Updated Constraints on Infrared Cutoff Models and Implications for Large-Scale CMB Anomalies. Ujjwal Upadhyay et. al. https://arxiv.org/abs/2602.16659
Best-fit residual CMB power spectra for temperature, polarisation, and their cross-correlation at large multipoles for the different IR cut-off models using parameter values from Table {tab: cmb-constraints Posterior distributions of the anomaly statistics associated with the low quadrupole amplitude $C_2$ and the parity asymmetry statistic $P$. The left panel shows the joint posterior distribution for the ‘true theory’ conditioned on the observed sky under the assumption of statistical isotropy and...

Investigating Nonlinear Quenching Effects on Polar Field Buildup in the Sun Using Physics-Informed Neural Networks. Jithu J. Athalathil et. al. https://arxiv.org/abs/2602.16656
Figure 1 Distribution of errors for the PINNs model (teal) and Talafha et al. (crimson) across different metrics. Violin plots illustrate the full distributions of the errors, while overlaid boxplots highlight the median (horizontal line), mean (black circle), and interquartile range (box) for each metric.
