Milky Way Atlas: A radial-velocity-resolved, three-dimensional map of H I within 1.25 kpc

Lewis McCallum, Laurin Söding, Mareike Berkner +9

We present a velocity-resolved three-dimensional map of local atomic hydrogen (HI) within 1.25 kpc of the Sun, tackling the challenge of converting emission from position-position-…

Nonparametric Variational Inference Reconstruction of the Cosmic Expansion History from SNe Ia -- the charm2 code

Iason Saganas, Matteo Guardiani, Natalia Porqueres +1

Cosmological analyses using the latest set of type Ia SNe data weakly favor an evolving dark energy (EDE) model without strongly disfavoring the standard LCDM paradigm. Nonparametr…

The Universal Bayesian Imaging Kit

Torsten Enßlin, Vincent Eberle, Matteo Guardiani +1

Bayesian imaging of astrophysical measurement data shares universal properties across the electromagnetic spectrum: it requires probabilistic descriptions of possible images and sp…

Bayesian Multi-wavelength Imaging of the LMC SN1987A with SRG/eROSITA

Vincent Eberle, Matteo Guardiani, Margret Westerkamp +4

The eROSITA Early Data Release (EDR) and eROSITA All-Sky Survey (eRASS1) data have already revealed a remarkable number of undiscovered X-ray sources. Using Bayesian inference and…

Latent-space Field Tension for Astrophysical Component Detection An application to X-ray imaging

Matteo Guardiani, Vincent Eberle, Margret Westerkamp +3

Modern observatories are designed to deliver increasingly detailed views of astrophysical signals. To fully realize the potential of these observations, principled data-analysis me…
