astronomical subjects and recent research updates from our group.

High Performance Computing

  • By using a laptop and a wireless connection to High Performance Computing machines (Supercomputers) our researchers will engage the public through live performance comparisons of serial and parallel algorithms. Using the guidance of our researchers, the public will be able to develop and test simple parallel and serial algorithms in real time, using a Supercomputer.
