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…
CHIME/FRB Outriggers: KKO Station System and Commissioning Results
Adam E. Lanman, Shion Andrew, Mattias Lazda +43
Localizing fast radio bursts (FRBs) to their host galaxies is an essential step to better understanding their origins and using them as cosmic probes. The CHIME/FRB Outrigger progr…
BURSTT: Bustling Universe Radio Survey Telescope in Taiwan
Hsiu-Hsien Lin, Kai-yang Lin, Chao-Te Li +44
Fast Radio Bursts (FRBs) are bright millisecond-duration radio transients that appear about 1,000 times per day, all-sky, for a fluence threshold 5 Jy ms at 600 MHz. The FRB radio-…

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
