Halo Concentrations and the Fundamental Plane of Galaxy Clusters
Yutaka Fujita, Megan Donahue, Stefano Ettori +6
According to the standard cold dark matter (CDM) cosmology, the structure of dark halos including those of galaxy clusters reflects their mass accretion history. Older clusters ten…
Discovery of Kolmogorov-like Magnetic Energy Spectrum in Tycho's Supernova Remnant by Two-point Correlations of Synchrotron Intensity
Jiro Shimoda, Takuya Akahori, A. Lazarian +2
The spectral slope of the magnetic energy in supernova remnants (SNRs) can be obtained by analysis of spatial two-point correlation functions of synchrotron intensities. This metho…
A New Interpretation of the Mass-Temperature Relation and Mass Calibration of Galaxy Clusters Based on the Fundamental Plane
Yutaka Fujita, Keiichi Umetsu, Stefano Ettori +3
Observations and numerical simulations have shown that the relation between the mass scaled with the critical density of the universe and the X-ray temperature of galaxy clusters i…
Discovery of a new fundamental plane dictating galaxy cluster evolution from gravitational lensing
Yutaka Fujita, Keiichi Umetsu, Elena Rasia +5
In cold dark matter (CDM) cosmology, objects in the Universe have grown under the effect of gravity of dark matter. The intracluster gas in a galaxy cluster was heated when the dar…
