Looking for the impact of gravitational perturbations in Lyman-Alpha Emitting galaxy systems
Candela Cerdosino
Lyman-Alpha Emitting galaxies (LAEs) are generally young, star-forming galaxies characterized by their prominent Lyman-Alpha emission. When this emission occurs at redshifts greater than approximately 2, it shifts towards the optical window, which allows its detection by ground-based observations. In this study, we utilize the first data from the One-hundred-deg$^2$ DECam
Imaging in Narrowbands (ODIN) survey, the largest narrowband filter survey to date, which employs three narrowband filters to discover LAEs at three equally spaced periods in cosmological history. In this presentation, we show the preliminary results of using LAE systems as a proxy for host halo mass, where we investigate the relationship between halo mass and Lyman-Alpha luminosity, among other factors, in agreement with previous observations and models. The ultimate goal is to investigate whether gravitational perturbations between LAEs in multiple systems are sufficient to explain the changes in their properties.
