We calculate the intensity and angular power spectrum of cosmological background synchrotron emission from cold dark matter annihilations into electron–positron pairs. compare this with anisotropy astrophysical radio backgrounds, such as those normal galaxies, galaxies galaxy cluster accretion shocks, cosmic microwave Galactic foregrounds. Under modest assumptions for clustering we find that around 2 GHz average fluctuations at sub-degree scales allow us to probe masses GeV annihilation...
High energy electrons and positrons from decaying dark matter can produce a significant flux of gamma rays by inverse Compton off low photons in the interstellar radiation field. This possibility is inevitably related with interpretation observed PAMELA FERMI excesses. The aim this paper providing simple universal method to constraint models which their decay using Fermi LAT gamma-ray observations range between 0.5 GeV 300 GeV. We provide set response functions that, once convolved specific...
If dark matter decays into electrons and positrons, it can affect Galactic radio emissions the local cosmic ray fluxes. We propose a new, more general analysis of constraints on matter. The be obtained for any decaying model by convolving specific decay spectrum with response function. derive this function from full-sky surveys at 408 MHz, 1.42 GHz 23 GHz, as well positron flux recently reported PAMELA. discuss influence astrophysical uncertainties function, such propagation profiles...
High energy electrons and positrons from annihilating dark matter can imprint unique angular anisotropies on the diffuse gamma-ray flux by inverse Compton scattering off interstellar radiation field. We develop a numerical tool to compute emission such produced in smooth host halo substructure halos with masses down 10^(-6)M_sun. show that power spectrum is exponentially suppressed below an scale determined diffusion length of positrons. also find total shape depends sensitively spatial...
This study employs a novel approach for reconstructing the thermal Sunyaev-Zeldovich (tSZ) effect power spectrum from Planck data using Analytical Blind Separation (ABS) method. The ABS method improves recovery of weak signals, by applying eigenmode exclusion low signal-to-noise ratio regimes and introducing shift parameter to stabilize calculations. Validation through simulated demonstrates robustness in tSZ spectrum, even under challenging conditions. In analysis PR3 full-mission data,...
We study Crofton’s formula in the Lorentzian AdS 3 and find that area of a generic spacelike two-dimensional surface is given by flux geodesics. The “complexity[Formula: see text]=[Formula: text]volume” conjecture then implies new holographic representation complexity terms number Finally, we explore possible explanation this result from standpoint information theory.
If dark matter decays or annihilates into electrons and positrons, it can affect radiation cosmic-ray backgrounds. We review a novel, more general analysis of constraints on decaying models, by introducing the response functions based current radio, gamma-ray positron observations. Constraints be simply obtained requiring convolution with actual decay spectrum positrons smaller than product lifetime in 10^{26}s mass 100GeV. The just depend astrophysical inputs such as propagation model, but...

<p>The Qinling Orogenic Belt (QOB) has been well documented that it was formed by multiple steps of convergence and subsequent collision between the North China Block (NCB) South (SCB) during Paleozoic Late Triassic. Following in Triassic, whole QOB evolved into an intracontinental orogeny. Large-scale N-S compressional thrusting deformation tectonics along previous major boundary faults were developed. Meanwhile, several extension-related also developed or slightly later than...
