A FLASH HI absorption search in compact sources in the pilot ASKAP interplanetary scintillation field

Paris E. Gordon-Hall, Emily F. Kerrison, Elizabeth K. Mahony +13

The study uses ASKAP interplanetary scintillation measurements to identify compact radio sources and searches for redshifted HI 21 cm absorption between z = 0.4–1, detecting two ne…

PICZL: Image-based Photometric Redshifts for AGN

William Roster, Mara Salvato, Sven Krippendorf +14

Computing photo-z for AGN is challenging, primarily due to the interplay of relative emissions associated with the SMBH and its host galaxy. SED fitting methods, effective in penci…
