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. 🔭

However, all hope is not lost! The next generation of interferometers will be much more sensitive, and our forecasts show that this will be enough to differentiate between the different scenarios, in particular because of their high-redshift sensitivity. This provides a new, complementary probe!

Doing this, it becomes evident that the BBH merger rate is suppressed at high redshift in interacting models, sadly our current generation of gravitational wave detectors LIGO/VIRGO/KAGRA are not sensitive enough to measure this difference.

Using linear (CLASS) and Non-linear (Gadget) structure formation software, we computed the dark matter halo populations for different dark matter scenarios. We could then use semi-analytical galaxy models to predict their galaxy populations, including start formation rates and more! 🔭

This suppression of structures will reduce the number of dark matter halos formed at low masses, with the exact cutoff depending on the model. For warm enough dark matter, or with strong enough interactions, the model will predict too few galaxies, and a limit can be set. 🔭

Many dark matter models, such as warm dark matter, interacting dark matter, and fuzzy dark matter exhibit suppressed structure formation at small scales compared to the standard non-interacting cold dark matter model: these scales are therefore an important probe of dark matter microphysics.

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.

What you have to consider is that you are having a so-called "winter" evening, while this is my Danish summer!
(Cinnamon is lovely, but a good mulled goes beyond that)

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.
