Invariant manifolds in barred galaxy simulations. III. Self-regulated weakening of strong spiral arms
T. Soler-Terricabras, S. Roca-Fà brega, M. Romero-Gómez
The paper investigates why strong spiral arms in barred galaxies weaken, showing that self‑gravitating spirals shift the galaxy’s Lagrangian points, disrupting invariant‑manifold d…
Discrepancies between Chandrasekhar's theory of relaxation and -body simulations
Kerwann Tep, Douglas C. Heggie
The paper compares Chandrasekian orbit‑averaged relaxation theory with high‑precision N‑body simulations of anisotropic globular clusters, finding reduced but still position‑depend…
Enabling Cosmic Web Analysis at Gigaparsec Scales: A Multi Block Approach for DisPerSE
Ankit Singh, Frazer Pearce, Meghan Gray +1
The paper introduces a frozen‑core, multi‑block technique that enables the DisPerSE filament finder to process gigaparsec‑scale cosmological simulations by preserving global topolo…
Tidal evolution of packed moon systems around an Earth-mass planet
Alan Briseño, Billy Quarles, Marialis Rosario-Franco
The paper uses N-body and tidal simulations to determine how many tightly packed moons of various masses can stably orbit an Earth‑mass planet, finding limits that depend on tidal…
Radial velocity statistics of cosmic voids as a probe of interacting dark energy
Kin Ho Luo, Ming-chung Chu, Kwan Chuen Chan +1
The paper uses N-body simulations to show that the radial velocity and velocity‑dispersion profiles of cosmic voids change noticeably in a Type‑3 interacting dark‑energy model, mak…
The Environmental Dependence of Halo Intrinsic Alignments: Stronger Signals in Underdense Regions
Masaya Ichikawa, Jingjing Shi, Toshiki Kurita +3
The paper investigates how the intrinsic alignment of dark matter haloes varies with large‑scale environment, finding that haloes in underdense regions show stronger alignment than…
