The Hubble tension has now grown to a level of significance which can no longer be
ignored and calls for a solution which, despite a huge number of attempts, has so far eluded …

We present evidence for a suppressed growth rate of large-scale structure during the dark-
energy-dominated era. Modeling the growth rate of perturbations with the “growth index” γ …

The current standard cosmological model is constructed within the framework of general
relativity with a cosmological constant Λ, which is often associated with dark energy, and …

The redistribution of baryonic matter in massive haloes through processes like active
galactic nuclei feedback and star formation leads to a suppression of the matter power …

$\Lambda $ CDM tensions are by definition model dependent; one sees anomalies through
the prism of $\Lambda $ CDM. Thus, progress towards tension resolution necessitates …

The cluster mass function traces the growth of linear density perturbations and provides
valuable insights into the growth of structures, the nature of dark matter, and the …

The statistics of thermal gas pressure are a new and promising probe of cosmology and
astrophysics. The large-scale cross-correlation between galaxies and the thermal Sunyaev …

We present the discovery ofA Big Ring on the Sky'(BR), the second ultra-large-scale
structure (uLSS) found in MgII-absorber catalogues, following the previously reported Giant …

The discovery of cosmic acceleration has stimulated theorists to consider dark energy or
modifications to Einstein's General Relativity as possible explanations. The last decade has …

Recent works have discovered a relatively tight correlation between Ω m and the properties
of individual simulated galaxies. Because of this, it has been shown that constraints on Ω m …
