Life Out There with Dr. Sergey Yurchenko

By | Satellites and space | No Comments

Is there life out there? If so, what does that mean for us? Can they see us?  Timothy Metcalf (SES Consortium Manager) sits down with Dr. Sergey Yurchenko (Senior Lecturer, UCL Physics and Astronomy) to talk about his research into Exoplanets as part of the Exomol group. Using SES HPC machine Emerald, Dr. Yurchenko and his team of scientists analyse large quantities of space data from telescopes such as Hubble to help determine where we may be able to find inhabitable planets in outer space. To find out more about Prof. Yurchenko’s work, read the case study and stay tuned…

HPC Adds Extra Dimension To The Search For Extraterrestrial Life

By | Popular, Satellites and space, Uncategorised | No Comments
The SES consortium’s Emerald supercomputer is providing UCL astrophysicists with the computing firepower they need to help pinpoint exoplanets capable of supporting alien lifeforms. Unarguably, it is one of the biggest scientific and philosophical questions of all: are we alone in the universe? In the quest for an answer, one of the most important developments in recent decades has been the ability to detect planets circling distant stars. Once such an ‘exoplanet’ has been discovered – and around 2000 have been identified so far – a key step is to establish whether its atmosphere is potentially conducive to supporting life...

Observational signature of co-rotating spiral arms

By | Satellites and space | No Comments
The spiral arm seen in disk galaxies have fascinated generations, and their nature and origin are still unknown. Since the 1960s, the most accepted explanation of spiral arms has been the density wave theory, in which spiral arms rotate around galaxy like a Mexican wave in a stadium crowd, passing through stars. The theory thus predicts long-lived spiral arms. However even the most recent high-resolution numerical simulations cannot create the type of long-lived spiral arms expected from density-wave theory – instead transient and recurrent arms are found. Our recent studies showed that this happens because the spiral arms rotate at the...

Working towards the Square Kilometre Array

The Many-cOre Technology Investigating Value, Application, deploymenT and Efficiency project or (MOTIVATE for short); is a pathfinder project with the aim of investigating the application of the latest many-core technologies, such as GPUs, to deliver energy and cost efficiencies in the area of radio astronomy High Performance Computing. Astrophysical radio sources such as Pulsars are excellent probes of extreme physical processes originating from compact sources within our Galaxy and beyond. Generating intermittent radio bursts of milliseconds in duration, as observed here on earth, the signals generated by Pulsars carry valuable information about the physical processes occurring at the source as well as in the intervening interstellar or intergalactic...
