State-space representation of Matérn and Damped Simple Harmonic Oscillator Gaussian processes
Andrés Jordán, Susana Eyheramendy, Johannes Buchner
Gaussian processes (GPs) are used widely in the analysis of astronomical time series. GPs with rational spectral densities have state-space representations which allow O(n) evaluat…
Dalek -- a deep-learning emulator for TARDIS
Wolfgang E. Kerzendorf, Christian Vogl, Johannes Buchner +3
Supernova spectral time series contain a wealth of information about the progenitor and explosion process of these energetic events. The modeling of these data requires the explora…
XZ: Deriving redshifts from X-ray spectra of obscured AGN
Charlotte Simmonds, Johannes Buchner, Mara Salvato +2
Context: Redshifts are fundamental for our understanding of extragalactic X-ray sources. Ambiguous counterpart associations, expensive optical spectroscopy and/or multimission mult…
