What are the impacts of dark matter? 


Best insight from top research papers

The impacts of dark matter (DM) are explored in several studies. DM affects the properties of neutron stars (NSs), including the mass-radius relation, moment of inertia, and tidal deformability. It softens the equation of state (EOS) and has marginal effects on nuclear matter properties, except for the EOSs and binding energy per particle . DM can accumulate inside NSs, making them unstable, and the secondary component of a binary system might be a NS with DM content . DM also affects the oscillations of hyperon stars and has a correlation with the tidal deformability parameter . In the context of galaxy formation, DM has dominant impacts and influences the formation of dark matter halos . Additionally, DM affects NSs with antikaon condensations, altering their properties and neutrino emission features . The presence of DM inside NSs affects their curvatures and binding energy .

Can star velocity at halo trace dark matter distribution?
4 answers
Metal-poor stars in the Milky Way halo can effectively trace the local dark matter velocity distribution, indicating a common origin. These stars, along with other halo tracers, are influenced not only by the Milky Way itself but also by satellites like the Large Magellanic Cloud, leading to large-scale kinematic patterns in the stellar halo. Recent studies have shown that specific populations of stars, such as M giants, can be sensitive to rare, massive accretion events, providing insights into the local dark matter distribution. Weak gravitational lensing analyses have also revealed that the lensing signal around galaxies is closely related to their velocity dispersion, shedding light on the projected distribution of dark matter. Therefore, star velocities in the halo can indeed serve as valuable tracers of the underlying dark matter distribution.
What is the dark matter radial profile of milky way?
5 answers
The dark matter radial profile of the Milky Way has been extensively studied using various methods. Recent research has shown that the Milky Way's dark matter density profile can be better described by a cored Einasto profile with a slope parameter of $0.91^{+0.04}_{-0.05}$, rather than a generalized Navarro-Frenk-White (NFW) profile. Additionally, investigations utilizing cosmological simulations have highlighted the importance of the "splashback" radius in delineating the outer boundary of the dark matter halo, with significant scatter observed in the velocity dispersion profiles of dark and luminous tracers within Milky Way-mass halos. Furthermore, a non-parametric method has been developed to directly infer the dark matter contribution to the circular velocity across the Galaxy, allowing for a clean determination of the dark matter profile without theoretical bias.
What is the first paper suggesting the drift flux model?
5 answers
The first paper proposing the drift flux model was by Woo Il Lee and Paulo J. Waltrich. Their study introduced a drift-flux model for upward two-phase high-velocity flow in large diameter pipes, specifically focusing on Worst-Case-Discharge (WCD) calculations for offshore wells. Unlike other models, their proposed model does not exhibit sudden pressure surges or reductions during flow regime transitions and does not rely on fixed drift-flux coefficients for each flow regime. The model was validated across a wide range of experimental and field data, showcasing the lowest average absolute pressure error and standard deviation compared to other models. This pioneering work laid the foundation for further advancements in drift-flux modeling for two-phase flow systems.
