- W2031183485 abstract "We present Hubble Space Telescope and ground-based observations of a pair of galaxies at a redshift of 2.38, which are collectively known as 2142-4420 B1. Both galaxies are luminous extremely red objects (EROs) and are separated by 08. They are embedded within a 100 kpc scale diffuse Lyα nebula (or blob) of luminosity ~1044 ergs s-1. The radial profiles and colors of both red objects are most naturally explained if they are young elliptical galaxies, the most distant galaxies of this type found to date. It is not possible, however, to rule out a model in which they are abnormally compact, extremely dusty starbursting disk galaxies. If they are elliptical galaxies, their stellar populations have inferred masses of ~1011 M☉ and ages of ~7 × 108 yr. Both galaxies have color gradients: their centers are significantly bluer than their outer regions. The surface brightness of both galaxies is roughly 1 order of magnitude greater than would be predicted by the Kormendy relation. A chain of diffuse star formation extending 1'' from the galaxies may be evidence that they are interacting or merging. The Lyα nebula surrounding the galaxies shows apparent velocity substructure of amplitude ~700 km s-1. We propose that the Lyα emission from this nebula may be produced by fast shocks that are powered either by a galactic superwind or by the release of gravitational potential energy." @default.
