COZMIC. III. Cosmological Zoom-in Simulations of Self-interacting Dark Matter with Suppressed Initial Conditions

The Astrophysical Journal
We present eight cosmological dark matter (DM)-only zoom-in simulations of a Milky Way–like system that include suppression of the linear matter power spectrum P ( k ), and/or velocity-dependent DM self-interactions, as the third installment of the ...

The “Little Dark Dot”: Evidence for Self-interacting Dark Matter in the Strong Lens SDSS J0946+1006?

The Astrophysical Journal
Previous studies, based on precise modeling of a gravitationally lensing image, have identified what may be an extremely compact, dark perturber in the well-known lensing system SDSS J0946+1006 (the “Jackpot”).

Relation between the Local Width and Linear Halo Mass Density of Cosmic Filaments

The Astrophysical Journal
Large-scale cosmic filaments may have played an important role in shaping the properties of galaxies. Meanwhile, cosmic filaments are believed to harbor a substantial portion of the missing baryons at redshift z < 2.

The Tidal Torque Theory Revisited. I. Protohalo Angular Momentum

The Astrophysical Journal
In tidal torque theory, the angular momentum (AM) of dark matter halos arises from the tidal torque suffered by aspherical collapsing patches due to surrounding mass fluctuations.
