Luminous mass profile for MW

[adampbeardsley]

Would be good to have a quick-and-easy luminous mass profile to compare our measurements with.
Not super well known, but we can probably come up with a reasonable summary of various models.
Here's a paper that explores a bunch:

Building a model

Starting with Lin & Li, 2019: https://academic.oup.com/mnras/article/487/4/5679/5521223
They are looking at dark matter profiles and use a bunch of luminous matter models to compare. I’m going to look at their fiducial set of luminous models.

Based on Zheng et al 2001: https://iopscience.iop.org/article/10.1086/321485
Used M dwarf counts and mass-luminosity functions, based on HST

Omg, this model is gross. It’s not crazy, but they model different media (molecular, atomic, ionized, etc) individually, then add together at the end. Gross.

I'm giving up for now

My takeaway so far is that there is not yet a consensus on the baryonic mass profile of the milky way, and some models don't even need dark matter out to the sun and beyond (e.g. https://arxiv.org/pdf/1612.07781 note I don't actually believe that paper, just an example). So for now I'm not sure this is the direction we want to go.
