populations of exoplanets and binary stars

... positive rates in Kepler data. He is working on vetting true exoplanet candidates (that is, making decisions about individual systems) and also modeling jointly the exoplanet and binary-star populations. We discussed various issues in all of this. Morton's current goal is to underst

Kant was wrong?

... and lower resolution data than anyone imagined. Now we have to make this case in such a way that we influence future projects!Late in the day, Juna Kollmeier (OCIW) gave a talk at the Simons Foundation. She gave a wide-ranging talk, about gravity from large scales to black holes. The questions were all about Einstein

fitting with upper limits, stars in accretion disks

... strategy of getting the data provider to replace the upper limits with forced measurements (who said measurements have to deviate significantly from zero to be useful?) to the ur-Bayesian strategy of including the miss

a new kind of photometric redshift

Boris Leistedt came by for an hour to discuss his progress on huge-survey photometric redshift determination. His method is truly novel: It is not a template-based method in the traditional sense, but it is also not a machine-learning method of the train-and-test variety (supervised regression, like Random Forest or equivalent): It uses the causal and noise model of a template method, but fits for the details of every one of the set of templates and also the luminosity functions for the galax
