Agama is a publicly available software library for a broad range of applications in the field of stellar dynamics. It provides methods for computing the gravitational potential of arbitrary analytic density profiles or N-body models; orbit integration and analysis; transformations between position/velocity and action/angle variables; distribution functions expressed in terms of actions and their moments; iterative construction of self-consistent multicomponent galaxy models. Applications include the inference about the structure of Milky Way or other galaxies from observations of stellar kinematics; preparation of equilibrium initial conditions for N-body simulations; analysis of snapshots from simulations. The library is written in C++, provides a Python interface, and can be coupled to other stellar-dynamical software: Amuse, Galpy and Nemo.

  1. Dark Matter in Draco and Bo\"otes I: Hints of a Core in an Ultra-Faint Dwarf from Simulation-Based Inference

    astro-ph.GA 2026-06 unverdicted novelty 7.0

    GraphNPE recovers a significantly lower central density for Boötes I consistent with a core while Draco remains marginally cuspy, and demonstrates that higher-order velocity moments reduce bias in dynamical modeling.

  2. Rogue Ones: Orbital census of Galactic Cepheids and their Anomalies

    astro-ph.GA 2026-06 unverdicted novelty 7.0

    A 6D kinematic census identifies 18 anomalous Cepheids with extreme orbits, including one possibly scattered by globular cluster E3, and finds consistency between dynamical and stellar ages.

  3. TDEs on FIRE: Illuminating the Cosmic Evolution of Tidal Disruption Rates

    astro-ph.HE 2026-06 unverdicted novelty 7.0

    FIRE-2 simulations show per-galaxy tidal disruption rates peak near z=2.5 at 4e-4 per year, correlate with SFR and central density, and remain high in satellite galaxies at early times.

  4. Reconstructing the Stripping History of the Sagittarius Stream with Neural Networks

    astro-ph.GA 2026-05 unverdicted novelty 7.0

    A neural network trained on simulations infers stripping times for Sagittarius stream stars from phase-space data, measuring a 0.3 dex/Gyr metallicity gradient and estimating ages for globular clusters such as Pal 12 ...

  5. SchwarMAX: a GPU-friendly Schwarzschild orbit-superposition modelling framework

    astro-ph.GA 2026-06 unverdicted novelty 6.0

    SchwarMAX delivers a fast GPU-native Schwarzschild modeling code that recovers density profiles and bar pattern speed from mock IFU data of a simulated barred galaxy.

  6. Self-interacting dark matter promotes bar formation in disk galaxies

    astro-ph.GA 2026-06 unverdicted novelty 6.0

    SIDM halos accelerate bar formation and growth in disk galaxies through enhanced angular momentum exchange, independent of core formation.

  7. The Hubble Missing Globular Clusters Survey IV. Ultra-faint compact satellites of the Milky Way. The case of Koposov 2

    astro-ph.GA 2026-06 unverdicted novelty 6.0

    Koposov 2 is shown to be an old (13.7 Gyr) star cluster with half-light radius 2.7 pc, absolute magnitude -0.95, and stellar mass 372 solar masses, supporting a star cluster classification over a dwarf galaxy.

  8. When bars and spirals conspire: recurrent build-up of the nuclear regions of disc galaxies

    astro-ph.GA 2026-06 unverdicted novelty 5.0

    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.

  9. The VMC survey -- LV. The coherent expansion of the SMC

    astro-ph.GA 2026-06 unverdicted novelty 4.0

    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.
