The road toward imaging a black hole: A personal perspective
Natural Sciences, Volume 2, Issue 4, October 2022., 2022 The article describes the authors personal journey towards developig the Event Horizon Telescope and the first image of a black hole. Left: predcition made by the author and collaborators proposing the black hole imaging in 2000. Right: the two images observed and published by the Event Horizon Telescope in 2019 and 2022.

A Distributed Storage for Astroparticle Physics [PDF]
EPJ Web of Conferences, 2019 In this paper we present the architecture of a distributed data storage for astroparticle physics. The main advantage of the proposed architecture is the possibility to extract data on both file and event level for further processing and analysis.

Single‐exposure X‐ray phase imaging microscopy with a grating interferometer
Journal of Synchrotron Radiation, Volume 29, Issue 3, Page 794-806, May 2022., 2022 This work presents and extends the single‐exposure phase imaging capabilities of X‐ray grating interferometry as demonstrated by an implementation at beamline I13‐1 of the Diamond Light Source. The results are especially relevant for future single‐pulse imaging experiments at X‐ray free‐electron lasers.The advent of hard X‐ray free‐electron lasers ...

ChemBioChem, Volume 23, Issue 7, April 5, 2022., 2022 A novel benzaldehyde lyase for the production of chiral α‐hydroxy ketones was identified by a machine learning model and two variants with altered substrate scopes were created by rational design. All three variants exhibit significantly higher thermostability compared to the only previously described benzaldehyde lyase.

The Relationship of Lightning Radio Pulse Amplitudes and Source Altitudes as Observed by LOFAR
Earth and Space Science, Volume 9, Issue 4, April 2022., 2022 Abstract When a lightning flash is propagating in the atmosphere it is known that especially the negative leaders emit a large number of very high frequency (VHF) radio pulses. It is thought that this is due to streamer activity at the tip of the growing negative leader.

Timing Calibration and Windowing Technique Comparison for Lightning Mapping Arrays
Earth and Space Science, Volume 8, Issue 7, July 2021., 2021 Abstract Since their introduction 22 years ago, lightning mapping arrays (LMA) have played a central role in the investigation of lightning physics. Even in recent years with the proliferation of digital interferometers and the introduction of the LOw Frequency ARray (LOFAR) radio telescope, LMAs still play an important role in lightning science.
