Welcome to Jahmour’s homepage

I am a PhD candidate in the Department of Physics and a member of the Center for Cosmology and AstroParticle Physics (CCAPP) at The Ohio State University. My advisor is Prof. Chris Hirata. Prior to the COVID-19 pandemic, I could be frequently found attending CCAPP events such as Astro Coffee, Cosmology Lunch, and the CCAPP Seminar in-person. Now you can find me in attendance virtually over Zoom.

My primary research questions are: a) What is dark energy? b) How can we make higher-precision measurements of cosmological parameters?

As a theoretical cosmologist, I approach these problems by constructing improved frameworks to extract cosmological information. I do this through a combination of analytical work, simulations, and comparisons to real data. In each of my past projects, I made these frameworks publicly available for use by the broader precision cosmology community. For one of those, I helped implement the framework directly into the weak lensing pipeline for the Nancy Grace Roman Space Telescope (formerly WFIRST). A similar plan is underway for implementing my improved Lyman-alpha forest biasing model into the Dark Energy Spectroscopic Instrument (DESI) Lyman-alpha pipeline.

I am a member of the American Physical Society (APS), the National Society of Black Physicists (NSBP), and the Society for the Advancement of Chicanos and Native Americans in Science (SACNAS).

I am also a member of two collaborations: I sit on the detector working group for the Roman Space Telescope and I am part of the Lyman-alpha working group for DESI. In May 2020 I became a founding member of the DESI Weekly Research Forum organizing committee.
