Caryl Gronwall

Caryl Gronwall is a Research Professor in the Department of Astronomy and Astrophysics at Pennsylvania State University. Her research focuses on high-energy astrophysical phenomena, galaxy evolution, and large-scale structure formation at cosmic noon. She utilizes multiwavelength observations from facilities like the Swift satellite, HETDEX, and the ODIN survey to study gamma-ray bursts (GRBs), Lyman Alpha Emitters (LAEs), and protoclusters.

Key projects include analyzing GRB afterglows for transient characterization, investigating the intergalactic medium via Lyman Alpha absorption, and mapping galaxy clustering in high-redshift environments. Her work with LIGO/Virgo collaborations explores gravitational wave events through Swift/XRT follow-up observations.

Research interests span cosmological structure formation, UV background measurements, and the evolution of star-forming galaxies. She contributes to surveys like UVCANDELS and the HETDEX Public Source Catalog, advancing understanding of galaxy populations and quenching mechanisms in protoclusters.

Her recent studies highlight strong clustering of LAEs in ODIN fields, metallicity variations in Seyfert galaxies, and dust attenuation effects in nearby star-forming regions. Collaborative efforts with international teams address questions about cosmic reionization and the IRX-β relation in galactic regions.
