Extraction of cluster parameters with future Sunyaev-Zel'dovich observations
Nabila Aghanim, Steen H. Hansen, Sergio Pastor +1
The Sunyaev-Zel'dovich (SZ) effect of galaxy clusters is characterized by three parameters: Compton parameter, electron temperature and cluster peculiar velocity. In the present st…
First measurement of cluster temperature using the thermal Sunyaev-Zeldovich effect
Steen H. Hansen, Sergio Pastor, Dmitry V. Semikoz
We discuss a new method of finding the cluster temperatures which is independent of distance and therefore very useful for distant clusters. The hot gas of electrons in clusters of…
Cosmological bounds on neutrino degeneracy improved by flavor oscillations
A. D. Dolgov, S. H. Hansen, S. Pastor +3
We study three-flavor neutrino oscillations in the early universe in the presence of neutrino chemical potentials. We take into account all effects from the background medium, i.e.…
