We report the observational analyses and theoretical interpretations of unusually red galaxies in the Subaru Deep Field (SDF). A careful analysis of the SDF data revealed a population with unusually red near-infrared (NIR) colors of J-K 3-4, with a higher confidence than the previous SDF result. Their surface number density drastically increases at K 22 and becomes roughly the same as that of dusty starburst galaxies detected by submillimeter observations in recent years. These colors are even…

A Hyper Extremely Red Object in the Field near 53W002
Hyper extremely red objects (HEROs) are objects that are very red in near-IR colors (J-K 3). They are speculated to be intrinsically red galaxies at z 2 or Lyman break galaxies at z > 10. We report
High-Redshift Extremely Red Objects in the Hubble Space Telescope Ultra Deep Field Revealed by the GOODS Infrared Array Camera Observations
Using early data from the Infrared Array Camera (IRAC) on the Spitzer Space Telescope, taken for the Great Observatories Origins Deep Survey (GOODS), we identify and study objects that are well
Extremely red galaxies: dust attenuation and classification
We re-address the classification criterion for extremely red galaxies (ERGs) of Pozzetti & Mannucci, which aims to separate, in the I c - K (or R c - K) versus J - K colour-colour diagram, passively
A significant population of red, near-infrared-selected high-redshift galaxies
We use very deep near-infrared photometry of the Hubble Deep Field-South taken with ISAAC on the Very Large Telescope to identify a population of high-redshift galaxies with rest-frame optical colors

Number counts of galaxies are reanalyzed using a semianalytic model (SAM) of galaxy formation based on the hierarchical clustering scenario. Faint galaxies in the Subaru Deep Field (SDF;
The nature of the red disc-like galaxies at high redshift:dust attenuation and intrinsically red stellar populations
We investigate which conditions of dust attenuation and stellar populations allow models of dusty, continuously star-forming, bulge-less disc galaxies at 0.8 z 3.2 to meet the different colour
Submillimetre constraints on hyper-extremely red objects in the Subaru Deep Field
We have mapped the submillimetre wavelength continuum emission from the Subaru Deep Field (SDF) at 450 and 850 µm with the Submillimetre Common-User Bolometer Array (SCUBA) detector on the James
A Substantial Population of Red Galaxies at z > 2: Modeling of the Spectral Energy Distributions of an Extended Sample*
We investigate the nature of the substantial population of high-redshift galaxies with Js - Ks ≥ 2.3 colors recently discovered as part of our Faint Infrared Extragalactic Survey (FIRES). This color
The Formation of the massive galaxies in the SSA22 z=3.1 protocluster
The properties of K-band selected galaxies (K_AB 10^11 M_sun at z_phot \sim 3.1 have colors consistent with those of quiescent galaxies with ages > 0.5 Gyr. This fraction increases to \approx 50%
