Astronomers have employed the Nuclear Spectroscopic Telescope Array (NuSTAR) and the Neutron Star Interior Composition Explorer (NICER) to observe the X-ray pulsar RX J0032.9-7348 in a broadband X-ray energy range. Results of the observational campaign, published April 30 on the arXiv preprint server, yield important insights into the properties of this pulsar.

Using the Neutron star Interior Composition Explorer (NICER) onboard the International Space Station (ISS), astronomers have observed IGR J12580+0134, which is the closest tidal disruption event. Results of the observational campaign, presented April 17 on the preprint server arXiv, shed more light on the nature and behavior of this event.
