Diagnosing the Effects of Spectroscopic Training Set Imperfection on Photometric Redshift Performance

Alice Crafford, Alex I. Malz, Tianqing Zhang +11

Most LSST extragalactic science will rely on photometric redshifts (photo-) to extract distance information for the galaxies. However, an incomplete or non-representative traini…

Weak lensing mass-richness relation of redMaPPer clusters in the LSST DESC DC2 simulations

Constantin Payerne, Zhuowen Zhang, Michel Aguena +13

Cluster scaling relations are key ingredients in cluster abundance-based cosmological studies. In optical cluster cosmology, where clusters are detected through their richness, clu…

Blending and obscuration in weak lensing magnification

E. Gaztanaga, S. J. Schmidt, M. D. Schneider +1

We test the impact of some systematic errors in weak lensing magnification measurements with the COSMOS 30-band photo- Survey flux limited to using correlations…

Estimating Sky Level

Inchan Ji, Imran Hasan, Samuel J. Schmidt +1

We develop an improved sky background estimator which employs optimal filters for both spatial and pixel intensity distributions. It incorporates growth of masks around detected ob…

Photometric Redshifts with the LSST: Evaluating Survey Observing Strategies

Melissa L. Graham, Andrew J. Connolly, Željko Ivezić +5

In this paper we present and characterize a nearest-neighbors color-matching photometric redshift estimator that features a direct relationship between the precision and accuracy o…
