“Worst-Case” Micro-Lensing in the Identification and Modeling of Lensed Quasars

Kavli Affiliate: Paul Schechter | First 5 Authors: Luke Weisenbach, Paul Schechter, Sahil Pontula, , | Summary: Although micro-lensing of macro-lensed quasars and supernovae provides unique opportunities for several kinds of investigations, it can add unwanted and sometimes substantial noise. While micro-lensing flux anomalies may be safely ignored for some observations, they severely limit others. […]

Inferring simple but precise quantitative models of human oocyte and early embryo development

Kavli Affiliate: Daniel Needleman | First 5 Authors: Brian D Leahy, Catherine Racowsky, Daniel Needleman, , | Summary: Macroscopic, phenomenological models have proven useful as concise framings of our understandings in fields from statistical physics to economics to biology. Constructing a phenomenological model for development would provide a framework for understanding the complicated, regulatory nature […]

Accurate Measurement of the Gap of Graphene/hBN Moiré Superlattice through Photocurrent Spectroscopy

Kavli Affiliate: Paul L. McEuen | First 5 Authors: Tianyi Han, Jixiang Yang, Qihang Zhang, Lei Wang, Kenji Watanabe | Summary: Monolayer graphene aligned with hexagonal boron nitride (hBN) develops a gap at the charge neutrality point (CNP). This gap has previously been extensively studied by electrical transport through thermal activation measurements. Here, we report […]

Effects of overlapping sources on cosmic shear estimation: Statistical sensitivity and pixel-noise bias

Kavli Affiliate: Patricia R. Burchat | First 5 Authors: Javier Sanchez, Ismael Mendoza, David P. Kirkby, Patricia R. Burchat, | Summary: In Stage-IV imaging surveys, a significant amount of the cosmologically useful information is due to sources whose images overlap with those of other sources on the sky. The cosmic shear signal is primarily encoded […]

Vibrational relaxation dynamics in layered perovskite quantum wells

Kavli Affiliate: Peidong Yang | First 5 Authors: Li Na Quan, Yoonjae Park, Peijun Guo, Mengyu Gao, Jianbo Jin | Summary: Organic-inorganic layered perovskites are two-dimensional quantum wells with layers of lead-halide octahedra stacked between organic ligand barriers. The combination of their dielectric confinement and ionic sublattice results in excitonic excitations with substantial binding energies […]

Discovery of soft and hard X-ray time lags in low-mass AGNs

Kavli Affiliate: Daniel R. Wilkins | First 5 Authors: Labani Mallick, Daniel R. Wilkins, William N. Alston, Alex Markowitz, Barbara De Marco | Summary: The scaling relations between the black hole (BH) mass and soft lag properties for both active galactic nuclei (AGNs) and BH X-ray binaries (BHXRBs) suggest the same underlying physical mechanism at […]
