A Collection of German Science Interests in the Next Generation Very Large Array
M. Kadler, D. A. Riechers, J. Agarwal +88
The Next Generation Very Large Array (ngVLA) is a planned radio interferometer providing unprecedented sensitivity at wavelengths between 21 cm and 3 mm. Its 263 antenna element ar…
Angular complexity in strong lens substructure detection
Conor M. O'Riordan, Simona Vegetti
Strong gravitational lensing can be used to find otherwise invisible dark matter subhaloes. In such an analysis, the lens galaxy mass model is a significant source of systematic un…
Selection functions of strong lens finding neural networks
A. Herle, C. M. O'Riordan, S. Vegetti
Convolution Neural Networks trained for the task of lens finding with similar architecture and training data as is commonly found in the literature are biased classifiers. An under…
Strong gravitational lensing as a probe of dark matter
S. Vegetti, S. Birrer, G. Despali +8
Dark matter structures within strong gravitational lens galaxies and along their line of sight leave a gravitational imprint on the multiple images of lensed sources. Strong gravit…
A lensed radio jet at milli-arcsecond resolution II: Constraints on fuzzy dark matter from an extended gravitational arc
Devon M. Powell, Simona Vegetti, J. P. McKean +4
Using a single gravitational lens system observed at milli-arcsecond resolution with very long baseline interferometry (VLBI), we place a lower bound on the mass of the…
Probing sub-galactic mass structure with the power spectrum of surface-brightness anomalies in high-resolution observations of galaxy-galaxy strong gravitational lenses. I. Power-spectrum measurement and feasibility study
D. Bayer, L. V. E. Koopmans, J. P. McKean +4
While the direct detection of the dark-matter particle remains very challenging, the nature of dark matter could be possibly constrained by comparing the observed abundance and pro…
