  • The challenge of accurate photometric redshift (photo-z) validation is the elephant in the room that needs to be solved to ensure the full exploitation of upcoming astronomical surveys. Two of the main problems encountered in the development of photo-z techniques are the lack of spectroscopic coverage in feature space (e.g. colours and magnitudes) and the mismatch between photometric error distributions associated with the spectroscopic and photometric samples. Although these issues are well… CONTINUE READING
