A Giant Ring on the sky
Alexia M. Lopez, Roger G. Clowes
We present the discovery of `A Giant Ring on the Sky' (GR); a ring-like, ultra-large-scale structure at z~0.8, located in the same field that contains the previously-documented Gia…
Gigaparsec structures are nowhere to be seen in CDM: an enhanced analysis of LSS in FLAMINGO-10K simulations
A. M Lopez, R. G. Clowes
Recently, Sawala et al. 2025 claimed to refute the cosmological significance of the Giant Arc based on their analysis of the FLAMINGO-10K simulation data. In our paper here, we hig…
Investigating Ultra-Large Large-Scale Structures: Potential Implications for Cosmology
Alexia M. Lopez, Roger G. Clowes, Gerard M. Williger
Large-scale structure (LSS) studies in cosmology map and analyse matter in the Universe on the largest scales. Understanding the LSS can provide observational support for the Cosmo…
A Big Ring on the Sky
Alexia M. Lopez, Roger G. Clowes, Gerard M. Williger
We present the discovery of `A Big Ring on the Sky' (BR), the second ultra-large large-scale structure (uLSS) found in MgII-absorber catalogues, following the previously reported G…
Is the Observable Universe Consistent with the Cosmological Principle?
Pavan Kumar Aluri, Paolo Cea, Pravabati Chingangbam +20
The Cosmological Principle (CP) -- the notion that the Universe is spatially isotropic and homogeneous on large scales -- underlies a century of progress in cosmology. It is conven…
Correlated orientations of the axes of large quasar groups on Gpc scales
Tracey Friday, Roger G. Clowes, Gerard M. Williger
Correlated orientations of quasar optical and radio polarisation, and of radio jets, have been reported on Gpc scales, possibly arising from intrinsic alignment of spin axes. Optic…
