Variation of the subhalo abundance in dark matter halos
We analyzed the statistics of subhalo abundance of galaxy-sized and giantgalaxy-sized halos formed in a high-resolution cosmological simulation of a 46.5Mpc cube with the uniform mass resolution of 10M⊙. We analyzed all halos with mass more than 1.5 × 10M⊙ formed in this simulation box. The total number of halos was 125. We found that the subhalo abundance, measured by the number of subhalos wi...
متن کاملCluster abundance in fðRÞ gravity models
As one of the most powerful probes of cosmological structure formation, the abundance of massive galaxy clusters is a sensitive probe of modifications to gravity on cosmological scales. In this paper, we present results from N-body simulations of a general class of fðRÞ models, which self-consistently solve the nonlinear field equation for the enhanced forces. Within this class we vary the ampl...
متن کاملEnvironmental effect on the subhalo abundance — a solution to the missing dwarf problem
Recent high-resolution simulations of the formation of dark-matter halos have shown that the distribution of subhalos is scale-free, in the sense that if scaled by the velocity dispersion of the parent halo, the subhalo velocity distribution function of galaxy-sized and cluster-sized halos are identical. For clustersized halos, simulation results agreed well with observations. Simulations, howe...
متن کاملStream-subhalo interactions in the Aquarius simulations
Aims. We perform the first self-consistent measurement of the rate of interactions between stellar tidal streams created by disrupting satellites and dark subhalos in a cosmological simulation of a Milky-Way-mass galaxy. Methods. Using a retagged version of the Aquarius A dark-matter-only simulation, we selected 18 streams of tagged star particles that appear thin at the present day and followe...
متن کاملfault location in power distribution networks using matching algorithm
چکیده رساله/پایان نامه : تاکنون روشهای متعددی در ارتباط با مکان یابی خطا در شبکه انتقال ارائه شده است. استفاده مستقیم از این روشها در شبکه توزیع به دلایلی همچون وجود انشعابهای متعدد، غیر یکنواختی فیدرها (خطوط کابلی، خطوط هوایی، سطح مقطع متفاوت انشعاب ها و تنه اصلی فیدر)، نامتعادلی (عدم جابجا شدگی خطوط، بارهای تکفاز و سه فاز)، ثابت نبودن بار و اندازه گیری مقادیر ولتاژ و جریان فقط در ابتدای...
