TL;DR
This paper reports the discovery of a quasar companion near SDSS J0927+2943, providing insights into quasar interactions and galaxy evolution during structure formation.
Contribution
It presents the first identification of a quasar companion at a significant distance from a candidate recoiling black hole, highlighting a potential example of ongoing galaxy assembly.
Findings
Discovered a quasar 125 kpc away with a 1400 km/s velocity difference
Suggests the system is in a stage of active structure formation
Provides evidence for complex quasar environments during galaxy evolution
Abstract
We report the discovery of a quasar close to SDSS J0927+2943 (z = 0.713), which is a massive binary / recoiling black hole candidate. The companion quasar is at a projected distance of 125 h_70^{-1} kpc and exhibits a radial velocity difference of ~1400 km/s with respect to the known quasar. We discuss the nature of this peculiar quasar pair and the properties of its environment. We propose that the overall system is caught in the process of ongoing structure formation.
