DenseLens -- Using DenseNet ensembles and information criteria for finding and rank-ordering strong gravitational lenses,
Bharath Chowdhary Nagam, Léon V. E. Koopmans, Edwin A. Valentijn +5
Convolutional neural networks (CNNs) are the state-of-the-art technique for identifying strong gravitational lenses. Although they are highly successful in recovering genuine lens…
Multi-band analysis of strong gravitationally lensed post-blue nugget candidates from the Kilo-Degree Survey
Rui Li, Nicola R. Napolitano, Linghua Xie +7
During the early stages of galaxy evolution, a significant fraction of galaxies undergo a transitional phase between the ``blue nugget" systems, which arise from the compaction of…
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…
