Active Galaxy Jets

Prof Worrall, University of Bristol

Herschel Society Free Public Lecture, University of Bath 17^th November 2011

She Assumes Black Holes are at centre of all galaxies
The small scale pattern of one light year or less affects larger pattern of length scales of over 100,000 light years through some feedback process.
Black Holes emit radiation through matter falling into them
Jets are visible to us as products of synchrotron radiation
We can view the jets using X-rays
X-ray jets only last for about 30 years
radio jets are much larger
X-ray Jets can be over 3000 light years in length
I think there must be some other explanation or mechanism to explain 10 million degrees centigrade temperature of hydrogen gas in the jets.
Jets inefficient radiators

(Inefficient at entropy?)

Jets involved in feedback loops between black-hole growth and new star formation.
Does cold dark matter play a part in this process? Can Cold Dark Matter be explained by interactions between relativistic particles and those travelling in “super-lubricated” frictionless tubes faster than the speed of light?

Effective Altruism

It’s not quite Aldous Huxley or George Orwell. I think altruism is what the Dalai Lama perhaps aspires to; kindness, clarity and compassion. This is about humanity rather than about more abstract terms such as the value of money as a metric for happiness or altruism. When dealing with diagnostic labels in mental health, you have to decide whether money is in fact a factor is such a diagnosis or not, given your politics on what money is. Therefore, mental health should be more of a framework that enables those who chose to give up their freedom to live a healthy life, in safety and security within the system. People seek opportunity, therefore by providing such a framework and a decent introduction to a healthy life free of unhappiness is essential to providing a service that is altruistic. We can see this from the British government’s model of social care and welfare programmes, which have proven resilient to mass immigration, a changing demographic, leading to the disruption in

Notes from Energy & Utility Forum 2017

1. Robert Symons, CEO of Western Power Distribution said: “Energy demand could rise by 100% by 2030. Smart grids will be needed to manage electric vehicle charging so that the usage does not exceed the supply capacity at any time during the day.” 2. Spoke to Harry Vickers, Business Development Manager of Camborne Energy Storage, Camborne Capital at the Energy and Utility Forum in London on October 23rd 2017. He told me his company is working with Elon Musk to bring Tesla battery grid storage solutions to the UK. 3. Spoke to Sally Barrett-Williams, Chairman of Energy and Utility Forum on October 23rd, who said subsidies for solar projects had ended and her company’s focus has shifted to energy storage schemes. 4. Spoke to Simon Dowland, PhD, at 13:00 on Sunday 29th October, Simon is now working up in Cambridge at the Cavendish Physics Laboratory at the University of Cambridge, he is working in industry for the company Eight19 Ltd a spin off from a research project to bring ne
