The Dependence of Dark Matter Halo Properties on the Morphology of Their Central Galaxies from Weak Lensing

The Astrophysical Journal
Xu & Jing reported a monotonic relationship between the host halo mass M _h and the morphology of massive central galaxies, characterized by the Sérsic index n , at fixed stellar mass, suggesting that morphology could serve as a good secondary proxy for ...

Chameleon gravity as an alternative to dark matter

European Physical Journal C: Particles and Fields
By studying the chameleon gravity on galaxy scales, we investigate the effects of the chameleon dark matter. To perform this task, we consider the dynamics of the chameleon scalar field in the region of galactic halos in static spherically symmetric ...

Hydro-Gravitational Dynamics of Planets and Dark Energy

Journal of Applied Fluid Mechanics, 2009
Self gravitational fluid mechanical methods termed hydro-gravitational-dynamics (HGD) predict plasma fragmentation 0.03 Myr after the turbulent big bang to form protosuperclustervoids, turbulent protosuperclusters, and protogalaxies at the 0.3 Myr ...

Halo Asymmetry in the Modeling of Galaxy Clustering

The Astrophysical Journal
Conventional studies of galaxy clustering within the framework of halo models typically assume that the density profile of all dark matter halos can be approximated by the Navarro–Frenk–White (NFW) spherically symmetric profile.
