Blackhole driven explosions

And the dynamic universe
Prof Carole Mundell started in 2007 as prof in Bath

Sun is an ordinary star. Gives us life.

Light colour of distant galaxies tells us about physics of stars. Such as Doppler shift and whether stars are new bright blue stars or old dying red stars.

Cro magnon man drew cave paintings of constellation. Such as Taurus the bull or Orion with a planet crossing it's path leading to a new feature.

Kepler saw moons about Jupiter. Took his gamma ray burst data. Found a pattern for the planets orbit.

Stellar mass black holes a few miles across 300 times mass of our sun collapse at the end of their lives.

Shadow of a black hole. Detecting a black hole: detect mass falling in to black hole such as stars and gas and their movements due to the gravity.

Merlin massive radio telescope near border with Wales. Auger network of detectors in S America.

Non-stellar AGN emissions massive jets of particles and gas emitted explained by black hole.

Spinning disc of light acts like a lens turning light beam passing through it into a laser. Black hole evidence. The water is moving at great speed so that the light beam gets red shifted by 500m/s on one side and emitted as laser beam while on the other side it is blue shifted by 500m/s and there is gain in the system through the energy added by the gravity of the core and other energy gained from system and we can detect this from Earth.

GRB (Gamma Ray Burst) afterglow allows a detection as light fades away over days after gamma ray burst. This is a powerful tool as we detect energy of entire sun over its whole life in a few seconds.

GRB robotic followup as it is such a fleeting event and easily missed by casual observer.

Prof Mundell likes to talk about magnetic fields. Fireball magnetisation. Detecting polarisation of observed light beam to detect magnetic field so polarisation is a magnetic field driven process. Remarkable how magnetic fields survive for so long after initial explosion.

Shrimp has 2 bit low light imaging in its eyes which is a great basic detection set up for astronomy!

Invited to do PhD when she interviewed for masters and is now head of physics at University of Bath.

Criticism for the Tory Government in Britain

My criticism for Jacob Rees-Mogg and the Conservative Party would be from a financial perspective; the Tories have been poor on cost control and paying off stakeholders: extravagant wages and unpaid benefits bills. There have been no real compensation cases for human rights linked to the British education and qualifications system which is indicative of systemic failure at the grassroots. This means that there is a lack of opportunity for British people to do the work that they want to do; they are not being acknowledged. And a phoney social mobility scheme is propagating due to corporate culture being given precedence over British culture in public life.. I think the outlook could be negative for British finances with another credit rating downgrade for the UK, perhaps by two notches! My point is that it's the EU Pinkerton Agents getting the better of Tory government with Donald Tusk lording it over you from his office of power in the EU you won't get treated better in Europ…

Camden Crescent and Hedgemead Park

Here are my thoughts: Did you know that Camden Crescent, originally Camden Place and Upper Camden Place (which is now round the corner) was named after the Earl of Camden, Charles Pratt, who was Chancellor of the Exchequer so sponsored the scheme with his symbol on every door and crest of the exchequer on the decoration at the centre of the crescent? Charles Pratt was actually lord of Camden Place in Chislehurst in Kent. He was mates with William Pitt the Elder from Eton and Cambridge days. It was built 1788-1792 by John Eveleigh the architect.  One third of the 22 house crescent collapsed during a landslip which claimed 136 houses on the slopes of Lansdown Hill leading to the creation of Hedgemead Park below Camden Crescent. John Eveleigh was notoriously bankrupted in Bath, being called to the coffee shop in the Bath Chronicle by his creditors. Earl Camden was famous for supporting Fox’s Libel Act of 1792 which said that libel should be tried as murder with a jury regarding the poin…
