The Atacama Large Aperture Submillimeter Telescope (AtLAST): enabling large-scale sub-mm science beyond 2030
Claudia Cicone, Tony Mroczkowski, Evanthia Hatziminaoglou +38
AtLAST is designed to be the largest (sub-)mm single-dish astronomical observatory and the first climate-neutral modern research infrastructure. It offers a unique combination of l…
Simulation-based dynamic pointing analysis of AtLAST under wind loading and fast-scan conditions
Aleksej Kiselev, Martin Timpe, Matthias Reichert +2
The Atacama Large Aperture Submillimeter Telescope (AtLAST) is a next-generation 50-m class single-dish facility concept designed for high-throughput, wide-field mapping at millime…
The Atacama Cosmology Telescope: stellar mass growth in massive galaxy clusters from DR5 over the past 7 billion years
Damien C. Ragavan, Unnikrishnan Sureshkumar, Matt Hilton +8
We probe the stellar mass growth in a sample of 568 Sunyaev-Zel'dovich (SZ) selected galaxy clusters with masses greater than and redshifts…
maria goes NIFTy: Gaussian Process-Based Reconstruction and Denoising of Simulated (Sub-)Millimetre Single-Dish Telescope Data
Jonas Würzinger, Joshiwa van Marrewijk, Thomas W. Morris +3
(Sub-)millimetre single-dish telescopes feature faster mapping speeds and access larger spatial scales than their interferometric counterparts. However, atmospheric fluctuations te…
The Atacama Cosmology Telescope: DR6 Sunyaev-Zel'dovich Selected Galaxy Clusters Catalog
HSC Collaboration, M. Aguena, S. Aiola +98
We present the results of a search for galaxy clusters in the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) microwave sky maps covering 16293 square degrees in three frequ…
A high-dynamic-range view of the growth of structure and the warm/hot Universe
Luca Di Mascolo, Tony Mroczkowski, Joshiwa van Marrewijk +23
Baryons heat to temperatures above as they accrete onto massive overdensities -- galaxies, groups, clusters, and filaments -- where they ionize and become o…
