Abstract

We present a catalog of 422 galaxies with published measurements of their globular cluster (GC) populations. Of these, 248 are E galaxies, 93 are S0 galaxies, and 81 are spirals or irregulars. Among various correlations of the total number of GCs with other global galaxy properties, we find that N GC correlates well though nonlinearly with the dynamical mass of the galaxy bulge , where σ e is the central velocity dispersion and R e the effective radius of the galaxy light profile. We also present updated versions of the GC specific frequency S N and specific mass S M versus host galaxy luminosity and baryonic mass. These graphs exhibit the previously known U-shape: highest S N or S M values occur for either dwarfs or supergiants, but in the midrange of galaxy size (10 9 –10 10 L ☉ ) the GC numbers fall along a well-defined baseline value of S N ≃ 1 or S M = 0.1, similar among all galaxy types. Along with other recent discussions, we suggest that this trend may represent the effects of feedback, which systematically inhibited early star formation at either very low or very high galaxy mass, but which had its minimum effect for intermediate masses. Our results strongly reinforce recent proposals that GC formation efficiency appears to be most nearly proportional to the galaxy halo mass M halo . The mean "absolute" efficiency ratio for GC formation that we derive from the catalog data is M GCS / M halo = 6 × 10 −5 . We suggest that the galaxy-to-galaxy scatter around this mean value may arise in part because of differences in the relative timing of GC formation versus field-star formation. Finally, we find that an excellent empirical predictor of total GC population for galaxies of all luminosities is N GC ∼ ( R e σ e ) 1.3 , a result consistent with fundamental plane scaling relations.

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.
