The detection of an older population in the Magellanic Bridge [PDF]
, 2013 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

Models of Tidally Induced Gas Filaments in the Magellanic Stream [PDF]
, 2018 The Magellanic Stream and Leading Arm of H i that stretches from the Large and Small Magellanic Clouds (LMC and SMC) and over 200° of the Southern sky is thought to be formed from multiple encounters between the LMC and SMC. In this scenario, most of the

A search for 3-mm molecular absorption line transitions in the magellanic stream [PDF]
Publications Astronomical Society of AustraliaThe 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 Astrophysical Journal, 2023 This paper proposes a new method for estimating the total quantity of material in moving circumgalactic and intergalactic clouds from O vi measurements. We simulate high-velocity clouds (HVCs) with the FLASH hydrodynamic code and track the ionization and

Symposium - International Astronomical Union, 1991 This model was devised in an attempt to resolve the discrepancy between the values derived for the mass of the Galaxy from distant satellites and from the Magellanic Stream. In contrast to most previous models, the orbit of the Magellanic Cloud system is not bound to the Galaxy, and the Stream was developed as the result of a tidal encounter between ...

Spectral Modeling of the Supersoft X-Ray Source CAL87 Based on Radiative Transfer Codes
The Astrophysical Journal, 2023 Supersoft X-ray sources (SSSs) are white dwarf (WD) binaries that radiate almost entirely below ∼1 keV. Their X-ray spectra are often complex when viewed with the X-ray grating spectrometers, where numerous emission and absorption features are ...

A Dynamically Distinct Stellar Population in the Leading Arm of the Sagittarius Stream
The Astrophysical Journal Letters, 2023 We present a chemical and dynamical analysis of the leading arm (LA) and trailing arm (TA) of the Sagittarius (Sgr) stream, as well as for the Sgr dwarf galaxy core (SC), using red giant branch, main-sequence, and RR Lyrae stars from large spectroscopic ...

BICEP/Keck. XVI. Characterizing Dust Polarization through Correlations with Neutral Hydrogen
The Astrophysical Journal, 2023 We characterize Galactic dust filaments by correlating BICEP/Keck and Planck data with polarization templates based on neutral hydrogen (H i ) observations.

Simulations of the Magellanic Stream in a First Infall Scenario [PDF]
, 2010 Recent high precision proper motions from the Hubble Space Telescope (HST) suggest that the Large and Small Magellanic Clouds (LMC and SMC, respectively) are either on their first passage or on an eccentric long period (>6 Gyr) orbit about the Milky Way (
