The Spine of the Cosmic Web

چکیده
We present a new concept, the Spine of the Cosmic Web, for the topological analysis of the Cosmic Web and the identification of its filaments and walls. Based on the watershed segmentation of the cosmic density field, the method invokes the local properties of the regions adjacent to the critical points, which define its separatrices. Our method allows their classification into walls and the spine of filaments and clusters. Tests on a heuristic Voronoi model yielded outstanding results.

Time Delays in Cosmic Ray Propagation
Cosmic Rays (CR) travel at speeds essentially indistinguishable from the speed of light. However whilst travelling through magnetic fields, both regular and turbulent, they are delayed behind the light since they are usually charged particles and their paths are not linear. Those delays can be so long that they are an impediment to correctly identifying sources which may be variable in time. Fu...
متن کاملCosmic Walls and Filaments Formation in Modied Chaplygin Gas Cosmology
We want to study the perturbation growth of an initial seed of an ellipsoidal shape in Top-Hat collapse model of the structure formation in the Modied Chaplygin gas cosmology. Considering reasonable values of the constants and the parameters of the model under study, we can show that a very small deviation from spherical symmetry (ellipsoidal geometry) in the initial seed leads to a nal highly ...
متن کاملGeomagnetic Field Eect over Azimuth Anisotropy of Cosmic Rays via Study of Primary Particles
Geomagnetic field is a one of the candidates for creation of anisotropy in azimuth distribution of extensive air showers over the entered cosmic rays to the atmosphere. Here we present the question: Is there any azimuth anisotropy flux in the upper level of the atmosphere due to the geomagnetic field over the entered cosmic-rays? The obtained answer is: yes. This investigation showed an agreeme...
متن کاملA study on the lateral distribution of Cherenkov light in extensive air showers
The dependence of the lateral distribution of Cherenkov light in simulated extensive air showers to the energy and the mass of the primary cosmic rays has been studied. It has been shown that a previous claim about mass independent proportionality of shower energy to the total Cherenkov photon number is not valid in energies below EEAS ~ 1014 eV. We have found that the core distance of the so c...
متن کاملsystematic review of the characteristics of ultrasound measurements in the evaluation of spinal curvatures in scoliosis patients
Abstract Aims: Scoliosis is one of the secondary complications in amputation veterans, which requires periodic evaluations. The gold standard for evaluating the spine is radiography, which has caused many concerns due to the very high doses of X-ray radiation. For this reason, therapists are finding for an alternative method for this tool, so ultrasound is a non-invasive tool with different me...
