    Listen to heavy ions collide in the #LHC! 🎶🎇 Data from the ATLAS detector has been transformed into a symphony of sounds via Quantizer, a @medialab sonification platform. Listen to even more ATLAS collisions LIVE at quantizer.media.mit.edu.

    Eight years on and we've learnt a lot about the #Higgsboson since announcing its discovery at @CERN. The ATLAS Experiment has been putting this unique particle through its paces – here’s what we’ve uncovered so far. THREAD ⤵️
    How time flies: it has been eight years since @ATLASexperiment and @CMSExperiment announced the discovery of the #HiggsBoson! Happy Higgs discovery day!

    Today marks the last day of proton-proton collisions for Run 2 of the LHC! In total, ATLAS has recorded 149 fb-1 of data at 13 TeV – a huge dataset for physicists to study the Standard Model and probe for hidden signatures.

    New milestone! The first module of the New Small Wheel detectors was installed today at @CERN. These new wheels will replace of the innermost sections of the muon-detection system in the end-caps of ATLAS.
