AI-Generated Deep Dive Summary
An international team of scientists, led by researchers from the Institute of Cosmos Sciences at the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC), has unveiled REGALADE, an unprecedented catalog containing nearly 80 million galaxies. This groundbreaking project, published in the journal *Astronomy & Astrophysics*, represents a major milestone in modern astronomy. By mapping the entire sky with unparalleled precision, REGALADE provides astronomers with a tool to study cosmic events and phenomena with levels of accuracy previously unattainable.
REGALADE's significance lies in its ability to capture an extraordinary volume of data—spanning vast regions of space and offering detailed insights into galaxy distributions, structures, and interactions. This catalog not only doubles the number of galaxies observed in previous surveys but also employs advanced computational methods to ensure high accuracy and reliability. Such a comprehensive dataset enables researchers to explore large-scale cosmic structures, study dark matter and dark energy, and analyze the distribution of galaxies over time.
The creation of REGALADE marks a turning point for astronomy by providing a foundation for future research. Its extensive coverage of the sky allows scientists to investigate rare cosmic events, such as galaxy mergers or the formation of black holes, with unprecedented detail. Additionally, this catalog serves as a valuable resource for both theoretical and observational astronomers, fostering new discoveries and advancing our understanding of the
