ERGO-ML: Comparing IllustrisTNG and HSC galaxy images via contrastive learning Open
Modern cosmological hydrodynamical galaxy simulations provide tens of thousands of reasonably realistic synthetic galaxies across cosmic time. However, quantitatively assessing the level of realism of simulated universes in comparison to t…

ERGO-ML: Towards a robust machine learning model for inferring the fraction of accreted stars in galaxies from integral-field spectroscopic maps Open
Quantifying the contribution of mergers to the stellar mass of galaxies is key for constraining the mechanisms of galaxy assembly across cosmic time. However, the mapping between observable galaxy properties and merger histories is not tri…

Momentum predictability and heat accumulation in laser-based space debris removal (Erratum) Open
The article [Opt. Eng. 58(1), 011004 (2018), doi: https://doi.org/10.1117/1.OE.58.1
\n.011004] was originally published with two errors concerning 1) the computation of the optimum fluence for momentum coupling, and 2) simulation results o…

ERGO-ML I: Inferring the assembly histories of IllustrisTNG galaxies from integral observable properties via invertible neural networks Open
A fundamental prediction of the LambdaCDM cosmology is the hierarchical build-up of structure and therefore the successive merging of galaxies into more massive ones. As one can only observe galaxies at one specific time in cosmic history,…

Small space debris objects of even a few centimeters can cause severe damage to satellites.
\nPowerful lasers are often proposed for pushing small debris by laser-ablative recoil toward an orbit where atmospheric burn-up yields their remed…

Removal of Small-Sized Space Debris by Laser-Ablative Momentum Generation Open
Small-sized space debris objects pose a challenging threat for space security: Within a size
\nrange of 1 to 10 centimeters they are still large enough to cause severe damage to space assets
\nbut, moreover, they are almost too small to be…

Experimental verification of high energy laser-generated impulse for remote laser control of space debris Open
Walking along a beach one may notice debris being washed ashore from the vast oceans. Then, turning your head up at night you even might noticed a shooting star or a bright spot passing by. Chances are, that you witnessed space debris, end…

Numerical Simulations on Momentum Coupling and Orbit Modification in Laser-Based Debris Removal Open
One proposed method of space debris removal is the irradiation of particleswith laser pulses. If the laser energy is high enough, ablation of the surface is occurring and a recoil is formed. With the generated change in momentum and thus c…
