PublicaciónExploring the correlation between dark matter, intracluster light, and globular cluster distribution in SMACS0723
We present a free-form model of SMACS0723, the first cluster observed with JWST. This model does not make any strong assumptions on the distribution of mass...

PublicaciónFast Multipole Method for Gravitational Lensing: Application to High-magnification Quasar Microlensing
We introduce the use of the fast multipole method (FMM) to speed up gravitational lensing ray tracing calculations. The method allows very fast calculation of...
