Galaxy clusters, cosmic chronometers and the Einstein equivalence principle
I. E. C. R. Mendonça, Kamal Bora, R. F. L. Holanda +1
The Einstein equivalence principle in the electromagnetic sector can be violated in modifications of gravity theory generated by a multiplicative coupling of a scalar field to the…
Probing the dark matter density evolution law with large scale structures
Kamal Bora, R. F. L. Holanda, Shantanu Desai
We propose a new method to explore a possible departure from the standard time evolution law for the dark matter density. We looked for a violation of this law by using a deformed…
A test of cosmic distance duality relation using SPT-SZ galaxy clusters, Type Ia supernovae, and cosmic chronometers
Kamal Bora, Shantanu Desai
We carry out a test of the cosmic distance duality relation using a sample of 52 SPT-SZ clusters, along with X-ray measurements from XMM-Newton. To carry out this test, we need an…
A model-independent test of the evolution of gas depletion factor for SPT-SZ and Planck ESZ clusters
Kamal Bora, Shantanu Desai
The gas mass fraction in galaxy clusters has been widely used to determine cosmological parameters. This method assumes that the ratio of the cluster gas mass fraction to the cosmi…
Constraints on variation of fine structure constant from joint SPT-SZ and XMM-Newton observations
Kamal Bora, Shantanu Desai
We search for a variation of the electromagnetic fine structure constant () using a sample of 58 SZ selected clusters in the redshift range () detec…
