The Formation of Magellanic System and the total mass of Large Magellanic Cloud [PDF]
arXiv, 2023 The Magellanic Stream is unique to sample the MW potential from ~50 kpc to 300 kpc, and is also unique in constraining the LMC mass, an increasingly important question for the Local Group/Milky Way modeling. Here we compare strengths and weaknesses of the two types of models (tidal and ram-pressure) of the Magellanic Stream formation.

Constraining the orbital history of the Magellanic Clouds: a new bound scenario suggested by the tidal origin of the Magellanic Stream [PDF]
, 2011 Bound orbits have traditionally been assigned to the Large and Small Magellanic Clouds (LMC and SMC, respectively) in order to provide a formation scenario for the Magellanic Stream (MS) and its Leading Arm (LA), two prominent neutral hydrogen (HI ...

Ecology and Evolution, Volume 14, Issue 2, February 2024.Some white‐tailed deer populations are migratory in locations with severe and chronic seasonal resource limitations, but biological justification for such behaviors is lacking at lower latitudes. We document migratory behavior termed the "mobile" movement strategy in 33% of adult male deer in a low‐latitude system void of such environmental pressures ...

Advances in Astronomy, Volume 2010, Issue 1, 2010., 2010 In this tutorial paper we summarize how the star formation (SF) history of a galactic region can be derived from the colour‐magnitude diagram (CMD) of its resolved stars. The procedures to build synthetic CMDs and to exploit them to derive the SF histories (SFHs) are described, as well as the corresponding uncertainties.

The Truncated Circumgalactic Medium of the Large Magellanic Cloud
The Astrophysical Journal LettersThe Large Magellanic Cloud (LMC) is the nearest massive galaxy to the Milky Way (MW). Its circumgalactic medium (CGM) is complex and multiphase, containing both stripped H i structures like the Magellanic Stream and Bridge and a diffuse warm corona seen ...

The Relevance of Dynamical Friction for the MW/LMC/SMC Triple System
UniverseSimulations of structure formation in the standard cold dark matter cosmological model quantify the dark matter halos of galaxies. Taking into account dynamical friction between dark matter halos, we investigate the past orbital dynamical evolution of ...

Advances in Astronomy, Volume 2010, Issue 1, 2010., 2010 We review numerical works carried out over the last decade on the role of environmental mechanisms in shaping nature of the faintest galaxies known, dwarf spheroidals (dSphs). The combination of tidally induced morphological transformation, termed tidal stirring, with mass loss due to tidal and ram‐pressure stripping aided by heating due to the cosmic ...

The Metallicities of Five Small High-velocity Clouds
The Astrophysical JournalHigh-velocity clouds (HVCs) are multiphase gas structures whose velocities (∣ v _LSR ∣ ≥ 100 km s ^−1 ) are too high to be explained by Galactic disk rotation.

PROBING THE STRUCTURE AND KINEMATICS OF THE TRANSITION LAYER BETWEEN THE MAGELLANIC STREAM AND THE HALO IN H i [PDF]
, 2012 The Magellanic Stream (MS) is a nearby laboratory for studying the fate of cool gas streams injected into a gaseous galactic halo. We investigate properties of the boundary layer between the cool MS gas and the hot Milky Way halo with 21 cm H i ...

The Source of Ionization along the Magellanic Stream [PDF]
The Astrophysical Journal, 2007 Since its discovery in 1996, the source of the bright H-alpha emission (up to 750 mR) along the Magellanic Stream has remained a mystery. There is no evidence of ionising stars within the HI stream, and the extended hot halo is far too tenuous to drive strong shocks into the clouds.
