Untangling Magellanic Streams

The Open Journal of Astrophysics
The Magellanic Stream (MS) is known to contain multiple HI strands and corresponding stellar populations are being discovered. Combining a sample of 17 stars from the H3 (“Hectochelle in the Halo at High Resolution”) survey with 891 stars drawn from the

N-body simulations of the Magellanic Stream [PDF]

Mon.Not.Roy.Astron.Soc.371:108-120,2006, 2005
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 HI 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 ...

N-body Simulations of the Small Magellanic Cloud and the Magellanic Stream [PDF]

Monthly Notices of the Royal Astronomical Society, 1995
An extensive set of N-body simulations has been carried out on the gravitational interaction of the Small Magellanic Cloud (SMC) with the Galaxy and the Large Magellanic Cloud (LMC). The SMC is assumed to have been a barred galaxy with a disc-to-halo mass ratio of unity before interaction and modelled by a large number of self-gravitating particles ...

Cold HI ejected into the Magellanic Stream [PDF]

, 2020
We report the direct detection of cold HI gas in a cloud ejected from the Small Magellanic Cloud (SMC) towards the Magellanic Stream. The cloud is part of a fragmented shell of HI gas on the outskirts of the SMC. This is the second direct detection of cold HI associated with the Magellanic Stream using absorption.

A Search for 3-mm Molecular Absorption Line Transitions in the Magellanic Stream [PDF]

Publications Astronomical Society of Australia
The Magellanic Stream (MS), a tail of diffuse gas formed from tidal and ram pressure interactions between the Small and Large Magellanic Clouds (SMC and LMC) and the Halo of the Milky Way, is primarily composed of neutral atomic hydrogen (HI).

THE MAGELLANIC STREAM AND DEBRIS CLOUDS [PDF]

The Astrophysical Journal, 2014
We present a study of the discrete clouds and filaments in the Magellanic Stream using a new high-resolution survey of neutral hydrogen (H i) conducted with the H75 array of the Australia Telescope Compact Array, complemented by single-dish data from the

Discovery of a Split Stellar Stream In the Periphery of the Small Magellanic Cloud [PDF]

arXiv, 2023
I report the discovery of a stellar stream (Sutlej) using Gaia DR3 proper motions and XP metallicities located ~15 degrees north of the Small Magellanic Cloud (SMC). The stream is composed of two parallel linear components ("branches") approximately ~8 x 0.6 degrees in size and separated by 2.5 degrees.

Revealing the Ionization Properties of the Magellanic Stream using Optical Emission [PDF]

, 2017
The Magellanic Stream, a gaseous tail that trails behind the Magellanic Clouds, could replenish the Milky Way with a tremendous amount of gas if it reaches the Galactic disk before it evaporates into the halo. To determine how the Magellanic Stream's properties change along its length, we have conducted an observational study of the H-alpha emission ...

The COS/UVES Absorption Survey of the Magellanic Stream. III: Ionization, Total Mass, and Inflow Rate onto the Milky Way [PDF]

, 2014
Dynamic interactions between the two Magellanic Clouds have flung large quantities of gas into the halo of the Milky Way, creating the Magellanic Stream, the Magellanic Bridge, and the Leading Arm (collectively referred to as the Magellanic System). In this third paper of a series studying the Magellanic gas in absorption, we analyze the gas ionization

A Primeval Magellanic Stream and Others [PDF]

The Astrophysical Journal, 2013
The Magellanic Stream might have grown out of tidal interactions at high redshift, when the young galaxies were close together, rather than from later interactions among the Magellanic Clouds and Milky Way. This is illustrated in solutions for the orbits of Local Group galaxies under the cosmological condition of growing peculiar velocities at high ...
