Group Blog

Hi, readers. I am Doosoo Yoon, who recently has joined Sera’s group. Since I started my academic career in astronomy, I have strongly interested in performing numerical simulations to figure out how astrophysical phenomena can be interpreted. In my first post, I would like to briefly talk about some basic processes of computational astrophysics and […]

Given that our group has been growing significantly over the last years, annual group retreats are the ideal occasion to get to know each other better and talk about important topics that don’t necessarily find their way in usual working days. So, just recently, we spent a whole day at a beautiful little farm in

Supermassive black holes are powerful engines. A black hole with the mass of a million-10 billion times the mass of the Sun is fueled by gas surrounding it. A small fraction of these systems accelerate particles in a collimated outflow of plasma, called jet. Many questions about AGN jets remain unanswered: How are those jets

The first paper of my PhD thesis was accepted on Friday for publication on Monthly Notices of the Royal Astronomical Society, and it was posted on arXiv yesterday! If you’re interested in jets and how to be clever with data to learn more about them, check it out! https://arxiv.org/abs/1810.11341

For this blog I thought I would talk a bit about my favourite telescope (yes, I have one of those…). As Dimitris talked about last week, detecting high-energy radiation can be complicated. X-rays for example are blocked by the atmosphere, so if you want to look at astronomical sources emitting X-rays you need to put

or How to detect high energy γ rays   Radiation is being produced all over the universe. This radiation can either be observed by detectors on the surface of the Earth or be absorbed by the atmosphere. As Figure 1 demonstrates, radiation at radio wavelengths and visible light can reach the terrestrial observatories located around

This week we have had an exciting new result published in Nature. This was work led by Jakob van den Eijnden, a PhD student here at in Amsterdam, and included his advisor Nathalie Degenaar, myself, Rudy Wijnands and Juan Hernandez-Santisteban here in Amsterdam, as well as James Miller-Jones (ICRAR/Curtin University, Australia) and Greg Sivakoff (University of

In this blog-post, I want to share my experience in the field of science communication and give you my personal perspective of things. I would be very happy to receive your feedback. Maybe, you disagree with what I say? Maybe, I missed something in my discussion? Feel free to contact me ([email protected]) or post a

As this picture shows, nothing seems to make members of my group happier than a massive rack of ribs (well except for me and Atul, who are eating the veggie options…). That, and a visit from our collaborator Sasha Tchekhovskoy, from Northwestern University! (left to right: me, Koushik Chatterjee, Prof. Sasha Tchekhovskoy, Dr. Gibwa Musoke,

Hi again, I thought now might be a good time to highlight some of the other work that we get to do (using one of my programs as an example, but almost all of us here at API do something similar, or even better). Work that isn’t sitting at a computer analysing data or writing
