Diffstar: A Fully Parametric Physical Model for Galaxy Assembly History
Alex Alarcon, Andrew P. Hearin, Matthew R. Becker +1
We present Diffstar, a smooth parametric model for the in-situ star formation history (SFH) of galaxies. Diffstar is distinct from conventional SFH models that are used to interpre…
Snowmass2021 Cosmic Frontier White Paper: High Density Galaxy Clustering in the Regime of Cosmic Acceleration
Kyle Dawson, Andrew Hearin, Katrin Heitmann +4
Joint studies of imaging and spectroscopic samples, informed by theory and simulations, offer the potential for comprehensive tests of the cosmological model over redshifts z<1.5.…
Snowmass2021: Opportunities from Cross-survey Analyses of Static Probes
Eric J. Baxter, Chihway Chang, Andrew Hearin +37
Cosmological data in the next decade will be characterized by high-precision, multi-wavelength measurements of thousands of square degrees of the same patches of sky. By performing…
