RADIO OBSERVATIONS OF THE HUBBLE DEEP FIELD–SOUTH REGION. II. THE 1.4 GHz CATALOG AND SOURCE COUNTS
This paper is part of a series describing the results from the Australia Telescope Hubble Deep Field–South (ATHDFS) survey obtained with the Australia Telescope Compact Array. This survey consists of observations at 1.4, 2.5, 5.2, and 8.7 GHz, all centered on the Hubble Deep Field–South. Here we present the first results from the extended observing campaign at 1.4 GHz. A total of 466 sources ha...
متن کاملA Catalog of Color - based Redshift Estimates for z < ∼ 4 Galaxies in the Hubble Deep Field
We derive simple empirical color-redshift relations for z < ∼ 4 galaxies in the Hubble Deep Field (HDF) using a linear function of three photometric colors (U − B, B − V , V − I). The dispersion between the estimated redshifts and the spectroscopically observed ones is small for relations derived in several separate color regimes; the dispersions range from σ z ≃ 0.03 to 0.1 for z < ∼ 2 galaxie...
متن کاملA ROSAT Bright Source Catalog Survey with the Swift Satellite
We consider the prospects for a complete survey of the 18,811 sources of the ROSAT All-Sky Survey Bright Source Catalog (BSC) with NASA’s Swift gamma-ray burst (GRB) mission. By observing each BSC source for 500 s with the satellite’s imaging X-ray and UV/optical telescopes, this “Swift Bright (Source) Catalog Survey” (Swift-BCS) would derive <5 source positions for all BSC sources that have no...
متن کاملA new catalog of photometric redshifts in the Hubble Deep Field
Using the newly available infrared images of the Hubble Deep Field in the J , H, and K bands and an optimal photometric method, we have refined a technique to estimate the redshifts of 1067 galaxies. A detailed comparison of our results with the spectroscopic redshifts in those cases where the latter are available shows that this technique gives very good results for bright enough objects (AB(8...
متن کاملDark matter subhalos in the Fermi first source catalog
The Milky Way’s dark matter halo is thought to contain large numbers of smaller subhalos. These objects can contain very high densities of dark matter and produce potentially observable fluxes of gamma rays. In this article, we study the gamma ray sources in the Fermi Gamma Ray Space Telescope’s recently published First Source Catalog and attempt to determine whether this catalog might contain ...
