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 […]
Kavli Affiliate: Alexander Ji | First 5 Authors: Alexander P. Ji, Anna Frebel, , , | Summary: The ultra-faint dwarf galaxy Reticulum II was enriched by a rare and prolific r-process event, such as a neutron star merger. To investigate the nature of this event, we present high-resolution Magellan/MIKE spectroscopy of the brightest star in […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Gordan Krnjaic, , , , | Summary: Freeze-in dark matter (DM) mediated by a light ($ll$ keV) weakly-coupled dark-photon is an important benchmark for the emerging low-mass direct detection program. Since this is one of the only predictive, detectable freeze-in models, we investigate how robustly such testability […]
Kavli Affiliate: Savdeep Sethi | First 5 Authors: Savdeep Sethi, , , , | Summary: Type II string theory and M-theory admit flux configurations that break supersymmetry below the Kaluza-Klein scale. These backgrounds play a central role in most models of the string landscape. I argue that the behavior of such backgrounds at weak coupling […]
Kavli Affiliate: Jeffrey John McMahon | First 5 Authors: Sean Bryan, Peter Ade, J. Richard Bond, Francois Boulanger, Mark Devlin | Summary: BFORE is a NASA high-altitude ultra-long-duration balloon mission proposed to measure the cosmic microwave background (CMB) across half the sky during a 28-day mid-latitude flight launched from Wanaka, New Zealand. With the unique […]
Kavli Affiliate: Richard Kessler | First 5 Authors: Richard Kessler, Dan Scolnic, , , | Summary: We present a new technique to create a bin-averaged Hubble Diagram (HD) from photometrically identified SN~Ia data. The resulting HD is corrected for selection biases and contamination from core collapse (CC) SNe, and can be used to infer cosmological […]
Kavli Affiliate: Elise Jennings | First 5 Authors: Elise Jennings, Maeve Madigan, , , | Summary: Given the complexity of modern cosmological parameter inference where we are faced with non-Gaussian data and noise, correlated systematics and multi-probe correlated data sets, the Approximate Bayesian Computation (ABC) method is a promising alternative to traditional Markov Chain Monte […]
Kavli Affiliate: Austin Joyce | First 5 Authors: Kurt Hinterbichler, Austin Joyce, , , | Summary: In four dimensions, partially massless fields of all spins and depths possess a duality invariance akin to electric-magnetic duality. We construct metric-like gauge invariant curvature tensors for partially massless fields of all integer spins and depths, and show how […]
Kavli Affiliate: Jeffrey McMahon | First 5 Authors: Jeffrey M. McMahon, , , , | Summary: Density-functional theory is a formally exact description of a many-body quantum system in terms of its density; in practice, however, approximations to the universal density functional are required. In this work, a model based on deep learning is developed […]
