A ring-like accretion structure in M87 connecting its black hole and jet

Ru-Sen Lu, Keiichi Asada, Thomas P. Krichbaum +118

The nearby radio galaxy M87 is a prime target for studying black hole accretion and jet formation^{1,2}. Event Horizon Telescope observations of M87 in 2017, at a wavelength of 1.3…

The Structure and Dynamics of the Sub-parsec Scale Jet in M87 Based on 50 VLBA Observations Over 17 Years at 43 GHz

R. Craig Walker, Phillip E. Hardee, Frederick B. Davies +2

The central radio source in M87 provides the best opportunity to study jet formation because it has a large angular size for the gravitational radius of the black hole and has a br…

Observations of the Structure and Dynamics of the Inner M87 Jet

R. Craig Walker, Philip E. Hardee, Fred Davies +4

M87 is the best source in which to study a jet at high resolution in gravitational units because it has a very high mass black hole and is nearby. The angular size of the black hol…

Resolving the base of the relativistic jet in M87 at 6 resolution with global mm-VLBI

J. -Y. Kim, R. -S. Lu, T. P. Krichbaum +4

M87 is one of the nearest radio galaxies with a central SMBH and a prominent relativistic jet. Due to its close distance to the observer and the large SMBH mass, the source is one…

Kinematics of the jet in M87 on scales of 100 -- 1000 Schwarzschild radii

F. Mertens, A. P. Lobanov, R. C. Walker +1

Very long baseline interferometry (VLBI) imaging of radio emission from extragalactic jets provides a unique probe of physical mechanisms governing the launching, acceleration, and…

Evidence from the Very Long Baseline Array that J1502SE/SW are Double Hotspots, not a Supermassive Binary Black Hole

J. M. Wrobel, R. C. Walker, H. Fu

SDSS J150243.09+111557.3 is a merging system at z = 0.39 that hosts two confirmed AGN, one unobscured and one dust-obscured, offset by several kiloparsecs. Deane et al. recently re…
