چکیده

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 are unbound from the LMC. Ram-pressure from a low density ionised halo is then sufficient to remove 1.4 × 108M⊙ of gas from the LMC’s disk forming a great circle trailing stream around the Galaxy.

The detection of an older population in the Magellanic Bridge

Context. The Magellanic system comprises the Large Magellanic Cloud (LMC), the Small Magellanic Cloud (SMC), and the less frequently observed Magellanic Bridge and Magellanic Stream. The Bridge is traced by neutral gas and has an observed stellar component, while the Stream consists of gas only, with no observed stellar counterpart to date. Aims. This study uses catalogues created in the direct...

Modeling a high velocity LMC . The formation of the Magellanic Stream

I use high resolution N-body/SPH simulations to model the new proper motion of the Large Magellanic Cloud (LMC) within the Milky Way (MW) halo and investigate the effects of gravitational and hydrodynamical forces on the formation of the Magellanic Stream (MS). Both the LMC and the MW are fully self consistent galaxy models embedded in extended cuspy ΛCDM dark matter halos. I find that ram-pres...

FORMATION OF GLOBULAR STRUCTURES IN ALUMINUM A356 ALLOY BY NARROWMELT STREAM (NMS) TECHNIQUE

Abstract: structures in alloys. This method is based on pouring the melt through a small sized nozzle into a mould located at acertain height under the crucible. This simple method generates globular structures without using equipments such asimpellers, electromagnetic stirrers, ultrasonic probes and cooling slopes. Therefore it is cost effective. In the presentstudy, the effect of casting size...

The aim of this work is to model the formation of the Magellanic Stream via the resulting tidal gravitational field from the merger of the Milky Way with the Large and Small Magellanic Clouds (LMC and SMC, respectively). Two popular, yet competing, scenarios for the Stream’s formation are based upon tidal disruption (Lin & Lynden-Bell 1977; Gardiner & Noguchi, 1996) or ram-pressure stripping (M...

N-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...
