The impact of nonlinear Landau damping on cosmic ray streaming and the role of external turbulence
Rouven Lemmerz, Mohamad Shalaby, Ellen Zweibel +2
Cosmic rays (CRs) streaming faster than the Alfvén speed generate Alfvén waves that scatter them. The saturated wave amplitude is regulated by a damping mechanism. This damping con…
Saturation Mechanism of Cosmic Ray Streaming Instabilities with a Shell Distribution
Mohamad Shalaby, Rouven Lemmerz, Christoph Pfrommer
Cosmic rays (CRs) drive galactic winds and regulate galaxy growth while contributing to heating the central cooling plasma in dense galaxy clusters, making the nonlinear saturation…
The Sound of the Universe: A Resonant Gravitational Instability Driven by Baryon-Dark Matter Relative Drift
Mohamad Shalaby, Avery Broderick
Dark matter and baryons acquire a relative velocity after decoupling in the early Universe. Baryons are gravitationally unstable only above their Jeans scale, while cold dark matte…
