Number Counts and Dynamical Vacuum Cosmologies
N. Chandrachani Devi, H. A. Borges, S. Carneiro +1
We study non-linear structure formation in an interacting model of the dark sector of the Universe in which the dark energy density decays linearly with the Hubble parameter, $ρ_Λ…
Geodesic Motion in Schwarzschild Spacetime Surrounded by Quintessence
Rashmi Uniyal, N. Chandrachani Devi, Hemwati Nandan +1
We study the time-like geodesic congruences, in the space-time geometry of a Schwarzschild black hole surrounded by quintessence. The nature of effective potential along with the s…
J-PAS: The Javalambre-Physics of the Accelerated Universe Astrophysical Survey
N. Benitez, R. Dupke, M. Moles +149
The Javalambre-Physics of the Accelerated Universe Astrophysical Survey (J-PAS) is a narrow band, very wide field Cosmological Survey to be carried out from the Javalambre Observat…
Constraining thawing and freezing models with cluster number counts
N. Chandrachani Devi, J. E. Gonzalez, J. S. Alcaniz
Measurements of the cluster abundance as a function of mass and redshift provide an important cosmological test that probe not only the expansion rate but also the growth of pertur…
