An analysis of the energy spectra of cosmic rays and particularly the precise data from the AMS-02 experiment support the view about the important role of the Local Bubble in the nearby interstellar medium. It is suggested that the bulk of CR below about 200 GV of rigidity (momentum/charge ratio) comes from the modest number of supernova remnants in the Local Bubble which appear to have occurred some 10years ago and contributed to its formation. At higher rigidities the contribution from a… Expand
From Cosmic Explosions to Terrestrial Fires?
TLDR
This work argues for the likelihood of cosmic ray ionization of the atmosphere and electron cascades leading to more frequent lightning and therefore an increase in nitrate deposition and wildfires, and the potential exists for a large increase in the prehuman nitrate flux onto the surface. Expand
Probing new physics underground
Throughout the Universe we measure the gravitational effect of dark matter (DM). This DM makes up around 63% of the total matter in the Universe today and cannot be explained by the normalExpand

Properties of the Interstellar Medium and the Propagation of Cosmic Rays in the Galaxy
Abstract The problem of the origin of cosmic rays in the shocks produced by supernova explosions at energies below the so-called ‘knee’ (at ∼3×106 GeV) in the energy spectrum is addressed, withExpand
Secondary cosmic ray nuclei in the light of the Single Source Model
Evidence for a local 'Single Source' of cosmic rays is amassing by way of the recent precise measurements of various cosmic ray energy spectra from the AMS-02 instrument. To observations ofExpand

An analysis is made of the cosmic ray energy spectrum expected from supernova remnant acceleration of cosmic rays for energies below the well known knee at 3×106 GeV. Two models are considered; thatExpand
The local bubble, local fluff, and heliosphere
The properties of the Local Bubble, Local Fluff complex of nearby interstellar clouds, and the heliosphere are mutually constrained by data and theory. Observations and models of the diffuseExpand
Signatures of a Two Million Year Old Supernova in the Spectra of Cosmic Ray Protons, Antiprotons, and Positrons.
TLDR
The age of the supernova suggests that the local cosmic ray injection was produced by the same supernova that has deposited ^{60}Fe isotopes in the deep ocean crust. Expand
Cosmic ray positrons from a local, middle-aged supernova remnant
Abstract We argue that the cosmic ray positron excess observed in ATIC-2, Fermi LAT, PAMELA, HESS and recently in the precision AMS-02 experiment can be attributed to production in a local,Expand
Decaying cosmic ray nuclei in the local interstellar medium
Secondary radioactive isotopes that are used for the determination of cosmic ray age, have relatively short decay lifetimes. The measured abundance of these isotopes at low energies is representativeExpand

In view of the fact that the AMS-02 instrument has recently been used to make preliminary observations of the ratio of the antiprotons (\-{P}) to protons (P) in the primary cosmic radiation we haveExpand
The radial gradient of cosmic ray intensity in the Galaxy
Abstract The dependence of the cosmic ray intensity on Galactocentric distance is known to be much less rapid than that of the thought-to-be sources: supernova remnants. This is an old problem (‘theExpand
A new component of cosmic rays
Recent direct measurements of the energy spectra of the major mass components of cosmic rays have indicated the presence of an 'ankle' in the region of 200 GeV per nucleon . The ankle, which variesExpand
