Consequences of a New Hot Component of the Interstellar Medium
Abstract
The suggestion that the observed 0.25 keV X-ray background and O VI sabsorption lines are produced by a new, hot (T∼106 K), diffuse component of the medium is examined in the context of both a steady-state and a time-dependent model. It is concluded that such a component can explain the two observations only if (1) the pressure of the cooler interstellar medium is 10 times higher than the previously estimated p/k∼2000 cm-3K; (2) a mechanism such as the proposed convective-radiative "galactic fountain" exists to cool the hot gas; and (3) another component is responsible for the presence of O VI at temperatures below 106 K.

“However, ejected gas is able to rise to substantial heights in the halo and to displace infalling material, before it eventually falls back to the disk, forming a “galactic fountain” (Shapiro & Field, 1976).”

“In many formulations, the cooler low-ion traced gas precipitates out of the warmer O vitraced phase, owing to thermal instabilities (Shapiro & Field 1976; McCourt et al. 2012; Voit et al. 2015b; Thompson et al. 2016; see also Wang 1995), while the O vi-traced gas may be continually replenished by a…”

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.
