Oscar Macias is an astrophysicist and Assistant Professor of Physics at San Francisco State University. His work focuses on high-energy astrophysics, indirect dark matter detection, and the application of artificial intelligence in astrophysics. Macias is known for his contributions to modeling gamma-ray emissions and for significant research on the Galactic Center gamma-ray excess.
Early life and education
Oscar Macias was born in El Peñol, Colombia. He earned a Bachelor of Science in Civil Engineering and a Master of Science in Physics from the National University of Colombia. He later completed his Ph.D. in Physics at the University of Canterbury in 2014, focusing on gamma-ray astronomy and indirect dark matter detection.
Career
Macias has held several academic and research positions:
- Assistant Professor, San Francisco State University, United States (2023–present)
- GRAPPA Prize Fellow, University of Amsterdam, The Netherlands (2021–2023)
- Postdoctoral Researcher, Kavli Institute for the Physics and Mathematics of the Universe, University of Tokyo, Japan (2018–2021)
- Postdoctoral Research Associate, Virginia Tech, United States (2015–2018)
Research and contributions
Macias's research spans indirect dark matter detection, high-energy astrophysics, and artificial intelligence in astrophysics. Key achievements include:
- Proposing one of the leading theories[1] for the largest gamma-ray substructure in the Fermi Bubbles.[2]
- Publishing a 2013 paper[3] that triggered significant research into the Fermi GeV Excess.
