Inferences on Mass Composition and Tests of Hadronic Interactions from 0.3 to 100 EeV using the water-Cherenkov Detectors of the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Aab, P. Abreu +403
We present a new method for probing the hadronic interaction models at ultra-high energy and extracting details about mass composition. This is done using the time profiles of the…
H and H emission in a C3.3 solar flare: comparison between observations and simulations
Vincenzo Capparelli, Francesca Zuccarello, Paolo Romano +7
The Hydrogen Balmer series is a basic radiative loss channel from the flaring solar chromosphere. We report here on the analysis of an extremely rare set of simultaneous observatio…
Spectral Calibration of the Fluorescence Telescopes of the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Aab, P. Abreu +403
We present a novel method to measure precisely the relative spectral response of the fluorescence telescopes of the Pierre Auger Observatory. We used a portable light source based…
Observation of a Large-scale Anisotropy in the Arrival Directions of Cosmic Rays above eV
The Pierre Auger Collaboration, A. Aab, P. Abreu +404
Cosmic rays are atomic nuclei arriving from outer space that reach the highest energies observed in nature. Clues to their origin come from studying the distribution of their arriv…
Observational Evidence of a Flux Rope within a Sunspot Umbra
Salvo L. Guglielmino, Paolo Romano, Francesca Zuccarello
We observed an elongated filamentary bright structure inside the umbra of the big sunspot in active region NOAA 12529, which differs from the light bridges usually observed in suns…
Polarised kink waves in magnetic elements: evidence for chromospheric helical waves
Marco Stangalini, Fabio Giannattasio, Robertus Erdélyi +6
In recent years, new high spatial resolution observations of the Sun's atmosphere have revealed the presence of a plethora of small-scale magnetic elements down to the resolution l…
