Out today: The Coma cluster at @LOFAR frequencies II: the halo, relic, and a new accretion relic led by @AnnalisBonafede with @fradega @roxycas @and_botteon @CStuardi @fabiogasta @cjriseley @marisa_brienza @mcrossetti_twit et al. arxiv.org/abs/2203.01958

‼️The @Planck clusters in the @LOFAR sky‼️
This is a huge project where we used 309 (!!) PSZ2 clusters to study diffuse radio sources in the ICM (halos and relics).
Paper I (accepted in @AandA_journal) -> arxiv.org/abs/2202.11720

Il telescopio spaziale tedesco @eROSITA_SRG a bordo della missione russo-tedesca #Spektr-RG è stato messo in 'safe mode' in attesa di sviluppi. #UkraineRussiaWar lascerà un segno indelebile anche nella mappa del cielo nei raggi X.

📡 Pubblicata la più grande e nitida mappa del cielo a frequenze #radio ultra-basse grazie a @LOFAR
Copre il 2% del cielo e include:
🔸buchi neri supermassicci
🔸materia diffusa nell’universo
🔸esopianeti

The MeerKAT radio telescope has discovered two giant gas bubbles above and below the centre of the Milky Way. The bubbles could have been formed by the near-simultaneous formation and fiery death of roughly 100 large stars. go.nature.com/2ZYoRv0
