Beyond UVJ: More Efficient Selection of Quiescent Galaxies With UV / Mid-IR Fluxes

Understand

The UVJ color-color diagram is a popular and efficient method to distinguish between quiescent and star-forming galaxies through their rest-frame $U-V$ vs.

• $V-J$ colors.
• Here we explore the information content of this color-color space using the Bayesian inference machine Prospector.
• We fit the same physical model to two datasets: (i) UVJ fluxes alone, and (ii) full UV-mid IR (MIR) broadband SEDs from the 3D-HST survey.
