## More GPs for reconstructing H(z) …

It seems there’s quite a cottage industry for GP-based non-parametric modelling of H(z) using the cosmic chronometers supernova (SN) dataset: today on astro-ph we had a contribution by Verde et al., following on from Busti et al.’s effort last week. … Continue reading

## On the geometric path to a smack down …

I noticed this paper on astro ph today by Hou, Goodman, & Hogg describing their “new” idea for marginal likelihood estimation using the geometric path. A quick inspection reveals that in fact the idea being presented is exactly the same as … Continue reading

## More fine structure results …

Another brief paper on astro ph today looking at the fine structure constant: Rahmani et al. Instead of using the many multiplet method of Dzuba et al & Webb et al—which (if there are no systematic errors) can estimate da/a … Continue reading

## ABC for stellar population inference in low mass star clusters …

I had a productive email exchange with Miguel Cervino (who wrote this review of the challenges for stellar population parameter inference under the stochastic effects of IMF sampling in low mass star clusters) regarding the potential for ABC in this … Continue reading
