We derive the extinction curve towards the Galactic Center from 1 to 19 micron. We use hydrogen emission lines of the minispiral observed by ISO-SWS and SINFONI. The extinction free flux reference is the 2 cm continuum emission observed by the VLA. Towards the inner 14" * 20" we find an extinction of A(2.166 micron)=2.62 +/- 0.11, with a power-law slope of alpha=-2.11 +/- 0.06 shortward of 2.8 micron, consistent with the average near infrared slope from the recent literature. At longer wavelengths, however, we find that the extinction is grayer than shortward of 2.8 micron. We find it is not possible to fit the observed extinction curve with a dust model consisting of pure carbonaceous and silicate grains only, and the addition of composite particles, including ices, is needed to explain the observations. Combining a distance dependent extinction with our distance independent extinction we derive the distance to the GC to be R_0=7.94 +/- 0.65 kpc. Towards Sgr A* (r<0.5") we obtain A_H=4.21 +/- 0.10, A_Ks=2.42 +/- 0.10 and A_L'=1.09 +/- 0.13.

  1. Binary disruptions driven by massive disks around massive black holes

    astro-ph.GA 2026-07 conditional novelty 6.0 of 10

    Disk torques can drive stellar binaries around a massive black hole to tidal disruption, and the Milky Way's young stellar disk likely caused ~10^2 such events ~5 Myr ago.

  2. Theoretical Predictions for the Inner Dark Matter Distribution in the Milky Way Informed by Simulations

    hep-ph 2025-01 conditional novelty 6.0 of 10

    The Milky Way's inner dark matter density slope is predicted to lie between -0.5 and -1.3, and the 5-degree J-factor range is 0.8-30 x 10^23 GeV^2/cm^5.
