Interpreting map-based / spectral properties of CMB foregrounds
Gilles Weymann-Despres, Léo Vacher, Michael E. Jones +5
Map-space / decompositions of linear polarization are attractive for foreground and CMB analyses because they separate parity families: -family patterns directly contamina…
: A Differentiable and GPU-accelerated Synchrotron Simulation Package
Kangning Diao, Zack Li, Richard D. P. Grumitt +1
We introduce synax, a novel library for automatically differentiable simulation of Galactic synchrotron emission. Built on the JAX framework, synax leverages JAX's capabilities, in…
Modeling Foreground Spatial Variations in 21 cm Gaussian Process Component Separation
Kangning Diao, Richard D. P. Grumitt, Yi Mao
Gaussian processes (GPs) have been extensively utilized as nonparametric models for component separation in 21 cm data analyses. This exploits the distinct spectral behavior of the…
Sequential Kalman Tuning of the -preconditioned Crank-Nicolson algorithm: efficient, adaptive and gradient-free inference for Bayesian inverse problems
Richard D. P. Grumitt, Minas Karamanis, Uroš Seljak
Ensemble Kalman Inversion (EKI) has been proposed as an efficient method for the approximate solution of Bayesian inverse problems with expensive forward models. However, when appl…
Flow Annealed Kalman Inversion for Gradient-Free Inference in Bayesian Inverse Problems
Richard D. P. Grumitt, Minas Karamanis, Uroš Seljak
For many scientific inverse problems we are required to evaluate an expensive forward model. Moreover, the model is often given in such a form that it is unrealistic to access its…
The C-Band All-Sky Survey (C-BASS): New Constraints on the Integrated Radio Spectrum of M 31
Stuart E. Harper, Adam Barr, C. Dickinson +11
The Andromeda galaxy (M31) is our closest neighbouring spiral galaxy, making it an ideal target for studying the physics of the interstellar medium in a galaxy very similar to our…
