High-Redshift Galaxies

More about the book

High-redshift galaxies emerged as a distinct research field in the late 20th century, particularly with the advent of the Lyman-break technique, which enabled the identification of significant samples of these objects. The introduction of 8 to 10-m telescopes provided the first reliable spectroscopic data. Today, high-redshift galaxies represent a crucial area of astrophysics, contributing to 5–10% of publications in major astronomy journals. However, the rapid development of this field and the constant influx of new results pose challenges for compiling comprehensive resources. Despite these challenges, the extensive body of existing literature and the growing interest in high-redshift galaxies justify the need for a summarization and evaluation of the available data. This is particularly timely as we reach the end of the first decade of the 21st century, a period during which the current generation of ground-based optical telescopes, the Hubble Space Telescope, and major radio telescopes have been operational for one to two decades. While these instruments will continue to yield significant scientific findings, many initial programs utilizing their unique capabilities have concluded, making it an opportune moment to reflect on their contributions to the field.
