Einstein's legacy in galaxy surveys
(Oxford University Press, 2015)
Non-Gaussianity in the primordial fluctuations that seeded structure formation produces a signal in the galaxy power spectrum on very large scales. This signal contains vital information about the primordial Universe, but ...
The role of environment in galaxy evolution in the servs survey. I. density maps and cluster candidates
(The American Astronomical Society, 2020)
We use photometric redshifts derived from new u-band through 4.5 μm Spitzer IRAC photometry in the 4.8 deg2 of
the XMM-LSS field to construct surface density maps in the redshift range of 0.1–1.5. Our density maps ...
Cosmology with a SKA HI intensity mapping survey
(Proceedings of Science, 2014)
HI intensity mapping (IM) is a novel technique capable of mapping the large-scale structure of
the Universe in three dimensions and delivering exquisite constraints on cosmology, by using HI
as a biased tracer of the ...
Overview of Cosmology with the SKA
(Proceedings of Science, 2014)
The new frontier of cosmology will be led by three-dimensional surveys of the large-scale structure of the Universe. Based on its all-sky surveys and redshift depth, the SKA is destined to revolutionize cosmology, in ...
Finding universal relations in Subhalo properties with artificial intelligence
(The Astrophysical Journal, 2022)
We use a generic formalism designed to search for relations in high-dimensional spaces to determine if the total mass of a subhalo can be predicted from other internal properties such as velocity dispersion, radius, or ...
