All guests are welcome!
No knowledge necessary, just a curious mind.

We are able to provide assistance with setting up your telescope or just helping to find your way around the night sky.

Matters from the Discussion Group 9th Oct.

There weren’t many who could make Monday evening’s session but it was very lively none the less.

The “News of the Month” that was presented at the meeting  has been posted on the “Downloads” page HERE

One question that came up, but wasn’t answered, concerned the analysis of the LIGO data.  Basically “How do we know that black holes were involved and how do we know what the before and after masses of the objects was?”
I have had a quick look on the web and came across information on this very question.  The results for the first detection are summarised in the graph below.  I have posted the LIGO Flyer that this graph is from on the “Downloads” page HERE
However, if you want to look at the matter in more detail there is a paper, by B. P. Abbott et al of the LIGO Scientific Collaboration and Virgo Collaboration, on the web at this ADDRESS and you can access the data set at this ADDRESS
