Atmospheric pressure and molecular cloud formation in early-type galaxies
Iurii Babyk, Brian McNamara, Paul Nulsen +3
A strong correlation between atmospheric pressure and molecular gas mass is found in central cluster galaxies and early-type galaxies. This trend and a similar trend with atmospher…
New constraints on light Axion-Like Particles using Chandra Transmission Grating Spectroscopy of the powerful cluster-hosted quasar H1821+643
Júlia Sisk Reynés, James H. Matthews, Christopher S. Reynolds +3
Axion-Like Particles (ALPs) are predicted by several Beyond the Standard Model theories, in particular, string theory. In the presence of an external magnetic field perpendicular t…
Constraining Merging Galaxy Clusters with X-ray and Lensing Simulations and Observations: The case of Abell 2146
Urmila Chadayammuri, John ZuHone, Paul Nulsen +5
Galaxy cluster mergers are a powerful laboratory for testing cosmological and astrophysical models. However, interpreting individual merging clusters depends crucially on their mer…
Suppressed cooling and turbulent heating in the core of X-ray luminous clusters RXCJ1504.1-0248 and Abell 1664
Haonan Liu, Andrew C. Fabian, Ciro Pinto +3
We present the analysis of XMM-Newton observations of two X-ray luminous cool core clusters, RXCJ1504.1-0248 and Abell 1664. The Reflection Grating Spectrometer reveals a radiative…
