Abstract

We model the effects of repeated supernova (SN) explosions from starbursts in dwarf galaxies on the interstellar medium of these galaxies, taking into account the gravitational potential of their dominant dark matter halos. We explore SN rates from one every 30,000 yr to one every 3 Myr, equivalent to steady mechanical luminosities of L =0.1-10 × 10 38 ergs s −1 , occurring in dwarf galaxies with gas masses M g =10 6 -10 9 M ☉ . We address in detail, both analytically and numerically, the following three questions: 1. When do the SN ejecta blow out of the disk of the galaxy? 2. When blowout occurs, what fraction of the interstellar gas is blown away, escaping the potential of the galactic halo? 3. What happens to the metals ejected from the massive stars of the starburst? Are they retained or blown away?

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

  • The molecular gas could have been advected upwards by a shock or advected up and then slid down along the edge of the shock surrounding a super-bubble.

    “The molecular edge in the north-western side encapsulates the radio emission, suggesting that the molecular gas could have been advected upwards by a shock (Walch et al. 2015) or advected up and then slid down along the edge of the shock surrounding a super-bubble (Suchkov et al. 1994; Mac Low & Ferrara 1999; Roy et al. 2016).”

    From The Fermi/eROSITA bubbles: a look into the nuclear outflow from the Milky Way (2024) · cites this paper as Mac Low & Ferrara 1999

    Section 5.1 (page unavailable) describes a rising superbubble surrounded by a cold shell of swept-up gas, which supports the upward-transport part of the proposed mechanism. It does not identify that gas as molecular or describe it sliding down along the shock’s edge. (LLM, conf=0.78)

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.
