Looking for Dark Matter in the Rotation Curves of the Hubble Tuning Fork Galaxy Diagram Department of Natural sciences: Physics Project advisor: Dr. Scott Schneider Presented by: Ceré L. Rettig

Objectives Research galaxy rotation curves for the six different types of spiral galaxies. Investigate mathematical models for ordinary matter and dark matter to generate rotation curves. Research genetic algorithms. Study Dane Falberg’s programing with genetic algorithms. Modify the software, to fit galaxy rotation. If time is available see if this process can be done with lenticular galaxies.

Where did the idea come from? P. Charbonneau, The Astrophysical Journal Supplemental Series 309, 101 (1995).

What did I add to the idea?

Lenticular Galaxy

Galaxy Rotation Curve

Genetic Algorithm

Materials and Methods Materials Methods LTU Laptop. Specifics still unknown. Stable internet connection. Mathematical Analysis. Application of genetic algorithms. External hard drive to back up data!

Sustainability This project is very sustainable since everything is being done through the use of computers including: File sharing – Google Drive Electronic Feedback – PDF annotator E-mail Facebook Utilizing genetic algorithms also limits resources since I will be doing limited calculations manually (papyrus).

Budget No set budget, most likely to be $0. Conferences

Timeline July 8 – September 8 2014 September 8 – November 8, 2014 Investigate current theories on rotation curves with ordinary and dark matter. September 8 – November 8, 2014 Modify GA programs to search for desired parameters. November 8 – January 8, 2015 Gather data sets for rotation curves.

Timeline January 8 – March 8, 2015 March 8 – May 8, 2015 Run GA programs to search for parameters to find best fit. March 8 – May 8, 2015 Ideally present project at conferences
