Reconstructing Merger Timelines Using Star Cluster Age Distributions: The Case of MCG+08-11-002

Davies, Rebecca; Medling, Anne; U, Vivian; Max, Claire; Sanders, David; Kewley, Lisa

Description

We present near infrared imaging and integral field spectroscopy of the centre of the dusty luminous infrared galaxy merger MCG+08-11-002, taken using the Near InfraRed Camera 2 (NIRC2) and the OH-Suppressing InfraRed Imaging Spectrograph (OSIRIS) on Keck II. We achieve a spatial resolution of ∼25 pc in the K band, allowing us to resolve 41 star clusters in the NIRC2 images. We calculate the ages of 22/25 star clusters within the OSIRIS field using the equivalent widths of the CO 2.3μm...[Show more]
