The Redshift-Space Cluster-Galaxy Cross-Correlation as a Probe of Gravity on Cosmic Scales
Nicole Marcelina Gountanis, David H. Weinberg, Andrés N. Salcedo +1
Testing General Relativity (GR) on cosmological scales requires probes that are directly sensitive to gravitational dynamics. We present a Fisher matrix forecast of how well the Da…
Are Nucleosynthetic Yields Universal? Interpreting the Multi-Elemental Abundances of Quiescent Galaxies over Cosmic Time Using Milky Way Stars
Aliza G. Beverage, David H. Weinberg, Mariska Kriek +3
The detailed abundance patterns of quiescent galaxies offer powerful constraints on their formation and evolution. Yet physical insight remains elusive, as nucleosynthetic yields a…
Cosmological Constraints from Dark Energy Survey Year 1 Cluster Lensing and Abundances with Simulation-based Forward-Modeling
Andrés N. Salcedo, Eduardo Rozo, Hao-Yi Wu +7
We present a simulation-based forward-modeling framework for cosmological inference from optical galaxy-cluster samples, and apply it to the abundance and weak-lensing signals of D…
Modeling the Ages and Chemical Abundances of Elliptical Galaxies
Nicole Marcelina Gountanis, David H. Weinberg, Aliza G. Beverage +3
Spectroscopic studies of elliptical galaxies show that their stellar population ages, mean metallicity, and -enhancement traced by [Mg/Fe] all increase with galaxy stellar mass…
Dissecting the Crab Nebula with JWST: Pulsar wind, dusty filaments, and Ni/Fe abundance constraints on the explosion mechanism
Tea Temim, J. Martin Laming, P. J. Kavanagh +19
We present JWST observations of the Crab Nebula, the iconic remnant of the historical SN 1054. The observations include NIRCam and MIRI imaging mosaics, plus MIRI/MRS IFU spectra t…
