Astronomical observations reveal a major deficiency in our understanding of physics—the
detectable mass is insufficient to explain the observed motions in a huge variety of systems …

We use a compilation of disc galaxy rotation curves to assess the role of the luminous
component ('baryons') in the rotation curve diversity problem. As in earlier work, we find that …

It is commonly believed that galaxies use, throughout Hubble time, a very small fraction of
the baryons associated with their dark matter halos to form stars. This so-called low star …

We compare proposed solutions to the core vs cusp issue of spiral galaxies, which has also
been framed as a diversity problem, and demonstrate that the cuspiness of dark matter halos …

The cuspy central density profiles of cold dark matter (CDM) haloes make them highly
resilient to disruption by tides. Self-interactions between dark matter particles, or the cycling …

Modified Newtonian dynamics (MOND), postulating a breakdown of Newtonian mechanics
at low accelerations, has considerable success at explaining galaxy kinematics. However …

Neutrino detectors participate in the indirect search for the fundamental constituents of dark
matter (DM) in form of weakly interacting massive particles (WIMPs). In WIMP scenarios …

We explore the predictions of Milgromian gravity (MOND) in the local universe by
considering the distribution of the" phantom" dark matter (PDM) that would source the MOND …

In ΛCDM cosmology, to first order, galaxies form out of the cooling of baryons within the virial
radius of their dark matter halo. The fractions of mass and angular momentum retained in the …

Context. Disc-halo decompositions z= 1− 2 star-forming galaxies (SFGs) at z> 1 are often
limited to massive galaxies (M⋆> 10 10 M⊙) and rely on either deep integral field …
