One of the powerhouse X-ray telescopes of our time, XMM-Newton, has just recently turned 20 years old. MSSL has been heavily involved in this mission. Sam Grafton-Waters, a third year PhD student at the lab use uses data from XMM to study active galactic nuclei, tells us more about this enduring satellite, and looks to the future.
WordPress.com is excited to announce our newest offering: a course just for beginning bloggers where you’ll learn everything you need to know about blogging from the most trusted experts in the industry. We have helped millions of blogs get up and running, we know what works, and we want you to to know everything we know. This course provides all the fundamental skills and inspiration you need to get your blog started, an interactive community forum, and content updated annually.
The distortion of the images of distant galaxies by the gravity of the large-scale structure of the Universe can be a powerful tool to help us understand our Universe. By measuring this distortion, known as cosmic shear, we can constrain cosmological parameters. However, in our analyses, we make certain approximations that may no longer be valid. Anurag Deshpande, a second-year PhD student tells us about two such effects; the reduced shear approximation and magnification bias.
It’s the time of year again when you may be considering applying for a PhD at MSSL. To give you a sense of what life is really like here, some of our new students will answer questions about how they are finding life as a research student here at the lab. Joana and Kaye joined the Astrophysics group earlier this year.
Get ready to witness a rare spectacle that won’t be seen for another 13 years as Mercury transits the Sun on 11th November 2019. But what is a transit, what is its scientific importance and how can you see it? Affelia Wibisono, PhD student, tells us more.
Dust is a very important element present everywhere in the Universe. In particular, dust attenuation absorbs, scatters and re-emits light. Nevertheless, not much is known on how dust affects light from galaxies at high redshift, since it is difficult to observe them. Mónica Tress, a final-year-PhD explains more about how dust attenuation effects are studied in galaxies far away.
After the first hugely successful meeting at UEA last year, this year UCL will host the 2nd meeting of the SPINS-UK Consortium. MSSL has a particularly strong involvement with this event: Prof. Silvia Zane is one of the scientific organisers, whilst postdoc Ziri Younsi along with PhD students Nabil Brice and Tom Kimpson all on the local organising committee. In addition to an extensive programme of scientific talks covering a range of neutron-star related science, there will also be discussion to address Brexit and the impact on scientific research and a public lecture (http://www.spins-uk.net/public-lecture.html) on gravitational waves by Prof. Alberto Vecchio of the University of Birmingham.
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.
