  • Properties of Daily Helium Fluxes
    We present the precision measurement of 2824 daily helium fluxes in cosmic rays from May 20, 2011 to October 29, 2019 in the rigidity interval from 1.71 to 100 GV based on 7.6 ×10 8 helium nuclei collected with the Alpha Magnetic Spectrometer (AMS) aboard the International Space Station. The helium flux and the helium to proton flux ratio exhibit

  • Searching for dark-matter waves with PPTA and QUIJOTE pulsar polarimetry
    The polarization of photons emitted by astrophysical sources might be altered as they travel through a dark matter medium composed of ultra light axion-like particles (ALPs). In particular, the coherent oscillations of the ALP background in the galactic halo induce a periodic change on the polarization of the electromagnetic radiation emitted by

  • The 700 ks Chandra Spiderweb Field. I. Evidence for widespread nuclear activity in the protocluster
    Aims: We present an analysis of the 700 ks Chandra ACIS-S observation of the field around the radio galaxy J1140-2629 (the Spiderweb Galaxy) at z = 2.156, focusing on the nuclear activity in the associated large-scale environment. Methods: We identified unresolved X-ray sources in the field down to flux limits of 1.3 × 10 −16 and 3.9 × 10 −16 erg s
