I am delighted to have started this week as a Feodor Lynen Fellow of the Alexander von Humboldt Foundation (@humboldt-foundation.de) at the Donostia International Physics Centre (@dipcehu.bsky.social) in San Sebastián, working in Raúl Angulo's group.

How does dynamical friction change when dark matter has self-interactions? Learn about it in our new paper by Laura Sagunski and myself. https://arxiv.org/abs/2405.19392

Just compiled a plot of various constraints on the dark matter self-interaction cross-section for my upcoming talks.

Two and four weeks ago, two papers appeared on arXiv investigating numerical problems in N-body simulations of collapsing SIDM halos. We join them with our study explaining the causes of energy conservation errors in simulations of the late collapse phase. https://arxiv.org/abs/2403.00739

I am honoured to have received the Best Paper Award from the Cluster of Excellence Quantum Universe today. https://www.qu.uni-hamburg.de/research/highlights/23-04-18-fischer.html

Our new website for our research on self-interacting dark matter is online. Check it out! https://darkium.org

Paper day! We have studied the role of the ICM in merging galaxy clusters with SIDM: 1. the presence of the ICM enhances DM-galaxy offset, 2. the position of the shock front combined with the galaxy positions could be an interesting probe of DM. https://arxiv.org/abs/2302.07882
