Approximate Bayesian Neural Doppler Imaging
A. Asensio Ramos, C. Diaz Baso, O. Kochukhov
The non-uniform surface temperature distribution of rotating active stars is routinely mapped with the Doppler Imaging technique. Inhomogeneities in the surface produce features in…
Learning to do multiframe wavefront sensing unsupervisedly: applications to blind deconvolution
A. Asensio Ramos, N. Olspert
Observations from ground based telescopes are affected by the presence of the Earth atmosphere, which severely perturbs them. The use of adaptive optics techniques has allowed us t…
MOLPOP-CEP: An Exact, Fast Code for Multi-Level Systems
A. Asensio Ramos, M. Elitzur
We present MOLPOP-CEP, a universal line transfer code that allows the exact calculation of multi-level line emission from a slab with variable physical conditions for any arbitrary…
Random sub-Nyquist polarimetric modulator
A. Asensio Ramos
We show that it is possible to measure polarization with a polarimeter that gets rid of the seeing while still measuring at a frequency well below that of the seeing. We study a st…
Compressive Sensing for Spectroscopy and Polarimetry
A. Asensio Ramos, A. Lopez Ariste
We demonstrate through numerical simulations with real data the feasibility of using compressive sensing techniques for the acquisition of spectro-polarimetric data. This allows us…
