We present , a general-purpose Bayesian analysis code aimed at models with complex internal interdependencies. Without the need for specific code by the user, interdependencies between different stages of a model pipeline are exploited for sampling efficiency: intermediate results are automatically cached, and parameters are grouped in blocks according to their dependencies and optimally sorted, taking into account their individual computational costs, so as to minimize the cost of their… Expand
Accelerating MCMC algorithms through Bayesian Deep Networks
This paper shows an alternative way of performing adaptive MCMC, by using the outcome of Bayesian Neural Networks as the initial proposal for the Markov Chain, which increases the acceptance rate in the Metropolis-Hasting algorithm and accelerate the convergence of the MCMC while reaching the same final accuracy.

Non-Gaussianity in D3-brane inflation
We update predictions for observables in the ‘delicate’ D3/D3 inflationary model on the conifold. We use a full CMB likelihood calculation to assess goodness-of-fit, which is necessary because inExpand
Inference of the optical depth to reionization from low multipole temperature and polarization Planck data
This paper explores methods for constructing low multipole temperature and polarization likelihoods from maps of the cosmic microwave background anisotropies that have complex noise properties andExpand
A new analysis of the BOSS survey, including full-shape information and post-reconstruction BAO
We present a new method for consistent, joint analysis of the preand post-reconstruction two-point functions of the BOSS survey. The post-reconstruction correlation function is used to accuratelyExpand
What it takes to measure reionization with fast radio bursts
Fast radio bursts (FRBs) are extra-galactic radio transients which, owing to the observed dispersion of the signal, can be used as cosmological probes. In this Letter we use high redshift FRBs toExpand
Strongly lensed supernovae as a self-sufficient probe of the distance duality relation
The observation of strongly lensed Type Ia supernovae enables both the luminosity and angular diameter distance to a source to be measured simultaneously using a single observation. This feature canExpand
The Parameter-Level Performance of Covariance Matrix Conditioning in Cosmic Microwave Background Data Analyses
Empirical estimates of the band power covariance matrix are commonly used in cosmic microwave background (CMB) power spectrum analyses. While this approach easily captures correlations in the data,Expand
Dark energy with oscillatory tracking potential: Observational Constraints and Perturbative effects
The cosmological models exhibiting tracker properties have great significance in the context of dark energy as they can reach the present value of dark energy density from a wide range of initialExpand
A Python compressed low-$\ell$ Planck likelihood for temperature and polarization
We present Planck-low-py, a binned low-` temperature and E-mode polarization likelihood, as an option to facilitate ease of use of the Planck 2018 large-scale data in joint-probe analysis andExpand
Small-scale Clumping at Recombination and the Hubble Tension
Despite the success of the standard ΛCDM model of cosmology, recent data improvements have made tensions emerge between lowand high-redshift observables, most importantly in determinations of theExpand


GetDist: a Python package for analysing Monte Carlo samples
Methods used the Python GetDist package to calculate marginalized one and two dimensional densities using Kernel Density Estimation (KDE) to calculate convergence diagnostics and produces tables of limits and output in latex. Expand
MontePython 3: Boosted MCMC sampler and other features
MontePython is a parameter inference package for cosmology. We present the latest development of the code over the past couple of years. We explain, in particular, two new ingredients bothExpand
Conservative constraints on early cosmology with MONTE PYTHON
Models for the latest stages of the cosmological evolution rely on a less solid theoretical and observational ground than the description of earlier stages like BBN and recombination. As suggested inExpand
Inference from Iterative Simulation Using Multiple Sequences
The Gibbs sampler, the algorithm of Metropolis and similar iterative simulation methods are potentially very helpful for summarizing multivariate distributions. Used naively, however, iterativeExpand
Nested sampling for general Bayesian computation
Nested sampling estimates directly how the likelihood function relates to prior mass. The evidence (alternatively the marginal likelihood, marginal den- sity of the data, or the prior predictive) isExpand
Monte Carlo Sampling Methods Using Markov Chains and Their Applications
SUMMARY A generalization of the sampling method introduced by Metropolis et al. (1953) is presented along with an exposition of the relevant theory, techniques of application and methods andExpand
Cosmological parameters from CMB and other data: A Monte Carlo approach

polychord: nested sampling for cosmology
PolyChord is a novel nested sampling algorithm tailored for high dimensional parameter spaces that utilises slice sampling at each iteration to sample within the hard likelihood constraint of nested sampling. Expand
