Another funding opportunity is gone. NSF archived the the Career-Life Balance program which provided supplemental funding when researchers are on family leave.
The small strides we had made toward improving representation in science are being undone so fast.

Definitely thankful to my supervisor for doing this though. It helped build the courage to eventually approach people myself. 😁

Found an old meme of mine from Twitter, and realised that the alt text was a little Easter egg of its own. Proud of past me for this!

Wrapping up on a busy 2024! From @astroai.bsky.social to @scienceacademyswe.bsky.social, and from Cosmo21, Radio 2024 to CCA @flatironinstitute.org, it's been a busy year of presenting results ranging from EoR 21-cm signal extraction with ML, to large-scale simulations, to plans of super-resolution.

Something I tried to emphasize to the Schmidt Foundation a couple of years ago is that one of the ways to intervene in this pattern is for foundations that give out scicomm awards to provide academic winners with research funding so universities see there is fiscal value in supporting scicomm

Heading off to New York for the "Cosmology and galaxy astrophysics with simulations and machine learning" happening at CCA at @flatironinstitute.org!
Lots of interesting science, and of course, Christmas festivities in the city to look forward to. 😁

I’ve seen some posts recently, about the value of basic research, in light of funding cuts and demands that research have immediate economic justification.
Let me collect some info here, in a thread, about why it’s a bad idea to attach those sorts of demands to funding. 🧵 🧪 ⚛️

Prompted by this and a need for distraction I Did Some Math. Turns out most extrasolar planets are quite cauliflower-compatible. A thread, with citations. And laboratory astrophysics. And footnotes.

Going from the first meme to the second took a while. Still, it's amazing how many things I had barely any clue about are now things I am helping make sense of. 😁

Reminded about this meme I made earlier, after some discussions on different hydrodynamical simulations.

Sometimes fitting a model to data "works" based on chi-square and Cash statistics minimisation, but it can still be improved. Thus we look at trends of residuals to access information that such global measures miss, in ui.adsabs.harvard.edu/abs/2024RNAA...!

Spectral Fit Residuals as an Indicator to Increase Model Complexity
Spectral fitting of X-ray data usually involves minimizing statistics like the chi-square and the Cash statistic. Here we discuss their limitations and introduce two measures based on the cumulative s...
