Report

Bayesian reconstruction of sparse raster-scanned mid-infrared optoacoustic signals enables fast, label-free chemical microscopy

Autor: Berger, Constantin, Kim, Myeongseop, Scheel-Platz, Lukas, Ntziachristos, Vasilis, Jüstel, Dominik, Pleitez, Miguel A.

Hyperspectral optoacoustic microscopy (OAM) enables obtaining images with label-free biomolecular contrast, offering excellent perspectives as a diagnostic tool to assess freshly excised and unprocessed tissues. However, time-consuming raster-scannin

A Method for Accurate Spatial Focusing Simulation via Numerical Integration and its Application in Optoacoustic Tomography

Autor: Bader, Maximilian, Haim, Philipp, Scheel-Platz, Lukas Imanuel, Karlas, Angelos, Irl, Hedwig, Ntziachristos, Vasilis, Jüstel, Dominik

The spatial sensitivity of an ultrasound transducer, which strongly influences its suitability for different applications, depends on the shape of the transducer surface. Accurate simulation of these spatial effects is important for transducer charac

Re-Envisioning Numerical Information Field Theory (NIFTy.re): A Library for Gaussian Processes and Variational Inference

Autor: Edenhofer, Gordian, Frank, Philipp, Roth, Jakob, Leike, Reimar H., Guerdi, Massin, Scheel-Platz, Lukas I., Guardiani, Matteo, Eberle, Vincent, Westerkamp, Margret, Enßlin, Torsten A.

Publikováno v: Journal of Open Source Software, volume 9(98), year 2024, page 6593

Imaging is the process of transforming noisy, incomplete data into a space that humans can interpret. NIFTy is a Bayesian framework for imaging and has already successfully been applied to many fields in astrophysics. Previous design decisions held t

First spatio-spectral Bayesian imaging of SN1006 in X-ray

Autor: Westerkamp, Margret, Eberle, Vincent, Guardiani, Matteo, Frank, Philipp, Platz, Lukas, Arras, Philipp, Knollmüller, Jakob, Stadler, Julia, Enßlin, Torsten

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 X-ray observations. In particular, the supernova remnant SN1006 is of

Report

Multi-Component Imaging of the Fermi Gamma-ray Sky in the Spatio-spectral Domain

Autor: Platz, Lukas I., Knollmüller, Jakob, Arras, Philipp, Frank, Philipp, Reinecke, Martin, Jüstel, Dominik, Enßlin, Torsten A.

Publikováno v: A&A 680, A2 (2023)

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 brightness to be composed of a diffuse-emission and a point-source compone
