Context

  • Putting up a bit of "checkpoint" bullet here, as well as some additional investigations into the offset we are seeing with the K-band stellar mass estimates.

Diagnostics

K-band and M/L Relation Testing

  • First, here's a quick visual comparison of the Cappellari vs. LM24 K-band relation, as well as a few of the ML relations I'm playing around with below:
K-band Relation ML Relations
  • And as one other quick sanity check, here's a quick calculation of the M_K based stellar mass from Cappellari vs LM24:
One-to-One Histograms
  • I then computed the mass from all methods and both K-band relations, and have a comparison of each pair of results here:
    • Note that the "fiducial" results up to now are the Cluver14_clipped results, but all of the mass estimation methods appear to be qualitatively similar:
    • Also, at least to my eye, it's not as simple as picking one method vs. the other; the K-band measurements all appear to be systematically higher, and this differences seems to get worse with increasing redshift:

Difference vs. Redshift

Checking the MM13 Sample Only

  • I've taken out the MM13 sources that I was able to find ~50 of them (need to double check the matching to be a little more careful, but this should be a ~reliable sample of points).
    • I need to spot check a few of the points which apparently don't have K-band measurements in 2MPZ (but again, need to double check where these might have disappeared to).
    • Regardless, here's the results of the different mass prescriptions applied to the K-band and WISE W1/W2 data:

Checking the vdb+16 sample

  • I've also taken the vdb+16 sample of BHs, and computed the stellar mass from the K-band and the W1/W2 magntiudes for a comparison of these sources:
Mass Comparison Redshift Comp

Some literature results I've come across

  • Utilizing stellar mass estimates to identify gravitational wave host galaxies
    • Probably the most similar set of results to ours -- they compare a variety of different photometric stellar mass estiamtes to the GAMA SED results, as well as Cappellari's method.
    • "We observed that the methods using WISE magnitudes (Jarrett’s, Cluver’s, and Kettlety’s) tend to underestimate the M∗ values for massive galaxies (M∗ > 1010 M), whereas this trend is less pronounced for Cappellari’s method."

GAMA Stellar vs Dyanmical Result

  • On the Masses of Galaxies in the Local Universe

    • Direct comparison of dynamical vs "stellar" masses for a sample of galaxies which appear to be qualitatively similar to our results
    • Could maybe be that the M_K relation is fit to dynamical masses, whereas the WISE W1 and W2 are calibrated to SED masses?

  • Photometric versus dynamical stellar masses and their impact on scaling relations in nearby disc galaxies

    • Seems to find a ~0.05 dex offset between dynamical and photometric stellar masses, with dynamical being slightly higher on average.

  • Other thoughts

    • Is there some implicit assumption about the IMF between the W1/W2 mass calibration and the other calibrations? For example, the GAMA stellar masses that are used to calibrate the W1 and W2 masses assume a Chabrier 2003 IMF, and apparently the net effect is that converting a Salpeter-based mass to Chabrier-based mass increases the mass by a factor of ~1.8, or about 0.25 dex. Still trying to figure out if this is relevant for our work; as I said, GAMA calibrates with a Chabrier IMF
