Article Synopsis
- - Galaxy clusters are huge structures containing thousands of galaxies and a hot intracluster medium (ICM), which makes up much of their mass and changes over time due to matter accumulation and mergers with other clusters.
- - Previous observations of the ICM have mostly focused on older clusters, leaving a gap in understanding the ICM during the formation of the first massive clusters.
- - Recent detection of the thermal Sunyaev-Zeldovich effect in the Spiderweb protocluster shows the presence of a nascent ICM about 10 billion years ago, revealing a less intense signal than expected, indicating a younger, active cluster formation phase.
We develop a process of image-plane self-calibration for interferometric imaging data. The process is based on shape-orientation-size (SOS) conservation for the principal triangle in an image generated from the three fringes made from a triad of receiving elements, in situations where interferometric phase errors can be factorized into element-based terms. The basis of the SOS conservation principle is that, for a three-element array, the only possible image corruption due to an element-based phase screen is a tilt of the aperture plane, leading to a shift in the image plane.
