Rapid radio brightening of GRB 210702A
G. E. Anderson, T. D. Russell, H. M. Fausey +16
We observed the rapid radio brightening of GRB 210702A with the Australian Telescope Compact Array (ATCA) just 11hr post-burst, tracking early-time radio variability over a 5hr per…
Optical and X-ray Follow-Up to a Globular Cluster Ultraluminous X-ray Source in NGC 4472
Wasundara R. Athukoralalage, Kristen C. Dage, Stephen E. Zepf +4
NGC 4472 is home to five ultraluminous X-ray sources hosted by globular clusters. These sources have been suggested as good black hole candidates in extragalactic globular clusters…
Constraining the nature of the 18-min periodic radio transient GLEAM-X J162759.5-523504.3 via multi-wavelength observations and magneto-thermal simulations
N. Rea, F. Coti Zelati, C. Dehman +13
We observed the periodic radio transient GLEAM-X J162759.5-523504.3 (GLEAM-X J1627) using the Chandra X-ray Observatory for about 30-ks on January 22-23, 2022, simultaneously with…
Astrometry of variable compact radio sources: A search for Galactic black hole X-ray binaries
P. Atri, J. C. A. Miller-Jones, A. Bahramian +7
We use the Very Long Baseline Array to conduct high precision astrometry of a sample of 33 compact, flat spectrum, variable radio sources in the direction of the Galactic plane (Be…
High resolution X-ray spectroscopy of V4641 Sgr during its 2020 outburst
A. W. Shaw, J. M. Miller, V. Grinberg +7
We observed the Galactic black hole X-ray binary V4641 Sgr with the high resolution transmission gratings on Chandra during the source's 2020 outburst. Over two epochs of Chandra g…
1RXH J082623.6-505741: a new long-period cataclysmic variable with an evolved donor and a low mass transfer rate
Kirill V. Sokolovsky, Jay Strader, Samuel J. Swihart +13
We report the discovery of 1RXH J082623.6-505741, a 10.4 hr orbital period compact binary. Modeling extensive optical photometry and spectroscopy reveals a K-t…
Low-Mass X-ray Binaries
Arash Bahramian, Nathalie Degenaar
A large fraction of X-ray sources in our Galaxy are low-mass X-ray binaries, containing a black hole or a neutron star accreting from a gravitationally bound low-mass (1 M$_\…
Monitoring Observations of SMC X-1's Excursions (MOOSE) I: Program Description and Initial High-State Spectral Results
Kristen C. Dage, McKinley Brumback, Joey Neilsen +8
SMC X-1 has exhibited three super-orbital period excursions since the onset of X-ray monitoring beginning with RXTE's launch in 1995. NICER has recently probed a fourth observed ex…
Using Machine Learning to Identify Extragalactic Globular Cluster Candidates from Ground-Based Photometric Surveys of M87
Emilia Barbisan, Jeff Huang, Kristen C. Dage +6
Globular clusters (GCs) have been at the heart of many longstanding questions in many sub-fields of astronomy and, as such, systematic identification of GCs in external galaxies ha…
Investigating the nature and properties of MAXI J1810-222 with radio and X-ray observations
T. D. Russell, M. Del Santo, A. Marino +10
We present results from radio and X-ray observations of the X-ray transient MAXI J1810-222. The nature of the accretor in this source has not been identified. In this paper, we sho…
The MAVERIC Survey: Radio catalogs and source counts from deep Very Large Array imaging of 25 Galactic globular clusters
Laura Shishkovsky, Jay Strader, Laura Chomiuk +7
The MAVERIC survey is the first deep radio continuum imaging survey of Milky Way globular clusters, with a central goal of finding and classifying accreting compact binaries, inclu…
The MAVERIC survey: A catalogue of radio sources in southern globular clusters from the Australia Telescope Compact Array
Vlad Tudor, James C. A. Miller-Jones, Jay Strader +11
Radio continuum observations offer a new window on compact objects in globular clusters compared to typical X-ray or optical studies. As part of the MAVERIC survey, we have used th…
The MAVERIC Survey: The first radio and X-ray limits on the detached black holes in NGC 3201
Alessandro Paduano, Arash Bahramian, James C. A. Miller-Jones +11
The Galactic globular cluster NGC 3201 is the first Galactic globular cluster observed to host dynamically-confirmed stellar-mass black holes, containing two confirmed and one cand…
