Cosmology postdoc at RWTH Aachen, astroparticle physics, dark matter, nerd stuff.
PhD from University of Sydney. He/him
Returning to this accounts after months of inactivity because I actually have something interesting to post.

We just put a new paper on the arXiv, led by a PhD student here in Aachen:
arxiv.org/abs/2503.13183
OLÉ -- Online Learning Emulation in Cosmology
In this work, we present OLÉ, a new online learning emulator for use in cosmological inference. The emulator relies on Gaussian Processes and Principal Component Analysis for efficient data compressio...

Don’t hate follow people. Life’s too short. We are fighting fascism. Don’t make yourself more miserable than necessary.

After leaving Sydney, it's time to start the next chapter of my life. This time in Germany as a postdoc with RWTH Aachen and KIT.
Still using cosmology to learn more about the fundamentals of our universe. 🔭

In the past, I have sometimes done threads for paper releases on the Other Website, so I thought I might do it here, asne of the papers I worked on during my PhD was just published! 🔭
In this work, my collaborators and I investigated how gravitational waves could help us learn about dark matter.

Installing Ubuntu is always a rollercoaster ride. Some random bios option will make the installer crash, but by then your hard drive is already wiped and encrypted. Fun times!

People talk a lot about how moving for jobs in academia can be a hassle (or worse). One thing I did not anticipate was having to deal with all the things I left in storage when I moved to Australia...
I can't help but ask my past self why I thought I would need all of this.

Are introduction posts a thing there? I'm doing one.

I'm Markus! I recently completed my my PhD in cosmology and astroparticle physics at The University of Sydney.
My work has mainly been on how to probe the nature of dark matter via structure formation and astrophysical signals.
