A second candidate magnetic helium core white dwarf and 3 other variable white dwarfs in the globular cluster NGC 6397
Manuel Pichardo Marcano, Liliana E. Rivera Sandoval, Thomas J. Maccarone +5
Using archival Hubble Space Telescope observations, we report the discovery of four variable low-mass white dwarfs () in the globular clu…
The Subparsec-scale Structure and Evolution of Centaurus A. III. A Multi-Epoch Spectral And Polarimetric VLBA Study
Steve Prabu, Steven J Tingay, Arash Bahramian +3
The Centaurus A radio galaxy, due to its proximity, presents itself as one of the few systems that allow the study of relativistic jet outflows at sub-parsec distances from the cen…
Do Neutron Star Ultra-Luminous X-Ray Sources Masquerade as Intermediate Mass Black Holes in Radio and X-Ray?
Teresa Panurach, Kristen C. Dage, Ryan Urquhart +8
Ultraluminous X-ray sources (ULXs) were once largely believed to be powered by super-Eddington accretion onto stellar-mass black holes, although in some rare cases, ULXs also serve…
Monitoring Observations of SMC X-1's Excursions (MOOSE) III: X-ray Spectroscopy of a Warped, Precessing Accretion Disc
Rawan Karam, Kristen C. Dage, Bailey E. Tetarenko +11
The MOOSE (Monitoring Observations of SMC X-1 Excursions) program uses the Neutron Star Interior Composition Explorer Mission (NICER) to monitor the high mass X-ray binary SMC X-1…
The early radio afterglow of short GRB 230217A
G. E. Anderson, G. Schroeder, A. J. van der Horst +9
We present the radio afterglow of short gamma-ray burst (GRB) 230217A, which was detected less than 1 day after the gamma-ray prompt emission with the Australia Telescope Compact A…
A 2.9-hour periodic radio transient with an optical counterpart
N. Hurley-Walker, S. J. McSweeney, A. Bahramian +12
We present a long-period radio transient (GLEAM-X J0704-37) discovered to have an optical counterpart, consistent with a cool main sequence star of spectral type M3. The radio puls…
Catalog of outbursts of neutron star LMXBs
Craig O. Heinke, Junwen Zheng, Thomas J. Maccarone +4
Many X-ray binaries are transiently accreting. Having statistics on their recurrence times is helpful to address questions related to binary evolution and populations, as well as t…
TeV -ray emission near globular cluster Terzan 5 as a probe of cosmic ray transport
Mark R. Krumholz, Roland M. Crocker, Arash Bahramian +1
Cosmic rays travelling through interstellar space have their propagation directions repeatedly scattered by fluctuating interstellar magnetic fields. The nature of this scattering…
A Contact Binary Mis-Classified as an Ellipsoidal Variable: Complications for Detached Black Hole Searches
Tyrone N. O'Doherty, Arash Bahramian, Adelle J. Goodwin +3
Identifying sources exhibiting ellipsoidal variability in large photometric surveys is becoming a promising method to search for candidate detached black holes in binaries. This te…
Swift J1727.8-1613 has the Largest Resolved Continuous Jet Ever Seen in an X-ray Binary
Callan M. Wood, James C. A. Miller-Jones, Arash Bahramian +21
Multi-wavelength polarimetry and radio observations of Swift J1727.8-1613 at the beginning of its recent 2023 outburst suggested the presence of a bright compact jet aligned in the…
An Extreme Ultra-Compact X-ray Binary in a Globular Cluster: Multi-Wavelength Observations of RZ2109 Explored in a Triple System Framework
Kristen C. Dage, Arash Bahramian, Smadar Naoz +6
The globular cluster ultraluminous X-ray source, RZ2109, is a complex and unique system which has been detected at X-ray, ultra-violet, and optical wavelengths. Based on almost 20…
Ultra-deep ATCA imaging of 47 Tucanae reveals a central compact radio source
Alessandro Paduano, Arash Bahramian, James C. A. Miller-Jones +9
We present the results of an ultra-deep radio continuum survey, containing hours of observations, of the Galactic globular cluster 47 Tucanae with the Australia Telescope…
Discovery of a second eclipsing, bursting neutron-star low-mass X-ray binary in the globular cluster Terzan 6
Maureen van den Berg, Jeroen Homan, Craig O. Heinke +4
We have analyzed Chandra and Suzaku observations of the globular cluster Terzan 6, made when the recurrent transient GRS 1747-312 was in quiescence. Our analysis reveals the presen…
