Guest post! Today, my #CosmicStories #ScienceandSF blog is hosting a guest post from Prof @astro_jje celebrating the 60th anniversary of #DoctorWho and looking at using the series for education: "What *can't* you teach with Doctor Who?"

Very happy to announce on trans day of visibility a day I will be "visible". My inaugural professorial lecture will be on Wednesday the 7th June at 6pm (refreshments from 5pm).
Attendance is free but please register at

Why is doing public outreach so tiring?
I'm going to have to reduce how much I do for sure!
A short thread on Emmy Noether and giving credit.
Felix Klein gave a lecture at the Mathematical Society of Göttingen #OTD in 1918. The title was “On Hilbert’s first note on the foundations of physics."
Klein included excerpts from letters in which he and Hilbert give priority to Emmy Noether for her results on conservation of energy in general relativity.
It’s easy enough to verify this. Hilbert and Klein couldn't have been more plain about it in their correspondence.

This work was led by @sydonahi with myself, Elizabeth Stanway, Joe Lyman, Anna Faye McLeod and Andrew Levan in the team.
It was one of the two main aims of my Marsden Fund award and I am so happy we got there. 🙂
Oh and if you want to know more Heloise has an excellent summary for other astrophysicist here: https://www.hfstevance.com/research/home-genealogy-170817

New Nature Astronomy Paper alert: "End-to-end study of the host galaxy and genealogy of the first binary neutron star merger"
So excited this paper is finally out! It's been a long road but it's done!

We use BPASS results to analyse the host galaxy NGC 4993 of GW170817. Using the same models end-to-end to make a self contistent analysis of the history of the stars that eventually merged as two neutron star!
From an end-to-end model that characterizes the host galaxy, environment and progenitors of the binary neutron star merger gravitational wave event GW170817, the preferred solution is 2 low-metallicity stars of >10 solar masses that were born during Cosmic Noon, interacted repeatedly and remained bound even through 2 supernovae.
You can see the original summary of Chandrasekhar's presentation in this issue of "The Observatory."

Edward Arthur Milne immediately spoke up after Chandra’s presentation to say he was working on the same problem and had obtained similar results.
