Comments on arXiv:1310.5067: "A response to `A self-consistent public catalogue of voids and superclusters in the SDSS Data Release 7 galaxy surveys' "
Seshadri Nadathur, Shaun Hotchkiss
Sutter et al. have responded to the criticisms we made of their cosmic void catalogue in our recent paper presenting an alternative catalogue (Nadathur & Hotchkiss 2013). Unfortuna…
A robust public catalogue of voids and superclusters in the SDSS Data Release 7 galaxy surveys
Seshadri Nadathur, Shaun Hotchkiss
The study of the interesting cosmological properties of voids in the Universe depends on the efficient and robust identification of such voids in galaxy redshift surveys. Recently,…
The Jubilee ISW Project I: simulated ISW and weak lensing maps and initial power spectra results
W. A. Watson, J. M. Diego, S. Gottlöber +11
We present initial results from the Jubilee ISW project, which models the expected \LambdaCDM Integrated Sachs-Wolfe (ISW) effect in the Jubilee simulation. The simulation volume i…
Seeing patterns in noise: Gigaparsec-scale `structures' that do not violate homogeneity
Seshadri Nadathur
Clowes et al. (2013) have recently reported the discovery of a Large Quasar Group (LQG), dubbed the Huge-LQG, at redshift z~1.3 in the DR7 quasar catalogue of the Sloan Digital Sky…
The stacked ISW signal of rare superstructures in ΛCDM
Samuel Flender, Shaun Hotchkiss, Seshadri Nadathur
A detection of the stacked integrated Sachs-Wolfe (ISW) signal in the CMB of rare superstructures identified in the SDSS Luminous Red Galaxy catalogue has been reported at very hig…
