Mitigating the impact of the CIB on galaxy cluster SZ detection with spectrally constrained matched filters
Íñigo Zubeldia, Jens Chluba, Richard Battye
Galaxy clusters detected through the thermal Sunyaev-Zeldovich (tSZ) effect are a powerful cosmological probe from which constraints on cosmological parameters such as $Ω_{\mathrm{…
Towards Optimal Foreground Mitigation Strategies for Interferometric HI Intensity Mapping in the Low-Redshift Universe
Zhaoting Chen, Laura Wolz, Richard Battye
We conduct the first case study towards developing optimal foreground mitigation strategies for neutral hydrogen (HI) intensity mapping using radio interferometers at low redshifts…
Galaxy cluster SZ detection with unbiased noise estimation: an iterative approach
Íñigo Zubeldia, Aditya Rotti, Jens Chluba +1
Multi-frequency matched filters (MMFs) are routinely used to detect galaxy clusters from CMB data through the thermal Sunyaev-Zeldovich (tSZ) effect, leading to cluster catalogues…
Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies
Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200
In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological…
