EA: Influence of environment on the AGN-starburst connection in small galaxy systems – Duplancic
April 20, 2022 @ 12:00 pm - 12:15 pm
In this work, we study the relationship between star formation activity and the active galactic nucleus phenomenon, known as AGN-starburst connection. For this purpose, we use a catalogue of galaxy systems with a low number of members (2 to 6) and different diagnostic diagrams to identify active galaxies both in the optical and in the infrared. These methods also allow the identification of star-forming galaxies and “Retired/Passive” objects that have already completed their star formation cycle. We compare the fractions of AGN and galaxies with active star formation, seeking to study the conditions that favour this type of activity. Also, we characterize the density environment inhabited by the systems, in order to study its influence on the AGN-starburst connection at different scales.
