Distance scale calibration based on early-type binaries

EPJ Web of Conferences, 2017
Our main goal is to establish a firm empirical calibration of the surface brightness vs. (V-K) color relation for early type stars based on high quality spectroscopic and infrared observations of early-type detached eclipsing systems in the Large ...

Morphology of stellar populations in the Magellanic Clouds using the VMC survey [PDF]

arXiv, 2018
The Magellanic Clouds are nearby dwarf irregular galaxies that represent a unique laboratory for studying galaxy interactions. Their morphology and dynamics have been heavily influenced by their mutual interactions as well as with their interaction(s) with the Milky Way.

Carbon monoxide in the Magellanic Clouds

The Astrophysical Journal, 1982
We have detected 12C0(J =2-1) emission at four positions in the LMC, in the vicinity of 30 Doradus. Three other positions yielded negative results, as did four positions in the main body of the SMC. The results indicate the presence of a giant molecular cloud complex associated with the HII regions N159 and N160A, comparable to galactic complexes.

LSST Survey Strategy in the Galactic Plane and Magellanic Clouds

The Astrophysical Journal Supplement Series, 2023
Galactic science encompasses a wide range of subjects in the study of the Milky Way and Magellanic Clouds, from young stellar objects to X-ray binaries.

The star formation process in the Magellanic Clouds

, 2008
The Magellanic Clouds offer unique opportunities to study star formation both on the global scales of an interacting system of gas-rich galaxies, as well as on the scales of individual star-forming clouds.

Millimeter observations of the Magellanic Clouds

The Astrophysical Journal, 1990
Millimetric observations (1-2 mm) toward the Magellanic Clouds from Antarctica show a good spatial correlation with the IRAS 100-micron emission in the same sky regions. Very likely a cold component coexisting with the warm dust detected by IRAS has been observed. 18 refs.

The Observed O vi Is Just the Tip of the Iceberg: Estimating the Hidden Material in Circumgalactic and Intergalactic Clouds

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

Head-Tail Clouds: Drops to Probe the Diffuse Galactic Halo

, 2011
A head-tail high-velocity cloud (HVC) is a neutral hydrogen halo cloud that appears to be interacting with the diffuse halo medium as evident by its compressed head trailed by a relatively diffuse tail.

Planetary Nebulae in the Magellanic Clouds [PDF]

Symposium - International Astronomical Union, 1991
The proximity, accurately known distance and low line-of-sight reddening give the ideal circumstances to pursue studies of individual stellar populations in the Magellanic Clouds. Here we show how our understanding of the evolution and chemical composition of the planetary nebulae in the Magellanic Clouds has been impacted by imaging and UV ...

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

, 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).
