Monthly Notices of the Royal Astronomical Society, 521(3), 3384-3404. https://doi.org/10.1093/mnras/stad516

We present the VST ATLAS Quasar Survey, consisting of ∼1229 000 quasar (QSO) candidates with 16 < g < 22.5 over ∼4700 deg2. The catalogue is based on VST ATLAS+NEOWISE imaging surveys and aims to reach a QSO sky density of 130 deg−2 for z < 2.2 and ∼...

VST ATLAS galaxy cluster catalogue I: cluster detection and mass calibration (2023)
Journal Article
Ansarinejad, B., Murphy, D., Shanks, T., & Metcalfe, N. (2023). VST ATLAS galaxy cluster catalogue I: cluster detection and mass calibration. Monthly Notices of the Royal Astronomical Society, 520(1), 1371-1389. https://doi.org/10.1093/mnras/stac3815

Taking advantage of ∼4700 deg2 optical coverage of the Southern sky offered by the VST ATLAS survey, we construct a new catalogue of photometrically selected galaxy groups and clusters using the ORCA cluster detection algorithm. The catalogue contain... Read More about VST ATLAS galaxy cluster catalogue I: cluster detection and mass calibration.
