The Universality of Dark Matter Density Profiles for Milky Way Analog Galaxies
Maria Clara Cavalcante-Siviero, K. Menéndez-Delmestre, P. P. B. Beaklini +4
The structure, extent, and mass of the Milky Way's (MW) dark matter (DM) halo are observationally challenging to determine due to our position within the Galaxy. To overcome this l…
Scale-dependent and background-preserving gravity from an action: cosmological tests
Wiliam S. Hipólito-Ricaldi, Rodrigo von Marttens, Felipe de Melo-Santos +1
We investigate the observational implications of a gravitational model wherein the gravitational constant and the cosmological constant exhibit scale-dependent behavior at…
Cosmological coupling of local gravitational systems
Mariano Cadoni, Mirko Pitzalis, Davi C. Rodrigues +1
We investigate the cosmological coupling of spherical, local astrophysical systems. We derive a general formula quantifying the cosmological coupling of the Misner-Sharp mass of th…
Dark matter distribution in Milky Way-analog galaxies
Natanael G. de Isídio, K. Menéndez-Delmestre, T. S. Gonçalves +9
Our current understanding of how dark matter (DM) is distributed within the Milky Way halo, particularly in the solar neighborhood, is based on either careful studies of the local…
