The exceptionally powerful TeV γ-ray emitters in the Large Magellanic Cloud [PDF]

open access: yesScience, 2015
A light on the origin of cosmic rays There's a new lab for studying the origins of cosmic rays: our neighbor galaxy, the Large Magellanic Cloud. Astronomers are now making progress on this topic by examining the gamma rays that are produced when cosmic ...

Stellar Population near NGC 2021: Procession of Star Formation in the South Rim of Supergiant Shell LMC 4

open access: yesThe Astronomical Journal
Supergiant shells (SGSs) are the largest interstellar structures where heated and enriched gas flows into the host galaxy’s halo. The SGSs in the Large Magellanic Cloud (LMC) are so close that their stars can be resolved with ground-based telescopes to ...

A 10 kpc stellar substructure at the edge of the Large Magellanic Cloud: Perturbed outer disc or evidence for tidal stripping? [PDF]

open access: yes, 2015
We report the discovery of a substantial stellar overdensity in the periphery of the Large Magellanic Cloud (LMC), found using public imaging from the first year of the Dark Energy Survey.

Properties of the Magellanic Corona

open access: yesThe Astrophysical Journal
We characterize the Magellanic Corona, the warm gaseous halo around the Large Magellanic Cloud (LMC). The Corona is a key ingredient in the formation of the Magellanic Stream and has recently been observed in high-ion absorption around the LMC.

Star-formation history and X-ray binary populations: the case of the Large Magellanic Cloud [PDF]

open access: yes, 2016
In the present work we investigate the link between high-mass X-ray binaries (HMXBs) and star formation in the Large Magellanic Cloud (LMC), our nearest star-forming galaxy.

A LUMINOUS GAMMA-RAY BINARY IN THE LARGE MAGELLANIC CLOUD [PDF]

open access: yes, 2016
Gamma-ray binaries consist of a neutron star or a black hole interacting with a normal star to produce gamma-ray emission that dominates the radiative output of the system.

Deep view of the Large Magellanic Cloud with six years of Fermi -LAT observations [PDF]

open access: yes, 2015
The nearby Large Magellanic Cloud (LMC) provides a rare opportunity of a spatially resolved view of an external star-forming galaxy in gamma-rays. The LMC was detected at 0.1-100GeV as an extended source with CGRO/EGRET and using early observations with ...

JWST Mid-infrared Spectroscopy Resolves Gas, Dust, and Ice in Young Stellar Objects in the Large Magellanic Cloud

open access: yesThe Astrophysical Journal
In this work, we present spectra of 11 young stellar objects (YSOs) taken with the Mid-Infrared Instrument / Medium Resolution Spectroscopy (MRS) instrument on board the James Webb Space Telescope (JWST).

Stellar Population and Energy Feedback in the Supergiant Shell LMC 1

open access: yesThe Astronomical Journal
Supergiant shells (SGSs) are the largest interstellar structures in galaxies and inject hot enriched gas into galactic halos. We have studied SGS LMC 1 to determine quantitatively whether stellar energy feedback is adequate to power the formation of an ...

HIGH-MASS STAR FORMATION TRIGGERED BY COLLISION BETWEEN CO FILAMENTS IN N159 WEST IN THE LARGE MAGELLANIC CLOUD [PDF]

open access: yes, 2015
We have carried out 13CO(J = 2–1) observations of the active star-forming region N159 west in the Large Magellanic Cloud with ALMA. We have found that the CO distribution at a sub-parsec scale is highly elongated with a small width.
