TLDR
Using the very-long-baseline interferometer, it is found that the unresolved radio core of 3C 66B shows well-defined elliptical motions with a period of 1.05 ± 0.03 years, which provides a direct detection of a supermassive black hole binary.Abstract:
Supermassive black hole binaries may exist in the centers of active galactic nuclei such as quasars and radio galaxies, and mergers between galaxies may result in the formation of supermassive binaries during the course of galactic evolution. Using the very-long-baseline interferometer, we imaged the radio galaxy 3C 66B at radio frequencies and found that the unresolved radio core of 3C 66B shows well-defined elliptical motions with a period of 1.05 ± 0.03 years, which provides a direct detection of a supermassive black hole binary.read more

TL;DR: In this article, the authors considered the galaxy 3C 66B as the target of the first multimessenger search for gravitational waves and further constrains the chirp mass of the potential supermassive black hole binary in 3c 66B to less than (1.65 ± 0.02) × 10π M_⊙ using data from the NANOGrav 11-year data set.

A coherent method for the detection and estimation of continuous gravitational wave signals using a pulsar timing array
TL;DR: In this article, a likelihood-based method for detection and estimation of a monochromatic continuous gravitational wave signal emitted by a source is presented, where the so-called pulsar terms in the signal that arise due to the breakdown of the long-wavelength approximation are explicitly taken into account.

TL;DR: In this article, ground-based observations of a complete sample of 10 of these infrared galaxies suggest that they represent the initial dust-enshrouded stages of quasars, and a second group of ultraluminous objects selected on the basis of warm infrared colors are found to be preferentially Seyfert galaxies.

Massive black hole binaries in active galactic nuclei
TL;DR: In this article, the authors explore the possibility that some active galactic nuclei may contain two massive black holes in orbit about each other, which suggests a new interpretation for the observed bending and apparent precession of radio jets emerging from these objects.
