Questions: Lisa Barsotti on the new and modified LIGO



The detection of infinite conflicts in rotation time is fully restored. Today, LIGO, the Laser Laser Heavyweight Observatory, run by Caltech and MIT, is collaborated, reuniting for fascinating wave hunting and the expensive big phenomena they eat.

Over the past few months, the LIGO seekers, in Washington and Lousiana, have been offline, developing the lasers, mirror and other, allowing the trackers to tune into dissolving waves. on a larger range, extending to 550 million years ago – about 190 million light years longer than before.

How the LIGO trackers turn back, they will be joined by Virgo, the European-based European founder, who also goes on today after doubling the update. With LIGO and Virgo back online, scientists believe the release of vacant waves from the furthest stages of the globe could be a regular occurrence.

MIT News speak to a member of LIGO, Lisa Barsotti, a leading research scientist at the Kavli Institute for Mythology and Spot Research, about the potential future trends.

C: Understanding the new capabilities of the LIGO detector now. What sort of update was made?

A: Both the LIGO trackers are returning online more than ever, as the result of a wide range of developments. Notably, we are doing more to double the laser power in mediation tools to reduce one of the LIGO core output sources – "sound quality", which leads to uncertainty over the length of time visitors get t getting on the projects. "tighten" light, using optum quantum to reduce the noise again.

Along with other developments to mitigate technical sounds (for example sounds introduced by the control scheme or from lighting) we improved awareness of binary double neutron stars with 40 per cent in each finder, running at the time has gone.

C: What do these new capabilities mean for you, as a researcher, who looks through the data from these developed researchers?

A: I'm very pleased that the LIGO finders work in tight light! This new technology has been developed at MIT following a lot of research to match the requirements of the strict LIGO requirements, and our graduate students have been leading the commissioning of this new system. the observation points. It is especially valuable to see that we have achieved LIGO better.

Also, high laser power was developed and developed using another refurbishment and developed here at MIT – “the pouring of acoustic method” that was locked into the main items LIGO that ignores the instability generated by power t high laser. We look forward to seeing many years of work in our labs going forward in this exciting run!

C: What new phenomena do you hope to find, and how quickly will you find them, with these new possibilities?

A: We hope to find larger systems of neutron stars (to date only one), and with thanks to the improved LIGO awareness, we should be able to review these with comparable equivalents. sound. And more, more black holes! The more we find, and the more we can learn about how these systems grow and grow.

If we are lucky, we might be looking at something new, such as a black-neutral star hole system, or maybe something that was unexpected. The LIGO prospectors are not only better than they were before – there was more than a doubling in search of Virgo in Italy for the last eye, which will enhance our ability to detect sources in the atmosphere. enables reproductions with many waves. So if the last visual run is remembered, “O2,” same as multimessenger astronomy, I hope the same one will come, “O3,” as the one in which multilingualism is the norm!
