Fast infrared winds during the radio-loud and X-ray obscured stages of the black hole transient GRS 1915+105
J. Sánchez-Sierras, T. Muñoz-Darias, S. E. Motta +10
The black hole transient GRS 1915+105 entered a new phase of activity in 2018, generally characterised by low X-ray and radio fluxes. This phase has been only interrupted by episod…
Chasing the break: Tracing the full evolution of a black hole X-ray binary jet with multi-wavelength spectral modeling
Constanza Echiburú-Trujillo, Alexandra J. Tetarenko, Daryl Haggard +35
Black hole X-ray binaries (BH XRBs) are ideal targets to study the connection between accretion inflow and jet outflow. Here we present quasi-simultaneous, multi-wavelength observa…
Is the M81 Fast Radio Burst Host Globular Cluster Special?
Kristen C. Dage, Arash Bahramian, Clancy W. James +5
We use multiband archival HST observations to measure the photometric and structural parameters of the M81 globular cluster that hosts the Fast Radio Burst FRB 20200120E. Our best-…
MWA rapid follow-up of gravitational wave transients: prospects for detecting prompt radio counterparts
J. Tian, G. E. Anderson, A. J. Cooper +17
We present and evaluate the prospects for detecting coherent radio counterparts to gravitational wave (GW) events using Murchison Widefield Array (MWA) triggered observations. The…
Long-period radio pulsars: population study in the neutron star and white dwarf rotating dipole scenarios
Nanda Rea, Natasha Hurley-Walker, Celsa Pardo-Araujo +9
The nature of two recently discovered radio emitters with unusually long periods of 18min (GLEAM-X J1627-52) and 21min (GPM J1839-10) is highly debated. Their bright radio emission…
Roman CCS White Paper: Characterizing the Galactic population of isolated black holes
Casey Y. Lam, Natasha Abrams, Jeff Andrews +34
Although there are estimated to be 100 million isolated black holes (BHs) in the Milky Way, only one has been found so far, resulting in significant uncertainty about their propert…
The Galactic Center with Roman
Sean K. Terry, Matthew W. Hosek, Jessica R. Lu +31
We advocate for a Galactic center (GC) field to be added to the Galactic Bulge Time Domain Survey (GBTDS). The new field would yield high-cadence photometric and astrometric measur…
The Host Galaxy of FRB 20171020A Revisited
Karen Lee-Waddell, Clancy W. James, Stuart D. Ryder +12
The putative host galaxy of FRB 20171020A was first identified as ESO 601-G036 in 2018, but as no repeat bursts have been detected, direct confirmation of the host remains elusive.…
MAXI J1848-015: The First Detection of Relativistically Moving Outflows from a Globular Cluster X-ray Binary
A. Bahramian, E. Tremou, A. J. Tetarenko +12
Over the past decade, observations of relativistic outflows from outbursting X-ray binaries in the Galactic field have grown significantly. In this work, we present the first detec…
Time-dependent visibility modelling of a relativistic jet in the X-ray binary MAXI J1803-298
C. M. Wood, J. C. A. Miller-Jones, A. Bahramian +17
Tracking the motions of transient jets launched by low-mass X-ray binaries (LMXBs) is critical for determining the moment of jet ejection, and identifying any corresponding signatu…
Tracking the Enigmatic Globular Cluster Ultracompact X-ray Binary X1850--087: Extreme Radio Variability in the Hard State
T. Panurach, R. Urquhart, J. Strader +6
The conditions under which accreting neutron stars launch radio-emitting jets and/or outflows are still poorly understood. The ultracompact X-ray binary X1850--087, located in the…
A candidate magnetic helium core white dwarf in the globular cluster NGC 6397
Manuel Pichardo Marcano, Liliana E. Rivera Sandoval, Thomas J. Maccarone +5
We report a peculiar variable blue star in the globular cluster NGC 6397, using Hubble Space Telescope optical imaging. Its position in the colour-magnitude diagrams, and its spect…
An Observationally-Derived Kick Distribution for Neutron Stars in Binary Systems
Tyrone N. O'Doherty, Arash Bahramian, James C. A. Miller-Jones +5
Understanding the natal kicks received by neutron stars (NSs) during formation is a critical component of modelling the evolution of massive binaries. Natal kicks are an integral i…
Rapid population synthesis of black-hole high-mass X-ray binaries: implications for binary stellar evolution
Isobel M. Romero-Shaw, Ryosuke Hirai, Arash Bahramian +2
We conduct binary population synthesis to investigate the formation of wind-fed high-mass X-ray binaries containing black holes (BH-HMXBs). We evolve multiple populations of high-m…
Monitoring observations of SMC X-1's excursions (MOOSE)-II: A new excursion accompanies spin-up acceleration
Chin-Ping Hu, Kristen C. Dage, William I. Clarkson +11
SMC X-1 is a high-mass X-ray binary showing superorbital modulation with an unstable period. Previous monitoring shows three excursion events in 1996--1998, 2005--2007, and 2014--2…
