An Efficient Method for Simulating Light Curves of Cosmological Microlensing and Caustic Crossing Events
Ashish Kumar Meena, Ofir Arad, Adi Zitrin
A new window to observing individual stars and other small sources at cosmological distances was opened recently, with the detection of several caustic-crossing events in galaxy cl…
Maximally-hard spectra from diffusive shock-acceleration in pulsar-wind nebulae
Ofir Arad, Assaf Lavi, Uri Keshet
The processes leading to the exceptionally hard radio spectra of pulsar-wind nebulae (PWNe) are not yet understood. Radio photon spectral indices among PWNe from the literatur…
Diffusive shock acceleration in dimensions
Assaf Lavi, Ofir Arad, Yotam Nagar +1
Collisionless shocks are often studied in two spatial dimensions (2D), to gain insights into the 3D case. We analyze diffusive shock acceleration for an arbitrary number $N\in\math…
Diffusive shock-acceleration: breakdown of spatial diffusion and isotropy
Uri Keshet, Ofir Arad, Yuri Lyubarski
We point out that particles accelerated in a non-relativistic shock of compression ratio attain the standard, spectral index only under certain conditions. Prev…
