Article Synopsis
- Scientists studied the kinematic Sunyaev-Zel'dovich (kSZ) effect using data from two telescopes, the South Pole Telescope and Herschel-SPIRE, covering a large area in the sky.
- They found a strong signal indicating that there is a trispectrum, which is a kind of pattern in the data, but it had contributions from other sources too, like cosmic microwave background lensing and foregrounds.
- By analyzing the data, they couldn't find just the kSZ signal alone, but they set limits on how long the reionization period lasted in the early universe, which helps us understand its history better.
Article Synopsis
- This study introduces a method for effectively removing template molecules from molecularly imprinted polymers using heat-activated persulfate, addressing issues with incomplete template removal seen in current techniques.
- The research utilized a polymer designed for Coenzyme Q extraction to test this new approach, ensuring that the heat treatment accurately eliminated the template without compromising the polymer's performance.
- Results showed that this method is efficient and eco-friendly, providing comparable selectivity for target analytes to traditional methods, marking a significant improvement in trace analysis applications.
This Letter reports the observation of single top quarks produced together with a photon, which directly probes the electroweak coupling of the top quark. The analysis uses 139 fb^{-1} of 13 TeV proton-proton collision data collected with the ATLAS detector at the Large Hadron Collider. Requiring a photon with transverse momentum larger than 20 GeV and within the detector acceptance, the fiducial cross section is measured to be 688±23(stat) _{-71}^{+75}(syst) fb, to be compared with the standard model prediction of 515_{-42}^{+36} fb at next-to-leading order in QCD.

The dataset corresponds to an integrated luminosity of 1.44 nb^{-1} of LHC Pb+Pb collisions at sqrt[s_{NN}]=5.

The collective expansion of such droplets is well described by viscous hydrodynamics. Similar evidence of collectivity is consistently observed in smaller collision systems, including pp and p+Pb collisions.
