One acceleration measurement equals ~10^5 phase-space measurements for local dark matter density estimation, with acceleration outperforming Jeans modeling in both equilibrium and perturbed Milky Way simulations.
Idealized simulations with live gas particles show the LMC corona's present-day velocity and column density profiles match a first-passage orbit but are too low in a second-passage orbit, yielding truncation radii of 16.6 kpc versus 5.7 kpc and strongly disfavoring the latter.
Boötes III has σ_v ≈ 1.7 km/s, a recent ~9.5 kpc pericenter on a polar eccentric orbit, and is actively tidally disrupting, with debris broadly consistent with the Styx stream.
GalPort computes multi-timescale action-angle variables and orbital classifications for evolving barred galaxy simulations, with specialised bar phase-space analysis tools.
PHANTOM is a public MATLAB/Octave toolbox for linear field statistics and halo observables in dark matter cosmology, validated to sub-percent agreement with Python packages colossus, hmf, and halomod.
A PINN approach learns galactic gravitational potentials from acceleration data, achieving sub-percent errors on simulations while outperforming analytic models and retaining interpretability via structured priors.
PRFM-vol is a new subgrid star formation model for cosmological simulations that computes SFR from ambient densities via PRFM theory and a modified effective EOS, producing taller stellar scale heights, slightly higher stellar mass, and morphology changes including Toomre-driven clumps compared to p
In a barred Milky Way-mass simulation, the nuclear star cluster and nuclear disk co-evolve and share a star-formation history, except for a single massive cluster merger.
Mutual information analysis of TNG50 simulations shows gravitational potential and total energy retain merger mass and infall time information longest, while radial velocity loses it within ~5 Gyr, with washout depending on radius, merger age, and mass.
ArkenstoneBH is a new subgrid model for the hot phase of black hole feedback that, in isolated galaxy tests, suppresses star formation by counteracting gas inflows from the circumgalactic medium.
In cool-core cluster simulations, mixing with pre-existing cold gas, not direct radiative cooling, dominates condensation; magnetic fields stretch the pre-condensation history to ~150 Myr and brake infalling clouds through tension.
3D simulations show gas can vault over nuclear rings in barred galaxies via vertical momentum, delivering outer gas to the central region.
Milky Way-mass dark matter density profiles in IllustrisTNG are largely insensitive to astrophysics and cosmology variations, dominated by halo-to-halo variance instead.
300S stellar stream exhibits three density peaks, smooth width variations, a possible 4.7 degree gap, and a kink modeled as resulting from Large Magellanic Cloud interaction across its full known footprint.
Non-Gaussian LSF shapes bias kinematic extraction from spectra; matching the LSF of templates to the target reduces dispersion bias below 1%.
N-body+hydro simulation of an isolated Milky Way-like galaxy shows bar-spiral reconnections produce episodic star formation bursts in nuclear stellar discs and clusters after the initial bar-driven burst.
Power-law modeling of gas mass fraction and temperature variation reconciles observed X-ray scaling relations in galaxy clusters, reducing >3σ tensions from 49% to 11% and yielding a redshift-independent mass proxy Y_LGT0.
Simulations of evolving galaxies show strong L_nu-SFR and L_nu-V_rot correlations up to z~3, with turbulent magnetic fields dominating at low redshift and large-scale fields growing in importance at higher redshift.
Next-generation IFU instruments could detect core scouring and tangential anisotropy from MBH binaries up to z~0.14 for ~150 pc cores and higher redshifts for larger cores, expanding searchable volume by 30-40 times including lower-mass systems.
Parameter scans of a hand-set effective model show that adding dark matter around a rotating black hole slows the intermediate-axis flip frequency of a coherent triaxial structure relative to Kerr.
Improved VMC proper motions show SMC expansion along SE-NW axes consistent with LMC tides, radial inward motions with no rotation, and northward motion in older RGB stars from a prior interaction.
Bayesian comparison of Gaia DR3 rotation curves favors the Einasto dark matter profile over NFW, prefers cored over cuspy profiles, and finds MOND variants provide poorer fits than the best dark matter models.
Interstellar objects may contribute enough baryonic mass to reduce the local dark matter halo density to 0.24 GeV/cm³.
