The Widest - Separation Substellar Companion Candidate to a Binary
Direct imaging surveys are powerful tools to search for Jupiter-mass planets around young stars, and those searchers are useful to study the theory of the formation of giant planets with wide orbits around their parent stars. Recent direct imaging surveys show that the projected separation of young planetary-mass companions (PMCs) are surprisingly wide compared with the orbital separations of p...
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 کاملThe Quasar Sdss J153636.22+044127.0: a Double-peaked Emitter in a Candidate Binary Black-hole System
Double-peaked emission lines are believed to be originated from accretion disks around supermassive black holes (SMBHs), and about 3% of z < 0.33 AGNs are found to be double-peaked emitters. The quasar SDSS J153636.22+044127.0 has recently been identified with peculiar broad-line emission systems exhibiting multiple redshifts. We decompose the Hα and Hβ profiles into a circular Keplerian disk l...
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...
