Cold giant discoveries from a joint radial-velocity and astrometry framework
Pablo A. Peña, James S. Jenkins, Fabo Feng +11
The population of long-period giant planets shapes planetary system architectures and formation pathways, but these cold Jupiters remain relatively unexplored. Radial velocity (RV)…

EMPEROR I. Exoplanet MCMC parallel tempering for RV orbit retrieval
Pablo A. Peña, James S. Jenkins
We present EMPEROR, an open-source Python framework designed for efficient exoplanet detection and characterisation with radial velocities (RV). EMPEROR integrates Dynamic Nested S…

Closing the Evidence Gap: reddemcee, a Fast Adaptive Parallel Tempering Sampler
Pablo A. Peña, James S. Jenkins
Markov Chain Monte Carlo (MCMC) excels at sampling complex posteriors but traditionally lags behind nested sampling in accurate evidence estimation, which is crucial for model comp…
