Galaxy number counts - V. Ultra-deep counts: The Herschel and Hubble Deep Fields
We present u, b, r & i galaxy number counts and colours both from the North and South Hubble Space Telescope Deep Fields and from the William Herschel Deep Field. The latter comprises a 7 × 7 area of sky reaching b ∼28.5 at its deepest. Following Metcalfe et al. (1996) we show that simple Bruzual & Charlot evolutionary models which assume exponentially increasing star-formation rates with look-...
متن کاملGalaxy number counts - IV . surveying the Herschel deep field in the near - infrared
We present results from two new near-infrared imaging surveys. One survey covers 47.2 arcmin to K(3σ) = 20m whilst a second, deeper catalogue covers a sub-area of 1.8 arcmin to K(3σ) = 22.75m. Over the entire area we have extremely deep optical photometry in four bandpasses (UBRI), allowing us to track the colour evolution of galaxies to very faint magnitude limits. Our K− band number counts ar...
متن کاملAre Hubble Deep Field Galaxy Counts Whole Numbers?
The Hubble Deep Field (HDF) offers the best view to date of the optical sky at faint magnitudes and small angular scales. Early reports suggested that faint source counts continue to rise to the completeness limit of the data, implying a very large number of galaxies. In this letter, we use the two-point angular correlation function and number-magnitude relation of sources within the HDF in ord...
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...
متن کاملMorphological Number-counts from Ultradeep Hst Images
We discuss the observations leading to the Faint Blue Galaxy problem and the uncertainties upon which faint galaxy models are based. Using deep Hubble Space Telescope (HST) imaging with the Wide Field Planetary Camera (WFPC2), we show how morphological information has been used to shed new light on the problem. Initial results indicate that the giant galaxies (ellipticals and early-type spirals...
