CCCP and MENeaCS: (updated) weak-lensing masses for 100 galaxy clusters
Ricardo Herbonnet, Cristóbal Sifón, Henk Hoekstra +7
Large area surveys have detected significant samples of galaxy clusters that can be used to constrain cosmological parameters, provided that the masses of the clusters are measured…
The PAU Survey: Background light estimation with deep learning techniques
Laura Cabayol-Garcia, Martin B. Eriksen, Àlex Alarcón +17
In any imaging survey, measuring accurately the astronomical background light is crucial to obtain good photometry. This paper introduces BKGnet, a deep neural network to predict t…
The impact of the observed baryon distribution in haloes on the total matter power spectrum
Stijn N. B. Debackere, Joop Schaye, Henk Hoekstra
The interpretation of upcoming weak gravitational lensing surveys depends critically on our understanding of the matter power spectrum on scales , where bary…
Optical follow-up study of 32 high-redshift galaxy cluster candidates from Planck with the William Herschel Telescope
Hannah Zohren, Tim Schrabback, Remco F. J. van der Burg +5
The Planck satellite has detected cluster candidates via the Sunyaev Zel'dovich (SZ) effect, but the optical follow-up required to confirm these candidates is still incomplete, esp…
KiDS+VIKING-450 and DES-Y1 combined: Cosmology with cosmic shear
S. Joudaki, H. Hildebrandt, D. Traykova +12
We present a combined tomographic weak gravitational lensing analysis of the Kilo Degree Survey (KV450) and the Dark Energy Survey (DES-Y1). We homogenize the analysis of these two…
GAMA+KiDS: Alignment of galaxies in galaxy groups and its dependence on galaxy scale
Christos Georgiou, Nora Elisa Chisari, Maria Cristina Fortuna +11
Intrinsic galaxy alignments are a source of bias for weak lensing measurements as well as a tool for understanding galaxy formation and evolution. In this work, we measure the alig…
