  • The majority of low-eccentricity stars with high [Mg/Fe], low metallicity, and retrograde motions identified by Mackereth et al. (2019) overlap with those from Thamnos.

    “The majority of the low-eccentricity stars with high [Mg/Fe], low metallicity, and retrograde motions identified by Mackereth et al. (2019) overlap with those from Thamnos.”

    From Streams, Substructures, and the Early History of the Milky Way (2020) · cites this paper as Mackereth et al. (2019)

    Section 3.2 (pp. 10–11) identifies low-eccentricity stars on retrograde orbits, and Section 3.1.2 (p. 9) reports that the low-eccentricity group has relatively higher [Mg/Fe]. The paper does not identify these stars as Thamnos or establish that a majority overlap with it. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • The lower-energy region with stars of low eccentricity and high [Mg/Fe] would be associated with Thamnos.

    “In either case, the lower-energy region, with stars of low eccentricity and high [Mg/Fe] identified by Mackereth et al. (2019) and Koppelman et al. (2019a), would be associated with Thamnos.”

    From Streams, Substructures, and the Early History of the Milky Way (2020) · cites this paper as Mackereth et al. (2019)

    Mackereth et al. identify a low-eccentricity halo group with slightly higher [Mg/Fe] than the high-eccentricity group (Section 3, p. 6; Section 3.1.2, p. 9). The passages do not establish that this group occupies a lower-energy region. The association with Thamnos is phrased as the citing authors’ inference, not as a finding attributed to Mackereth et al. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • Our predicted accretion redshifts largely satisfy the constraints obtained through independent methods.

    “Relative to other measurements in the literature, our predicted accretion redshifts largely satisfy the constraints obtained through independent methods.”

    From Kraken reveals itself – the merger history of the Milky Way reconstructed with the E-MOSAICS simulations (2020) · cites this paper as Mackereth et al. (2019)

    The Summary and Conclusions (p. 15) compare the paper’s EAGLE-based estimate of an accretion around 8–9 Gyr ago with Helmi et al.’s estimate of approximately 10 Gyr ago, describing the timescales as potentially consistent. This supports a qualified comparison with an independent estimate, but the paper cannot establish that the citing authors’ own predicted accretion redshifts largely satisfy constraints from independent methods generally. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • A similar amplitude mean retrograde motion has been reported by Mackereth et al. (2019) using APOGEE distances.

    “A similar amplitude mean retrograde motion has been reported by Mackereth et al. (2019) using APOGEE distances.”

    From Streams, Substructures, and the Early History of the Milky Way (2020) · cites this paper as Mackereth et al. 2019

  • Mackereth et al. (2019) provide an upper limit on the accretion redshift of z_acc < 1.5 (or t_acc < 9.5 Gyr).

    “Mackereth et al. (2019) provide an upper limit on the accretion redshift of z acc &lt; 1 : 5 (or t acc &lt; 9 : 5 Gyr).”

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.
