Abstract

The subject of this review is the central 100 parsecs of our Galaxy, with a strong focus on the central few parsecs. Observations of the electromagnetic spectrum over 13 orders of magnitude in wavelength show a broad range of phenomena involving a number of physical processes. We discuss the stellar and interstellar components, the importance of magnetic and gravitational forces, the evidence for stellar formation and a central massive black hole, and the origin and nature of ionization, outflows and interstellar gas dynamics.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Within the ionized cavity, different streams spiral in toward Sgr A* with the closest approach at ~0.04 pc where the mass inflow rate is estimated to be ~10^-3 M⊙/yr.

    “Within the ionized cavity, different streams spiral in toward Sgr A ∗ with the closest approach at ∼ 0 . 04 pc where the mass inflow rate is estimated to be ∼ 10 -3 M ⊙ yr -1 (Genzel et al. 1994).”

    From The Fermi/eROSITA bubbles: a look into the nuclear outflow from the Milky Way (2024) · cites this paper as Genzel et al. 1994

    Section 4.4 describes ionized mini-spiral streamers orbiting the centre near Sgr A*. Section 6.4 gives an influx of 10^-3–10^-2 solar masses per year into the central few parsecs, not a rate at a closest approach of 0.04 pc. The paper also suggests stellar winds may prevent gas from falling into the central 0.1 pc; the quoted closest approach and associated inflow rate are not supported. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
