A radio parallax to the black hole X-ray binary MAXI J1820+070
P. Atri, J. C. A. Miller-Jones, A. Bahramian +18
Using the Very Long Baseline Array and the European Very Long Baseline Interferometry Network we have made a precise measurement of the radio parallax of the black hole X-ray binar…
LRP2020: Astrostatistics in Canada
Gwendolyn Eadie, Arash Bahramian, Pauline Barmby +16
(Abridged from Executive Summary) This white paper focuses on the interdisciplinary fields of astrostatistics and astroinformatics, in which modern statistical and computational me…
Slow Decline and Rise of the Broad [OIII] Emission Line in Globular Cluster Black Hole Candidate RZ2109
Kristen C. Dage, Stephen E. Zepf, Arash Bahramian +6
RZ2109 is the first of several extragalactic globular clusters shown to host an ultraluminous X-ray source. RZ2109 is particularly notable because optical spectroscopy shows it has…
Potential Kick Velocity distribution of black hole X-ray binaries and implications for natal kicks
P. Atri, J. C. A. Miller-Jones, A. Bahramian +14
We use Very Long Baseline Interferometry to measure the proper motions of three black hole X-ray binaries (BHXBs). Using these results together with data from the literature and Ga…
Discovery and Identification of MAXI J1621-501 as a Type I X-ray Burster with a Super-Orbital Period
Nicholas M. Gorgone, Chryssa Kouveliotou, Hitoshi Negoro +26
MAXI J1621-501 is the first Swift/XRT Deep Galactic Plane Survey transient that was followed up with a multitude of space missions (NuSTAR, Swift, Chandra, NICER, INTEGRAL, and MAX…
Observations of the Ultra-compact X-ray Binary 4U 1543-624 in Outburst with NICER, INTEGRAL, Swift, and ATCA
R. M. Ludlam, L. Shishkovsky, P. M. Bult +17
We report on X-ray and radio observations of the ultra-compact X-ray binary 4U 1543-624 taken in August 2017 during an enhanced accretion episode. We obtained NICER monitoring of t…
Chandra reveals a possible ultra-fast outflow in the super-Eddington Be/X-ray binary Swift J0243.6+6124
J. van den Eijnden, N. Degenaar, N. S. Schulz +8
Accretion at super-Eddington rates is expected to be accompanied by strong outflows. Such outflows are observed in Galactic X-ray binaries and extragalactic Ultra-luminous X-ray so…
Evolution of the disc atmosphere in the X-ray binary MXB 1659-298, during its 2015-2017 outburst
G. Ponti, S. Bianchi, B. De Marco +3
We report on the evolution of the X-ray emission of the accreting neutron star (NS) low mass X-ray binary (LMXB), MXB 1659-298, during its most recent outburst in 2015-2017. We det…
An HI absorption distance to the black hole candidate X-ray binary MAXI J1535-571
Jaiverdhan Chauhan, James C. A. Miller-Jones, Gemma E. Anderson +10
With the Australian Square Kilometre Array Pathfinder (ASKAP) we monitored the black hole candidate X-ray binary MAXI J1535--571 over seven epochs from 21 September to 2 October 20…
Flaring, Dust Formation, And Shocks In The Very Slow Nova ASASSN-17pf (LMCN 2017-11a)
E. Aydi, L. Chomiuk, J. Strader +25
We present a detailed study of the 2017 eruption of the classical nova ASASSN-17pf (LMCN 2017-11a), which is located in the Large Magellanic Cloud, including data from AAVSO, ASAS-…
The black hole X-ray transient Swift J1357.2-0933 as seen with Swift and NuSTAR during its 2017 outburst
Aru Beri, B. E. Tetarenko, A. Bahramian +8
We report on observations of black hole Swift J1357.2-0933, a member of the modest population of very faint X-ray transients. This source has previously shown intense dips in the o…
X-Ray Spectral Variability of Ultraluminous X-Ray Sources in Extragalactic Globular Clusters
Kristen C. Dage, Stephen E. Zepf, Mark B. Peacock +4
A number of ultraluminous X-ray sources (ULXs) are physically associated with extragalactic globular clusters (GCs). We undertake a systematic X-ray analysis of eight of the bright…
Multiwavelength survey of X-ray sources in the Sculptor Dwarf Spheroidal Galaxy
R. M. Arnason, P. Barmby, A. Bahramian +2
We present an unprecedented, deep study of the primordial low-mass X-ray binary population in an isolated, lower-metallicity environment. We perform followup observations of previo…
Optical spectroscopy and demographics of redback millisecond pulsar binaries
Jay Strader, Samuel J. Swihart, Laura Chomiuk +12
We present the first optical spectroscopy of five confirmed (or strong candidate) redback millisecond pulsar binaries, obtaining complete radial velocity curves for each companion…
Improved Dynamical Constraints on the Masses of the Central Black Holes in Nearby Low-mass Early-type Galactic Nuclei And the First Black Hole Determination for NGC 205
Dieu D. Nguyen, Anil C. Seth, Nadine Neumayer +17
We improve the dynamical black hole (BH) mass estimates in three nearby low-mass early-type galaxies--NGC 205, NGC 5102, and NGC 5206. We use new \hst/STIS spectroscopy to fit the…
