Discovery of a Probable Physical Triple Quasar
We report the discovery of the first known probable case of a physical triple quasar. A previously known double system, QQ 1429 008 at , is shown to contain a third, fainter QSO component at the same z p 2.076 redshift. Deep optical and IR imaging has failed to reveal a plausible lensing galaxy group or a cluster, and we are unable to construct any viable lensing model that could lead to the ob...
متن کاملAn FeLoBAL Binary Quasar
In an ongoing infrared imaging survey of quasars at Keck Observatory, we have discovered that the z = 1.285 quasar SDSS J233646.2-010732.6 comprises two point sources with a separation of 1. 67. Resolved spectra show that one component is a standard quasar with a blue continuum and broad emission lines; the other is a broad absorption line (BAL) quasar, specifically, a BAL QSO with prominent ab...
متن کاملDiscovery of Radio Emission from the Quasar Sdss J1536+0441, a Candidate Binary Black-hole System
The radio-quiet quasar SDSS J1536+0441 shows two broad-line emission systems that Boroson & Lauer interpret as a candidate binary black-hole system with a separation of 0.1 pc (0.02 mas). From new VLA imaging at 8.5 GHz, two faint sources, separated by 0.97 (5.1 kpc), have been discovered within the quasar’s optical localization region. Each radio source is unresolved, with a diameter of less t...
متن کاملDiscovery of a Probable Physical Triple Quasar1
We report the discovery of the first known probable case of a physical triple quasar (not a gravitational lens). A previously known double system, QQ 1429− 008 at z = 2.076, is shown to contain a third, fainter QSO component at the same redshift within the measurement errors. Deep optical and IR imaging at the Keck and VLT telescopes has failed to reveal a plausible lensing galaxy group or a cl...
متن کاملDiscovery of the lensed quasar system DES
We report the discovery and spectroscopic confirmation of the quad-like lensed quasar system DES J0408-5354 found in the Dark Energy Survey (DES) Year 1 (Y1) data. This system was discovered during a search for DES Y1 strong lensing systems using a method that identified candidates as red galaxies with multiple blue neighbors. DES J0408-5354 consists of a central red galaxy surrounded by three ...
