‼️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 Project website -> lofar-surveys.org/planck_dr2… 1/13

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.

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

A new, distant, radio halo discovered with @LOFAR, by Cassano+ (@roxycas, @fabiogasta, @HambObs, @IRA_INAF) #irapapers Being at z=0.616, PSZ2G099 is one of the most distant halos known so far and its emission is barely detected at 1.4 GHz with the JVLA 1/2 arxiv.org/abs/1907.10304

Scientists have obtained the first image of a black hole, using Event Horizon Telescope observations of the center of the galaxy M87. The image shows a bright ring formed as light bends in the intense gravity around a black hole that is 6.5 billion times more massive than the Sun

This is M87* and this the first image of a black hole! Mass is 6.5 Billion suns within size of a solar system. Precious because real. Waited 25 years for this. Dark shadow is where light disappears in #eventhorizon. We see something never seen before. #blackhole #JustWow #EHT

Tim Shimwell of @ASTRON_NL blows #SKASciCon19 away with the amazing @LOFAR Two-Metre Sky Survey (LoTSS). LoTSS has detected more radio galaxies than all other surveys combined (with only ~20% finished). This is allowing @SKA_telescope science now!

Big sky survey by @LOFAR has detected hundreds of thousands of previously undetected galaxies, shedding new light on black holes & how clusters of galaxies evolve. The first 26 articles have just been published in @AandA_journal astron.nl/new-sky-map-detect…
