The MAVERIC survey: A catalogue of radio sources in southern globular clusters from the Australia Telescope Compact Array

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: 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…
The MAVERIC Survey: Simultaneous Chandra and VLA observations of the transitional millisecond pulsar candidate NGC 6652B

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…
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…

Early spectral evolution of classical novae: consistent evidence for multiple distinct outflows
E. Aydi, L. Chomiuk, L. Izzo +18
The physical mechanism driving mass ejection during a nova eruption is still poorly understood. Possibilities include ejection in a single ballistic event, a common envelope intera…

We present a deep () {\it Chandra} survey of the Galactic globular cluster M30 (NGC 7099). Combining the new Cycle 18 with the previous Cycle 3 observations w…
The MAVERIC Survey: New compact binaries revealed by deep radio continuum observations of the Galactic globular cluster Terzan 5
Ryan Urquhart, Arash Bahramian, Jay Strader +12
Owing to its massive, dense core, Terzan 5 has the richest population of millisecond pulsars known among Galactic globular clusters. Here we report new deep GHz radio contin…
The MAVERIC Survey: Chandra/ACIS Catalog of Faint X-ray sources in 38 Galactic globular clusters
Arash Bahramian, Jay Strader, James C. A. Miller-Jones +11
Globular clusters host a variety of lower-luminosity ( erg s) X-ray sources, including accreting neutron stars and black holes, millisecond pulsars, cataclysmic…
The MAVERIC survey: A hidden pulsar and a black hole candidate in ATCA radio imaging of the globular cluster NGC 6397
Yue Zhao, Craig O. Heinke, Vlad Tudor +9
Using a 16.2 hr radio observation by the Australia Telescope Compact Array (ATCA) and archival Chandra data, we found radio counterparts to 4 known and 3 new X-ray sources wi…
The Swift Bulge Survey: optical and near-IR follow-up featuring a likely symbiotic X-ray binary & a focused wind CV
A. W. Shaw, C. O. Heinke, T. J. Maccarone +13
The nature of very faint X-ray transients (VFXTs) - transient X-ray sources that peak at luminosities - is poorly understood. The faint and of…
