Sky and Telescope editor Monica Young speaks with WBUR about how scientists from the LIGO and Virgo gravitational wave observatories, including MIT researchers, may have detected a black hole colliding with a neutron star. Young explains that upgrades made to both observatories should enable investigation of not only individual cosmic events, but also the study of neutron stars and black holes as populations.
Adrian Cho of Science magazine writes that the possible black hole-neutron star merger spotted by LIGO and Virgo would be a “gem for scientists,” but work remains to confirm the signal. Prof. Salvatore Vitale, a LIGO member from MIT, tells Cho: “If you ask me, ‘Would you bet a coffee, your car, or your house on this?’ I would say, ‘I’d bet your car.’”
Gizmodo reporter Ryan Mandelbaum explores the five potential gravitational wave detections made by the LIGO and Virgo observatories in the last month. Prof. Salvatore Vitale explained that the possible detection of a black hole colliding with a neutron star could provide scientists with a better way to measure how quickly the universe is expanding.
“LIGO/VIRGO has opened up its notification process to the public,” explains Ars Technica reporter John Zimmer. “In short, anyone who’s interested can find out what LIGO is seeing within a day of when the LIGO scientists themselves do.”
The LIGO and Virgo gravitational wave detectors have identified five new cosmic events since resuming operations last month, reports Sarah Lewin for Space.com. “The most exciting thing of the beginning of O3 [this third observation round] is that it's clear we are going from one event every few months to a few events every month," explains Prof. Salvatore Vitale.
