Powerful relativistic jets are one of the main ways in which accreting black holes provide kinetic feedback to their surroundings. Jets launched from or redirected by the accretion flow that powers them are expected to be affected by the dynamics of the flow, which for accreting stellar-mass black holes has shown evidence for precession1 due to frame-dragging effects that occur when the black-hole spin axis is misaligned with the orbital plane of its companion star2. Recently, theoretical… 

Lorentz Factors of Compact Jets in Black Hole X-Ray Binaries

Compact, continuously launched jets in black hole X-ray binaries (BHXBs) produce radio to optical/IR synchrotron emission. In most BHXBs, an IR excess (above the disk component) is observed when the

Disk–Jet Coupling in the 2017/2018 Outburst of the Galactic Black Hole Candidate X-Ray Binary MAXI J1535–571

MAXI J1535−571 is a Galactic black hole candidate X-ray binary that was discovered going into outburst in 2017 September. In this paper, we present comprehensive radio monitoring of this system using

Accretion and outflow in V404 Cyg

We study the optical evolution of the 2015 outburst in V404 Cyg, with emphasis on the peculiar nebular phase and subsequent decay to quiescence. From the decay time-scale of the Balmer emission

Eclipses of jets and discs of X-ray binaries as a powerful tool for understanding jet physics and binary parameters

We calculate the expected effects on the spectral energy distributions and light curves in X-ray binary jets from eclipses by the donor stars. Jets will be eclipsed for all inclination angles, with

Conflicting Disk Inclination Estimates for the Black Hole X-Ray Binary XTE J1550−564

The dynamical characteristics of XTE J1550−564, a black hole X-ray binary, are well established, and the broadband spectral evolution of the source has been well studied. Its orbital inclination is

Jet collision with accreting tori around SMBHs GRHD and light surface constraints in aggregates of misaligned tori

We explore the possibility of jet collisions with accreting tori orbiting around super-massive black holes. The analysis provides constraints on the formation and the observational evidence of the

Rapid compact jet quenching in the Galactic black hole candidate X-ray binary MAXI J1535−571

We present results from six epochs of quasi-simultaneous radio, (sub-)millimetre, infrared, optical, and X-ray observations of the black hole X-ray binary MAXI J1535−571. These observations show

The hybrid radio/X-ray correlation of the black hole transient MAXI J1348–630

Black hole low mass X-ray binaries in their hard spectral state are found to display two different correlations between the radio emission from the compact jets and the X-ray emission from the inner

Depletion of Bright Red Giants in the Galactic Center during Its Active Phases

Observations in the near-infrared domain showed the presence of the flat core of bright late-type stars inside ∼0.5 pc from the Galactic center supermassive black hole (Sgr A*), while young massive



Regulation of black-hole accretion by a disk wind during a violent outburst of V404 Cygni.

Observations of a sustained outer accretion disk wind in V404 Cyg, which is unlike any seen hitherto, find that the outflowing wind is neutral, has a large covering factor, expands at one per cent of the speed of light and triggers a nebular phase once accretion drops sharply and the ejecta become optically thin.

An elevation of 0.1 light-seconds for the optical jet base in an accreting Galactic black hole system

Relativistic plasma jets are observed in many systems that host accreting black holes. According to theory, coiled magnetic fields close to the black hole accelerate and collimate the plasma, leading

Formation of precessing jets by tilted black hole discs in 3D general relativistic MHD simulations

Gas falling into a black hole (BH) from large distances is unaware of BH spin direction, and misalignment between the accretion disc and BH spin is expected to be common. However, the physics of

A quasi-periodic modulation of the iron line centroid energy in the black hole binary H1743−322

Accreting stellar-mass black holes often show a ‘Type-C’ quasi-periodic oscillation (QPO) in their X-ray flux and an iron emission line in their X-ray spectrum. The iron line is generated through

Global General Relativistic Magnetohydrodynamic Simulation of a Tilted Black Hole Accretion Disk

This paper presents a continuation of our efforts to numerically study accretion disks that are misaligned (tilted) with respect to the rotation axis of a Kerr black hole. Here we present results of

Super-Eddington Mechanical Power of an Accreting Black Hole in M83

There Goes the Neighborhood A mass-accreting black hole in steady-state cannot produce more radiative energy than its gravity can counterbalance, achieving what is known as the Eddington limit.

A 300-parsec-long jet-inflated bubble around a powerful microquasar in the galaxy NGC 7793

It is reported that the large nebula S26 in the nearby galaxy NGC 7793 is powered by a black hole with a pair of collimated jets, similar to the famous Galactic source SS433, but twice as large and a few times more powerful.


The X-ray transient source Sw J1644+57 recently discovered by Swift is believed to be triggered by tidal disruption of a star by a rapidly spinning supermassive black hole (SMBH). For such events,


The Perseus galaxy cluster is known to present multiple and misaligned pairs of cavities seen in X-rays, as well as twisted kiloparsec-scale jets at radio wavelengths; both morphologies suggest that

Simulating galaxy formation with black hole driven thermal and kinetic feedback

The inefficiency of star formation in massive elliptical galaxies is widely believed to be caused by the interactions of an active galactic nucleus (AGN) with the surrounding gas. Achieving a
