O.; Arakawa, M.; Arrieta, M.; Aubert, P.; Backes, M.; Balzer, A.; Barnard, M.; Chen, A.; Jingo, M.; Komin, N.; Shafi, N. (EDP Sciences, 2017-01-01)
    Aims. Following the detection of the fast radio burst FRB150418 by the SUPERB project at the Parkes radio telescope, we aim to search for very-high energy gamma-ray afterglow emission. Methods. Follow-up observations in ...

(EDP Sciences, 2017-02)
    Studying the temporal variability of BL Lac objects at the highest energies provides unique insights into the extreme physical processes occurring in relativistic jets and in the vicinity of super-massive black holes. To ...

    Context. The addition of a 28 m Cherenkov telescope (CT5) to the H.E.S.S. array extended the experiment's sensitivity to lower energies. The lowest energy threshold is obtained using monoscopic analysis of data taken with ...
  • De Mello Koch, R.; Van Zyl, H.J.R. (Elsevier, 2017-05)
    We study the worldsheet S-matrix of a string attached to a D-brane in AdS5×S5. The D-brane is either a giant graviton or a dual giant graviton. In the gauge theory, the operators we consider belong to the su(2|3)sector of ...
  • Kudoda, A.M.; Faltenbacher, A. (Oxford University Press (OUP), 2017-06)
    This study investigates the impact of the fluctuations in the extragalactic background light (EBL) on the attenuation of the hard gamma-ray spectra of distant blazars. EBL fluctuations occur on the scales up to 100 Mpc and ...
  • Gras, P.; Höche, S.; Kar, D.; Larkoski, A.; Lönnblad, L.; Plätzer, S.; Siódmok, A.; Skands, P.; Soyez, G.; Thaler, J. (Springer Verlag, 2017-07)
    By measuring the substructure of a jet, one can assign it a “quark” or “gluon” tag. In the eikonal (double-logarithmic) limit, quark/gluon discrimination is determined solely by the color factor of the initiating parton ...
  • Coleppa, B.; Kumar, M.; Kumar, S.; Mellado, B. (Elsevier, 2017-07)
    We investigate the sensitivity of top-Higgs coupling by considering the associated vertex as CP phase (ζt) dependent through the process pe−→t¯hνe in the future Large Hadron electron Collider. In particular the decay modes ...
  • Marchegiani, P.; Colafrancesco, S. (Oxford University Press (OUP), 2017-08)
    A recent stacking analysis of Planck HFI data of galaxy clusters led to the derivation of the cluster temperatures using the relativistic corrections to the Sunyaev-Zel'dovich effect (SZE). However, the temperatures of ...
  • Akbal, O.; Buchner, S.; Pines, D.; Alpar, M.A. (Oxford University Press (OUP), 2017-08)
    The interglitch timing of the Vela pulsar is characterized by a constant second derivative of the rotation rate. This takes over after the post-glitch exponential relaxation and is completed at about the time of the next ...
  • Prokhorov, D.A.; Churazov, E.M. (Oxford University Press (OUP), 2017-09)
    While rich clusters are powerful sources of X-rays, γ -ray emission from these large cosmic structures has not been detected yet. X-ray radiative energy losses in the central regions of relaxed galaxy clusters are so strong ...
