Talks from the Launch of new School of Physics and Astronomy

Launch of new School of Physics and Astronomy

Following the successfull Launch of new School of Physics and Astronomy that took place on Tuesday 31st January 2012, we have been asked to make available the summary of talks to all those who could not find place in the packed lecture hall.

Talks are listed in order of appearance, as listed in the official programme.

Leverhulme Trust Award

The School of Physics and Astronomy is pleased to announce that the Leverhulme Trust has awarded Queen Mary, University of London over £158,000 for a research project conducted by Dr David Tsikaluri.  The research project titled, Advanced model of solar radio bursts via plasma kinetic simulation, will run for three years.  

Solar activity directly affects humankind via hazardous for the terrestrial and space technology phenomena such as solar flares, coronal mass ejections, and solar energetic particle events. Better understanding of these phenomena will ultimately, enable humankind to predict and prepare for these hazards.

Objectives:

Astronomy PhD Positions Available

The Astronomy Unit has a number of funded PhD studentships available for UK, EU and International applicants. The deadline for applications is 31st January 2012 (although later applications may also be considered). Students will join an active research centre involved in a broad range of activities from cosmology to solar system science.  Full details are available on our web pages.

STFC Funded PhD Studentships

The Astronomy Unit has a number of STFC funded studentships available for start September 2012.

For application details see our PhD pages.

Exoplanet discovery

The recent discovery of a new exoplanet provides further evidence that cold Neptune-like bodies may not be that uncommon. The new exoplanet is called MOA-2009-BLG-266Lb, after the survey that first issued the alert, and is about ten times more massive than the Earth. It orbits a star with a mass of 0.56 Solar masses at a distance of 3.2 AU. The planet's mass and distance indicate that it may be a "failed Jupiter-core" since current planetary formation theories predict that an object of such characteristics should have swept up the surrounding gas and grown more massive.

ESA Selects Solar Orbiter Mission

The ESA Science Programme Committee has selected Solar Orbiter as the M1 Medium Class mission in its Cosmic Vision programme, with a 2017 launch. Solar Orbiter will get closer to the Sun than any previous mission in order to study the coronal source regions of the solar wind and its in situ evolution. David Burgess, of the Astronomy Unit, is a member of the Science Teams for three different instruments: the magnetometer, solar wind particle analyser and plasma wave instrument. 

In addition to Solar Orbiter, ESA has selected Euclid, a cosmology mission targeted at dark matter and dark energy, for a 2019 launch.

PhD Viva: Heidar Thrastarson

Congratulations to Heidar Thrastarson on the successful passing of his PhD viva on 19 September! His thesis is entitled: "General Circulation Modelling of Close-In Extrasolar Giant Planets."

The figure shows dynamic, planetary scale storms on a Hot Jupiter, with instantaneous flow (arrows) and potential vorticity (colour scale) in a simulation of a typical close-in extrasolar giant planet atmosphere.
