STRADAViT: Self-Supervised Domain Adaptation of Vision Transformer Backbones for Radio Astronomy
Andrea DeMarco, Ian Fenech Conti, Hayley Camilleri +2
Next-generation radio astronomy surveys are delivering millions of resolved sources, yet scalable morphology analysis remains difficult across heterogeneous telescopes and imaging…
Euclid preparation: VI. Verifying the Performance of Cosmic Shear Experiments
Euclid Collaboration, P. Paykari, T. D. Kitching +128
Our aim is to quantify the impact of systematic effects on the inference of cosmological parameters from cosmic shear. We present an end-to-end approach that introduces sources of…
A KiDS weak lensing analysis of assembly bias in GAMA galaxy groups
Andrej Dvornik, Marcello Cacciato, Konrad Kuijken +19
We investigate possible signatures of halo assembly bias for spectroscopically selected galaxy groups from the GAMA survey using weak lensing measurements from the spatially overla…
The third data release of the Kilo-Degree Survey and associated data products
J. T. A. de Jong, G. A. Verdoes Kleijn, T. Erben +40
The Kilo-Degree Survey (KiDS) is an ongoing optical wide-field imaging survey with the OmegaCAM camera at the VLT Survey Telescope. It aims to image 1500 square degrees in four fil…
KiDS-450: Testing extensions to the standard cosmological model
Shahab Joudaki, Alexander Mead, Chris Blake +16
We test extensions to the standard cosmological model with weak gravitational lensing tomography using 450 deg of imaging data from the Kilo Degree Survey (KiDS). In these exte…
KiDS-450: Cosmological parameter constraints from tomographic weak gravitational lensing
H. Hildebrandt, M. Viola, C. Heymans +33
We present cosmological parameter constraints from a tomographic weak gravitational lensing analysis of ~450deg of imaging data from the Kilo Degree Survey (KiDS). For a flat $…
Calibration of weak-lensing shear in the Kilo-Degree Survey
Ian Fenech Conti, Ricardo Herbonnet, Henk Hoekstra +3
We describe and test the pipeline used to measure the weak lensing shear signal from the Kilo Degree Survey (KiDS). It includes a novel method of `self-calibration' that partially…
Gravitational Lensing Analysis of the Kilo Degree Survey
Konrad Kuijken, Catherine Heymans, Hendrik Hildebrandt +32
The Kilo-Degree Survey (KiDS) is a multi-band imaging survey designed for cosmological studies from weak lensing and photometric redshifts. It uses the ESO VLT Survey Telescope wit…
GREAT3 results I: systematic errors in shear estimation and the impact of real galaxy morphology
Rachel Mandelbaum, Barnaby Rowe, Robert Armstrong +40
We present first results from the third GRavitational lEnsing Accuracy Testing (GREAT3) challenge, the third in a sequence of challenges for testing methods of inferring weak gravi…
