The team used the Subaru Telescope to observe SDSS J1029+2623, a quasar at ~10 billion light years distance from Earth (from now on referred to as "J 1029"). Thus, their internal structures are not easy to investigate. However, the weakness of this technique is that it traces outflows only along single sight-lines (i.e., one dimension) toward each quasar. Although we cannot see outflows directly because of their faintness, we detect them through absorption features that are recorded in the spectra of the bright sources of light behind them (Note 5). The outflows are eventually distributed to large distances and have a substantial influence on surrounding interstellar/intergalactic regions and on the evolution of galaxies.
It is known that a large amount of gas streams called "outflows" move outward from the central region of quasars. Quasars are bright central regions present in some distant galaxies, and their luminosities are often hundreds of times greater than those of their host galaxies. Although the team had earlier suggested this as a possibility (Note 4), the final conclusion was drawn only through additional observations.ģ-D Observation of a distant quasar by "gravitationally-lensed effect" (an observation in 2010) The following release was received from Shinshu University and is reprinted here in its entirety for the convenience of our readers:Ī team of astronomers (Note 1) have observed a distant (Note 2) gravitationally-lensed quasar (i.e., an Active Galactic Nucleus Note 3) with the Subaru Telescope and concluded that the data indeed present a 3-D view of the structure around a quasar.
