Tilted Dark Halos Are Common and Long-lived, and Can Warp Galactic Disks
The Astrophysical Journal Letters, 2023 In the Lambda cold dark matter paradigm, the dark halo governs the gravitational potential within which a galaxy can form and evolve. In this Letter we show that the present-day inner ( r < 50 kpc) dark halo can be significantly misaligned with the ...

Chemie Ingenieur Technik, EarlyView., 2023 Let us consider an alternative perspective on climate change: The sum of solar radiation and heat generated by human activity result in a net energy input of 1.96 times that of the Sun on the Earth's surface. The expanding global population is expected to exacerbate this issue. Potential solutions are proposed, including replacement and heat recycling.

COLD DARK MATTER SUBSTRUCTURES IN EARLY-TYPE GALAXY HALOS [PDF]
The Astrophysical Journal, 2016 ABSTRACT We present initial results from the “Ponos” zoom-in numerical simulations of dark matter substructures in massive ellipticals. Two very highly resolved dark matter halos with M vir = 1.2 × 1013 and M vir = 6.5 ×

The Astrophysical Journal, 2023 Constraining the distribution of small-scale structure in our universe allows us to probe alternatives to the cold dark matter paradigm. Strong gravitational lensing offers a unique window into small dark matter halos (

Self-gravitating strange dark matter halos around galaxies [PDF]
Physical Review D, 2020 A new family of nonrelativistic, Newtonian, non-quantum equilibrium configurations describing galactic halos is introduced, by considering strange quark matter conglomerates with masses larger than about 8 GeV as new possible components of the dark matter.

Dark matter phenomenology of high-speed galaxy cluster collisions
European Physical Journal C: Particles and Fields, 2017 We perform a general computational analysis of possible post-collision mass distributions in high-speed galaxy cluster collisions in the presence of self-interacting dark matter.

Dark Matter Halos in Elliptical Galaxies
The Astrophysical Journal, 1993 Values of the M/L B ratio in the inner regions of elliptical (E) galaxies are determined using ionized gas disks as tracers of the triaxial potential. These data, when combined with those provided by the H I disks extending to the outer regions, show that the variation of M/L B with galactocentric radius in Es is similar to that of spirals.

The Astrophysical Journal, 2023 Galaxies show different halo scaling relations such as the radial acceleration relation, the mass discrepancy acceleration relation (MDAR), or the dark matter (DM) surface density relation.
