GALFA Continuum Transit Survey

GALFACTS is a project by the GALFA Continuum Consortium to use the new Arecibo L-band Feed Array (ALFA) to carry out a spectro-polarimetric survey of the sky visible from the Arecibo Observatory.


Precursor Observations

To develop the observing procedures and data processing techniques for the full survey we are engaging in two pilot studies. The target region depicted below was observed during April-May 20054with the single-feed L-band wide receiver system, and in December 2004 with ALFA.

Project Timeline

  • Complete ALFA Precursor Observations - January 2005
  • GALFACTS Project Proposal Submitted - June 1, 2005
  • Initial ALFA image of Pilot Region - September 2005
  • GALFACTS Proposal Approved by NAIC - September 2006
  • Commensal Test Observations with A2174 - October/November 2006
  • GALFACTS Consortium Planning Meeting - January 2007
  • GALFACTS Observations Begin - Fall 2008
    • This schedule is set by the development time for the new
      pulsar/continuum spectrometer which will provide a 300 MHz bandwidth
      for continuum spectro-polarimetry.
  • GALFACTS Observations Completed - 2012
