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.

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.

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."

My second paper is on ArXiv today!
We performed MHD simulations of NGC1275, the brightest central galaxy of the Perseus cluster to study the formation and evolution of cold gas filaments.
