Matthieu Béthermin @matbethermin.bsky.social · 24/04/2025I was searching for the cat. There was a strange bump on the guest bed. I looked under and clearly disturbed someone's nap. 030
Matthieu Béthermin @matbethermin.bsky.social · 26/02/2025This little cute ball of fur has managed to cure my super high level of stress in half an hour... Cats are the best! 0150
Matthieu Béthermin @matbethermin.bsky.social · 24/11/2024Quelqu'un s'est fait plaisir en écrivant la notice décrivant les exclusion de garantie d'une assurance. En tant que physicien, je ne suis pas trop inquiet... 020
Matthieu Béthermin @matbethermin.bsky.social · 21/11/2023The final result is there. Our object lies on the high-end of the relation found at lower redshift, but well-below high-z starbursts (red, brown). Despite their morpho-kinematics, our sample is thus not behaving as the extreme bursts studied before at this z. Why? 130
Matthieu Béthermin @matbethermin.bsky.social · 21/11/2023So far, it sounds great, but there is still a step. In many pixels, the SNR of the IR+UV SFR measurements is pretty bad. There is thus a flattening in KS relation at the low end in some object. It is artificial. To correct for it, we used averaged values per regions. 120
Matthieu Béthermin @matbethermin.bsky.social · 21/11/2023Before discussing the astrophysics, I would just like to show our images. We see literally how the gas is distributed in galaxies 1 billions of years after the recombination. In bonus, I added VC875 observation at intermediate resolution observed after the master project. 120
Matthieu Béthermin @matbethermin.bsky.social · 21/11/2023Last week, our paper on the Kennicutt-Schmidt relation in normal star-forming galaxies has been accepted by A&A and posted on arxiv (arxiv.org/abs/2311.08474). I finally found the time for a thread. In collaboration with Cédric Accard, Claire Guillaume, and the ALPINE team! 164
Matthieu Béthermin @matbethermin.bsky.social · 25/10/2023Is it a Tour de France stage or a wine connoisseur pilgrimage? 010
Matthieu Béthermin @matbethermin.bsky.social · 18/10/2023It went from maximizing the surface of exchange to minimizing it quickly. Winter is coming! 051
Matthieu Béthermin @matbethermin.bsky.social · 15/09/2023I just tried hakarl (icelandic fermented shark). As a fench used to very strong and mature cheese, I felt that it was not so strong but very tasty. Am I weird? 040
Matthieu Béthermin @matbethermin.bsky.social · 15/09/2023I was expecting a Gaussian, but it looks more like a Lorentzian... 140
Matthieu Béthermin @matbethermin.bsky.social · 14/09/2023Thirty day in a row. It looks very strang with partial cloud coverage. 170
Matthieu Béthermin @matbethermin.bsky.social · 13/09/2023The show stopped at 11 to allow the travelers to rest. 030
Matthieu Béthermin @matbethermin.bsky.social · 13/09/2023I was planning to sleep tonight, but magnetic fields decided otherwise... 140
Matthieu Béthermin @matbethermin.bsky.social · 13/09/2023I have never seen aurora before, but now I am considering number 2 of the coolest astronomical phenomena observable by eye after total solar eclipse. 070
Matthieu Béthermin @matbethermin.bsky.social · 11/09/2023Iceland is a sort of outdoor and green version of steampunk! 030
Matthieu Béthermin @matbethermin.bsky.social · 04/09/2023Awful swimmer, poor cyclist, medium runner (1550 starters)... Anyway, Gérardmer L triathlon is so hard. We did a part of the race with someone from my club and we cheered each other when it was tough. We finished both and this is what matters in the end! Reaching our goals together >> competition 130
Matthieu Béthermin @matbethermin.bsky.social · 01/09/2023Astronomy is everywhere. This is an ad in the roadbook of the triathlon I will do tomorrow. I am wondering how they brought a race bike on the plateau de Bure though... (fake? chopper?) 100
