2. The 2MASS Sky

b. 2MASS Extended Sources in the Zone of Avoidance

The so-called "Zone of Avoidance" (ZoA) refers to the area contained within 5° or 10° of the disk plane of the Milky Way. Gas and dust obscures starlight within this region and screens nearly all background extragalactic objects from traditional optical-wavelength surveys; as such, the Galactic plane has historically been avoided by astronomers. 2MASS penetrates this zone with its near-infrared wavelength detectors, providing a "window" that is 90% free of obscuration (relative to that of optical wavelengths). The large nearby spiral galaxy (Figure 1) is just one example of a new 2MASS discovery of objects hidden beyond our Galaxy.

Figure 1

The major limitation that 2MASS suffers in the ZoA is "confusion" noise from starlight that, like background galaxies, is suddenly revealed in the near-infrared. The confusion noise becomes appreciable within an area ±5° of the Galactic plane. The end result is a loss of sensitivity, as the surface density of stars increases exponentially, and a profusion of multiple surface groupings of stars (doubles, triples, etc.) that can, under relatively rare circumstances, mimic galaxies and be picked up by the automated extended source detection and extraction routines (see Section IV.5). The typical reliability of the 2MASS Extended Source Catalog in the Galactic plane ranges from 20 to 80% (compared to >98% well out of the plane), where the primary contaminant is multiple stellar groups.

To demonstrate the ability of 2MASS to find galaxies in the ZoA, probable extended sources (most of which are galaxies or H II regions) from a small area of the sky are given in Table 1 and are shown below. The area corresponds to 53° < glon < 59°, and -2.5° < glat < 4.5°, giving a total of ~40 square degrees. This targeted region is illustrated in the "sky" plot of all 2MASS galaxies in the First Incremental Data Release, shown in Figure 2. The area is populated by both Galactic H II regions, planetary nebulae and extragalactic objects (galaxies). The left panel of the figure shows all of the sources. White dots represent new (previously uncatalogued) extended sources (most of which are probably galaxies), green dots represent galaxies found in NED (thus, previously catalogued), the dashed red line represents the Galactic plane at glat=0°, and the two dotted red lines represents glat=±5°. The right panel shows a subregion near the Galactic plane, defined by 53° < glon < 59°, -2.5° < glat < 4°. Verified extended sources (images shown below) are represented with blue filled circles. White points within the blue box represent false extended sources (typically multiple stars).

Figure 2

Figure 3 shows a mosaic of 45´´×45´´ JHK_s three-color-composite "Postage Stamp Images" of extended sources, located within the area 53° < glon < 59°, -2.5° < glat < 4° and listed in Table 1. Figure 4 shows a much larger view of one of these fields.

Explanation of Figures and Text

The 2MASS images represent a "three-color" RGB composite of the J-band (blue), H-band (green), and K_s-band (red) images.

The DSS image refers to the STScI Digitized Sky Survey. These images are based on photographic (optical-wavelength) data obtained using the Oschin Schmidt Telescope on Palomar Mountain and the UK Schmidt Telescope. The plates were processed into the present compressed digital form with the permission of Caltech, AAO, RAO and ESO. The images from both surveys range in size from 30´´ to 60´´ in width. The position coordinates correspond to the intensity-weighted centroid of the object. The equatorial coordinates are given in units of degrees, as are the galactic coordinates (glon, glat).

The integrated fluxes come from the elliptical isophotal (K_s-band 20 mag per sq. arcsec isophote) aperture measurements. The size of the object refers to the semi-major axis of this elliptical aperture. The measurement uncertainties encorporate the Poisson flux error, including the confusion noise. N.B.: We caution, however, that every source in the table is contaminated by flux from foreground stars, which we have attempted to minimize. The error due to this contamination far outweighs the quoted flux uncertainties (and remains largely unknown).

The Galactic dust extinction is derived from UC Berkeley composite COBE/DIRBE/IRAS/ISSA maps with the zodiacal foreground and confirmed point sources removed (see Schlegel et al. 1998, ApJ, 500, 525). The extinction is computed using the DIRBE 100 and 240 micron data, inferring the dust temperature, then using the 100 micron map to convert to a grid proportional to dust column density. More information can be found here.

NED refers to the NASA Extragalactic Database, a general all-purpose database warehouse of galaxies, including classic catalogs (e.g., NGC) and the latest deep surveys. SIMBAD refers to the database "Set of Identifications, Measurements, and Bibliography for Astronomical Data", maintained by Centre de Donnees Astronomiques de Strasbourg, France. It contains catalogs and information relevant to Galactic objects (e.g., stars, H II regions, planetary nebulae, etc).
