We present a systematic analysis of the cosmological constraints from the "Pantheon Sample" of 1048 Type Ia Supernovae (SNe Ia) in the redshift range 0.01<z<2.3 compiled by Scolnic et al. (2018). Applying the flux-averaging method for detecting unknown systematic effects, we find that the "Pantheon" sample has been well calibrated and the bias caused by unknown systematic errors has been minimized. We present the estimate of distances measured from SNe Ia and reconstruct the expansion history… Expand
The Next Generation of Cosmological Measurements with Type Ia Supernovae
While Type Ia Supernovae (SNe Ia) are one of the most mature cosmological probes, the next era promises to be extremely exciting in the number of different ways SNe Ia are used to measure variousExpand
Constraints on alternative cosmological models from clustering and redshift-space distortions
In this Thesis I have exploited the most recent observational data from CMB, BAO and growth rate of LSS as well as N-body simulations of modified gravity, to investigate the spatial properties of theExpand
4D Gauss–Bonnet gravity: Cosmological constraints, H0 tension and large scale structure

Cosmological constraints of phantom dark energy models
We address three genuine phantom dark energy models where each of them induces the particular future events known as Big Rip, Little Rip and Little Sibling of the Big Rip. The background models areExpand
Forecasting cosmological bias due to local gravitational redshift
When photons from distant galaxies and stars pass through our neighboring environment, the wavelengths of the photons would be shifted by our local gravitational potential. This local gravitationalExpand
Machine learning improved fits of the sound horizon at the baryon drag epoch

Cosmological constraints on GUP from modified Friedmann equations

In this work we explore signatures of evolution for the dark energy density X(z) = ρ de (z)/ρ de (0) using latest observations on SNIa and H(z). The models consist of parametrizations of the darkExpand
Evaporating primordial black holes as varying dark energy
If light enough primordial black holes account for dark matter, then its density decreases with time as they lose mass via Hawking radiation. We show that this time-dependence of the matter densityExpand
