The role of energy shear in the collapse of protohaloes
Marcello Musso, Ravi K. Sheth
Dark matter haloes form from the collapse of matter around special positions in the initial field, those where the local matter flows converge to a point. For such a triaxial colla…

The energy shear of protohaloes
Marcello Musso, Giulia Despali, Ravi K. Sheth
As it collapses to form a halo, the shape of a protohalo patch is deformed by the initial shear field. This deformation is often modeled using the "deformation" tensor, constructed…
