We present a comprehensive discussion about the origin of the features in the leptonic component of the cosmic-ray spectrum. Working in the framework of a up-to-date CR transport scenario tuned on the most recent AMS-02 and Voyager data, we show that the prominent features recently found in the positron and in the all-electron spectra by several experiments are explained in a scenario in which pulsar wind nebulae (PWNe) are the dominant sources of the positron flux, and nearby supernova remnants shape the highenergy peak of the electron spectrum. In particular we argue that the drop-off in positron spectrum found by AMS-02 at ∼ 300 GeV can be explained -under different assumptionsin terms of a prominent PWN that provides the bulk of the observed positrons in the ∼ 100 GeV domain, on top of the contribution from a large number of older objects. Finally, we turn our attention to the spectral softening at ∼ 1 TeV in the all-lepton spectrum, recently reported by several experiments, showing that it requires the presence of a nearby supernova remnant at its final stage.

“…Not all experiments are able to measure the electrons and positrons separately. Here measurements by Aguilar et al (2019a), Adriani et al (2009) and Beatty et al (2004) are reported, together with a number of model predictions: the black curve is for pure secondary production in the standard scenario (Moskalenko & Strong 1998); the blue curve includes a more sophisticated propagation model (Gaggero et al 2013); the green curve invokes dark matter decay (Ibarra, Tran & Weniger 2013); the red curve includes a contribution from pulsars (Yin et al 2013). 100 : 1 (https://lpsc.in2p3.fr/crdb/).…”

Accelerated particles are ubiquitous in the Cosmos and play a fundamental role in many processes governing the evolution of the Universe at all scales, from the sub-AU scale relevant for the formation and evolution of stars and planets to the Mpc scale involved in Galaxy assembly. We reveal the presence of energetic particles in many classes of astrophysical sources thanks to their production of non-thermal radiation, and we detect them directly at the Earth as cosmic rays. In the last two decades both direct and indirect observations have provided us a wealth of new, high-quality data about cosmic rays and their interactions both in sources and during propagation, in the Galaxy and in the Solar System. Some of the new data have confirmed existing theories about particle acceleration and propagation and their interplay with the environment in which they occur. Some others have brought about interesting surprises, whose interpretation is not straightforward within the standard framework and may require a change of paradigm in terms of our ideas about the origin of cosmic rays of different species or in different energy ranges. In this article, we focus on cosmic rays of galactic origin, namely with energies below a few petaelectronvolts, where a steepening is observed in the spectrum of energetic particles detected at the Earth. We review the recent observational findings and the current status of the theory about the origin and propagation of galactic cosmic rays.

“…No significant deviation from isotropy can be observed. The limit obtained for the energy range from 16 to 350 GeV is δ < 0.019 for positrons and δ < 0.005 for electrons as reported in [8,9]. To check for possible unknown systematics in the creation of the IsoSky maps a similar analysis was performed using protons and electrons as a reference for positrons and protons as a refer-…”
