Diffhalos: A Generative Model of Cosmological Lightcones of Dark Matter Halos
Georgios Zacharegkas, Andrew P. Hearin, Alan Pearl +3
We present a generative model of cosmological lightcones of dark matter halos, Diffhalos. In our model, we draw Monte Carlo samples of the halo mass function in a lightcone with a…
DiffstarPop: A generative physical model of galaxy star formation history
Alex Alarcon, Andrew P. Hearin, Matthew R. Becker +3
We present DiffstarPop, a differentiable forward model of cosmological populations of galaxy star formation histories (SFH). In the model, individual galaxy SFH is parametrized by…
The little coadd that could: Estimating shear from coadded images
Robert Armstrong, Erin Sheldon, Eric Huff +9
Upcoming wide field surveys will have many overlapping epochs of the same region of sky. The conventional wisdom is that in order to reduce the errors sufficiently for systematics-…
On the Impact of Cepheid Outliers on the Distance Ladder
M. R. Becker, H. Desmond, E. Rozo +2
Recent work by Efstathiou (2014) highlighted the importance of outliers in the period-luminosity (PL) relation of Cepheid data on the distance ladder. We present a statistical fram…
Cosmology from Cosmic Shear with DES Science Verification Data
The Dark Energy Survey Collaboration, T. Abbott, F. B. Abdalla +126
We present the first constraints on cosmology from the Dark Energy Survey (DES), using weak lensing measurements from the preliminary Science Verification (SV) data. We use 139 squ…
Cosmological Constraints from the Large Scale Weak Lensing of SDSS MaxBCG Clusters
Ying Zu, David H. Weinberg, Eduardo Rozo +3
We derive constraints on the matter density \Om and the amplitude of matter clustering \sig8 from measurements of large scale weak lensing (projected separation R=5-30\hmpc) by clu…
