Cosmological analysis using Panstarrs data: Hubble constant and direction dependence
نویسندگان
چکیده
Hubble tension is among the most crucial unresolved issues in modern cosmology. In addition, search for preferred direction has also been explored last two decades. Different measurements of constant provide significantly different values, and this known as tension. The cosmological principle assumes that universe homogeneous isotropic; however, deviations from isotropy have often claimed. We apply Bayesian tools Extreme Value theory dependent statistic to address above issues. These techniques applied Panstarrs1 type Ia supernovae data. Our analysis does not reject However, our value smaller than SHoES program agrees with CCHP value. theory-based indicates data show directional dependence. As a byproduct technique, we errors are non-Gaussian nature.

The Hubble Constant and Dark Energy from Cosmological Distance Measures
We study how the determination of the Hubble constant from cosmological distance measures is affected by models of dark energy and vice versa. For this purpose, constraints on the Hubble constant and dark energy are investigated using the cosmological observations of cosmic microwave background, baryon acoustic oscillations and type Ia suprenovae. When one investigates dark energy, the Hubble c...
متن کاملOnline Inertia Constant and Thévenin Equivalent Estimation Using PMU Data
In this paper a new algorithm based on phasor measurements for estimating the Thévenin Equivalent (TE) and system inertia constant is proposed. The method estimates the network TE seen from a generator terminal and equivalent system inertia constant by means of phasor data that is available at Phasor Data Concentrator (PDC) center. It is shown that the parameters of the TE could be estimated at...
متن کاملConditional Dependence in Longitudinal Data Analysis
Mixed models are widely used to analyze longitudinal data. In their conventional formulation as linear mixed models (LMMs) and generalized LMMs (GLMMs), a commonly indispensable assumption in settings involving longitudinal non-Gaussian data is that the longitudinal observations from subjects are conditionally independent, given subject-specific random effects. Although conventional Gaussian...
متن کاملCosmological Parameters and Hyper-Parameters: The Hubble Constant from Boomerang and Maxima
We generalise the procedure for joint estimation of cosmological parameters to allow freedom in the relative weights of various probes. This is done by including in the joint Likelihood function a set of ‘Hyper-Parameters’, which are dealt with using Bayesian considerations. The resulting algorithm is simple to implement. We illustrate the method by estimating the Hubble constant H0 from the re...
متن کاملCepheid metallicity and Hubble constant
This study combines data from a set of seven Cepheid-calibrated galaxies in Virgo, Leo I and Fornax and four supernovæ with known metallicities, including metallicity corrections to the Cepheid distances, in order to determine a consistent mean value for the Hubble constant. We derive Virgo and Coma distances over different paths, starting from the metallicity corrected Cepheid distances of Vir...
