We briefly review helicity dynamics, inverse and bidirectional cascades in fluid and
magnetohydrodynamic (MHD) turbulence, with an emphasis on the latter. The energy of a …

Understanding the variability of galaxy star formation histories (SFHs) across a range of time-
scales provides insight into the underlying physical processes that regulate star formation …

Nudging is an important data assimilation technique where partial field measurements are
used to control the evolution of a dynamical system and/or to reconstruct the entire phase …

It is known that rapidly rotating turbulent flows are characterized by the emergence of
simultaneous upscale and downscale energy transfer. Indeed, both numerics and …

Helicity is a topological invariant that measures the linkage and knottedness of lines, tubes,
and ribbons. As such, it has found myriads of applications in astrophysics, fluid dynamics …

Predicting the fine and intricate details of a turbulent flow field in both space and time from a
coarse input remains a major challenge despite the availability of modern machine learning …

We study freely decaying quantum turbulence by performing high-resolution numerical
simulations of the Gross-Pitaevskii equation (GPE) in the Taylor-Green geometry. We use …

We investigate experimentally stratified turbulence forced by waves. Stratified turbulence is
present in oceans and it is expected to be dominated by nonlinear interaction of internal …

We report experimental results on nonlinear wave coupling in surface wave turbulence on
water at scales close to the crossover between surface gravity waves and capillary waves …
