We present the results from a sensitive multiwavelength analysis of the properties of extremely red objects (EROs). Our analysis employs deep RIzJHK photometry of an 85 × 85 region to select a sample of 68 EROs with (R-K) ≥ 5.3 and brighter than K = 20.5 (5 σ). We combine this photometric data set with an extremely deep 1.4 GHz radio map of the field obtained from the VLA. This map reaches a 1 σ limiting flux density of 3.5 μJy, making it the deepest 1.4 GHz map taken, and is sensitive enough…

A multi-wavelength study of the proto-cluster surrounding the z =4.1 radio galaxy TN J1338-1942
We present a 1.2 mm (250 GHz) map obtained with MAMBO on the IRAM 30 m telescope of the central 25 arcmin 2 of the proto-cluster surrounding the z = 4.1 radio galaxy TN J1338−1942. The map reaches a
The faint and extremely red K-band-selected galaxy population in the DEEP2/Palomar fields
We present in this paper an analysis of the faint and red near-infrared (NIR) selected galaxy population found in NIR imaging from the Palomar Observatory Wide-Field Infrared Survey. This survey
We carried out direct measurement of the fraction of dusty sources in a sample of extremely red galaxies with (R - K_s) ≥ 5.3 mag and K_s < 20.2 mag, using 24 μm data from the Spitzer Space
Dusty ERO Search behind Two Massive Clusters
We performed deep K � -band imaging observations of 2 massive clusters, MS 0451.6−0305 at z =0 .55 and MS 0440.5+0204 at z =0 .19, for searching counterparts of the faint sub-mm sources behind these
Extremely red objects in the UKIDSS Ultra Deep Survey Early Data Release
We construct a sample of extremely red objects (EROs) within the UKIDSS Ultra Deep Survey by combining the Early Data Release with optical data from the Subaru/XMM–Newton Deep Field. We find a total
On the Discovery of the First Galaxy Selected at 350 Microns
We report the detection of a 3.6 σ source selected at 350 μm in the Bootes Deep Field. The source, the first short-wavelength submillimeter-selected galaxy (SSG 1), was discovered as part of a

We present initial results from a field survey for extremely red objects [EROs, defined here as (R-K') ≥ 6 mag] covering 154 arcmin2 of sky, from the first of seven deep, wide-field K' images
Optically Faint Microjansky Radio Sources.
It is suggested that most of the radio sources identified are associated with heavily obscured starburst galaxies with redshifts between 1 and 3.5 GHz, however, other mechanisms are discussed and cannot be ruled out with the present observations.
The Nature of Radio Emission from Distant Galaxies: The 1.4 GHz Observations
We have conducted a deep radio survey with the Very Large Array at 1.4 GHz of a region containing the Hubble Deep Field (HDF). This survey overlaps previous observations at 8.5 GHz allowing us to

The Chandra Deep Field North Survey. X. X-Ray Emission from Very Red Objects
The multiwavelength properties of very red objects [VROs; (I-K) ≥ 4] are largely unknown since many of these sources are optically faint (I ≥ 24) and undetected at most wavelengths. Here we provide
