Momen Diab completed his Ph.D. in astrophotonics at the Leibniz Institute for Astrophysics (AIP) and the University of Potsdam. His recent research involved studying photonic lanterns and adaptive optics as enabling technologies for integrated IR astronomical instruments. He also worked on modeling atmospheric turbulence and waveguides.
Previously, he was part of projects in photonic wavefront sensing and ground-to-satellite laser links.
I use weak gravitational lensing and other precision cosmology methods to measure the large-scale structure of the universe. Much of my work involves developing statistical techniques that distill cosmological information from measurements of galaxy sizes, shapes, and colors. As a member of the science team for the upcoming Roman Space Telescope, I also work on planning, analysis, and pipeline development for the next generation of cosmology surveys.
My research focuses on reconstructing the formation conditions of the Milky Way using the positions, kinematics, ages, and chemical compositions of pulsating variable stars. I use data from proprietary surveys and publicly available databases, including (but not limited to) the Halo Outskirts With VAriable STars (HOWVAST), the Southern Stellar Stream Spectroscopic Survey (S⁵), and the Gaia mission. These projects are pivotal to lay the groundwork for exploiting the large amount of data upcoming in the next generation of large sky surveys.
As a member in the SDSS-V collaboration, I work mainly on developing and running the spectral analysis pipelines for the Milky Way Mapper (MWM). My research focuses on analysing the chemo-dynamical properties of star clusters and stellar populations in the Milky Way and nearby dwarf galaxies. I also developed a real-time extraction GUI software for a new IFU instrument (IFU-M) designed for use on the Magellan/Clay telescope.
