Improving photometric redshift estimation using GPz: size information, post processing and improved photometry
Gomes, Zahra; Jarvis, Matt; Almosallam, Ibrahim A.; Roberts, Stephen J. (Oxford University Press, 2017)The next generation of large-scale imaging surveys (such as those conducted with the Large Synoptic Survey Telescope and Euclid) will require accurate photometric redshifts in order to optimally extract cosmological ... -
Non-Gaussianity constraints using future radio continuum surveys and the multitracer technique
Camera, Stefano; Gomes, Zahra; Jarvis, Matt J. (Oxford University Press, 2019)Tighter constraints on measurements of primordial non-Gaussianity (PNG) will allow the differentiation of inflationary scenarios. The cosmic microwave background bispectrum – the standard method of measuring the local ...
