U15.00001: Joining Forces against the Dark Universe: New Results from Spectroscopic Surveys Invited Speaker: Shirley HO Despite tremendous recent progress, gaps remain in our knowledge of our understanding of the Universe.| We have not yet pinned down the properties of dark energy, nor have we confirmed Einstein's theory of Gravity at the largest scales.Current and upcoming large sky surveys of Large Scale Structure (LSS) in galaxies, quasars and Lyman-alpha forest present us with the best opportunity to understand| properties of the Universe. I will first review recent cosmology results from Large Scale Structure, concentrating on BOSS and preliminary eBOSS results using Baryon Acoustic Oscillations and Redshift Space Distortions. I will then introduce novel cosmological probes which combine Cosmic Microwave Background with LSS directly. These novel probes will open new windows into the momentum field of the Universe and Gravity at the largest scales.| I will finally put these into the context of upcoming surveys such as Dark Energy Spectroscopic Instrument (DESI), Wide Field Infrared Survey Telescope (WFIRST) and CMB S4.

U15.00003: Our warped universe: the power of gravitational lensing for probing the cosmos Invited Speaker: Brian Nord Gravitational lensing epitomizes a maxim of Einstein's General Relativity: space tells energy how to move and energy tells space how to curve. Through lensing, massive objects magnify and distort the shapes of distant objects, likes galaxies and quasars. The connection between the lens's mass distribution and the degree of distortion in the images allows us to observe faint, distant objects, and to infer the matter distribution and cosmic expansion in the nearby universe. Current and future surveys, both ground- and space-based, will provide data sets unprecedented in size and precision with which to probe dark energy, dark matter and the early universe through gravitational lensing. I will discuss recent advances in observations and analysis techniques in both weak and strong lensing, and the burgeoning potential of these techniques to derive important and competitive cosmological constraints from surveys of large-scale structure.
