New H - band Galaxy Number Counts : A Large Local Hole in the Galaxy Distribution ?
We examine H-band number counts determined using new photometry over two fields with a combined solid angle of 0.30 deg 2 to H ≈ 19, as well as bright data (H 14) from the 2 Micron All Sky Survey (2MASS). First, we examine the bright number counts from 2MASS extracted for the ≈4000 deg 2 APM survey area situated around the southern galactic pole. We find a deficiency of ≈25 per cent at H = 13 w...
متن کاملThe Local Hole in the Galaxy Distribution : New Optical
We present a new CCD survey of bright galaxies predominantly within the Northern and Southern strips of the 2dF Galaxy Redshift Survey (2dFGRS) areas. We use the new CCD data to check the photographic photometry scales of the 2dFGRS, APM Bright Galaxy Catalogue, APM-Stromlo Redshift Survey, Durham-UKST (DUKST) survey, Millenium Galaxy Catalogue (MGC) and Sloan Digital Sky Survey (SDSS). We find...
متن کاملK - band Galaxy Counts
We present new counts of eld galaxies from more than 20 square arcminutes to a limiting magnitude of K=20 and from 2 square arcminutes to K=21.5. At the faintest magnitudes the counts are slightly higher than those reported previously, though still consistent given the small numbers of galaxies in the two samples.
متن کاملThe Bolocam Lockman Hole Millimeter-Wave Galaxy Survey: Galaxy Candidates and Number Counts
We present results of a new deep 1.1 mm survey using Bolocam, a millimeterwavelength bolometer array camera designed for mapping large fields at fast scan rates, without chopping. A map, galaxy candidate list, and derived number counts are presented. This survey encompasses 324 arcmin to an rms noise level (filtered for point sources) of σ1.1mm ≃ 1.4 mJy beam and includes the entire regions sur...
متن کاملGalaxy number counts – VI . An H - band survey of the Herschel Deep Field
We present H-band infra-red galaxy data to a 3σ limit of H ∼ 22.9 and optical-infra-red colours of galaxies on the William Herschel Deep Field (WHDF). These data were taken from a 7 ′ × 7 ′ area observed for 14 hours with the Ω Prime camera on the 3.5-m Calar Alto telescope. We also present counts derived from the HDF-S NICMOS camera to the limit of H ∼ 29 mag over a 0. ′ 95 × 0. ′ 95 area. Fol...
