Kavli Affiliate: Jeffrey A. Harvey | First 5 Authors: Jeffrey A. Harvey, , , , | Summary: Ramanujan influenced many areas of mathematics, but his work on q-series, on the growth of coefficients of modular forms, and on mock modular forms stands out for its depth and breadth of applications. I will give a brief […]
Kavli Affiliate: Karen Byrum | First 5 Authors: Kevork Abazajian, Graeme Addison, Peter Adshead, Zeeshan Ahmed, Steven W. Allen | Summary: We provide an overview of the science case, instrument configuration and project plan for the next-generation ground-based cosmic microwave background experiment CMB-S4, for consideration by the 2020 Decadal Survey. | Search Query: ArXiv Query: […]
Kavli Affiliate: Nickolay Gnedin | First 5 Authors: Nickolay Y. Gnedin, , , , | Summary: I describe a modification to the original Fast Multipole Method (FMM) of Greengard & Rokhlin that approximates the gravitation field of an FMM cell as a small uniform grid (a "gridlet") of effective masses. The effective masses on a […]
Kavli Affiliate: Bradford A. Benson | First 5 Authors: Zhaodi Pan, Mira Liu, Ritoban Basu Thakur, Bradford A. Benson, Dale J. Fixsen | Summary: We have constructed a Fourier-transform spectrometer (FTS) operating between 50 and 330 GHz with minimum volume (355 x260 x64 mm) and weight (13 lbs) while maximizing optical throughput (100 $mathrm{mm}^2$ sr) […]
Kavli Affiliate: Luca Grandi | First 5 Authors: Daniel Ahlin, Boris Bauermeister, Jan Conrad, Robert Gardner, Luca Grandi | Summary: The XENON experiment is looking for non-baryonic particle dark matter in the universe. The setup is a dual phase time projection chamber (TPC) filled with 3200 kg of ultra-pure liquid xenon. The setup is operated […]
Kavli Affiliate: Nickolay Gnedin | First 5 Authors: Enrico Garaldi, Nickolay Gnedin, Piero Madau, , | Summary: We investigate Lyman-$alpha$ transmission spikes at $z > 5$ in synthetic quasar spectra, and discuss their connection to the properties of the intergalactic medium and their ability to constrain reionization models. We use state-of-the-art radiation-hydrodynamic simulations from the […]
Kavli Affiliate: Alex Drlica Wagner | First 5 Authors: Martin Banda-Huarca, Julio Camargo, Josselin Desmars, Ricardo Ogando, Roberto Vieira-Martins | Summary: Transneptunian objects (TNOs) are a source of invaluable information to access the history and evolution of the outer solar system. However, observing these faint objects is a difficult task. As a consequence, important properties […]
Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, , , , | Summary: Models are developed to estimate properties of relic cosmic perturbations with "spooky" nonlocal correlations on the inflationary horizon, analogous to those previously posited for information on black hole event horizons. Scalar curvature perturbations are estimated to emerge with a dimensionless […]
Kavli Affiliate: Thomas M. Crawford | First 5 Authors: John E. Carlstrom, Thomas M. Crawford, Lloyd Knox, , | Summary: Temperature and polarization variations across the microwave sky include the fingerprints of quantum fluctuations in the early universe. They may soon reveal physics at unprecedented energy scales. | Search Query: arXiv Query: search_query=au:”Thomas M. Crawford”&id_list=&start=0&max_results=3 […]
Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, , , , | Summary: It is suggested that the exact value of the cosmological constant could be derived from first principles, based on entanglement of the Standard Model field vacuum with emergent holographic quantum geometry. For the observed value of the cosmological constant, geometrical […]
