Bayesian Image Reconstruction with Spatially Variant PSFs in X-ray Astronomy
Vincent Eberle, Matteo Guardiani, Margret Westerkamp +4
X-ray observatories introduce unwanted instrumental effects into photon count data that must be accurately accounted for. In particular, the spatially variant point spread function…
Bayesian polarization calibration and imaging in very long baseline interferometry
Jong-Seo Kim, Jakob Roth, Jongho Park +6
Extracting polarimetric information from very long baseline interferometry (VLBI) data is demanding but vital for understanding the synchrotron radiation process and the magnetic f…
Bayesian Imaging of Interferometric Data from Polarized Electromagnetic Signals
Philipp Arras, Jakob Roth, Martin Reinecke +4
We present an imaging algorithm for polarimetric interferometric data from radio telescopes. It is based on Bayesian statistics and thereby able to provide uncertainties and to inc…
Bayesian self-calibration and imaging in Very Long Baseline Interferometry
Jong-Seo Kim, Aleksei S. Nikonov, Jakob Roth +5
Self-calibration methods with the CLEAN algorithm have been widely employed in Very Long Baseline Interferometry (VLBI) data processing in order to correct antenna-based amplitude…
Resolving Horizon-Scale Dynamics of Sagittarius A*
Jakob Knollmüller, Philipp Arras, Torsten Enßlin
Sagittarius A* (Sgr A*), the supermassive black hole at the heart of our galaxy, provides unique opportunities to study black hole accretion, jet formation, and gravitational physi…
First spatio-spectral Bayesian imaging of SN1006 in X-ray
Margret Westerkamp, Vincent Eberle, Matteo Guardiani +6
Supernovae are an important source of energy in the interstellar medium. Young remnants of supernovae have a peak emission in the X-ray region, making them interesting objects for…
Multi-Component Imaging of the Fermi Gamma-ray Sky in the Spatio-spectral Domain
Lukas I. Platz, Jakob Knollmüller, Philipp Arras +4
We perform two distinct spatio-spectral reconstructions of the gamma-ray sky in the range of 0.56-316 GeV based on Fermi Large Area Telescope (LAT) data. Both describe the sky brig…
