The Massively Accreting Cluster A2029

Understand

We explore the structure of galaxy cluster Abell 2029 and its surroundings based on intensive spectroscopy along with X-ray and weak lensing observations.

• The redshift survey includes 4376 galaxies (1215 spectroscopic cluster members) within 40 arcmin of the cluster center; the redshifts are included here.
• Two subsystems, A2033 and a Southern Infalling Group (SIG) appear in the infall region based on the spectroscopy as well as on the weak lensing and X-ray maps.
• The complete redshift survey of A2029 also identifies at least 12 foreground and background systems (10 are extended X-ray sources) in the A2029 field; we include a census of their properties.
