Analysis of the Euclid Quick Data Release 1: Trends in 2-Armed and 3-Armed Galaxies
Abstract
The Euclid Telescope observed three areas of the sky during a span of six months. The Euclid survey is more sensitive and has better resolution than earlier studies, allowing us to study spiral patterns in galaxies out to much larger distances than before. Using galaxy catalogs published in the Euclid Quick Data Release 1, we compared properties of 2-armed and 3-armed spiral galaxies. The 2-armed galaxies have larger concentrations, lower stellar masses, and lower rates of star formation, on average, than the three-armed galaxies. In dense environments, proportionally fewer low mass spiral galaxies are present. As a galaxy moves through a group or cluster, interstellar gas in the galaxy gets stripped out of the outer disk of the galaxy, causing star formation to decrease and the spiral arms to become less visible. This process is more effective in low mass galaxies, producing a deficiency of low mass spirals in high density environments.
