Magellanic Stream in MOND
The dynamics of Magellanic Stream (MS) as a series of clouds extended from the Magellanic Clouds (MCs) to the south Galactic pole is affected by the distribution and the amount of matter in the Milky Way (MW). We calculate the gravitational effect of the Galactic disk on MS in the MOdified Newtonian Dynamics (MOND) frame work and compare with the observations of the radial velocity. Here we con...
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولOn the formation of the Magellanic Stream
We use high resolution N-Body/SPH simulations to study the hydrodynamical and gravitational interaction between the Large Magellanic Cloud and the Milky Way. We model the dark and hot extended halo components as well as the stellar/gaseous disks of the two galaxies. Tidal forces distort the LMC’s disk, forcing a bar and creating a diffuse stellar halo and a strong warp, although very few stars ...
متن کاملThe Origin of the Magellanic Stream
Recent measurements of the proper motion of the Large Magellanic Cloud (LMC) show it to be moving in a nearly circular orbit around the Milky Way and to be leading the Magellanic Stream which stretches in a well-confined arc 100 behind it. We present numerical investigations designed to critically test models of the origin of the Magellanic Stream. The most developed model is the tidal model wh...
متن کاملN-body Simulations of the Magellanic Stream
A suite of high-resolution N-body simulations of the Magellanic Clouds – Milky Way system are presented and compared directly with newly available data from the H i Parkes All-Sky Survey (HIPASS). We show that the interaction between Small and Large Magellanic Clouds results in both a spatial and kinematical bifurcation of both the Stream and the Leading Arm. The spatial bifurcation of the Stre...
