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

The origin of the Magellanic Stream [PDF]

Monthly Notices of the Royal Astronomical Society, 1994
SHORTENED ABSTRACT: We present numerical investigations designed to critically test models of the origin of the Magellanic Stream. The most developed model is the tidal model which fails to reproduce several of its characteristic properties. We suggest an alternative model for the origin of the Stream which can explain all of its observed features and ...

The Magellanic Stream as a probe of the galactic halo [PDF]

Symposium - International Astronomical Union, 1979
Recent observations of the Magellanic Stream can be used to set limits on a possible hot halo surrounding the Galaxy. The observations are described in detail elsewhere (Mirabel, Cohen & Davies, submitted to Mon. Not. R. astr. Soc.). Briefly, the neutral hydrogen in the northern end of the Magellanic Stream is concentrated in narrow filaments which

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 Distance to the Magellanic Stream: Constraints from Optical Absorption along Stellar Sight Lines [PDF]

The Astrophysical Journal
The Magellanic Stream is a large tail of neutral and ionized gas originating from tidal and hydrodynamical interactions between the Magellanic Clouds as they orbit the Milky Way (MW).

The Magellanic Stream and the Magellanic Cloud System [PDF]

Symposium - International Astronomical Union, 1999
A tidal model has been introduced to the triple system of the Galaxy, Large and Small Magellanic Clouds (the LMC and SMC hereafter) and successfully reproduced the Magellanic Stream (Murai and Fujimoto 1980; Lin and Lynden-Bell 1982; Gardiner et al. 1994; Gardiner and Noguchi 1995; Lin et al. 1995), a narrow band of diffuse atomic hydrogen gas emerging

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 binarity of the Clouds and the formation of the Magellanic Stream [PDF]

Proceedings of the International Astronomical Union, 2008
AbstractThe HST proper motion (PM) measurements of the Clouds have severe implications for their interaction history with the Milky Way (MW) and with each other. The Clouds are likely on their first passage about the MW and the SMC's orbit about the LMC is better described as quasi-periodic rather than circular.

The Small‐Scale Structure of the Magellanic Stream [PDF]

The Astrophysical Journal, 2002
We have mapped two regions at the northern tip of the Magellanic Stream in neutral hydrogen 21-cm emission using the Arecibo telescope. The new data are used to study the morphology and properties of the Stream far away from the Magellanic Clouds, as well as to provide indirect constraints on the properties of the Galactic Halo.
