Using Neural Networks to Automate the Identification of Brightest Cluster Galaxies in Large Surveys

The Astrophysical Journal
Brightest cluster galaxies (BCGs) lie deep within the largest gravitationally bound structures in existence. Though some cluster finding techniques identify the position of the BCG and use it as the cluster center, other techniques may not automatically ...

Utilizing Voronoi Tessellations to Determine Radial Density Profiles

The Astronomical Journal
We have developed a novel method of determining 2D radial density profiles for astronomical systems of discrete objects using Voronoi tessellations. This Voronoi-based method was tested against the standard annulus-based method on five simulated systems ...

The z ∼ 1.03 Merging Cluster SPT-CL J0356–5337: New Strong Lensing Analysis with HST and MUSE

The Astrophysical Journal
We present a strong lensing analysis and reconstruct the mass distribution of SPT-CL J0356−5337, a galaxy cluster at redshift z = 1.034. Our model supersedes previous models by making use of new multiband Hubble Space Telescope data and Multi-Unit ...

A High-Caliber View of the Bullet Cluster through JWST Strong and Weak Lensing Analyses

The Astrophysical Journal Letters
The Bullet Cluster (1E 0657-56) is a key astrophysical laboratory for studying dark matter, galaxy cluster mergers, and shock propagation in extreme environments.
