Clusters and weak lensing

24. Strong lensing by cluster galaxies

Massimo Meneghetti (INAF)

1. Strong lens modelling of galaxy clusters with JWST data

Gregor Rihtaršič (University of Ljubljana)

11/14/24, 9:50 AM

Contributed talk

The James Webb Space Telescope is revolutionizing the field of strong gravitational lensing in galaxy clusters, allowing us to go further and fainter in our search for multiply imaged galaxies. I will present the recent results of the Canadian NIRISS Unbiased Cluster Survey (CANUCS), targeting 5 massive clusters with 3 instruments onboard JWST. With the example of MACS 0416 - the cluster with...

11. Weak lensing mass calibration of clusters (SPTxDES data)

Asmaa Mazoun (Technische Universität München (TUM))

11/14/24, 10:10 AM

Contributed talk

In this talk, I will discuss how gravitational weak lensing data can be leveraged to calibrate the masses of galaxy clusters. The South Pole Telescope (SPT) survey detects clusters via the thermal Sunyaev-Zel'dovich (SZ) effect, but this method does not yield direct mass measurements. Gravitational weak lensing provides a complementary approach, enabling accurate mass estimations that are...
