Observational evidence for the origin of X-ray sources in globular clusters
Frank Verbunt, Dave Pooley, Cees Bassa
Low-mass X-ray binaries, recycled pulsars, cataclysmic variables and magnetically active binaries are observed as X-ray sources in globular clusters. We discuss the classification…
The 60 pc Environment of FRB 20180916B
Shriharsh P. Tendulkar, Armando Gil de Paz, Aida Yu. Kirichenko +18
Fast Radio Burst FRB 20180916B in its host galaxy SDSS J015800.28+654253.0 at 149 Mpc is by far the closest-known FRB with a robust host galaxy association. The source also exhibit…
A Massive Pulsar in a Compact Relativistic Binary
John Antoniadis, Paulo C. C. Freire, Norbert Wex +19
Many physically motivated extensions to general relativity (GR) predict significant deviations in the properties of spacetime surrounding massive neutron stars. We report the measu…
X-ray Sources and Their Optical Counterparts in the Galactic Globular Cluster M12 (NGC 6218)
Ting-Ni Lu, Albert K. H. Kong, Cees Bassa +4
We study a Chandra X-ray Observatory ACIS-S observation of the Galactic globular clusterM12. With a 26 ks exposure time, we detect 6 X-ray sources inside the half-mass radius (2.16…
Simultaneous broadband radio and optical emission of meteor trains imaged by LOFAR / AARTFAAC and CAMS
Tammo Jan Dijkema, Cees Bassa, Mark Kuiack +5
We report on simultaneous 30 - 60 MHz LOFAR / AARTFAAC12 radio observations and CAMS low-light video observations of +4 to -10 magnitude meteors at the peak of the Perseid meteor s…
BlueWalker 3 Redux
Anthony Mallama, Richard E. Cole, Scott Harrington +4
The BlueWalker 3 satellite is now fainter than during the first months after deployment. The greatest improvement is that the average maximum luminosity near zenith has been reduce…
