FB-GDM: Fully-Bayesian Guided Diffusion Models for High-Dimensional Linear Inverse Problems via Unsupervised Variational Inference
Gatien Séguy, Thomas Rodet
Diffusion models are powerful priors for linear inverse problems, but the reference guidance methods, Diffusion Posterior Sampling (DPS) and Pseudoinverse-Guided Diffusion Models (…
Estimating hyperparameters and instrument parameters in regularized inversion. Illustration for SPIRE/Herschel map making
F. Orieux, J. -F. Giovannelli, T. Rodet +1
We describe regularized methods for image reconstruction and focus on the question of hyperparameter and instrument parameter estimation, i.e. unsupervised and myopic problems. We…
Super-resolution in map-making based on a physical instrument model and regularized inversion. Application to SPIRE/Herschel
F. Orieux, J. -F. Giovannelli, T. Rodet +3
We investigate super-resolution methods for image reconstruction from data provided by a family of scanning instruments like the Herschel observatory. To do this, we constructed a…
Optical performance of the JWST MIRI flight model: characterization of the point spread function at high-resolution
P. Guillard, T. Rodet, S. Ronayette +16
The Mid Infra Red Instrument (MIRI) is one of the four instruments onboard the James Webb Space Telescope (JWST), providing imaging, coronagraphy and spectroscopy over the 5-28 mic…
Physical properties of the Sh2-104 HII region as seen by Herschel
J. A. Rodón, A. Zavagno, J. -P. Baluteau +46
Context: Sh2-104 is a Galactic H ii region with a bubble morphology, detected at optical and radio wavelengths. It is considered the first observational confirmation of the collect…
Herschel-SPIRE spectroscopy of the DR21 molecular cloud core
Glenn J. White, A. Abergel, L. Spencer +47
We present far-infrared spectra and maps of the DR21 molecular cloud core between 196 and 671 microns, using the Herschel-SPIRE spectrometer. Nineteen molecular lines originating f…
