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…
A High Precision Survey of the D/H Ratio in the Nearby Interstellar Medium
S. D. Friedman, P. Chayer, E. B. Jenkins +4
We present high S/N measurements of the H I Ly alpha absorption line toward 16 Galactic targets which are at distances between approximately 190 and 2200 pc, all beyond the wall of…
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…
A Giant Arc on the Sky
Alexia M. Lopez, Roger G. Clowes, Gerard M. Williger
We present the serendipitous discovery of a `Giant Arc on the Sky' at . The Giant Arc (GA) spans Gpc (proper size, present epoch), and appears to be almost sym…
The X-ray variable sky as seen by MAXI: the future of dust echo tomography with bright Galactic X-ray bursts
Lia Corrales, Brianna S. Mills, Sebastian Heinz +1
Bright, short duration X-ray flares from accreting compact objects produce thin, dust scattering rings that enable dust echo tomography: high precision distance measurements and ma…
