Manual 4D annotations of Micro X-ray CT time-series (4D dataset)
<p>The 4D (3D+time) manual annotations of https://doi.org/10.5281/zenodo.4293394. For the annotation the SuRVoS workbench was used (https://doi.org/10.5281/10.5281/zenodo.247547) and our proposed hidden Markov model (HMM-T, https://doi.org/10.5281/zenodo.4416013 ) designed to refine 4D semantic segmentations made by a 3D semantic segmentation CNN after its applied on 4D data. Only slices 740-742 and 747-749 (refining to the first axis) are partially annotated. We acknowledge Diamond Light Source for the time on I13-2 under proposal mt9396.</p>

Why are some groups invisible in X-ray?
<p>We investigate the X-ray properties of z<0.2 GAMA groups and clusters (log M = 13-14.7) in the eFEDS (eROSITA Final Equatorial Depth Survey) area. The stacked surface brightness profile of eROSITA-undetected groups is less concentrated than the mean surface brightness profile of the detected ones, and this is also true of the total mass and galaxy distributions. Undetected groups tend to be younger (as inferred by the 1st to 2nd ranked galaxies magnitude difference), and to host a younger galaxy population. The difference between detected and undetected systems cannot be explained by the AGN activity which is similar for the two classes. Instead, we argue that the difference between detected and undetected systems is due to their location in the cosmic web, which affects the halo formation epoch. Our conclusion is supported by the analysis of the Lx-M relation for the groups of the two classes, as a function of the group location in the cosmic web.</p>
