The paper "Indication of a Pulsar Wind Nebula in the hard X-ray emission from SN 1987A" by Dr. Shigehiro Nagataki (Deputy Program Director, iTHEMS), Dr. Masaomi Ono (Research Scientist, iTHEMS) and Mr. Akira Dohi (Junior Research Associate, iTHEMS) was published in the NASA and INAF press releases on February 23, 2021 (SN1987A's 34th birthday!).

The following is a message from Dr. Nagataki;
"We detected high-energy X-rays by NuSTAR, which are likely to come from activities of pulsar wind nebula of SN1987A (it has been a big mystery why the neutron star in SN1987A has not been detected for 34 years since Prof. Koshiba et al. detected neutrinos at the birth of proto-neutron star in SN198A). Our paper will be published by Astrophysical Journal Letters this week."
