Primordial Non-Gaussianities (PNG) and zero bias tracers of the Large Scale StructureThe statistical properties of the primordial curvature perturbations are a key ingredient of the success of the LCDM model in explaining the Universe as we observe it today.In simplest model of inflation initial fluctuations are Gaussian for all practical purposes, and measurements of the CMB bispectrum by the Planck satellite ...
In this talk, I will explore the physics of water blocking in unconventional tight formations. Fracturing is necessary to achieve economical production rates in these formations, but a sizable amount of fracturing fluid is left behind in the formation, potentially inhibiting production. Through experimental results, I will show how this ...

Charge order fluctuations in the cuprate superconductor Nd2-xCexCuO4 measured by ultra-high-resolution RIXSCharge order has now been ubiquitously observed in cuprate high-temperature superconductors. However, it remains unclear if the charge order is purely static or whether it also features dynamic correlations. In this talk I will describe a resonant inelastic x-ray scattering (RIXS) experiment on the electron-doped cuprate Nd2-xCexCuO4 that demonstrates the ...

THE MYSTERIOUS MASS OF THE HIGGS BOSONThe discovery of the Higgs boson at the Large Hadron Collider (LHC) in 2012 triumphantly completed the Standard Model of particle physics and opened the experimental program studying this new particle. At the same time, particle experiments are searching for physics beyond the Standard Model, including an those that explain ...

A Neutron Star Merger Seen In Both Gravitational Waves and Light Last August, the discovery of the merger of two neutron stars heralded the first time we have detected both gravitational waves (GW) and light from the same event. Gamma-rays measured only seconds after the GW signal put strong constraints on the speed of gravity. Optical and infrared observations over the ...
In the 21st century, the subsurface environment will be a valuable resource for disposal of greenhouse gases and storage of energy via compressed fluids. Reliable development of these technologies will rely on our ability to predictably describe fluid flow in porous and fractured media, and its evolution in response to ...

Why Algorithmic Systems Possess No UnderstandingMany examples of highly effective algorithmic systems, such as AI devices, have been constructed in recent years. We have computer-controlled machines like self-driving cars and algorithmic systems that play chess and GO at levels that can out-perform even the best of human players. But do such devices actually “understand†what ...

Meet the Neighbors: Searching for Nearby Planets with the Transiting Exoplanet Survey SatelliteThe NASA Kepler mission revealed that our Galaxy is teeming with planetary systems and that Earth-sized planets are common, but most of the planets detected by Kepler orbit stars that are too faint to permit detailed study. Excitingly, the NASA Transiting Exoplanet Survey Satellite (TESS) is scheduled to launch this ...

taste of science: Machining our GenesBenificial Uses for VirusesViruses are nature's way of doing more with less. They're crafty, highly engineerable, infectious parasites with properties that make them ideal drug delivery tools for the clinic. Come hear about different ways viruses can be used to deliver genetic medicines that not only treat, but have begun ...
