Many of our Astro PhD students partake in other projects outside of their area of research. Ahlam Al Qasim (a 2nd year PhD student) and Aisha AlMannaei (a 1st year PhD student) are both working on Cubesat RAAD (Rapid Acquisition Atmospheric Detector), a mission recently funded by the UAE Space Agency through winning the Mini-satellite competition held last year. The competition was seeking out proposals from university students across the UAE for a science mission to be integrated on a Cubesat, with a launch opportunity in 2020. Their mission is aimed at studying the phenomenon of Terrestrial Gamma-Ray Flashes (TGFs), which are highly energetic events emitted via thundercloud activity in Earth’s atmosphere. Ahlam is the student PI of the science case and TGF simulations, and Aisha is the student PI for the detector development. Here, they discuss how the project was initiated and eventually extended to a fully funded mission, and what their current roles are.
Cosmic rays are rays of energetic particles and radiation, with their composition in our own Galaxy being dominated by protons. Ellis Owen, a final-year PhD student working on cosmic rays, star-formation and galaxy evolution, tells us about his research on them.
Every year in the Italian Alps, the renowned Tonale Cosmology Winter School takes place. This school brings together PhD students, Master’s students, and Post-docs in Cosmology from across the world, allowing them to share ideas and informing them of the state-of-the-art. One of our first year PhD’s, Anurag Deshpande, was fortunate enough to attend. He reports back on the school.
Not all PhD students join us directly after finishing their Master degree studies. Anurag Deshpande, a first year PhD student, spent a year working at the European Space Agency (ESA), as a Young Graduate Trainee (YGT). With the application process for the next round of YGTs now open, he discusses his time working on the James Webb Space Telescope, how he found the experience, and how it continues to influence him in his PhD research.
Cosmology is in pretty bad shape; we don’t know what makes up 95% of the Universe. Galaxies spin too fast and the expansion of the Universe is unexpectedly accelerating. Cosmologists deal with this by inferring the existence of dark matter and dark energy. These form the backbone of the Lambda Cold Dark Matter (LCDM) model. The problem is that we have no physical explanation for the existence of these two components.
You may be considering applying for a PhD at MSSL and want to know more about what it’s really like here. Some of our new students answer questions about how they are finding life as a research student here at the lab. Anurag, Choong Ling, and Nabil joined the Astrophysics group in this September.
The release of Gaia radial (line-of-sight) velocities in DR2 represents for me the first fruits of 17 years of work in the Gaia project. Such is the timescale of a mission as demanding, and different, as Gaia. I knew from the start, at mission adoption in 2001, that this would be a remarkable endeavour, not only from the scientific and technical perspective, but also from the long term working relationships and comradery that engaging deeply with it would entail.
