Framing effects in disaster risk communication: the case of coastal erosion in the United States Open
Governments have the duty to protect their citizens and to prevent natural hazards from turning into disasters. Therefore, they need to communicate effectively about disaster risk to potentially affected populations. We conducted three onl…

Gaps review and improvement pathways in the assessment and management of collision risk in low Earth orbit Open
There is growing concern that collision risk in low Earth orbit is inadequately managed, necessitating new strategies. Based on discussions held at a multistakeholder workshop organized by EPFL in May 2021, this paper presents some challen…

Dark Energy Survey Year 3 Results: Deep Field optical + near-infrared images and catalogue Open
We describe the Dark Energy Survey (DES) Deep Fields, a set of images and associated multiwavelength catalogue (ugrizJHKs) built from Dark Energy Camera (DECam) and Visible and Infrared Survey Telescope for Astronomy (VISTA) data. The DES …

Dark Energy Survey year 3 results: covariance modelling and its impact on parameter estimation and quality of fit Open
We describe and test the fiducial covariance matrix model for the combined two-point function analysis of the Dark Energy Survey Year 3 (DES-Y3) data set. Using a variety of new ansatzes for covariance modelling and testing, we validate th…

Phenotypic redshifts with self-organizing maps: A novel method to characterize redshift distributions of source galaxies for weak lensing Open
Wide-field imaging surveys such as the Dark Energy Survey (DES) rely on coarse measurements of spectral energy distributions in a few filters to estimate the redshift distribution of source galaxies. In this regime, sample variance, shot n…
