    • Disk-Jet Coupling in the 2017/2018 Outburst of the Galactic Black Hole Candidate X-Ray Binary MAXI J1535-571
      Russell, T.D.; Tetarenko, A.J.; Miller-Jones, James ; Sivakoff, G.R.; Parikh, A.S.; Rapisarda, S.; Wijnands, R.; Corbel, S.; Tremou, E.; Altamirano, D.; Baglio, M.C.; Ceccobello, C.; Degenaar, N.; Eijnden, J.V.D.; Fender, R.; Heywood, I.; Krimm, H.A.; Lucchini, M.; Markoff, S.; Russell, D.M.; Soria, Roberto ; Woudt, P.A. (2019)
      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 the Australia Telescope ...
    • Simultaneous detection of an intrinsic absorber and a compact jet emission in the X-ray binary IGR J17091-3624 during a hard accretion state
      Gatuzz, E.; Díaz Trigo, M.; Miller-Jones, James ; Migliari, S. (2020)
      We present a detailed analysis of three XMM-Newton observations of the black hole low-mass X-ray binary IGR J17091-3624 taken during its 2016 outburst. Radio observations obtained with the Australia Telescope Compact Array ...
    • On the nature of the soft γ-ray emission in the hard state of the black hole transient GRS 1716−249
      Bassi, T.; Malzac, J.; Del Santo, M.; Jourdain, E.; Roques, J.P.; D'Aì, A.; Miller-Jones, James ; Belmont, R.; Motta, S.E.; Segreto, A.; Testa, V.; Casella, P. (2020)
      The black hole transient GRS 1716−249 was monitored from the radio to the γ -ray band during its 2016-2017 outburst. This paper focuses on the spectral energy distribution (SED) obtained in 2017 February-March, when GRS ...
    • An extremely powerful long-lived superluminal ejection from the black hole MAXI J1820+070
      Bright, J.S.; Fender, R.P.; Motta, S.E.; Williams, D.R.A.; Moldon, J.; Plotkin, Richard ; Miller-Jones, James ; Heywood, I.; Tremou, E.; Beswick, R.; Sivakoff, G.R.; Corbel, S.; Buckley, D.A.H.; Homan, J.; Gallo, E.; Tetarenko, A.J.; Russell, T.D.; Green, D.A.; Titterington, D.; Woudt, P.A.; Armstrong, R.P.; Groot, P.J.; Horesh, A.; Horst, A.J.V.D.; Körding, E.G.; McBride, V.A.; Rowlinson, A.; Wijers, R.A.M.J. (2020)
      Black holes in binary systems execute patterns of outburst activity where two characteristic X-ray states are associated with different behaviours observed at radio wavelengths. The hard state is associated with radio ...
    • The MAVERIC Survey: New Compact Binaries Revealed by Deep Radio Continuum Observations of the Galactic Globular Cluster Terzan 5
      Urquhart, R.; Bahramian, Arash ; Strader, J.; Chomiuk, L.; Ransom, S.M.; Wang, Y.; Heinke, C.; Tudor, V.; Miller-Jones, James ; Tetarenko, A.J.; MacCarone, T.J.; Sivakoff, G.R.; Shishkovsky, L.; Swihart, S.J.; Tremou, E. (2020)
      Owing to its massive, dense core, Terzan 5 has the richest population of millisecond pulsars (MSPs) known among Galactic globular clusters. Here we report new deep 2-8 GHz radio continuum observations of Terzan 5 obtained ...
    • Jet-ISM interactions near the microquasars GRS 1758-258 and 1E 1740.7-2942
      Tetarenko, A.J.; Rosolowsky, E.W.; Miller-Jones, James ; Sivakoff, G.R. (2020)
      We present Atacama Large Millimeter/Sub-millimeter Array observations of the candidate jet-ISM interaction zones near the black hole X-ray binaries GRS 1758-258 and 1E 1740.7-2942. Using these data, we map the molecular ...
    • Observations of the disk/jet coupling of MAXI J1820+070 during its descent to quiescence
      Shaw, A.W.; Plotkin, Richard ; Miller-Jones, James ; Homan, J.; Gallo, E.; Russell, D.M.; Tomsick, J.A.; Kaaret, P.; Corbel, S.; Espinasse, M.; Bright, J. (2021)
      Black hole X-ray binaries in the quiescent state (Eddington ratios typically ≲10−5) display softer X-ray spectra (photon indices Γ ∼ 2) compared to higher-luminosity black hole X-ray binaries in the hard state (Γ ∼ 1.7). ...
    • Re-estimating the Spin Parameter of the Black Hole in Cygnus X-1
      Zhao, X.; Gou, L.; Dong, Y.; Zheng, X.; Steiner, J.F.; Miller-Jones, James ; Bahramian, Arash ; Orosz, J.A.; Feng, Y. (2021)
      Cygnus X-1 is a well-studied persistent black hole X-ray binary. Recently, the three parameters needed to estimate the black hole spin of this system, namely the black hole mass M, the orbital inclination i, and the source ...
    • Wind Mass-loss Rates of Stripped Stars Inferred from Cygnus X-1
      Neijssel, C.J.; Vinciguerra, S.; Vigna-Gómez, A.; Hirai, R.; Miller-Jones, James ; Bahramian, Arash ; Maccarone, T.J.; Mandel, I. (2021)
      Recent observations of the high-mass X-ray binary Cygnus X-1 have shown that both the companion star (41 solar masses) and the black hole (21 solar masses) are more massive than previously estimated. Furthermore, the black ...
    • Cygnus X-1 contains a 21-solar mass black hole-Implications for massive star winds

(2021)
      The evolution of massive stars is influenced by the mass lost to stellar winds over their lifetimes. These winds limit the masses of the stellar remnants (such as black holes) that the stars ultimately produce. We used ...
