This paper presents a new approach to combine cross-correlation functions. The combination is based on a maximum-likelihood approach and uses a non-linear combination scheme. It can be effective for radial-velocity analysis of multi-order spectra, or for analysis of multiple exposures of the same object. Simulations are presented to show the potential of the suggested combination scheme. The technique has already been used to detect a very faint companion of HD41004.

  1. Accuracy of analytic potentials for orbits of satellites around a Milky Way-like galaxy: comparison with $N$-body simulations

    astro-ph.GA 2025-06 conditional novelty 4.0 of 10

    Analytic Milky Way potentials reproduce N-body satellite orbits to within 5% for masses up to 10^8 Msun and radii above 30 kpc, but only within the first 1 to 2 Gyr.
