Inside the Stagnation Radius of the Nearest Billion-Solar-Mass Black Hole

J. M. Wrobel, D. W. Pesce, K. E. Nyland

We used the NSF Jansky Very Large Array at a frequency 22\,GHz to study the nearest billion-solar-mass black hole, in the early-type galaxy NGC\,3115 at a distance of 9.7\,Mpc…

Testing the Radio-Selection Method of Dual Active Galactic Nuclei in the Stripe 82 Field

Arran C. Gross, Hai Fu, Adam D. Myers +3

We test the merger-induced dual active galactic nuclei (dAGN) paradigm using a sample of 35 radio galaxy pairs from the SDSS Stripe 82 field. Using Keck optical spectroscopy, we co…

Very Large Array Multi-band Radio Imaging of the Triple AGN Candidate SDSS J0849+1114

Sijia Peng, Zhiyuan Li, Xin Liu +3

Kpc-scale triple active galactic nuclei (AGNs), potential precursors of gravitationally-bound triple massive black holes (MBHs), are rarely seen objects and believed to play an imp…

Is there a sub-parsec-scale jet base in the nearby dwarf galaxy NGC 4395?

Jun Yang, Xiaolong Yang, Joan M. Wrobel +6

NGC 4395 is a dwarf galaxy at a distance of about 4.3 Mpc (scale: ~0.021 pc mas). It hosts an intermediate-mass black hole (IMBH) with a mass between ~10 and ~10 sol…

Toward Astrometric Constraints on a Supermassive Black Hole Binary in the Early-Type Galaxy NGC\,4472

J. M. Wrobel, T. J. W. Lazio

The merger of two galaxies, each hosting a supermassive black hole (SMBH) of mass \,M or more, could yield a bound SMBH binary. For the early-type galaxy NGC\,4472,…

Astrometric Constraints on a Massive Black Hole Binary in NGC\,4472

J. M. Wrobel, T. J. W. Lazio

In an EHT study of a Jy-level target, Safarzadeh et al. (2019) show how astrometric monitoring could constrain massive black hole binaries with the wide separations that make them…
