Carbon in the N159/N160 Complex of the Large Magellanic Cloud
We present a study of carbon in N159/N160, an H II region complex in the low metallicity Large Magellanic Cloud. We have mapped this region, which comprises four distinct molecular clouds spanning a wide range of star-formation activity, in four transitions: CO (J = 1 → 0), CO (J = 2 → 1) and (J = 4 → 3), and [C I] (P1 → P0). Combining these data with existing [C II] (P3/2 → P1/2) observations ...
متن کاملComparison of H II region luminosities with observed stellar ionizing sources in the Large Magellanic Cloud
We estimate the total predicted Lyc emission rates of OB associations for which the complete census of O star spectral types exists. The results are compared to the observed Hα luminosities of the host H II regions. We find evidence for substantial leakage of ionizing photons from some H II regions, while others appear to be radiation bounded. We estimate that overall for the LMC, 0–51% of the ...
متن کاملLarge Magellanic Cloud
Formation of GMCs is one of the most crucial issues in galaxy evolution. I will compare CO and HI in the LMC in 3 dimensional space for the first time aiming at revealing the physical connection between GMCs and associated HI gas at a ∼ 40 pc scale. The present major findings are 1) [total CO intensity] ∝ [total HI intensity] for the 110 GMCs, and 2) the HI intensity tends to increase with the ...
متن کاملFermi Observations of the Large Magellanic Cloud
We report on observations of the Large Magellanic Cloud with the Fermi Gamma-Ray Space Telescope. The LMC is clearly detected with the Large Area Telescope (LAT) and for the first time the emission is spatially well resolved in gamma-rays. Our observations reveal that the bulk of the gamma-ray emission arises from the 30 Doradus region. We discuss this result in light of the massive star popula...
متن کاملThe Distance to the Large Magellanic Cloud
A summary of recent Large Magellanic Cloud distance determinations μLMC is presented, with an eye towards pinpointing the source(s) of the resulting large discrepancies encountered between some of the techniques. Thirty-eight recent (1998-1999) measurements of μLMC are highlighted, the extrema for which (18.07 versus 18.74) are inconsistent with one another at the ∼ >3σ level. The lack of overl...
