    Axion-like particle imprint in cosmological very-high-energy sources
    Discoveries of very high energy (VHE) photons from distant blazars suggest that, after correction by extragalactic background light (EBL) absorption, there is a...

    Axion-pion thermalization rate in unitarized NLO chiral perturbation theory
    We compute the axion-pion scattering a π →π π , relevant for the axion thermalization rate in the early Universe, within unitarized next-to-leading-order chiral...

    Axisymmetrical gas inflow in the central region of NGC 7331
    New Integral Field Spectroscopy of the central region of NGC 7331 reveals strong Hα emission in the well-known CO and HI ring of NGC 7331. The [NII]/Hα ratio...

    Azimuthal anisotropy of charged particles with transverse momentum up to 100 GeV/c in PbPb collisions at √{sNN } = 5.02 TeV
    The Fourier coefficients v2 and v3 characterizing the anisotropy of the azimuthal distribution of charged particles produced in PbPb collisions at √{sNN } = 5...
  • Publication
    Azimuthal correlations for inclusive 2-jet, 3-jet, and 4-jet events in pp collisions at √{s}= 13 TeV
    Azimuthal correlations between the two jets with the largest transverse momenta pT in inclusive 2-, 3-, and 4-jet events are presented for several regions of...
  • Publication
    Azimuthal decorrelation of jets widely separated in rapidity in pp collisions at √{s}=7 TeV
    The decorrelation in the azimuthal angle between the most forward and the most backward jets (Mueller-Navelet jets) is measured in data collected in pp...
  • Publication
    Azimuthal dependence of the density distribution in outer galactic discs accreting intergalactic flows
    Aims: The amplitude and scaleheight of the Galactic gas disc density are not axisymmetric against expectations in a self-gravity axisymmetric disc. However...

    B field in OB stars (BOB): The outstandingly strong magnetic field in the evolved He-strong star CPD -62° 2124
    The origin and evolution of magnetism in OB stars is far from being well understood. With approximately 70 magnetic OB stars known, any new object with unusual...
  • Publication
    B fields in OB stars (BOB). Detection of a strong magnetic field in the O9.7 V star HD 54879
    The number of magnetic stars detected among massive stars is small; nevertheless, the role played by the magnetic field in stellar evolution cannot be...
