Non-Gaussianity effects on the primordial black hole abundance for sharply-peaked primordial spectrum

Kavli Affiliate: Misao Sasaki | First 5 Authors: Takahiko Matsubara, Misao Sasaki, , , | Summary: We perturbatively study the effect of non-Gaussianities on the mass fraction of primordial black holes (PBHs) at the time of formation by systematically taking its effect into account in the one-point probability distribution function of the primordial curvature perturbation. […]

A Stress Induced Source of Phonon Bursts and Quasiparticle Poisoning

Kavli Affiliate: Noah Kurinsky | First 5 Authors: Robin Anthony-Petersen, Andreas Biekert, Raymond Bunker, Clarence L. Chang, Yen-Yung Chang | Summary: The performance of superconducting qubits is degraded by a poorly characterized set of energy sources breaking the Cooper pairs responsible for superconductivity, creating a condition often called “quasiparticle poisoning". Both superconducting qubits and low […]

Production of brain-derived neurotrophic factor gates plasticity in developing visual cortex

Kavli Affiliate: Michael Stryker | Authors: Megumi Kaneko and Michael P Stryker | Summary: Abstract We have previously shown that recovery of visual responses to a deprived eye during the critical period in mouse primary visual cortex (V1) requires both export of mRNA encoding brain derived neurotrophic factor (BDNF) to the dendrites of cortical cells […]

Modeling Dust Production, Growth, and Destruction in Reionization-Era Galaxies with the CROC Simulations: Methods and Parameter Exploration

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Clarke J. Esmerian, Nickolay Y. Gnedin, , , | Summary: We introduce a model for the explicit evolution of interstellar dust in a cosmological galaxy formation simulation. We post-process a simulation from the Cosmic Reionization on Computers project (CROC, Gnedin 2014), integrating an ordinary differential equation […]

Exploring $boldsymbol{2+2}$ Answers to $boldsymbol{3+1}$ Questions

Kavli Affiliate: Austin Joyce | First 5 Authors: Jonathan J. Heckman, Austin Joyce, Jeremy Sakstein, Mark Trodden, | Summary: We explore potential uses of physics formulated in Kleinian (i.e., $2+2$) signature spacetimes as a tool for understanding properties of physics in Lorentzian (i.e., $3+1$) signature. Much as Euclidean (i.e., $4+0$) signature quantities can be used […]
