Jens Chluba

Jens Chluba is a Professor of Cosmology at the Jodrell Bank Centre for Astrophysics (JBCA), University of Manchester. His research focuses on extracting cosmological information from the Cosmic Microwave Background (CMB) through spectral distortions, anisotropies, and related phenomena. He is a leading expert in cosmological recombination physics, the Sunyaev-Zeldovich effect, and high-energy processes in the early Universe. Chluba has developed software tools like CosmoRec, CosmoTherm, and SZpack for precise CMB signal computations. His work bridges theoretical astrophysics with observational cosmology, contributing to missions like PIXIE and Simons Observatory.

Research Interests

• CMB Spectral Distortions
• Cosmological Recombination
• Sunyaev-Zeldovich Effect
• Atomic Physics in the Early Universe
• Galaxy Cluster Physics
• Cosmological Parameter Estimation

Recent Contributions

Chluba’s recent work includes studies on relativistic SZ effects in galaxy clusters, spinning dust radiation modeling (SpyDust), and the development of the RHINO antenna for 21cm signal detection. His research also addresses cosmological tensions, such as the Hubble constant discrepancy, through novel theoretical frameworks and observational strategies.

Supervised Students

Chluba has supervised 9 PhD and Master’s theses, including studies on pulsar heating models, hydrodynamic simulations of the Universe, and topological defects in particle physics models.
