I basically stopped tweeting a few months ago. I still get a lot of interesting info from twitter, but I didn't know what I was contributing anymore.

The latest episode is out, in which @zemogle and @chrisenorth discuss supernovae, exoplanets and rovers.
@itrharrison & @Dr_Whatson explain what we're learning by looking at the dawn of time.
New podcast home - anchor.fm/pythag-astro
(+ spotify.pythagastro.uk of course)

The SOC and LOC of the @RoyalAstroSoc UK National Astronomy Meeting 2023 (hosted at @cardiffuni @cardiffPHYSX) are happy to announce the call for session proposals is now live on the conference website nam2023.org! (1/3)
Origin and future of CMB telescopes (with me inside them): earlier this year in a @SimonsObs SAT and this afternoon underneath Penzias and Wilson's Horn Antenna.
I used the word "corollary" incorrectly on a telecon yesterday, as if I didn't already have enough to keep me awake at night.

UK cosmologists/astronomers interested in future opportunities with the @SimonsObs join us in September at the RAS for an SO UK community meeting! sites.google.com/view/souk-c…

New paper day, attempting to answer the question - are any distant galaxies too big for our cosmological model? 🐘

In this study we use Extreme Value Statistics (EVS), a method for predicting the most massive object from a given distribution

...sorry, this took me a few days longer than it should.

TFW you get up at 7am whilst on holiday to finish an application, then rather than sending properly it just silently sits in your outbox over the weekend. 😕

Tests of gravity on cosmological scales 👇
Mainly purple (WL+RSD) versus red dashed (CMB+RSD).
ALT 2 sets of ellipses, several overlapping and others shifted.
Is there a course somewhere someone can recommend which would help me practice the skill of /looking at a problem and then writing down the likelihood/?

Exciting news 📢 I have a senior technician post available in my group. If you are interested in using iPSC neuron and microglia models to study neurodegeneration (and make lovely pictures like the one below) this is for you! krb-sjobs.brassring.com/TGne…📢 Please RT and share widely!
Ugh. Council elections, how do they work? What I want is "No Tories". I have 3 votes to distribute amongst these candidates. I'd like to do a 2:1 between Lab:LD, but how am I supposed to know which are the 'lead' candidates??
