Fast Radio Bursts -- Nature's Latest Cosmic Mystery

Ζωντανή μετάδοση στις 4 Μαΐ 2017

Fast
Radio Bursts are millisecond-duration pulses of unknown origin that
were discovered by pulsar astronomers in 2007. A decade on from the
discovery, with only 20 further bursts currently known, fast radio
bursts remain enigmatic sources which parallel the early days of
gamma-ray burst astronomy in the early 1970s. I will tell the story of
their discovery, summarize what we know about them so far, describe the
science opportunities these bursts present, and make predictions for
what we will learn in the next decade.

Host: Peter Williams
Speaker: Duncan Lorimer

What is the age of a black hole?

 
What is the age of a black hole?

Carla René, Pursuing Double Doctorates in Astrophysics and Applied Mathematics
 

There isn’t any direct means of determining the age of a black hole. YET.
We have determined ages by analysing bodies nearby, and then through the process of elimination and other critical thinking skills, have then been able to arrive at one’s age.
Sometimes, if we’re lucky, we can see one’s formation from the direct observation of a star’s final collapse. NASA has the LBT (Large Binocular Telescope) involved in a survey searching for failed supernovae, since the prevailing idea is that stars of a certain mass will go supernovae before forming a black hole.

What
are the basic components of the cosmos? At the deepest levels of
reality—the particles, fields and forces of the smallest slices of
existence—how does the world work?
