We report new 2 cm VLBA images of the inner radio jet of M87 showing a limb-brightened structure and unambiguous evidence for a faint 3 mas long counterfeature which also appears limb brightened. Multiepoch observations of seven separate jet features show typical speeds of less than a few percent of the speed of light, despite the highly asymmetric jet structure and the implications of the canonical relativistic beaming scenario. The observed morphology is consistent with a two-stream spine…

Intrinsic Structure and Kinematics of the Sub-Parsec Scale Jet of M87

We report new results from a sub-parsec scale study of the inner jet in M87 performed at 15 GHz with the Very Long Baseline Array. We have detected a limb brightened structure of the jet along with a

Fine core-jet structure of the galaxy M87

The fine core-jet structure of the radio galaxy M87 has been investigated in the millimeter-decimeter wave band. A counterjet whose extent is ρ(λ) ≈ 0.036λ pc, where the wavelength λ is expressed in

Jet in jet in M87

New high-resolution Very Long Baseline Interferometer observations of the prominent jet in the M87 radio galaxy show a persistent triple-ridge structure of the transverse 15-GHz profile with a

Fast-spinning Black Holes Inferred from Symmetrically Limb-brightened Radio Jets

This paper theoretically investigates the relations between the structure of relativistic jets and produced synchrotron images, by using a steady, axisymmetric force-free jet model. We especially

Observations of the Structure and Dynamics of the Inner M87 Jet

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 hole is second only to

A new view on the M 87 jet origin: Turbulent loading leading to large-scale episodic wiggling

Context. The nearby, giant radio galaxy M 87 hosts a supermassive black hole (BH) and is well-known for a bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its

A Mechanism for the Triple-ridge Emission Structure of AGN Jets

Recent radio very long baseline interferometry observations of the relativistic jet in the M87 radio galaxy have shown a triple-ridge structure that consists of the conventional limb-brightened

The Structure and Dynamics of the Subparsec Jet in M87 Based on 50 VLBA Observations over 17 Years at 43 GHz

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 bright jet that is

The limb-brightened jet of M87 down to the 7 Schwarzschild radii scale

Messier 87 (M 87) is one of the nearest radio galaxies with a prominent jet extending from sub-pc to kpc scales. Because of its proximity and the large mass of its central black hole (BH), it is one

Kinematics of the jet in M 87 on scales of 100–1000 Schwarzschild radii

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