Simulations for a next-generation UHECR observatory
Foteini Oikonomou, Kumiko Kotera, Filipe B. Abdalla
We explore the potential of a future, ultra-high energy cosmic ray (UHECR) experiment, that is able to overcome the limitation of low statistics, to detect anisotropy in the arriva…
On ultra-high energy cosmic ray acceleration at the termination shock of young pulsar winds
Martin Lemoine, Kumiko Kotera, Jérôme Pétri
Pulsar wind nebulae (PWNe) are outstanding accelerators in Nature, in the sense that they accelerate electrons up to the radiation reaction limit. Motivated by this observation, th…
Synchrotron pair halo and echo emission from blazars in the cosmic web: application to extreme TeV blazars
Foteini Oikonomou, Kohta Murase, Kumiko Kotera
High frequency peaked high redshift blazars, are extreme in the sense that their spectrum is particularly hard and peaks at TeV energies. Standard leptonic scenarios require peculi…
What could we learn from a sharply falling positron fraction?
Timur Delahaye, Kumiko Kotera, Joseph Silk
Recent results from the AMS-02 data have confirmed that the cosmic ray positron fraction increases with energy between 10 and 200GeV. This quantity should not exceed 50%, and it is…
