Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...

The scientists who precisely measure the position of Earth are in a bit of trouble. Their measurements are essential for the ...

That’s the first optically discovered off-nuclear TDE discovered.” A six-panel illustration of a tidal disruption event around a supermassive black hole. NASA, ESA, STScI, Ralf Crawford (STScI) ...

While the supermassive black hole in J2345-0449 is estimated to be between 250 million and 1.4 billion solar masses (there is a big uncertainty because J2345-0449 lacks a central bulge, making the ...

The radio jet recently spotted spans over 200,000 light-years and could be connected to these black holes. A light-year is the distance travelled by light in one year, which is 5.88 trillion miles ...

However, astronomers have long questioned whether long, powerful jets could be spotted in the distant universe because the black holes responsible for them behaved differently in the early universe ...

Astronomers used an array of telescopes to find the most massive radio jet in the early universe. The celestial object is hundreds of thousands of light-years long.

In this talk, Martijn Oei will introduce Porphyrion, a record-breaking jet pair that their team at Caltech recently co-discovered using the Keck I Telescope on Hawaiʻi. Oei is a Postdoctoral Fellow in ...

Porphyrion, observed 6.3 billion years after the Big Bang, has a 23 million light-year-long jet. The J1601+3102 quasar is also of modest size, just 450 million times more massive than the sun.

If Porphyrion’s jets were only as wide as our planet, the black hole that powers them would be the size of an amoeba. However, Gloudemans’ team can only see J1601+3102’s jet as it appears at ...

Experts have determined that the two massive black hole jets discovered show that small things and large things in the universe are “intimately connected.” This discovery is extremely significant ...

A 'sleeping giant' bursts to life Astronomers first became fascinated by the black hole of 1ES 1927+654 in 2018 when it flared with a major outburst seen in optical, ultraviolet and X-ray light.
