Data-driven, interpretable photometric redshifts trained on heterogeneous and unrepresentative data
Boris Leistedt, David W. Hogg
We present a new method for inferring photometric redshifts in deep galaxy and quasar surveys, based on a data driven model of latent spectral energy distributions (SEDs) and a phy…
Unbiased pseudo-Cl power spectrum estimation with mode projection
Franz Elsner, Boris Leistedt, Hiranya V. Peiris
With the steadily improving sensitivity afforded by current and future galaxy surveys, a robust extraction of two-point correlation function measurements may become increasingly ha…
Science Impacts of the SPHEREx All-Sky Optical to Near-Infrared Spectral Survey: Report of a Community Workshop Examining Extragalactic, Galactic, Stellar and Planetary Science
Olivier Doré, Michael W. Werner, Matt Ashby +65
SPHEREx is a proposed SMEX mission selected for Phase A. SPHEREx will carry out the first all-sky spectral survey and provide for every 6.2" pixel a spectra between 0.75 and 4.18 $…
Spin-SILC: CMB polarisation component separation with spin wavelets
Keir K. Rogers, Hiranya V. Peiris, Boris Leistedt +2
We present Spin-SILC, a new foreground component separation method that accurately extracts the cosmic microwave background (CMB) polarisation and modes from raw multifrequ…
Wavelet reconstruction of E and B modes for CMB polarisation and cosmic shear analyses
Boris Leistedt, Jason D. McEwen, Martin Büttner +1
We present new methods for mapping the curl-free (E-mode) and divergence-free (B-mode) components of spin 2 signals using spin directional wavelets. Our methods are equally applica…
Hierarchical Bayesian inference of galaxy redshift distributions from photometric surveys
Boris Leistedt, Daniel J. Mortlock, Hiranya V. Peiris
Accurately characterizing the redshift distributions of galaxies is essential for analysing deep photometric surveys and testing cosmological models. We present a technique to simu…
SILC: a new Planck Internal Linear Combination CMB temperature map using directional wavelets
Keir K. Rogers, Hiranya V. Peiris, Boris Leistedt +2
We present new clean maps of the CMB temperature anisotropies (as measured by Planck) constructed with a novel internal linear combination (ILC) algorithm using directional, scale-…
