Hertzsprung patterns on involutions
Marilena Barnabei, Niccolò Castronuovo, Matteo Silimbani
Hertzsprung patterns, recently introduced by Anders Claesson, are subsequences of a permutation contiguous in both positions and values, and can be seen as a subclass of bivincular…
Multi-centered dilatations, congruent isomorphisms and Rost double deformation space
Arnaud Mayeux
We introduce multi-centered dilatations of rings, schemes and algebraic spaces, a basic algebraic concept. Dilatations of schemes endowed with a structure (e.g. monoid, group or Li…
Imprint of DES super-structures on the Cosmic Microwave Background
A. Kovács, C. Sánchez, J. García-Bellido +58
Small temperature anisotropies in the Cosmic Microwave Background can be sourced by density perturbations via the late-time integrated Sachs-Wolfe effect. Large voids and superclus…
The chaotic four-body problem in Newtonian gravity I: Identical point-particles
Nathan W. C. Leigh, Nicholas C. Stone, Aaron M. Geller +4
In this paper, we study the chaotic four-body problem in Newtonian gravity. Assuming point particles and total encounter energies 0, the problem has three possible outcomes.…
Magnetic flux stabilizing thin accretion disks
Aleksander Sadowski
We calculate the minimal amount of large-scale poloidal magnetic field that has to thread the inner, radiation-over-gas pressure dominated region of a thin disk for its thermal sta…
Relativistic effects on tidal disruption kicks of solitary stars
Emanuel Gafton, Emilio Tejeda, James Guillochon +2
Solitary stars that wander too close to their galactic centres can become tidally disrupted, if the tidal forces due to the supermassive black hole (SMBH) residing there overcome t…
