Hunting for quark matter in neutron star cores
Neutron stars are the densest objects in the present-day universe. In the extreme conditions of their cores, even the particles found in atomic nuclei, protons and neutrons, are believed to dissolve into quarks. As far as is known, such quark matter is not found anywhere else.
Professor Aleksi Vuorinen’s (Faculty of Science) project combines complex quantum-field-theoretical calculations with neutron star observations to either confirm or disprove the occurrence of this new state of matter in neutron star cores.
The project aims to advance understanding of the fundamental structure of matter and the laws of nature under extreme conditions.

Improved technique could reveal beyond standard model particles in CERN detector
HIP researchers have developed a new method to improve the identification of latent tracks in nuclear track detectors:
“The MoEDAL experiment employs solid-state nuclear track detector foils around Interaction Point 8 to search for traces of highly ionizing particles. The selected material, CR-39, has been used in several experiments and is capable of detecting ionization tracks down to the level of oxygen ions. However, due to the high-radiation environment of the Large Hadron Collider, the material becomes opaque after chemical etching and exhibits strong scattering properties. This complicates the identification of low-ionization tracks. By deploying liquid thin films on both sides of the irradiated foils and using machine-vision techniques, etch pits in the foils can be detected and classified.”

Breakthrough in Nuclear Magnetism at CERN’s ISOLDE

Scientists at CERN’s ISOLDE facility have, for the first time, observed how magnetism is distributed within an atomic nucleus using high-resolution molecular measurements — a result that opens new avenues in nuclear and molecular physics. Our member university, the University of Jyväskylä, participated in this international research team, reflecting the impact of our ISOLDE project collaboration in advancing fundamental physics. The original post includes images and details of the technique and findings.
