#GW230814 is such a beautifully loud signal. An signal-to-noise ration of 42 using just one detector! That is louder than GW170817 observed with three. It is amazing the progress the detectors are making, and the science that these measurements can bring

The loudest #GravitationalWave in #GWTC4 is #GW230814
Detected with only Livingston, it was still about twice as loud as GW150914!
Being loud should enable precision tests of general relativity, but with only one detector, you need to be careful with the analysis

💥💥 Double detonation!
For the first time, astronomers have obtained visual evidence that a star met its end by detonating twice.
The fingerprint that points to this mechanism is represented by two separate shells of calcium.

Jets, particle sprays coming from quarks and gluons, can't easily pass through the blob that is the quark-gluon plasma, a phenomenon called "jet quenching". This #CMSPaper investigates if that also happens with an alternative method where the angles between two jets are used arxiv.org/abs/2504.08507

One of the problems with the standard model is that we use different mathematics for low-energy than for high-energy strong force calculations. The transition region is not so easy. #CMSPaper 1392 measures the transition region for the first time in LHC heavy ion collisions arxiv.org/abs/2503.19993
