Bio

Dr. Kartaltepe is an astrophysicist in the School of Physics and Astronomy. She is an expert in the areas of galaxy formation and evolution, galaxy morphologies, galaxy mergers and interactions, and the properties of infrared galaxies. She is a co-PI of the large collaboration COSMOS (The Cosmic Evolution Survey), which is a large area multiwavelength extragalactic survey, utilizing nearly every major ground- and space-based telescope. She is a PI of the COSMOS-Web Cycle 1 JWST program (the largest GO program) and a leading co-I for CEERS (The Cosmic Evolution Early Release Science Survey). She teaches courses across the undergraduate and graduate astrophysics curriculum and mentors undergraduate students, graduate students, and postdocs in a wide range of research projects.

    Collaboration with global team confirms, disproves distant galaxies

    RIT scientists have once again used data from the James Webb Space Telescope (JWST) as part of the Cosmic Evolution Early Release Science (CEERS) Survey to change the way we think about the universe and its distant galaxies. Jeyhan Kartaltepe and Rebecca Larson co-authored a paper confirming very bright galaxies in the early universe, while also disproving the identification of what would have been the most distant galaxy ever found.
