摘要

在当前的分析中,我们通过分析特定的暗物质模型,研究了银河系晕区内可能存在的广义虫洞模型。我们在最小物质耦合引力的扭转框架内检验了观测数据。利用变分法计算了各向异性物质源下的修正版场方程。为了讨论嵌入式虫洞几何的具体必要特征,我们分析了暗物质晕效应下的能量条件。在本次研究中,我们考虑了两种以龟坐标为单位的嵌入虫洞特定形状函数。此外,我们还根据所涉及的参数值,比较了不同区域范围内的不同虫洞方案。为了检验暗物质晕的影响,我们使用了87星系和银河系特征范围内的观测数据。

Generalized wormhole models within galactic halo region in torsion and matter coupling gravity formalism

In the current analysis, we investigate the possible existence of generalized Wormhole models within the galactic halo region by analyzing specific dark matter models. The observational data is checked in the framework of torsion within minimal matter coupling gravity. By using the variational approach modified versions of the field equations under the anisotropic source of matter are calculated. To discuss the specific necessary characteristics of the embedded wormhole geometry, we have analyzed the energy conditions under the effect of dark matter halos. We consider two embedded wormhole-specific shape functions in terms of the tortoise coordinate for the current study. Further, we compare different wormhole solutions for the different regional ranges depending on the involved parametric values. To check the effect of the dark matter halos, we use the observational data within the signature of the M87 galaxy and the Milky Way galaxy.

期刊介绍: The journal welcomes manuscripts on theoretical models, simulations, and observations of highly energetic astrophysical objects both in our Galaxy and beyond. Among those, black holes at all scales, neutron stars, pulsars and their nebula, binaries, novae and supernovae, their remnants, active galaxies, and clusters are just a few examples. The journal will consider research across the whole electromagnetic spectrum, as well as research using various messengers, such as gravitational waves or neutrinos. Effects of high-energy phenomena on cosmology and star-formation, results from dedicated surveys expanding the knowledge of extreme environments, and astrophysical implications of dark matter are also welcomed topics.
