Irts Observations of the Near-infrared Extragalactic Background Light
We have searched for near-infrared extragalactic background light (EBL) in the data from the Near-InfraRed Spectrometer (NIRS) on the Infrared Telescope in Space (IRTS). After subtracting the contribution of faint stars and the zodiacal component based on modeling, a significant isotropic emission is obtained in the wavelength bands from 1.4 µm to 4.0 µm. The spectrum is stellar-like, but shows...

متن کاملOn the origin of near-infrared extragalactic background light anisotropy.
Extragalactic background light (EBL) anisotropy traces variations in the total production of photons over cosmic history and may contain faint, extended components missed in galaxy point-source surveys. Infrared EBL fluctuations have been attributed to primordial galaxies and black holes at the epoch of reionization (EOR) or, alternately, intrahalo light (IHL) from stars tidally stripped from t...
متن کاملThe Cosmic Infrared Background Experiment (ciber): a Sounding Rocket Payload to Study the near Infrared Extragalactic Background Light
The Cosmic Infrared Background Experiment (CIBER) is a suite of four instruments designed to study the near infrared (IR) background light from above the Earth’s atmosphere. The instrument package comprises two imaging telescopes designed to characterize spatial anisotropy in the extragalactic IR background caused by cosmological structure during the epoch of reionization, a low resolution spec...
متن کاملThe Cosmic near Infrared Background: Remnant Light from Early Stars
The redshifted ultraviolet light from early stars at z ∼ 10 contributes to the cosmic near infrared background. We present detailed calculations of its spectrum with various assumptions about metallicity and mass spectrum of early stars. We show that if the near infrared background has a stellar origin, metal-free stars are not the only explanation of the excess near infrared background; stars ...
