X-Rays From Neutron Star Merger Still Persist 1,000 Days After Collision

KEY POINTS

  • In 2017, scientists detected X-rays following the collision of two neutron stars
  • It was the first time that X-rays were observed following a gamma ray burst
  • The X-rays were stil observable even 2 1/2 years after the collision
  • Scientists offer possible explanations for the X-ray emission’s strange behavior

A team of researchers can still detect lingering X-rays from a neutron star collision that happened 1,000 days prior. The prolonged X-ray emission continues to puzzle scientists.

It was on Aug. 17, 2017, when the Laser Interferometer Gravitational-wave Observatory (LIGO) and Virgo first detected gravitational waves from the  merger of two neutron stars. Dubbed GW 170817, the event was observed by various telescopes from all over the world within hours of the first detection.

The initial burst was followed by a short-duration gamma ray-burst (GRB) and a slower kilonova. Nine days later, scientists detected an afterglow that was visible

New, most complete start-to-finish view of neutron star merger rewrites the way scientists understand these events — ScienceDaily

It’s been three years since the landmark detection of a neutron star merger from gravitational waves. And since that day, an international team of researchers led by University of Maryland astronomer Eleonora Troja has been continuously monitoring the subsequent radiation emissions to provide the most complete picture of such an event.

Their analysis provides possible explanations for X-rays that continued to radiate from the collision long after models predicted they would stop. The study also reveals that current models of neutron stars and compact body collisions are missing important information. The research was published on October 12, 2020, in the journal Monthly Notices of the Royal Astronomical Society.

“We are entering a new phase in our understanding of neutron stars,” said Troja, an associate research scientist in UMD’s Department of Astronomy and lead author of the paper. “We really don’t know what to expect from this point forward, because

Google’s merger with ITA helped it grow into the giant that the Justice Department is scrutinizing

Google critics and rivals have long warned the search engine is threatening countless industries from shopping to travel by consistently pointing people to its own products and services on the biggest search platform on the Web. And those competing against Google to win over consumers say that the search engine forces them to pay their biggest rival in advertising dollars just to show up.

Google’s dominance in search has drawn more regulatory scrutiny and criticism from rivals and lawmakers in recent months, something that is expected to culminate in the Department of Justice filing an antitrust suit against the company in the coming weeks. Lawmakers are also preparing new legislation to rein in tech’s power, following the publication last week of a congressional investigation that found Google engaged in anticompetitive tactics.

The case by the Justice Department would be its biggest swing yet to rein in the power of tech

Faraday Future engaged in talks to go public through merger, CEO says

Electric vehicle startup Faraday Future aims to close a deal soon to go public through a reverse merger with a special-purchase acquisition company (SPAC), its CEO said on Monday.

“We are working on such a deal … and will be able to announce something hopefully quite soon,” Carsten Breitfeld said of the possibility of a SPAC deal.

Breitfeld declined to say who Faraday is negotiating with or when a deal would close.

A SPAC is a shell company that raises money through an initial public offering to buy an operating entity, typically within two years.

SPACs have emerged as a quick route to the stock market for companies, particularly auto technology startups, and have proven popular with investors seeking to echo Tesla Inc.’s high stock valuation.

Breitfeld, who joined the Los Angeles-based company as CEO last year, also said the company would deliver its first electric luxury SUV, the
