OMC2/OMC3: A Young Cluster

The following is a near-infrared J (blue), H (green) and K (red) false-color image of the Orion Molecular Cloud (OMC) 2 and 3 region located in the constellation of Orion.

The observations of OMC2/OMC3 were obtained in December 2000 by a Center for Astrophysics (CfA) research scientist, Tom Megeath and U of R graduate student, Dawn Peterson, with SQIID on the 2.1 meter telescope at Kitt Peak National Observatory (KPNO), near Tucson, Arizona. The OMC2/OMC3 region was mapped on a 4x4 grid, and with the SQIID array size of 512 x 512 pixels (and excluding the overlap), the final mosaic size is approximately 1750 x 1750 pixels. With SQIID's pixel size of 0.69 arcsec/pixel, the field of view of the OMC 2/3 image is approximately 20' x 20'. (Note that the following images in this section are all binned down 2x2 pixels.) Images were reduced by U of R graduate student, Dawn Peterson. The following image is labeled with the x-axis in degrees of right ascension and the y-axis in degrees of declination (J2000 coordinates).


Recently, students from the U of R near-infrared lab (including Dawn Peterson and Rob Gutermuth) have been working on the SIRTF young cluster project, and as a result, have observed and performed the image analysis on several young, star formation cluster regions. Three different instruments and telescopes were used to obtain the observations of many such regions. To read more about this research (and see some pretty pictures), click here:
