Reacceleration of Galactic Cosmic Rays Beyond the Knee at the Termination Shock of a Cosmic-Ray-Driven Galactic Wind

Kavli Affiliate: Roger Blandford | First 5 Authors: Payel Mukhopadhyay, Enrico Peretti, Noemie Globus, Paul Simeon, Roger Blandford | Summary: The origin of cosmic rays above the knee in the spectrum is an unsolved problem. We present a wind model in which interstellar gas flows along a non-rotating, expanding flux tube with a changing speed […]

Dynamically Stable Radiation Pressure Propulsion of Flexible Lightsails for Interstellar Exploration

Kavli Affiliate: Harry A. Atwater | First 5 Authors: Ramon Gao, Michael D. Kelzenberg, Harry A. Atwater, , | Summary: Lightsail spacecraft, propelled to relativistic velocities via photon pressure using high power density laser radiation, offer a potentially new route to space exploration within and beyond the solar system, extending to interstellar distances. Such missions […]
