Bayesian “Deep” Process Convolutions: An Application in Cosmology

Kavli Affiliate: Salman Habib | First 5 Authors: Kelly R. Moran, Richard Payne, Earl Lawrence, David Higdon, Stephen A. Walsh | Summary: The nonlinear matter power spectrum in cosmology describes how matter density fluctuations vary with scale in the universe, providing critical insights into large-scale structure formation. The matter power spectrum includes both smooth regions […]

MAGAZ3NE: Evidence for Galactic Conformity in $zgtrsim3$ Protoclusters

Kavli Affiliate: Michael McDonald | First 5 Authors: Ian McConachie, Gillian Wilson, Ben Forrest, Z. Cemile Marsan, Adam Muzzin | Summary: We examine the quiescent fractions of massive galaxies in six $zgtrsim3$ spectroscopically-confirmed protoclusters in the COSMOS field, one of which is newly confirmed and presented here. We report the spectroscopic confirmation of MAGAZ3NE~J100143+023021 at […]

Platinum Black for stray-light mitigation on high-aspect-ratio micromechanical cantilever

Kavli Affiliate: Giorgio Gratta | First 5 Authors: Gautam Venugopalan, Giorgio Gratta, , , | Summary: Microscopic devices are widely used in optomechanical experiments at the cutting-edge of precision experimental physics. Such devices often need to have high electrical conductivity but low reflectivity at optical wavelengths, which can be competing requirements for many commonly available […]

Aeos: Transport of Metals from Minihalos following Population III Stellar Feedback

Kavli Affiliate: Anna Frebel | First 5 Authors: , , , , | Summary: We investigate how stellar feedback from the first stars (Population III) distributes metals through the interstellar and intergalactic medium using the star-by-star cosmological hydrodynamics simulation, Aeos. We find that energy injected from the supernovae of the first stars is enough to […]

Constraining the Binarity of Massive Black Holes in the Galactic Center and Some Nearby Galaxies via Pulsar Timing Array Observations of Gravitational Waves

Kavli Affiliate: Qingjuan Yu | First 5 Authors: Xiao Guo, Qingjuan Yu, Youjun Lu, , | Summary: Massive black holes (MBHs) exist in the Galactic center (GC) and other nearby galactic nuclei. As natural outcome of galaxy mergers, some MBHs may have a black hole (BH) companion. In this paper, assuming that the MBHs in […]
