Dear all,
The first STRW/SRON Galaxy Cluster Seminar for 2026 is scheduled for next Thursday, January 15th, at 13:00. This time we have a remote speaker, Jakob Dietl, from the University of Bonn and the group of Thomas Reiprich. The title of the talk is:
Individual Cosmic Filaments with eROSITA and Machine Learning Detection of Galaxy Clusters
while the abstract can be found at the end of this email. The seminar will take place through zoom (the link will be shared on the previous day), but attendees will also gather in CE.0.18 if they like, like an in-person cluster seminar, to attend the talk together.
We hope to see you all there.
Cheers, Kostas & Joshiwa
Abstract: The SRG/eROSITA mission is providing an unprecedented X-ray view of large-scale structure in the Universe, allowing detailed studies of galaxy cluster outskirts, cluster-cluster bridges and X-ray-emitting filaments. In the first part of the talk, I will show examples of eROSITA-detected large-scale structures, focusing mainly on analyses of the A3667/51 system and the outskirts of A3266. Recent comparisons with predictions from the SLOW simulation identified two additional systems with potential large-scale filaments. In the second part, I will present current machine-learning efforts for galaxy cluster detection in eROSITA data, highlighting the importance of large multi-wavelength surveys for AI research in astrophysics.
Dear all,
This is a friendly reminder for our Galaxy Cluster Seminar tomorrow at 13:00, (remotely) hosting Jakob Dietl from the University of Bonn, who will talk about:
Individual Cosmic Filaments with eROSITA and Machine Learning Detection of Galaxy Clusters
The abstract can be found in the original email from last Friday.
The zoom link for the talk is:
https://universiteitleiden.zoom.us/j/68988974200?pwd=7KegiebdaXRTqVdqkCYbcsb...
For anyone interested, we will also gather in the CE.0.18 room at 13:00 to attend the talk together, aiming for a more lively discussion.
Cheers, Kostas & Joshiwa
