Augmenting machine learning photometric redshifts with Gaussian mixture models
Jarvis, M; Hatfield, P; Almosallam, I (Oxford University Press, 2020-09-11)Wide-area imaging surveys are one of the key ways of advancing our understanding of cosmology, galaxy formation physics, and the large-scale structure of the Universe in the coming years. These surveys typically require ... -
Evaluation of probabilistic photometric redshift estimation approaches for The Rubin Observatory Legacy Survey of Space and Time (LSST)
Jarvis, M; Schmidt, S; Malz, A (Oxford University Press, 2020-09-14)Many scientific investigations of photometric galaxy surveys require redshift estimates, whose uncertainty properties are best encapsulated by photometric redshift (photo-z) posterior probability density functions (PDFs). ... -
Timing the earliest quenching events with a robust sample of massive quiescent galaxies at 2 < z < 5
Jarvis, M; Carnall, A; Walker, S (Oxford University Press, 2020-06-04)We present a sample of 151 massive (M∗ > 1010 M) quiescent galaxies at 2 <z< 5, based on a sophisticated Bayesian spectral energy distribution fitting analysis of the CANDELS UDS and GOODS-South fields. Our sample includes ... -
VLA imaging of the XMM-LSS/VIDEO deep field at 1–2 GHz
Jarvis, M; Heywood, I; Hale, C (Oxford University Press, 2020-06-20)Modern radio telescopes are routinely reaching depths where normal star-forming galaxies are the dominant observed population. Realizing the potential of radio as a tracer of star formation and black hole activity over ...
