Bayesian bulge-disc decomposition of galaxy images
We introduce PHI, a fully Bayesian Markov chain Monte Carlo algorithm designed for the structural decomposition of galaxy images. PHI uses a triple layer...
Bayesian cosmic density field inference from redshift space dark matter maps
We present a self-consistent Bayesian formalism to sample the primordial density fields compatible with a set of dark matter density tracers after a cosmic...
Bayesian distances and extinctions for giants observed by Kepler and APOGEE
We present a first determination of distances and extinctions for individual stars in the first release of the APOKASC catalogue, built from the joint efforts...
Bayesian inference methodology to characterize the dust emissivity at far-infrared and submillimeter frequencies
We present a Bayesian inference method to characterize the dust emission properties using the well-known dust-${\rm H\,{\small I}}$ correlation in the diffuse...
Bent by baryons: the low-mass galaxy-halo relation
The relation between galaxies and dark matter haloes is of vital importance for evaluating theoretical predictions of structure formation and galaxy formation...
Beyond the 3rd moment: a practical study of using lensing convergence CDFs for cosmology with DES Y3
Widefield surveys probe clustered scalar fields - such as galaxy counts, lensing potential, etc. - which are sensitive to different cosmological and...
Beyond the hubble sequence - exploring galaxy morphology with unsupervised machine learning
We explore unsupervised machine learning for galaxy morphology analyses using a combination of feature extraction with a vector-quantized variational...
BG Tri: an example of a low-inclination RW Sex-type nova-like
We analyse a wealth of optical spectroscopic and photometric observations of the bright (V = 11.9) cataclysmic variable BG Tri. The Gaia DR2 parallax gives a...
Binarity and multiperiodicity in high-amplitude δ Scuti stars
We have carried out a photometric and spectroscopic survey of bright high-amplitude δ Scuti (HADS) stars. The aim was to detect binarity and multiperiodicity...
