• DISCREPANT HARDENING OBSERVED IN COSMIC-RAY ELEMENTAL SPECTRA (2010, background): “Alternatively, the source spectra could be harder than previously thought based on the low energy data, or the hardening could reflect the predicted concavity in the spectra before the ―knee‖ (Hillas 2005).”
• Teraelectronvolt Astronomy (2010, background): “…remnants at high energy by Reynolds (2008), the discussion of whether acceleration in supernova remnants can account for galactic cosmic rays by Hillas (2005), the review of cosmic-ray propagation and interactions by Strong, Moskalenko & Ptuskin (2007) and the review of pulsar wind nebulae by…”
• Dark Matter Searches with Astroparticle Data (2011, background): “…because there are a variety of production mechanisms for high-energy electrons and positrons: acceleration at shocks (e.g., Lagage & Cesarsky, 1983; Hillas, 2005) (electrons only), production of secondary electrons/positrons in situ by shock accelerated hadrons (e.g., Blasi, 2009), pair production…”
• Cosmic-ray energy spectrum and composition up to the ankle - the case for a second Galactic component (2016, methodology): “Between ⇠108 and 109 GeV, the predicted all-particle spectrum in Hillas (2005) consists of a significant iron fraction which may be in agreement with the hln Ai data when mixed with a strong extra-galactic proton component, but is in tension with the small A33, page 17 of 24 iron fraction (⇠2 10”
• Non-linear particle acceleration at non-relativistic shock waves in the presence of self-generated turbulence (2006, background): “…predictions. c© 0000 RAS, MNRAS 000, 000–000 From the phenomenological point of view, the best evidences for both magnetic field amplification and efficient particle acceleration come from observations of supernova remnants (see the reviews of Hillas (2005) and Blasi (2005) and references therein).”
• Theoretical Challenges in Galaxy Formation (2016, background): “…the ’knee’ in the CR spectrum is considered to be diffusive shock acceleration (DSA, see e.g. Bell 1978, Blandford & Ostriker 1978) and non-linear DSA (Malkov & O’C Drury 2001) in shocks of supernova remnants (SNR) (see Hillas 2005, for a review, and recent observations by Ackermann et al. 2013).”
• Cosmic ray acceleration and escape from supernova remnants (2013, background): “A slightly less rapid decrease in shock velocity, us ∝ t−0.57 (q = 4/3), would reproduce the CR spectral index (α ≈ 2.2) inferred for CR at their source at energies less than 1PeV (Gaisser et al 1998, Hillas 2005).”
• Strong evidence for hadron acceleration in Tycho’s supernova remnant (2011, methodology): “As estimated for instance in§3 of the review by Hillas (2005), such a value is consistent with the hypothesis that SNRs are the sources of Galactic CRs, provided that the residencetime in the Milky Way scales with∼ E−1/3.”
• Broad-band non-thermal emission from molecular clouds illuminated by cosmic rays from nearby supernova remnants (2009, background): “…CR flux at the observed level, provided that a fraction of about 10% of their explosion energy is somehow converted into CRs (Baade and Zwicky 1934; Hillas 2005), and ii) the fact that some shell-type SNRs have been detected at TeV energies (see Aharonian et al. 2008, for a review), as expected if…”
