Mapping the invisible: Gravity as a Lens to Reveal Dark Matter
Dark Matter is invisible, and mapping it is often a slow and subjective process. But with the right method, mapping it can be faster, consistent, and ready for more clusters.
About 85% of the universe is made of Dark Matter, and this matter cannot be seen.
However, its gravity leaves its traces, as it bends and distorts the shapes of the background galaxies.
By measuring these distortions, we can map Dark Matter. But choosing which background galaxies to measure these distortions on is not an easy task. It is often done slowly and subjectively. My summer research aimed to change that.
This poster is a summary of what I have done this summer at LASTRO, and it shows the map of Dark Matter that was achieved using the background galaxies selected using my method.
My research report detailing this process will also be uploaded soon!
