Thermal Sunyaev-Zel'dovich cross-correlations with unWISE galaxies: disentangling radio contamination, dust properties, and electron pressure
Guandi Zhao, Alex Krolewski, Niayesh Afshordi
Cross-correlations between the thermal Sunyaev-Zel'dovich (tSZ) effect and galaxy surveys provide a sensitive probe of hot gas in low-mass halos, but on the angular scales of great…
Characterizing robotic positioners under the influence of changing gravity vectors for future spectroscopic surveys
Johannes Wüthrich, Guandi Zhao, Banan Yamani +5
Future (Stage V) spectroscopic surveys intend to accurately map billions of galaxies. To accomplish this goal, these surveys will employ highly multiplexed focal planes composed of…
Characterisation of the Bedretto Underground Site for Fundamental Physics Experiments
Björn Penning, Nicolas Angelides, Laura Baudis +33
Underground laboratories provide the ultra-low background and low-vibration environments essential for rare-event searches, gravitational-wave detection, and quantum-sensing techno…
Halo spin and orientation in Interacting Dark Matter Dark Energy Cosmology
Guandi Zhao, Jiajun Zhang, Peng Wang +1
In recent years, the interaction between dark matter (DM) and dark energy (DE) has become a topic of interest in cosmology. Interacting dark matter-dark energy (IDE) models have a…
