A rapidly changing jet orientation in the stellar-mass black-hole system V404 Cygni by Miller-Jones, James, Tetarenko, A.J., Sivakoff, G.R., Middleton, M.J., Altamirano, D., Anderson, Gemma, Belloni, T.M., Fender, R.P., Jonker, P.G., Körding, E.G., Krimm, H.A., Maitra, D., Markoff, S., Migliari, S., Mooley, K.P., Rupen, M.P., Russell, D.M., Russell, T.D., Sarazin, C.L., Soria, R., Tudose, V.

“…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. …”

Dark halo microphysics and massive black hole scaling relations in galaxies by Saxton, C., Soria, Roberto, Wu, K.

An X-Ray-Selected Sample of Candidate Black Holes in Dwarf Galaxies by Lemons, S., Reines, A., Plotkin, Richard, Gallo, E., Greene, J.

“…We present a sample of hard X-ray-selected candidate black holes (BHs) in 19 dwarf galaxies. BH candidates are identified by cross-matching a parent sample of ~44,000 local dwarf galaxies (M* = 3 × 10 9 M☉, z < 0.055) with the Chandra Source Catalog and subsequently analyzing the original X-ray data products for matched sources. …”

Outbursts of the intermediate-mass black hole HLX-1: a wind-instability scenario by Soria, Roberto, Musaeva, A., Wu, K., Zampieri, L., Federle, S., Urquhart, Ryan, van der Helm, E., Farrell, S.

“…We quantify the relative contributions of a bluer component, function of X-ray irradiation, and a redder component, constant and likely coming from an old stellar population. We estimate a black hole mass ≈(2+2−1)×104M⊙ , a spin parameter a/M ≈ 0.9 for moderately face-on view and a peak outburst luminosity ≈0.3 times the Eddington luminosity. …”
