SURF: Announcements of Opportunity
Below are Announcements of Opportunity posted by Caltech faculty and JPL technical staff for the SURF program.
Each AO indicates whether or not it is open to non-Caltech students. If an AO is NOT open to non-Caltech students, please DO NOT contact the mentor.
Announcements of Opportunity are posted as they are received. Please check back regularly for new AO submissions! Remember: This is just one way that you can go about identifying a suitable project and/or mentor. Click here for more tips on finding a mentor.
Announcements for external summer programs are listed here.
New for 2021: Students applying for JPL projects should complete a SURF@JPL application instead of a "regular" SURF application.
Students pursuing opportunities at JPL must be
U.S. citizens or U.S. permanent residents.

| Project: | The First Galaxies and the First Light. | ||||||||
| Disciplines: | Astronomy/Astrophysics, Computer Science | ||||||||
| Mentor: | Tzu-Ching Chang, (JPL), tzu-ching.chang@jpl.nasa.gov | ||||||||
| Background: |
Galaxies have been studied for a long time to understand their own formation, evolution, as well as their impact in the evolution of our whole Universe. However, all these studies can mostly detect the brightest individual objects and have missed a large number of fainter galaxies that are important for many cosmic processes. Nowadays, a new technique named Intensity Mapping (IM) is under development to explore from the faintest to the brightest galaxies via the observation of large areas of the sky and compiling all the luminosity in them. This will allow us to know when the first galaxies appeared, how the light managed to escape from their centers and travel the vast space until reaching our telescopes, and how these galaxies have been evolving until the present day. JPL is a pioneer center in this new technique and is involved in the theoretical but also instrumental part, with several experiments on the ground and space. |

| Description: |
The project will include numerical modeling and/or theoretical formulations to identify potential probes useful for intensity mapping experiments. For instance, we study how combining radiation at different frequencies can reveal different processes happening in these galaxies and the large scales, and we investigate other physical processes that can be applied to this study. We have a set of numerical simulations that we want to run and use to explore how the radiation travels through the gas, giving an idea of what are the processes that we observe when analyzing the data. |
