A Bayesian approach to calibrating period-luminosity (PL) relations has substantial benefits over generic least-squares fits. In particular, the Bayesian approach takes into account the full prior dis...
A Mid-Infrared Indicator for Total Infrared Luminosity and Star Formation Rate of Local and High-Redshift Galaxies

We present a new method to use 24 micron observations to estimate the total infrared luminosity, LIR, and the star formation rate of star-forming galaxies across the redshift range 0 < z < 3. This is ...

We obtained 13 epochs of mid-infrared interferometry with the MIDI instrument at the VLTI between April 2004 and July 2007, covering pulsation phases 0.45-0.85 within four cycles. The data are modeled...
