Now we are ready to move on to the next big scientific enterprise, with the Electron Ion Collider and its promise of new exciting physics. But RHIC data will continue to keep us busy for years to come, and will stand as a crucial milestone for physics.

I still remember the announcement of the Quark-Gluon Plasma discovery, how excited we were at the conferences looking at the first data and trying to interpret them. For the last 25 years RHIC continued to deliver incredibly compelling discoveries.

Yesterday we watched the closing ceremony for the Relativistic Heavy Ion Collider (RHIC) @brookhavenlab. For somebody like me, who started my Ph.D. in heavy ion physics in 2000, the year when RHIC started its operations, it was an emotional moment.

What a day! I started with an online talk at my former Ph.D. advisor's retirement workshop, and a few hours later I celebrated the successful Ph.D. defense of my student 🀩 I am reflecting on the impact that my advisor had on my life, and trying to propagate it forward to my own students.

Very grateful to the organizers of our biggest conference, Quark Matter 2025, for streaming all the talks! We all cheered remotely for our undergrad @jappus.bsky.social today, who gave his talk at the conference in Frankfurt. He did so well! 🀩

Evidence for freeze-out of charge fluctuations in the quark-gluon plasma at the LHC The D-measure of event-by-event net-charge fluctuations was introduced over 20 years ago as a potential signal of quark-gluon plasma (QGP) in heavy-ion collisions, where it is expected to be suppresse...

New paper day! We calculate the D-measure in a hadronic vs quark-gluon plasma scenarios and compare to LHC data, finding moderate evidence for fluctuations freezing out in the quark phase. arxiv.org/abs/2504.02085

A new 4D lattice QCD equation of state: extended density coverage from a generalized $T^\prime$-expansion We present a new equation of state for QCD in which the temperature $T$ and the three chemical potentials for baryon number $ΞΌ_B$, electric charge $ΞΌ_Q$ and strangeness $ΞΌ_S$ can be varied independent...

New paper day! 4D equation of state for strongly interacting matter with extended coverage from first principles! www.arxiv.org/abs/2504.01881
