Nearly 50 X-ray luminous stars lie above this cloud; more would likely be resolved if the region were on-axis. They contain several dozen embedded protostars, including several with high mass, seen in infrared and X-ray wavelengths. A composite image of the galaxy is shown in Fig. However, the observed rotation velocity cannot support more than a quarter of this mass, and even after adding the contribution from the velocity dispersion the galaxy seems to have a lower kinematical than stellar mass, suggesting that it is not in dynamical equilibrium. Three different regions of the galaxy are outlined and showed in the corresponding panels.

Figure 8 illustrates this with distributions J magnitudes of X-ray source counterparts, one of the principal discriminators in the classifier.

The strength of the excess in the H band appears to be higher for younger, lower mass and lower extinction clusters. Section 3 contains a detailed description of the spectral energy distribution SED analysis of the star clusters, and how we constrain the properties of clusters affected by the red excess. Finally, we already noticed in Haro 11 Adamo et al. The presence of numerous clusters and the perturbed morphology indicate that the galaxy has been involved in a recent merger event.

Two mechanisms, blending and extinction partially embedded phase can remove objects in this region. The BCGs belong to this wide group of irregular and low-mass galaxies. The plume is approximately Nearly X-ray sources are seen in the Chandra field; the total stellar population is below that of the ONC.

The total number of old clusters is This has important implications for a number of related studies of star clusters. It is clear that self-consistent stellar and nebular evolutionary models are not enough to interpret the NIR luminosity properties of these clusters and other mechanisms need saatar be addressed see Section 4 of this work and section 5 in Adamo et al. Both soft and hard approaches are commonly used in modern statistical applications Wahba ; Liu et al.

Such proximity suggests that it has recently formed. Lopez-Sanchez for making the saturated three-colour image of the target.

Second, X-ray samples miss many young AB stars because intrinsic X-ray emission is weak or absent, although some are found due to lower mass companions e.

False sources are seen in the PSFs of bright sources red circles with black arrows and occasionally in diffuse patches cyan arrow. We observe, as in Haro 11, that the use of the IR and the commonly used I band data results in overestimates of age and mass in clusters affected by the NIR excess.

Unfortunately, for the more challenging MYStIX clusters that have bright, spatially variable nebulosity and many thousands of Galactic field stars unrelated to the star-forming region, straightforward application of established infrared excess criteria give samples that are clearly dominated by non-cluster members.

If we assume that the outer shell marked in Fig. The purple filled dots are the 11 clusters detected in the plume.

This reduces contamination by uninteresting field stars that can overwhelm proximity-only source matching procedures. When mid-infrared nebular emission primarily from PAH molecules is strong and spatially variable, the sensitivity of any algorithm seeking unresolved stellar sources is reduced Kuhn et al.

As already expected there are sataar clusters sitting below these limits. King 3Michael A. The fraction of nebular emission contributing to the integrated fluxes increases and last longer in the NIR see Adamo et al. Several luminous mid-infrared sources in the central 10′ aligned along the Galactic plane mark very young embedded clusters.

The median values of the residuals in the H and I bands of star clusters not affected by red excess are also included for each age, mass and extinction bin black crosses. For the other clusters, distances are estimated by a variety of techniques: This scenario could also explain why we detect those clusters at optical wavelengths.

This sample and related data products will be used to seek new empirical constraints on theoretical models of cluster formation and dynamics, mass segregation, OB star formation, star formation triggering on the periphery of H II regions, and the survivability of protoplanetary disks in H II regions. Source candidates are found a local bumps in a maximum likelihood reconstruction of the image using local PSFs; this method is more sensitive and reliable than commonly used procedures based on the wavelet transform Townsley et al.

The angular size of the starburst region is quite small major axis about Satwr and cyan pluses indicate MYStIX high-reliability sources and red circles indicate additional lower-reliability sources. For each filter we list in the table:
