On the Riemann problem for the Adlam-Allen model
Su Yang, Marco Calabrese, Vassilis Koukouloyannis +1
In the present work, we revisit the Adlam-Allen (AA) model in order to investigate its numerically observed rarefaction and dispersive shock waves that arise in numerical simulatio…

Euclid preparation: Testing multi-field inflation with galaxy power spectrum and bispectrum
Euclid Collaboration, D. Linde, A. Moradinezhad Dizgah +281
Primordial non-Gaussianity (PNG) is a powerful probe of the origin of cosmic structure. Stage-IV surveys like \Euclid will measure galaxy - and -point clustering at high sign…

Hydromagnetic shock waves in a cold weakly collisional plasma
Marco Calabrese, Vassilis Koukouloyannis, Sibtain Abbas +2
In this work we revisit the topic of existence of hydrodynamic shock waves in a cold weakly collisional plasma. For this purpose we consider the well established Adlam-Allen model…
