Unveiling cosmic voids in large-scale structure surveys: the impact of tracer bias The large-scale structure of the Universe can only be observed directly via luminous tracers of the underlying matter density field. However, luminous tracers, such as galaxies, do not precisely mirror the clustering statistic of the bulk of the cold dark matter distribution: their correlation function (or power spectrum) is biased ...

A Drive for Better Air Service: How air service imbalances across megaregions integrate air and highway demandsBetween 2000 and 2010, newly merged U.S. airlines decreased service to airports in small and mid-sized metropolitan regions, opting to consolidate their operations at high-value airport hubs (passenger transfer points). At this point travelers living in small and mid-sized regions likely began leaking, or abandoning their local airport to take ...

Hyper Suprime-Cam Weak Lensing Measurement of Galaxy Clusters selected by Atacama Cosmology Telescope PolarimeterGalaxy clusters are one of the most powerful cosmological probes because of an exponential tail at the high-mass end of the cluster mass function. The accuracy of mass function measurement is currently limited by systematic uncertainties in cluster mass estimates due to an uncertain physical assumption, e.g., hydrostatic equilibrium when ...

Weak Lensing with Galaxy Clusters - RESCHEDULEDWeak lensing and galaxy cluster abundances are two of the cosmological probes considered to have the most power for upcoming surveys. They have a natural connection via the use of weak lensing to calibrate the masses of galaxy clusters--a critical measurement in order to reach the promised precision of galaxy ...
Flow through fractured media in the sub-surface is heavily dependent on microstructural information. Continuum models often eliminate features critical to accurately predicting macroscale behavior but are commonly used since resolving thousands of fractures individually is computationally intractable. We overcome this hurdle by developing compact graph representations of the fracture networks, ...
