Discovery of a Radio Relic in the Massive Merging Cluster SPT-CL 2023-5535 from the ASKAP-EMU PILOT SURVEY
Kim HyeongHan, M. James Jee, Lawrence Rudnick +11
The ASKAP-EMU survey is a deep wide-field radio continuum survey designed to cover the entire southern sky and a significant fraction of the northern sky up to . Here,…
Baryonic feedback measurement from KV450 cosmic shear analysis
Mijin Yoon, M. James Jee
While baryonic feedback is one of the most important astrophysical systematics that we need to address in order to achieve precision cosmology, few weak lensing studies have direct…
Toward Solving the Puzzle: Dissecting the Complex Merger A521 with Multi-wavelength Data
Mijin Yoon, Wonki Lee, M. James Jee +3
A521 has been a subject of extensive panchromatic studies from X-ray to radio. The cluster possesses a number of remarkable features including a bright radio relic with a steep spe…
Minimising the impact of scale-dependent galaxy bias on the joint cosmological analysis of large scale structures
Marika Asgari, Indiarose Friswell, Mijin Yoon +5
We present a mitigation strategy to reduce the impact of non-linear galaxy bias on the joint `pt' cosmological analysis of weak lensing and galaxy surveys. The -sta…
Constraints on Cosmology and Baryonic Feedback with the Deep Lens Survey Using Galaxy-Galaxy and Galaxy-Mass Power Spectra
Mijin Yoon, M. James Jee, J. Anthony Tyson +3
We present cosmological parameter measurements from the Deep Lens Survey (DLS) using galaxy-mass and galaxy-galaxy power spectra in the multipole range . We measu…
