Large 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 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...
متن کاملThe Distance to the Large Magellanic Cloud
I demonstrate that the two unexpected results in the local Universe: anomalous intrinsic (V − I)0 colors of RR Lyrae stars and clump giants in the Galactic center, and very short distances to Magellanic Clouds inferred from clump giants, can be at least partially resolved with a modified coefficient of selective extinction AV /E(V − I). With this modification, I find a new clump-giant distance ...
متن کاملDistance to the Large Magellanic Cloud
We remeasure the “light echo” times to the near and far side of the ring around SN 1987A using the method of Gould (1995) and the new reductions of the original UV spectra by Sonneborn et al. (1996). We obtain an upper limit to the distance to the Large Magellanic Cloud μLMC < 18.37 ± 0.04. This result is very close to Gould’s original value, and contradicts claims that the new spectra measurem...
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...
