Our current understanding of the Universe is established through pristine measurements structure in cosmic microwave background (CMB) and distribution shapes galaxies tracing large scale (LSS) Universe. One key ingredient that underlies cosmological observables field sources observed assumed to be initially Gaussian with high precision. Nevertheless, a minimal deviation from Gaussianityis perhaps most robust theoretical prediction models explain Universe; itis necessarily present even...
We present a novel mathematical formalism that allows to easily compute the expected kinetic Sunyaev Zeldovich (kSZ) signal in intensity and polarization due an anisotropic primordial Cosmic Microwave Background (CMB). derive distortions direction of non-moving galaxy clusters then we generalize our calculations for non-zero peculiar velocity. show that, moving clusters, low CMB multipoles impose spectral with different frequency dependences. The primarily probes quadrupole moment CMB,...
Antinociceptive activity of methanolic extract aerial parts Epilobium hirsutum (EH) was determined in the Hot plate and writhing tests mice. Nearly all extracts showed a dose dependent marked analgesic mice thermal chemical models analgesia when compared to control. Methanol at 500 mg kg(-1) higher (97.7% inhibition) than diclofenac 50 i.p., (77.8%, p<0.05) morphine 5 i.p.

We present a general framework for the accurate spectral modeling of low multipoles cosmic microwave background (CMB) as observed in boosted frame. In particular, we demonstrate how measurements can be used to separate motion-induced dipole CMB from possible intrinsic component. moving frame, leakage an moment into monopole and quadrupole induces distortions with distinct frequency functions that, respectively, peak at 337 276 GHz. The also geometrical distortion spatial morphology this...
We introduce a new estimator for the mean pairwise velocities of galaxy clusters, which is based on measurement clusters' $\textit{transverse}$ velocity components. The Rees-Sciama (RS) effect offers an opportunity to measure transverse peculiar through its distinct dipolar signature around halo centers in Cosmic Microwave Background (CMB) temperature map. exploit this structure extract magnitude and direction vectors from CMB maps simulated with expected characteristics future surveys like...
In the frame of Solar System, Doppler and aberration effects cause distortions in form mode couplings cosmic microwave background (CMB) temperature polarization power spectra hence impose biases on statistics derived by moving observer. We explore several aspects such pay close attention to their CMB which previously have not been examined detail. A potentially important bias that we introduce here is $\textit{boost variance}$---an additional term variance, induced observer's motion....
We introduce a frequency-dependent Doppler and aberration transformation kernel for the harmonic multipoles of general cosmological observable with spin weight $s$, $d$ arbitrary frequency spectrum. In context cosmic microwave background (CMB) studies, formalism allows to correct motion-induced effects on individual maps different masks. It also permits deboost radiations non-blackbody spectra, like extragalactic foregrounds CMB spectra primordial spectral distortions. The can be used E B...
In this work we examine the impact of our motion with respect to CMB rest frame on statistics maps by examining one-, two-, three- and four- point simulated Sunyaev-Zeldovich (SZ) effects. We validate boosting codes comparing their outcomes for temperature polarization power spectra up $\ell \simeq 6000$. derive a new analytical formula computation boosted spectrum signal generic frequency dependence. As an example show how increases correction intensity measurements $\sim 30\%$ at 150 GHz....
