VLBI Astrometric Procedure and Performance with CHIME/FRB Outriggers
Shion Andrew, Mattias Lazda, Calvin Leung +15
Precise localizations of fast radio bursts (FRBs) to specific environments within their host galaxies with very-long-baseline interferometry (VLBI) have provided valuable insights…
FRB 20250316A: A Brilliant and Nearby One-Off Fast Radio Burst Localized to 13 parsec Precision
FRB Collaboration, Thomas C. Abbott, Daniel Amouyal +83
Precise localizations of a small number of repeating fast radio bursts (FRBs) using very long baseline interferometry (VLBI) have enabled multiwavelength follow-up observations rev…
CHIME/FRB Outriggers: Design Overview
FRB Collaboration, Mandana Amiri, Bridget C. Andersen +66
The Canadian Hydrogen Intensity Mapping Experiment (CHIME) has emerged as the world's premier facility for studying fast radio bursts (FRBs) through its fast transient search backe…
Simultaneous radio and X-ray observations of the transitional millisecond pulsar candidate 3FGL J1544.6-1125
Nina V. Gusinskaia, Amruta D. Jaodand, Jason W. T. Hessels +6
Transitional millisecond pulsars (tMSPs) are neutron-star systems that alternate between a rotation-powered radio millisecond pulsar state and an accretion-disk-dominated low-mass…
Quasi-Simultaneous Radio/X-ray Observations of the Candidate Transitional Millisecond Pulsar 3FGL J1544.6-1125 During its Low-Luminosity Accretion-Disc State
Amruta Jaodand, Adam T. Deller, Nina Gusinskaia +8
3FGL J1544.6-1125 is a candidate transitional millisecond pulsar (tMSP). Similar to the well-established tMSPs - PSR J1023+0038, IGR J18245-2452, and XSS J12270-4859 -- 3FGL J1544.…
Radio and X-ray monitoring of the accreting millisecond X-ray pulsar IGR J17591-2342 in outburst
N. V. Gusinskaia, T. D. Russell, J. W. T. Hessels +7
IGR J175912342 is a new accreting millisecond X-ray pulsar (AMXP) that was recently discovered in outburst in 2018. Early observations revealed that the source's radio emission…
Quasi-simultaneous radio and X-ray observations of Aql X-1: probing low luminosities
N. V. Gusinskaia, J. W. T. Hessels, N. Degenaar +8
Aql X-1 is one of the best-studied neutron star low-mass X-ray binaries. It was previously targeted using quasi-simultaneous radio and X-ray observations during at least 7 differen…
The radio-bright accreting millisecond X-ray pulsar IGR J17591-2342
T. D. Russell, N. Degenaar, R. Wijnands +4
IGR J175912342 is a 527-Hz accreting millisecond X-ray pulsar that was discovered in outburst in 2018 August. In this paper, we present quasi-simultaneous radio and X-ray monito…
Testing the universality of free fall by tracking a pulsar in a stellar triple system
Anne M. Archibald, Nina V. Gusinskaia, Jason W. T. Hessels +6
Einstein's theory of gravity, general relativity, has passed stringent tests in laboratories, elsewhere in the Solar Sytem, and in pulsar binaries. Nevertheless it is known to be i…
LOFAR discovery of the fastest-spinning millisecond pulsar in the Galactic field
C. G. Bassa, Z. Pleunis, J. W. T. Hessels +15
We report the discovery of PSR J09520607, a 707-Hz binary millisecond pulsar which is now the fastest-spinning neutron star known in the Galactic field (i.e., outside of a globu…
Jet quenching in the neutron star low-mass X-ray binary 1RXS J180408.9342058
N. V. Gusinskaia, A. T. Deller, J. W. T. Hessels +6
We present quasi-simultaneous radio (VLA) and X-ray () observations of the neutron star low-mass X-ray binary (NS-LMXB) 1RXS J180408.9342058 (J1804) during its 2015 outbu…
Very hard states in neutron star low-mass X-ray binaries
A. S. Parikh, R. Wijnands, N. Degenaar +4
We report on unusually very hard spectral states in three confirmed neutron-star low-mass X-ray binaries (1RXS J180408.9-342058, EXO 1745-248, and IGR J18245-2452) at a luminosity…
Potential cooling of an accretion-heated neutron star crust in the low-mass X-ray binary 1RXS J180408.9-342058
Aastha S. Parikh, Rudy Wijnands, Nathalie Degenaar +11
We have monitored the transient neutron star low-mass X-ray binary 1RXS J180408.9-342058 in quiescence after its ~4.5 month outburst in 2015. The source has been observed using Swi…
