“…The idea that pulsars might be associated with the production of cosmic ray electrons/positrons is quite old, see [64,65,66], and has been periodically reconsidered in the past decade, see e.g. [67,68].…”

Over the last three years, several satellite and balloon observatories have suggested intriguing features in the cosmic ray lepton spectra. Most notably, the PAMELA satellite has suggested an "anomalous" rise with energy of the cosmic ray positron fraction. In this article, we summarize the global picture emerging from the data and recapitulate the main features of different types of explanations proposed. The perspectives in testing different scenarios as well as inferring some astrophysical diagnostics from current/near future experiments are also discussed.

“…Pulsars are the primary charge-symmetric suspects as they disconnect positrons from nuclear species and therefore remove the constraints associated with production of other secondaries. Probably, the first mention of pulsars as sources of CR positrons can be found in [148], and the first calculation of secondary production and pulsar contribution to CR positrons -in [149]. A calculation of the positron fraction using the data available at that time (contaminated by protons above ≈5 GeV) was performed in [150].…”

The last two decades have brought spectacular advances in astrophysics of cosmic rays (CRs) and space-and ground-based astronomy. Launches of missions that employ forefront detector technologies enabled measurements with large effective areas, wide fields of view, and precision that we recently could not even dream of. Meanwhile, interpretation of the individual slices of information about the internal working of the Milky Way provided by such experiments poses challenges to the traditional astrophysical models. New mysteries arise in the composition and spectra of CR species at low and high energies, in the energy range where we thought the main features were already understood fairly well. This accumulation of unsolved puzzles highlights the peculiarity of the current epoch and means that major breakthroughs are still ahead. In my talk, I review the current state of direct measurements of CRs and discuss their possible interpretations. Unfortunately, many important ideas and publications are not discussed here due to the space limitations.

“…Анализу влияния ускоренных частиц на фронты ударных волн посвящено много работ, см. в частности работы [66,81,[88][89][90][91][92]. Последователь ная и строгая теория этого явления сводится, по существу, к проблеме структуры фронта бесстол кновительной ударной волны, которая несмотря на значительный прогресс в понимании основных процессов, пока далека от решения.…”
