Kavli Affiliate: Nickolay Gnedin | First 5 Authors: Nishant Mishra, Nickolay Gnedin, , , | Summary: We explore the evolution of the flux power spectrum in the Cosmic Reionization On Computers (CROC) simulations. We find that, contrary to some previous studies, the shape of the flux power spectrum is rather insensitive to the timing of […]
Kavli Affiliate: Emil J. Martinec | First 5 Authors: Emil J. Martinec, , , , | Summary: This companion paper to arXiv:2109.00065 explores the interpretation of $AdS_3/CFT_2$ duality for $k=(R_{AdS}/lstr)^2<1$ in terms of "non-critical little string theory". We review the underlying fivebrane structure of 1/2-BPS backgrounds for string theory in both the critical dimension and […]
Kavli Affiliate: Savdeep Sethi | First 5 Authors: Christian Ferko, Gautam Satishchandran, Savdeep Sethi, , | Summary: We develop a general formalism for treating radiative degrees of freedom near $mathscr{I}^{+}$ in theories with an arbitrary Ricci-flat internal space. These radiative modes are encoded in a generalized news tensor which decomposes into gravitational, electromagnetic, and scalar […]
Kavli Affiliate: Stephan S. Meyer | First 5 Authors: Craig Hogan, Stephan S. Meyer, , , | Summary: We consider the hypothesis that nonlocal, omnidirectional, causally-coherent quantum entanglement of inflationary horizons may account for some well-known measured anomalies of Cosmic Microwave Background (CMB) anisotropy on large angular scales. It is shown that causal coherence can […]
Kavli Affiliate: Jeffrey A. Harvey | First 5 Authors: John F. R. Duncan, Jeffrey A. Harvey, Brandon C. Rayhaun, , | Summary: As Mathieu moonshine is a special case of umbral moonshine, Thompson moonshine (in half-integral weight) is a special case of a family of similar relationships between finite groups and vector-valued modular forms of […]
Kavli Affiliate: Brian Nord | First 5 Authors: Dimitrios Tanoglidis, Aleksandra Ćiprijanović, Alex Drlica-Wagner, Brian Nord, Michael H. L. S. Wang | Summary: Wide-field astronomical surveys are often affected by the presence of undesirable reflections (often known as "ghosting artifacts" or "ghosts") and scattered-light artifacts. The identification and mitigation of these artifacts is important for […]
Kavli Affiliate: Angela Olinto | First 5 Authors: Sameer Patel, Mary Hall Reno, Yosui Akaike, Luis Anchordoqui, Douglas Bergman | Summary: An accurate modeling of neutrino flux attenuation and the distribution of leptons they produce in transit through the Earth is an essential component to determine neutrino flux sensitivities of underground, sub-orbital and space-based detectors. […]
Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Huanqing Chen, Nickolay Y. Gnedin, Philip Mansfield, , | Summary: Using a suite of self-similar cosmological simulations, we measure the probability distribution functions (PDFs) of real-space density, redshift-space density, and their geometric mean. We find that the real-space density PDF is well-described by a function of […]
Kavli Affiliate: Salman Habib | First 5 Authors: Nicholas Frontiere, Katrin Heitmann, Esteban Rangel, Patricia Larsen, Adrian Pope | Summary: In this paper we introduce the Farpoint simulation, the latest member of the Hardware/Hybrid Accelerated Cosmology Code (HACC) gravity-only simulation family. The domain covers a volume of (1000$h^{-1}$Mpc)$^3$ and evolves close to two trillion particles, […]
Kavli Affiliate: Michael S. Turner | First 5 Authors: Michael S. Turner, , , , | Summary: The $rmLambda$CDM cosmological model is remarkable: with just 6 parameters it describes the evolution of the Universe from a very early time when all structures were quantum fluctuations on subatomic scales to the present, and it is consistent […]
