Rajarba Survey

Overview

Rajarba is quarter of the sky (π sr) search for radio-loud quasars within
the Epoch of Reionization (z > 6.4) by selecting flat-spectrum, powerful
radio sources which have counterparts that are bright and unresolved
in the near-infrared, but which are faint in the optical.

The search technique includes cross matching available catalogues and
surveys in different wavelengths and supplying them with own observations
only when necessary.

Rajarba Status

Selection Criteria

• Area 30º ≤ Dec ≤ 60º, -30º ≤ Dec ≤ -15º
• Flux density S_325MHz  > 0.018 Jy
• Spectral index α ≤ 0.5 (S_ν ∝ ν^-α)
• Optical magnitude R < 24, I < 24.5
• Infrared unresolved typical K ~ 18 mag
