Optical reconstruction of dust in the region of SNR RX J1713.7-3946 from astrometric data
Reimar Leike, Silvia Celli, Alberto Krone-Martins +5
The origin of the radiation observed in the region of the supernova remnant RX J1713.7-3946, one of the brightest TeV emitters, has been debated since its discovery. The existence…
Towards Bayesian Data Compression
Johannes Harth-Kitzerow, Reimar Leike, Philipp Arras +1
In order to handle large data sets omnipresent in modern science, efficient compression algorithms are necessary. Here, a Bayesian data compression (BDC) algorithm that adapts to t…
Bayesian decomposition of the Galactic multi-frequency sky using probabilistic autoencoders
Sara Milosevic, Philipp Frank, Reimar H. Leike +2
All-sky observations of the Milky Way show both Galactic and non-Galactic diffuse emission, for example from interstellar matter or the cosmic microwave background (CMB). The diffe…
Spatially Resolved Ultraviolet Spectroscopy of the Great Dimming of Betelgeuse
Andrea K. Dupree, Klaus G. Strassmeier, Lynn D. Matthews +9
The bright supergiant, Betelgeuse (Alpha Orionis, HD 39801) experienced a visual dimming during 2019 December and the first quarter of 2020 reaching an historic minimum 2020 Februa…
Comparison of classical and Bayesian imaging in radio interferometry
Philipp Arras, Hertzog L. Bester, Richard A. Perley +4
CLEAN, the commonly employed imaging algorithm in radio interferometry, suffers from a number of shortcomings: in its basic version it does not have the concept of diffuse flux, an…
Resolving nearby dust clouds
R. H. Leike, M. Glatzle, T. A. Enßlin
Aims: Mapping the interstellar medium in 3D provides a wealth of insights into its inner working. The Milky Way is the only galaxy for which detailed 3D mapping can be achieved in…
