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 ... -
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 ... -
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 ... -
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 ... -
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 ...
