We present near-infrared (near-IR) spectroscopy of three extremely red objects (EROs) using the OHS/CISCO spectrograph at the Subaru Telescope. One target exhibits a strong emission line, which we identify as Hα at z= 1.34. Using new and existing ground-based optical and near-IR imaging, and archival Hubble Space Telescope imaging, we argue that this target is essentially an elliptical galaxy, with an old stellar population of around 4 × 1011 M⊙, but having a dust-enshrouded star-forming…

Aims. The aim of this work is to investigate the physical, structur al and evolutionary properties of old, passive galaxies at z> 1.4 and to place new constraints on massive galaxy formation and
Classification of Extremely Red Objects in the Cosmos Field
We present a study of the classification of z {approx} 1 extremely red objects (EROs), using a combination of Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS), Spitzer Infrared Array

Vigorous star formation hidden by dust in a galaxy at a redshift of 1.4
Near-infrared surveys have revealed a substantial population of faint galaxies that are extremely red in their optical to near-infrared colours. These enigmatic galaxies are about as numerous as
The Redshift of an Extremely Red Object and the Nature of the Very Red Galaxy Population
Infrared surveys have discovered a significant population of bright (K 19) extremely red (R—K 6) objects. Little is known about the properties of these objects on account of their optical faintness
The Dust Content and Opacity of Actively Star-Forming Galaxies
We present far-infrared (FIR) photometry at 150 and 205 km of eight low-redshift starburst galaxies obtained with the Infrared Space Observatory (ISO) ISOPHOT. Five of the eight galaxies are detected
High-redshift star formation in the Hubble Deep Field revealed by a submillimetre-wavelength survey
In the local Universe, most galaxies are dominated by stars, with less than ten per cent of their visible mass in the form of gas. Determining when most of these stars formed is one of the central
Extremely red galaxies: age and dust degeneracy solved?
The extremely red galaxies (ERGs) are defined in terms of their very red optical-to-near IR colours (as R−K>5 or I−K>4). Originally this selection was aimed at selecting old (>1 Gyr) passively
Submillimetre-wavelength detection of dusty star-forming galaxies at high redshift
Optical surveys of the global star-formation rate in high-redshift galaxies show a strong peak in activity at a redshift of z ≈ 1.5, which implies that most of the star formation has already been
The Diversity of Extremely Red Objects
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

We compare the 3D clustering of old passively-evolving and dusty star-forming z 1E ROs from the K20 survey. With detailed simulations of clustering, the comoving correlation length of dusty
