Radio Cosmology Lab
The Low frequency Cosmology Lab is developing the high redshift 21cm line as a new observable tool to probe the early universe. We also lead or support space missions like DORA, SPARCS, and Phoenix. Though these days this work is moving more to the Interplanetary Lab.
Interplanetary Lab
I am the founding director of the ASU Interplanetary Lab, a center for small mission development and testing at ASU. For more see my Space Projects page.

Projects
HERA

The Hydrogen Epoch of Reionization Array (HERA) aims to probe the cosmic dawn to learn about fundamental physics and the first galaxies. ASU team members include:
- Danny Jacobs – Project Scientist
- Lindsay Berkhout – Digital and analog instrumentation
- Steven Murray – Theory and Pipeline Validation,
- Matt Kolopanis – Operations software and data analysis.
SPARCS

The Star Planet Activity Research Cubesat (SPARCS) will monitor stellar flares to understand their impact on exoplanets. Group team members include
- Danny Jacobs – Spacecraft and Software Integration
- Judd Bowman – Software and Payload Computer
- Tahina Tamiaramanantsoa – Flight and ground astronomy pipeline
- Matt Kolopanis – Flight and Ground Software
- Christopher McCormick (EE)
- Chandler Hutchens (Aerospace)
R&D

We are developing new technologies to be used in future space and ground-based experiments. Areas of focus include:
- cubesat capability (Phoenix, DORA, SPARCS)
- high data rate interconnect (DORA)
- precision radiometry (ECHO, EDGES)
- Advanced signal processing (EPIC)
- Ravi Shankar (MS EE)
- Arib Islam (EE)
- Chandler Hutchens (Aero)
- Karthik Reddy (LoCo Postdoc)
