Abstract

The study of ionizing radiation escape in galaxies is crucial for understanding galaxy evolution and cosmic reionization. Ionizing radiation, produced by stars, affects the surrounding interstellar medium by ionizing hydrogen atoms. The escape fraction (fesc) is a key parameter that measures the proportion of ionizing photons that successfully escape, and it directly influences the ionization state of the universe. This study summarizes advancements in simulation and observational techniques, enhancing the understanding of the mechanisms behind ionizing radiation escape. High-resolution simulations (e.g., IllustrisTNG-50 and Thesan-1), have revealed complex structures in hydrogen distribution within galaxies, highlighting the impact of hydrogen ionization state, gas density, and dust content on the escape fraction. Advanced observational tools like JWST and ALMA have provided direct measurements of escape fractions from high-redshift galaxies, validating theoretical models. This research explores various physical factors that influence radiation escape, analyses the limitations of current research, and discusses future research directions in this field, emphasizing the importance of further refined simulations and more accurate observational data.
