MAXI J1957+032: a new accreting millisecond X-ray pulsar in an ultra-compact binary
A. Sanna, P. Bult, M. NG +12
The detection of coherent X-ray pulsations at ~314 Hz (3.2 ms) classifies MAXI J1957+032 as a fast-rotating, accreting neutron star. We present the temporal and spectral analysis p…
The discovery of the 528.6 Hz accreting millisecond X-ray pulsar MAXI J1816-195
Peter Bult, Diego Altamirano, Zaven Arzoumanian +15
We present the discovery of 528.6 Hz pulsations in the new X-ray transient MAXI J1816-195. Using NICER, we observed the first recorded transient outburst from the neutron star low-…
Resolving the inner parsec of the blazar J1924-2914 with the Event Horizon Telescope
Sara Issaoun, Maciek Wielgus, Svetlana Jorstad +27
The blazar J1924-2914 is a primary Event Horizon Telescope (EHT) calibrator for the Galactic Center's black hole Sagittarius A*. Here we present the first total and linearly polari…
