Jasleen Kaur Matharu

Jasleen Kaur Matharu is a Postdoctoral Researcher at the Cosmic Dawn Center (DAWN), which is part of the Niels Bohr Institute at the University of Copenhagen. She is actively contributing to cutting-edge research on galaxy formation and evolution during the Cosmic Dawn period using data from the James Webb Space Telescope.

Dr. Matharu's research focuses on observational cosmology, particularly studying high-redshift galaxies (z > 4) to understand galaxy formation in the early universe. Her work encompasses galaxy morphology evolution, spatially resolved star formation, UV luminosity functions, and the physical properties of galaxies during the first 1-2 billion years after the Big Bang. She is a key contributor to major JWST projects including CANUCS, FRESCO, and the DAWN JWST Archive.

Her publication record shows consistent output in top astronomy journals, with multiple papers published in 2024-2025 that have already garnered significant citations. Her research leverages advanced data analysis techniques on JWST observations to probe the physical processes driving galaxy evolution in the early universe.

As a researcher at the Cosmic Dawn Center, Dr. Matharu collaborates with an international team of astronomers working at the forefront of observational cosmology. The center provides a vibrant research environment focused on understanding the formation of the first stars, galaxies, and black holes.

Her work involves extensive analysis of multi-wavelength JWST data, particularly using NIRCam imaging and grism spectroscopy to study galaxy properties across cosmic time. This research is crucial for testing theoretical models of galaxy formation and understanding how the universe evolved from its early stages to its current state.
