A Swift study of long-term changes in the X-ray flaring properties of Sagittarius A*
A. Andrés, J. van den Eijnden, N. Degenaar +12
The radiative counterpart of the supermassive black hole at the Galactic Centre, Sagittarius A*, displays flaring emission in the X-ray band atop a steady, quiescent level. Flares…
The MAVERIC Survey: Variable Jet-Accretion Coupling in Luminous Accreting Neutron Stars in Galactic Globular Clusters
T. Panurach, J. Strader, A. Bahramian +9
Accreting neutron stars in low-mass X-ray binaries show outflows -- and sometimes jets -- in the general manner of accreting black holes. However, the quantitative link between the…
Ultraluminous X-ray Sources in Seven Edge-On Spiral Galaxies
Kristen C. Dage, Noah Vowell, Erica Thygesen +8
We investigate a sample of seven edge-on spiral galaxies using Chandra observations. Edge-on spiral galaxies allow us to clearly separate source associated with their star-forming…
A broadband radio view of transient jet ejecta in the black hole candidate X-ray binary MAXI J1535-571
J. Chauhan, J. C. A. Miller-Jones, G. E. Anderson +19
We present a broadband radio study of the transient jets ejected from the black hole candidate X-ray binary MAXI J1535-571, which underwent a prolonged outburst beginning on 2 Sept…
A new radio census of neutron star X-ray binaries
J. van den Eijnden, N. Degenaar, T. D. Russell +16
We report new radio observations of a sample of thirty-six neutron star (NS) X-ray binaries, more than doubling the sample in the literature observed at current-day sensitivities.…
An Analysis of X-Ray Hardness Ratios Between Asynchronous and Non-Asynchronous Polars
Eric Masington, Thomas J. Maccarone, Liliana Rivera Sandoval +3
The subclass of magnetic Cataclysmic Variables (CV), known as asynchronous polars, are still relatively poorly understood. An asynchronous polar is a polar in which the spin period…
The MAVERIC Survey: Simultaneous Chandra and VLA observations of the transitional millisecond pulsar candidate NGC 6652B
Alessandro Paduano, Arash Bahramian, James C. A. Miller-Jones +12
Transitional millisecond pulsars are millisecond pulsars that switch between a rotation-powered millisecond pulsar state and an accretion-powered X-ray binary state, and are though…
Multiwavelength evidence for a new flare-mode transitional millisecond pulsar
Jay Strader, Samuel J. Swihart, Ryan Urquhart +7
We report the discovery of a new low-mass X-ray binary near the center of the unassociated Fermi GeV gamma-ray source 4FGL J0540.0-7552. The source shows the persistent presence of…
The MAVERIC Survey: Dynamical Origin of Radio Sources in Galactic Globular Clusters
Yue Zhao, Craig O. Heinke, Laura Shishkovsky +7
We investigate potential correlations between radio source counts (after background corrections) of 22 Galactic globular clusters (GCs) from the MAVERIC survey, and stellar encount…
Three Ultraluminous X-ray Sources Hosted by Globular Clusters in NGC 1316
Kristen C. Dage, Arunav Kundu, Erica Thygesen +8
We have identified three ultraluminous X-ray sources (ULXs) hosted by globular clusters (GCs) within NGC 1316's stellar system. These discoveries bring the total number of known UL…
Rapid-response radio observations of short GRB 181123B with the Australia Telescope Compact Array
G. E. Anderson, M. E. Bell, J. Stevens +10
We introduce the Australia Telescope Compact Array (ATCA) rapid-response mode by presenting the first successful trigger on the short-duration gamma-ray burst (GRB) 181123B. Early-…
Toward a Larger Sample of Radio Jets from Quiescent Black Hole X-ray Binaries
R. M. Plotkin, A. Bahramian, J. C. A. Miller-Jones +5
Quiescent black hole X-ray binaries (X-ray luminosities <1e34 erg/s) are believed to be fed by hot accretion flows that launch compact, relativistic jets. However, due to their low…
Re-estimating the Spin Parameter of the Black Hole in Cygnus X-1
Xueshan Zhao, Lijun Gou, Yanting Dong +6
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…
Wind mass-loss rates of stripped stars inferred from Cygnus X-1
Coenraad J. Neijssel, Serena Vinciguerra, Alejandro Vigna-Gomez +5
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 pr…
Cygnus X-1 contains a 21-solar mass black hole -- implications for massive star winds
James C. A. Miller-Jones, Arash Bahramian, Jerome A. Orosz +23
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…
Distances to Galactic X-ray Binaries with Gaia DR2
R. M. Arnason, H. Papei, P. Barmby +2
Precise and accurate measurements of distances to Galactic X-ray binaries (XRBs) reduce uncertainties in the determination of XRB physical parameters. We have cross-matched the XRB…
