Substructure Detection Reanalyzed: Dark Perturber shown to be a Line-of-Sight Halo
Atınç Çağan Şengül, Cora Dvorkin, Bryan Ostdiek +1
Observations of structure at sub-galactic scales are crucial for probing the properties of dark matter, which is the dominant source of gravity in the universe. It will become incr…
Image segmentation for analyzing galaxy-galaxy strong lensing systems
Bryan Ostdiek, Ana Diaz Rivero, Cora Dvorkin
The goal of this paper is to develop a machine learning model to analyze the main gravitational lens and detect dark substructure (subhalos) within simulated images of strongly len…
Extracting the Subhalo Mass Function from Strong Lens Images with Image Segmentation
Bryan Ostdiek, Ana Diaz Rivero, Cora Dvorkin
Detecting substructure within strongly lensed images is a promising route to shed light on the nature of dark matter. However, it is a challenging task, which traditionally require…
