Yesterday was my last day of working at Google. Perhaps this comes as surprise to you twitter folks, as I haven't widely announced that I left academia to try something new. Here's what I learned in 9 months as a Data Analyst who (temporarily) left Astronomy for Big Tech. 1/n

We (with @VoltarCH) have a new preprint out today: https://t.co/1eSEQepMIv

Long story short: if your only tool is "planarity", everything looks like a plane (of satellite galaxies).

But let me explain. 🧵

[Oliver Müller, Ph.D. @VoltarCH]

@GoAstroMo Was at a coffee break and had a chat in a round. After we left somebody asked me if I'd recognized the person next to me... After realizing it was Bell Burnell I was star struck for the rest of the day. Good thing I didn't realize it during the chat, otherwise might have frozen.

Or the disgust of French bakers when you order a Banette but accidentally call it Baguette.

[Oliver Müller, Ph.D. @VoltarCH]

@dr_guangtou Wait until you learn about the word (and war) for "pain au chocolate" in France.

Any ERC Starting Grantees out there willing to have a chat with me for tips and tricks?

[Oliver Müller, Ph.D. @VoltarCH]

For an ERC Starting Grant, I see that many recommend not to do a "continuation" of your current research project, but rather go for a "dream project" (e.g. https://t.co/8zfqjvQI1j). What if your current project *is* your dream project? Any thoughts on that?

[Oliver Müller, Ph.D. @VoltarCH]

@freyablekman And this year is the first (and last) chance for me. ;-)

[Oliver Müller, Ph.D. @VoltarCH]

ERC Starting Grant call is out. See you all in three months... 😅😂🤣

Kudos to Kravtsov (2024, https://t.co/gyJbgCrEUL). This is how you use a compilation and give credit to the hard work of the community!

@rareflwr41 🤦🤦‍♂️🤦‍♀️

If you needed proof you’re being manipulated on this platform, here it is.

[Marcel S. Pawlowski @8minutesold]

New paper, lead by @Heesters_N, in which we find an increased incidence of significantly lopsided (asymmetric) satellite galaxy distributions around a large sample of observed host galaxies.

Nick tweeted a fantastic thread about it, too. Go check it out and give him a follow!👇

[Oliver Müller, Ph.D. @VoltarCH]

Check out @Heesters_N's second paper of his Ph.D. on anistropies in dwarf galaxy satellite distributions. It's a very cool work and showcases what you actually can do with the growing catalogs of nearby dwarf galaxy systems.

[Nick Heesters, Ph.D. @Heesters_N]

It's paper day! https://t.co/qOjbMW1HuQ, incl. Helmut Jerjen, @VoltarCh, @8minutesold and Jamie Kanehisa. We quantified the degree of lopsidedness in a large sample of isolated satellite systems in the Local Volume and beyond. 🧵

[Oliver Müller, Ph.D. @VoltarCH]

@johngizis I had very good experiences with them. However, I have the feeling that my paper published there slipped under the radar of my peers (maybe due to it not being in one of the big Astro journals?). I would rather save on senior people's page charge money than grade students though.

Weak lensing: Rotation curves of galaxies could be flat up to 1 Mpc.

[Mark Hamill @MarkHamill]

I WANT people to know it was me that liked their tweets.
Now my only option is to reply & write the word "like".
This will seriously cut into my time wishing folks a🎂!
How can we get the powers-that-be to STOP "improving" this site? Grrrrrr! 🤬

@Astronomisty Bringer of entropy.

[Justin Read @ReadDark]

Paper day! @IzzyGrayAstro proposes a new model for NSC formation in tiny dwarfs. Prediction: NSCs should have CMDs with >2, distinct, MS turnoffs. Some nearby CGs like OCen and M54 show exactly this behaviour, suggesting they could be accreted NSCs!

@KarinaVoggel Congrats, so happy for you!
