The des view of the Eridanus supervoid and the CMB cold spot
Kovács, A.; Jeffrey, N.; Gatti, M.; Chang, C.; Whiteway, L.; Hamaus, N.; Lahav, O.; Pollina, G.; Bacon, D.; Kacprzak, T.; Mawdsley, B.; Nadathur, S.Made available in DSpace on 2022-04-29T08:41:10Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-02-01; The Cold Spot is a puzzling large-scale feature in the Cosmic Microwave Background temperature maps and its origin has been subject to active debate. As an important foreground structure at low redshift, the Eridanus supervoid was recently detected, but it was subsequently determined that, assuming the ...
Dark Energy Survey Year 3 results: Curved-sky weak lensing mass map reconstruction
Jeffrey, N.; Gatti, M.; Chang, C.; Whiteway, L.; Demirbozan, U.; Kovacs, A.; Pollina, G.; Bacon, D.; Hamaus, N.; Kacprzak, T.; Lahav, O.; Lanusse, F.Made available in DSpace on 2022-04-29T08:30:11Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-08-01; We present reconstructed convergence maps, mass maps, from the Dark Energy Survey (DES) third year (Y3) weak gravitational lensing data set. The mass maps are weighted projections of the density field (primarily dark matter) in the foreground of the observed galaxies. We use four reconstruction methods,...
