Basis function expansions of the two-point correlation function and reconstruction of the cosmological distance scale
Fatima Abd Alrahman, Farnik Nikakhtar, Marcello Musso +2
The shape of the correlation function of galaxy pairs can be used as a cosmological distance indicator. Most estimators of this shape require that one bin the pair counts, and cons…

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…
