We determine parameters and abundances for 18 individual elements at the $\approx 0. 03$ dex level, even at low signal-to-noise ratio.

The impact of spectroscopic incompleteness in direct calibration of redshift distributions for weak lensing surveys
We do so by simulating the process of assembling a spectroscopic sample (including observer-assigned confidence flags) and highlight the impacts of spectroscopic target selection and redshift failures.

$\it{CosmoPower} \,$: emulating cosmological power spectra for accelerated Bayesian inference from next-generation surveys
For the CMB case, $\it{CosmoPower}$ is tested on a $\it{Planck}$ 2018 CMB temperature and polarisation analysis.

A Bayesian approach to linear regression in astronomy
I discuss a Bayesian hierarchical modeling of data with heteroscedastic and possibly correlated measurement errors and intrinsic scatter.

Self-supervised Anomaly Detection for Narrowband SETI
PetchMa/DeepSeti

•
The proposed approach is not meant to replace current narrowband searches but to demonstrate the potential to generalize to other signal types.

Wotan: Comprehensive time-series de-trending in Python
The detection of transiting exoplanets in time-series photometry requires the removal or modeling of instrumental and stellar noise.
