Optimal Transport Reconstruction of Biased Tracers in Primordial Non-Gaussian Fields
Farnik Nikakhtar, Ravi K. Sheth, Nikhil Padmanabhan +2
Optimal transport provides an efficient method to infer the displacement of objects by mapping their initial positions to their present-day locations over cosmic time; equivalently…
Protohalos and their connection to halo assembly, shape and structure
Farnik Nikakhtar, Daisuke Nagai, Marcello Musso +1
Protohalos, primordial regions in the initial cosmic density field that evolve into dark matter halos, are crucial for understanding cosmic structure formation. Motivated by the po…
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…
