TL;DR: In this paper, the authors presented the X-ray source catalog for the 479 ks Chandra exposure of the SDSS J1030+0524 field, which is centered on a region that shows the best evidence to date of an overdensity around a z > 6 quasar, and also includes a Compton-thick Fanaroff-Riley type II radio galaxy at z = 1.7.

TL;DR: ORIGIN as discussed by the authors is a mission for the M3 mission call of ESA aimed at the study of metal creation from the epoch of cosmic dawn, using high-spectral resolution in the soft X-ray band, which can identify the physical conditions of all abundant elements between C and Ni to red-shifts of z=10, and beyond.
