We use luminous red galaxies selected from the imaging surveys that are being used for targeting by Dark Energy Spectroscopic Instrument (DESI) in combination with CMB lensing maps Planck collaboration to probe amplitude of large-scale structure over $0.4\le z\le 1$. Our galaxy sample, an angular number density approximately $500\,\mathrm{deg}^{-2}$ 18,000 sq.deg., is divided into 4 tomographic...

Abstract We study the semileptonic $$B\rightarrow {\textbf{B}{\bar{\mathbf{B'}}}}L{\bar{L}}'$$ B → ′ ¯ L decays with $$\textbf{B}{\bar{\textbf{B}}'}$$ ( $$L{\bar{L}}'$$ ) ...

We study a power-law $F(R)$ gravity with an early dark energy term, that can describe both the early-time and late-time acceleration of Universe. confront this scenario recent observational data including Pantheon Type Ia supernovae, measurements Hubble parameter $H(z)$ (Cosmic Chronometers), from Baryon Acoustic Oscillations standard rulers Cosmic Microwave Background (CMB) radiation. The mode...

We present constraints on the tensor-to-scalar ratio $r$ using a combination of BICEP/Keck 2018 (BK18) and Planck PR4 data allowing us to fit for consistently with six parameters $\mathrm{\ensuremath{\Lambda}}\mathrm{CDM}$ model. discuss sensitivity uncertainties in as defined by data. In particular, we are able derive constraint reionization optical depth $\ensuremath{\tau}$ thus propagate its...

The first general Zagreb index is defined as $M_1^lambda(G)=sum_{vin V(G)}d_{G}(v)^lambda$. The case $lambda=3$, is called F-index. Similarly, reformulated first general Zagreb index is defined in terms of edge-drees as $EM_1^lambda(G)=sum_{ein E(G)}d_{G}(e)^lambda$ and the reformulated F-index is $RF(G)=sum_{ein E(G)}d_{G}(e)^3$. In this paper, we compute the reformulated F-index for some grap...

 Let $P(lambda)$ be an $n$-square complex matrix polynomial, and $1 leq k leq n$ be a positive integer. In this paper, some algebraic and geometrical properties of the $k$-numerical range of $P(lambda)$ are investigated. In particular, the relationship between the $k$-numerical range of $P(lambda)$ and the $k$-numerical range of its companion linearization is stated. Moreover, the $k$-numerical...

A characteriation of continuity of the $p$-$Lambda$-variation function is given and the Helly's selection principle for $Lambda BV^{(p)}$ functions is established. A characterization of the inclusion of Waterman-Shiba classes into classes of functions with given integral modulus of continuity is given. A useful estimate on modulus of variation of functions of class $Lambda BV^{(p)}$ is found.
