... However, while low mass stars are usually found to form in loose groups with densities of a few stars per cubic parsecs, high mass stars are known to form in dense clusters with up to 10000 stars per cubic parsec. ... We have undertaken a survey of a cospicuous number of fields around intermediate mass young stars (Herbig Ae/Be stars, HAeBe) with the aim of detect and characterize the groups of young stars that may have formed together with the HAeBe star. ...

... Credit: ISAAC , 8.2-meter VLT , ESO Explanation: It is difficult to hide a galaxy behind a cluster of galaxies. The closer cluster's gravity will act like a huge lens , pulling images of the distant galaxy around the sides and greatly distorting them. ... The foreground cluster can only create such a smooth arc if most of its mass is smoothly distributed dark matter - and therefore not concentrated in the yellow galaxies visible. ...

... Values have been scaled arbitrarily. High ratios are shown in blue, corresponding to blue colors, and low ratios are shown in red, corresponding to red colors. ... Noise combined with background subtraction difficulties in the lower left quadrant of the WISP1 data (see Fig. \ref{Fig:wisp_snr_mskd}) make colors in this area very unreliable. ... The values shown here are typically a factor of ~3 less than those calculated for the Schmidt data, shown in Figure \ref{Fig:bj_alpha}. ...

by virtue of its high galactic latitude (+51 deg), low HI column density (2.2 x 10^20), high declination (increased visibility from KPNO), low IRAS 100 micron cirrus emission , and the absence of many bright stars or nearby rich clusters.
