ISOCAM 7 micron deep survey of the Lockman Hole: A mid-infrared search for primeval galaxies
We present results of our 7 μm deep survey program madewith ISOCAM, the infrared camera of ISO (InfraredSpace Observatory). We have found 15 sources above a 5 σrms significance in a small selected area (3′× 3′) in the Lockman HI hole. Among the 15 sources, 14 objects have also been observed in the near infrared (NIR: ∼ 2 μm). The majority of the 7 μm sources (11 objects) have NIR counterparts m...
متن کاملDiscovery of a Galaxy Responsible for a DLA System at z = 3.15 and a Near-Infrared Search for Primeval Galaxies
We report the detection, both in line and continuum emission, of a galaxy responsible for a damped Lyα absorption (DLA) system at z = 3.15 projected 2.3 from QSO 2233+131. The star formation rate implied by both the Lyα and restframe far-UV continuum is ∼ 7 M⊙ yr . The galaxy also shows no sign of an active nucleus and has blue colors, both consistent with it being observed early in its star fo...
متن کاملUV Properties of Primeval Galaxies
The problem of UV properties of primeval galaxies is briefly assessed from the theoretical point of view discussing its impact on the definition of the cosmological model.
متن کاملThe Spectral Appearance of Primeval Galaxies
The current and forthcoming observations of large samples of high–redshift galaxies selected according to various photometric and spectroscopic criteria can be interpreted in the context of galaxy formation, by means of models of evolving spectral energy distributions (SEDs). We hereafter present stardust which gives synthetic SEDs from the far UV to the submm wavelength range. These SEDs are d...
متن کاملSe p 19 98 Searches For Primeval Galaxies
A primeval galaxy represents the earliest stages of a galaxy's life and as such provides clues to the early history of the Universe and the evolution of stars and galaxies. Over the last 20 years astronomers have been engaged in the quest to detect the faint signals from these objects, believed to lie at a distance comparable with the size of the Universe. A wide variety of observational techni...
