Isophotal analysis of M87, using data from the Advanced Camera for Surveys, reveals a projected displacement of 6.8 ± 0.8 pc (∼0.″1) between the nuclear point source (presumed to be the location of the supermassive black hole, SMBH) and the photo-center of the galaxy. The displacement is along a position angle of 307° ± 17° and is consistent with the jet axis. This suggests the active SMBH in M87 does not currently reside at the galaxy center of mass, but is displaced in the counter-jet…

The coalescence of a binary black hole can be accompanied by a large gravitational recoil due to anisotropic emission of gravitational waves. A recoiling supermassive black hole (SBH) can

Modeling the Black Hole Recoil from the Nucleus of M83

GEMINI + GMOS and Chandra emission-line spectroscopy reveal that the Fanaroff-Riley II radio-source J133658.3-295105 is a local object behind the barred-spiral galaxy M83 that is projected onto

Gravitational waves from an SMBH binary in M 87

In this paper, we study gravitational-wave (GW) emission from a hypothetical supermassive black-hole (SMBH) binary at the center of M87. The existence of a SMBH other than that usually identified


The 6 × 10 9 M ⊙ ?> supermassive black hole at the center of the giant elliptical galaxy M87 powers a relativistic jet. Observations at millimeter wavelengths with the Event Horizon Telescope have

The spatially offset quasar E1821+643: new evidence for gravitational recoil

A galaxy merger is expected to cause the formation of a supermassive black hole (SMBH) binary, which itself eventually coalesces through the anisotropic emission of gravitational waves. This may

Constraining a black hole companion for M87* through imaging by the Event Horizon Telescope

The Event Horizon Telescope, a global very long baseline interferometric array observing at a wavelength of 1.3 mm, detected the first image of the M87 supermassive black hole (SMBH). M87 is a

Monsters on the Move: Gravitational Recoil of Supermassive Black Holes in Nearby Elliptical Galaxies

It has long been assumed that Active Galactic Nuclei (AGN) reside at the centers of their host galaxies, but is this really true? A galaxy merger is expected to lead to the formation of a

Recoiling Black Holes: Electromagnetic Signatures, Candidates, and Astrophysical Implications

Supermassive black holes (SMBHs) may not always reside right at the centers of their host galaxies. This is a prediction of numerical relativity simulations, which imply that the newly formed single

A Potential Recoiling Supermassive Black Hole, CXO J101527.2+625911

We have carried out a systematic search for recoiling supermassive black holes (rSMBH) using the Chandra Source and SDSS Cross-Match Catalog. From the survey, we have detected a potential rSMBH, CXO

Aspects of Supermassive Black Hole Growth in Nearby Active Galactic Nuclei

Super-massive black holes (SBHs) have long been identified as the engines of active galactic nuclei (AGNs) and are now considered to play a key role in galaxy evolution. In this dissertation I



The Supermassive Black Hole of M87 and the Kinematics of Its Associated Gaseous Disk

We have obtained long-slit observations of the circumnuclear region of M87 at three different locations, with a spatial sampling of 0.″028 using the Faint Object Camera f/48 spectrograph on board

Ejection of Supermassive Black Holes from Galaxy Cores

Recent numerical relativity simulations have shown that the emission of gravitational waves during the merger of two supermassive black holes (SMBHs) delivers a kick to the final hole, with a

The LINER Nucleus of M87: A Shock-excited Dissipative Accretion Disk

We present long-baseline Faint Object Spectrograph (FOS) spectra of the nuclear accretion disk in M87 (NGC 4486), offset from the nucleus by 0.″6 (42.7 pc) in order to avoid the nuclear continuum.

The nuclear disk in M 87: A review

The disk in the center of M 87 is a prototype for gas orbiting a massive central object. Three sets of HST + COSTAR FOS and FOC observations provide strong evidence that the nuclear disk in M 87 is
