Cosmic Himalayas Reconciled with Lambda CDM

This paper addresses the apparent tension between the observed extreme quasar overdensity, the 'Cosmic Himalayas,' and the standard Lambda CDM cosmological model. It uses the CROCODILE simulation to investigate quasar clustering, employing count-in-cells and nearest-neighbor distribution analyses. The key finding is that the significance of the overdensity is overestimated when using Gaussian statistics. By employing a more appropriate asymmetric generalized normal distribution, the authors demonstrate that the 'Cosmic Himalayas' are not an anomaly, but a natural outcome within the Lambda CDM framework.
