Constraining f(R) models with cosmic chronometers and the HII galaxy Hubble diagram
Joseph Sultana, Manoj K. Yennapureddy, Fulvio Melia +1
We consider several well-known f(R) cosmological models and constrain their parameters, namely the deviation parameter b and the cosmological parameters Ω_m and h. We first obtain…
Structure formation and the matter power-spectrum in the R_h=ct universe
Manoj K. Yennapureddy, Fulvio Melia
Inflation drives quantum fluctuations beyond the Hubble horizon, freezing them out before the small-scale modes re-enter during the radiation dominated epoch, and subsequently deca…
A comparison of the R_h=ct and LCDM cosmologies based on the observed halo mass function
Manoj K. Yennapureddy, Fulvio Melia
The growth of structure probes the re-ionization history and quasar abundance in the Universe, constituting an important probe of the cosmological predictions. Halos are not direct…
The Maximum Angular-Diameter Distance in Cosmology
Fulvio Melia, Manoj K. Yennapureddy
Unlike other observational signatures in cosmology, the angular-diameter distance d_A(z) uniquely reaches a maximum (at z_max) and then shrinks to zero towards the big bang. The lo…
A Cosmological Solution to the Impossibly Early Galaxy Problem
Manoj K. Yennapureddy, Fulvio Melia
To understand the formation and evolution of galaxies at redshifts z < 10, one must invariably introduce specific models (e.g., for the star formation) in order to fully interpret…
Cosmological Tests With Strong Gravitational Lenses using Gaussian Processes
Manoj K. Yennapureddy, Fulvio Melia
Strong gravitational lenses provide source/lens distance ratios D_obs useful in cosmological tests. Previously, a catalog of 69 such systems was used in a one-on-one comparison bet…
Model Selection Using Cosmic Chronometers with Gaussian Processes
Fulvio Melia, Manoj K. Yennapureddy
The use of Gaussian Processes with a measurement of the cosmic expansion rate based solely on the observation of cosmic chronometers provides a completely cosmology-independent rec…
Reconstruction of the HII Galaxy Hubble Diagram using Gaussian Processes
Manoj K. Yennapureddy, Fulvio Melia
The Hubble diagram constructed using HII galaxies (HIIGx) and Giant extragalactic HII regions (GEHR) as standard candles already extends beyond the current reach of Type Ia SNe. A…
