Figure 1:
EPIC-pn RGB color image produced from data in three energy bands
(red: 0.3-1.0 keV, green: 1.0-2.0 keV and blue: 2.0-7.5 keV).
Each individual image was smoothed with an adaptive intensity
filter. Instrumental
background from an observation with closed filter wheel (from
revolution 59) was subtracted before vignetting and exposure
correction. The XMM-Newton pointing was aimed at

Figure 3:
EPIC spectra of selected X-ray sources in the LMC field. For each source
the best fit to the three EPIC spectra is shown in the upper panels (pn is
always the upper spectrum and the two MOS spectra overlap). The four HMXBs
including the new candidate XMMU J053011.2-655122 are shown on the left.
The right column illustrates the variety of X-ray spectra from sources of
different nature. The spectra of candidate AGN show steeper power-laws
than HMXBs. Spectra of the candidate SNR XMMU J053226.2-655352 and foreground stars
exhibit little flux above 2 keV but can be distinguished by the amount of
absorption. The softest spectrum is detected from the new candidate SSS
XMMU J053056.2-654809 which can be represented by a blackbody model with ![]() |

Figure 4: Best fit model spectrum for EXO 053109-6609.2. It comprises of two power-law components with equal slope absorbed by different amounts of column density ("partial absorber") and a thermal plasma emission component. For parameters see Table 2. |
