Week of August 11, 2025
“Where are Gaia’s small black holes?” (Fishbach et al., arXiv: 2508.08986v1, August 12)
Gaia has not found any (or at most one) low-mass black hole, i.e. a black hole with a mass in the so-called mass gap between 2.5 and 5 Msun. This appears much lower than the rate inferred by LIGO from gravitational-wave mergers. The paper shows that this could be due to different evolutionary histories and differences in kicks low-mass black holes receive at birth. [Comment: note, however, that the error on the LIGO rate estimate could be overwhelming.]

“The compact object and innermost ejecta of SN 1987A.” (J. Larsson et al., arXiv:2508.03395, August 5)
Supernova 1987A, which was first observed on Earth on February 23, 1987, was the first naked-eye supernova since Kepler’s supernova in 1604. Detection of neutrinos confirmed that a neutron star was formed in the event. But the detection of the neutron star has remained elusive until it was indirectly discovered with the JWST in 2024 (Fransson et al. 2024, Sci, 383, 898). It was not detected through pulsations, the usual tell-tale sign for a neutron star, but through its ionizing effects on the nearby ejecta, caused either by a pulsar wind nebula or X-rays from the hot neutron star. This follow-up study further constrains the origin of the ionization of the inner ejecta. While it does not yet determine the exact cause of the observed photoionization, it puts important constraints on the natal kick the neutron star may have received at birth.
