Future continuum surveys
A significant population of distant sub-millimeter-selected galaxies (SMGs) with powerful dust continuum emission that matches the luminosity of the brightest QSOs and exceeds that of most extreme local galaxies detected by IRAS, has been known for almost a decade. The full range of powerful groundand space-based facilities have been used to investigate them, and a good deal of information abou...
متن کاملLarge-Scale Structure & Future Surveys
As the 2dF Galaxy Redshift Survey and Sloan Digital Sky Survey move toward completion, it is time to ask what the next generation of survey of large-scale structure should be. I discuss some of the cosmological justifications for such surveys and conclude that surveys at z = 3 offer a critical advantage in their ability to access linear-regime clustering at scales smaller than any current surve...
متن کاملNeutrino physics from future weak lensing surveys
Given recent indications of additional neutrino species and cosmologically significant neutrino masses, we analyze their signatures in the weak lensing shear power spectrum. We find that a shear deficit in the 20-40% range or excess in the 20-80% range cannot be explained by variations in parameters of the flat ΛCDM model that are allowed by current observations of the expansion history from Ty...
متن کاملThe future of census coverage surveys
A quarter-century of statistical research has shown that census coverage surveys, valuable as they are in offering a report card on each decennial census, do not provide usable estimates of geographical differences in coverage. The determining reason is the large number of “doubly missing” people missing both from the census enumeration and from coverage survey estimates. Future coverage survey...
متن کاملProbing dark energy with future surveys
I review the observational prospects to constrain the equation of state parameter of dark energy and I discuss the potential of future imaging and redshift surveys. Bayesian model selection is used to address the question of the level of accuracy on the equation of state parameter that is required before explanations alternative to a cosmological constant become very implausible. I discuss resu...
