Quantum yield and charge diffusion in the Nancy Grace Roman Space Telescope infrared detectors

Jahmour J. Givans, Ami Choi, Anna Porredon +6

The shear signal required for weak lensing analyses is small, so any detector-level effects which distort astronomical images can contaminate the inferred shear. The Nancy Grace Ro…

Brighter-fatter effect in near-infrared detectors -- III. Fourier-domain treatment of flat field correlations and application to WFIRST

Jenna K. C. Freudenburg, Jahmour J. Givans, Ami Choi +8

Weak gravitational lensing has emerged as a leading probe of the growth of cosmic structure. However, the shear signal is very small and accurate measurement depends critically on…

A Framework for Measuring Weak-Lensing Magnification Using the Fundamental Plane

Jenna K. C. Freudenburg, Eric M. Huff, Christopher M. Hirata

Galaxy-galaxy lensing is an essential tool for probing dark matter halos and constraining cosmological parameters. While galaxy-galaxy lensing measurements usually rely on shear, w…

The Chemical Abundance Structure of the Inner Milky Way: A Signature of "Upside-Down" Disk Formation?

Jenna K. C. Freudenburg, David H. Weinberg, Michael R. Hayden +1

We present a model for the [alpha/Fe]-[Fe/H] distribution of stars in the inner Galaxy, R=3-5 kpc, measured as a function of vertical distance |z| from the midplane by Hayden et al…

Equilibrium and Sudden Events in Chemical Evolution

David H. Weinberg, Brett H. Andrews, Jenna Freudenburg

We present new analytic solutions for one-zone (fully mixed) chemical evolution models and explore their implications. In contrast to existing analytic models, we incorporate a rea…

Curves defined by Chebyshev polynomials

Gene Freudenburg, Jenna Freudenburg

Working over a field $\kk$ of characteristic zero, this paper studies line embeddings of the form $ϕ= (T_i,T_j,T_k):\A^1\to\A^3$, where denotes the degree Chebyshev polyn…
