Model independent constraints on transition redshift
J. F. Jesus, R. F. L. Holanda, S. H. Pereira
This paper aims to put constraints on the transition redshift , which determines the onset of cosmic acceleration, in cosmological-model independent frameworks. In order to pe…
Is the non-isothermal double -model incompatible with no time evolution of galaxy cluster gas mass fraction ?
R. F. L. Holanda
In this paper, we propose a new method to obtain the depletion factor , the ratio by which the measured baryon fraction in galaxy clusters is depleted with respect to the uni…
Constraints on the cosmic distance duality relation with simulated data of gravitational waves from the Einstein Telescope
Tao Yang, R. F. L. Holanda, Bin Hu
The cosmic distance duality relation (CDDR) has been test through several astronomical observations in the last years. This relation establishes a simple equation relating the angu…
X-ray surface brightness observations of galaxy clusters, cosmic opacity and the limits on the matter density parameter
R. F. L. Holanda, Kamilla V. R. A. Silva, V. C. Busti
In this work, we use two gas mass fraction samples of galaxy clusters obtained from their X-ray surface brightness observations jointly with recent data in a flat CDM fra…
Cosmological constraints on the gas depletion factor in galaxy clusters
R. F. L. Holanda, V. C. Busti, J. E. Gonzalez +2
The evolution of the X-ray emitting gas mass fraction () in massive galaxy clusters can be used as an independent cosmological tool to probe the expansion history of the U…
Constraints on a possible evolution of mass density power-law index in strong gravitational lensing from cosmological data
R. F. L. Holanda, S. H. Pereira, Deepak Jain
In this work, by using strong gravitational lensing (SGL) observations along with Type Ia Supernovae (Union2.1) and gamma ray burst data (GRBs), we propose a new method to study a…
