Alright, we’re out of here. This platform and the recents comments by its owner have become too problematic. In fact, we should have left some time ago. You will find us on LinkedIn. See ya.
New simulations of magnetic fields in neutron stars just dropped. Delayed jet launching in binary neutron star mergers with realistic initial magnetic fields led by our postdoc R. Aguilera-Miret.
arxiv.org/abs/2407.20335
Today on arxiv: Probing the Magnetised Gas Distribution in Galaxy Groups and the Cosmic Web with #POSSUM Faraday Rotation Measures led vy C. Anderson.

Hamburg is shaking it off! ✨Diese Woche gibt Taylor Swift zwei Konzerte im Hamburger Volkspark. Seismische Wellen, die dabei entstehen nimmt auch die Geophysik der Uni Hamburg genauer unter die Lupe: uni-hamburg.de/newsroom/pres…
Machine learning can help extract information about magnetic fields in radio observations: Semi-Supervised Rotation Measure Deconvolution and its application to #MeerKAT observations of galaxy clusters led by our student V. Gustafsson with @TorstenEnsslin arxiv.org/abs/2407.16762
Popular science article on S. Rosswog’s ERC grant on colliding neutron star, gravitational waves and flashes came out here: edition.pagesuite.com/html5/… @UHHMIN
Out today: Zooming in on the Circumgalactic Medium with GIBLE: Tracing the Origin and Evolution of Cold Clouds led by R. Ramesh with @DrummondBField et al. Cold clouds do not live very long & collective cloud-cloud dynamics is crucial to their evolution. arxiv.org/abs/2407.00172
Out today: Ultra-low frequency @LOFAR spectral indices of cluster radio halos led by @ThomasPasini94 w @roxycas @and_botteon @hen_edler et al. Main result: more massive clusters host flatter-spectrum halos
arxiv.org/abs/2406.12005
On astro-ph today: Cosmological simulations of the generation of cluster-scale radio emission from turbulent re-acceleration led by L. Beduzzi. Shows that radio megahalos can be powered by turbulence. arxiv.org/abs/2406.09859

Published in #MNRAS: "MeerKAT discovery of a double radio relic and odd radio circle: connecting cluster and galaxy merger shocks", Koribalski et al. This is Fig. 3: for the caption & to read the paper please visit academic.oup.com/mnras/artic…
ALT RGB colour image of the double relic cluster PSZ2 G277.93 + 12.34. The MeerKAT 1.3 GHz radio continuum emission is shown in red plus yellow contours (0.01, 0.1, and 1 mJy beam^(−1)), the eRASS:3 X-ray emission in blue plus white contours (same levels are as in Fig. 2), and the DSS2 optical R-band image in green. For display purposes, we show the radio emission without primary beam correction.
And another paper of ours came out today: @LOFAR Deep Fields: Probing the sub-mJy regime of polarized extragalactic sources in ELAIS-N1. led by S. Piras with @aghatubrid and others. Deepest and highest-resolution polarization study at 150 MHz to date. arxiv.org/abs/2406.08346

The ultimate faculty recruitment list: Hermann Weyl recommending physicists and mathematicians as directors for the IAS in 1945. The competition is so stiff that Wigner and Bethe are considered second-tier. Oppenheimer is the "most inspiring for younger physicists."

Great paper and some amazing visualisations! @PlotAstro

Nice paper led by our student L. Gajovic on what happens if you observe galaxies at frequencies of 50 MHz @LOFAR . arxiv.org/abs/2406.06689 with @VolkerHeesen @fradega @hen_edler et al.
