Astrometry and Occultation predictions to Trans-Neptunian and Centaur Objects observed within the Dark Energy Survey

Posted by Chicago

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 […]

Nonlocal Entanglement and Directional Correlations of Primordial Perturbations on the Inflationary Horizon

Posted by Chicago

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 […]

Global Simulations of Protoplanetary Disk Outflows with Coupled Non-ideal Magnetohydrodynamics and Consistent Thermochemistry

Posted by Peking

Kavli Affiliate: Lile Wang | First 5 Authors: Lile Wang, Xue-Ning Bai, Jeremy Goodman, , | Summary: Magnetized winds may be important in dispersing protoplanetary disks and influencing planet formation. We carry out global full magnetohydrodynamic simulations in axisymmetry, coupled with ray-tracing radiative transfer, consistent thermochemistry, and non-ideal MHD diffusivities. Magnetized models lacking EUV photons […]

Value of the Cosmological Constant in Emergent Quantum Gravity

Posted by Chicago

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 […]
