Erratum: “Self-consistent 3D Radiative Transfer for Kilonovae: Directional Spectra from Merger Simulations” (2023, ApJL, 954, L41)
No full textFRS-R3B Software
No full textThe FRS-R3B directory within R3BRoot contains the software for the FRS (Fragment Separator) detectors that are utilized in the FRS-R3B experiments. The FRS is a pivotal instrument for investigating nuclear reactions with relativistic radioactive beams, enabling high-precision studies of exotic nuclei and nuclear structure at the limits of stability. This software is built upon the FairRoot framework, which provides the tools necessary for both Monte Carlo simulations and data analysis of experimental results. The R3B experimental program is part of the broader nuclear physics research efforts at the FAIR (Facility for Antiproton and Ion Research), a cutting-edge international research facility that utilizes heavy-ion and antiproton beams to explore fundamental questions in nuclear physics, with a particular focus on the production and behavior of rare isotopes under extreme conditions. The FRS-R3B software package is a source distribution with recurring releases for macOS and Linux
AsyEOS Software
No full textThe AsyEOS (Asymmetric-matter Equation-Of-State) directory within the R3BRoot framework provides the full detector definitions, Monte Carlo simulation tools, and digitization algorithms for the detectors used in the AsyEOS/R3B (Reactions with Relativistic Radioactive Beams) experimental campaign at the GSI/FAIR (Facility for Antiproton and Ion Research) facility. AsyEOS-R3BRoot, developed on top of the FairRoot framework, is a versatile toolkit for performing Monte Carlo simulations and processing experimental data to measure the flows of neutrons and light charged particles produced in Nucleus-Nucleus collisions in order to investigate symmetry energy of the nuclear equation of state at densities above the saturation one. The AsyEOS software package is a source distribution with recurring releases for macOS and Linux

No full textMeasurement of the inclusive isolated-photon production cross section in pp collisions at TeV
No full textThe production cross section of inclusive isolated photons has been measured by the ALICE experiment at the CERN LHC in pp collisions at centre-of-momentum energy of TeV collected during the LHC Run 2 data-taking period. The measurement is performed by combining the measurements of the electromagnetic calorimeter EMCal and the central tracking detectors ITS and TPC, covering a pseudorapidity range of and a transverse momentum range of GeV/. The result extends to lower and ranges, the lowest of any isolated photon measurements to date, extending significantly those measured by the ATLAS and CMS experiments towards lower at the same collision energy with a small overlap between the measurements. The measurement is compared with next-to-leading order perturbative QCD calculations and the results from the ATLAS and CMS experiments as well as with measurements at other collision energies. The measurement and theory prediction are in agreement with each other within the experimental and theoretical uncertainties

No full textThe Astrophysical Thoughts of Carl Friedrich von Weizsäcker
No full textCarl Friedrich von Weizsäcker published two important papers on topics of nuclear astrophysics in 1937 and 1938 before he turned his attention elsewhere motivated by the discovery of fission and the outbreak of war in 1939. It seems, however, that he continued to actively think about issues related to astrophysics, namely the discussion and role of neutron stars and cosmology. Both are contemporary topics today. This paper presents the development of Weizsäcker’s thoughts in the years between 1935 and 1945, making use of his personal notes and letters
