Dark Matter at the Center and in the Halo of the Galaxy [PDF]
, 2004 All presently known stellar-dynamical constraints on the size and mass of the supermassive compact dark object at the Galactic center are consistent with a ball of self-gravitating, nearly non-interacting, degenerate fermions with mass between 76 and 491 keV, for degeneracy factor g=2. Sterile neutrinos of 76 keV mass, which are mixed with at least one

Closing the Gap between Observed Low-mass Galaxy H i Kinematics and Cold Dark Matter Predictions
The Astrophysical JournalTesting the standard cosmological model (ΛCDM) at small scales is challenging. Galaxies that inhabit low-mass dark matter halos provide an ideal test bed for dark matter models by linking observational properties of galaxies at small scales (low mass ...

Halo Properties from Observable Measures of Environment: I. Halo and Subhalo Masses
The Open Journal of Astrophysics, 2023 The stellar mass - halo mass relation provides a strong basis for connecting galaxies to their host dark matter halos in both simulations and observations.

Ecology and Evolution, Volume 16, Issue 9, September 2026.IUCN‐defined extant distribution of the Indo‐Pacific finless porpoise (Neophocaena phocaenoides), overlaid with occurrence records, global Marine Protected Areas (MPAs), and Important Marine Mammal Areas (IMMAs). ABSTRACT Prior to this study, the narrow‐ridged finless porpoise (Neophocaena asiaeorientalis) had been extensively studied across East Asia,

Unveiling the Functional Role of KIF21B in Microglia Inflammatory Response
Glia, Volume 74, Issue 9, September 2026.Microglia express KIF21B in both sexes. KIF21B binds to microglia cytoskeleton; inflammation alters such interaction promoting a phagocytic state in females. In male microglia KIF21B modulates migration. ABSTRACT Microglia are brain immune cells that maintain homeostasis and respond to injury, changing cell morphology to drive inflammation, migration ...

The clustering of galaxies in hierarchical galaxy formation models [PDF]
, 2010 Galaxy clustering encodes information about the values of cosmological parameters and also about the physical processes behind galaxy formation and evolution. The GALFORM semi-analytical model is the theoretical approach we used to model galaxy formation.

The Cherenkov Radiation in the Galaxy’s Halo of Dark Matter
International Journal of Astronomy and Astrophysics, 2013 The effect of light refraction in a galaxy halo of dark matter, described by profiles of Navarro-Frenk-White and Burkett, was considered. Powers of the Cherenkov radiation for the refractive indexes of gravitational fields with these profiles were calculated.
