01 / THE UNSEEN UNIVERSE
Keduse
Worku.
I work on astrophysics and inference.
Here’s a little of what that looks like.
RELIC NEUTRINOS
Neutrinos have been arounda lot longer than we have.
Some of my research is on relic neutrinos left over from the early universe. I study how gravity affects their motion.
02 / MACS0647 · GRAVITATIONAL LENSING
A closer look atdistant galaxies.
I’ve also worked with JWST observations. My collaborators and I studied distant galaxies behind a cluster called MACS0647, which magnifies their light.
The cluster’s gravity bends the light on its way to us. That helps us see faint galaxies, though it also stretches and distorts what we’re looking at.
We used images to find galaxy candidates, then spectroscopy to confirm redshifts. The distinction matters: a promising candidate still needs to be checked.
WORKING WITH DATA
What’s in the light?
With imaging and spectroscopy, we can estimate stellar masses, star formation rates, and metallicities. That’s the part I work on: using the observations to learn about these early galaxies.
03 / A LITTLE MORE ABOUT ME
And beyond
astrophysics.
I’m most excited by problems where prediction alone isn’t enough. I care about understanding how models behave, where they fail, and what tradeoffs matter.
I’ve applied these tools to studying the early universe, financial modeling, and AI evaluation. I also enjoy communicating these insights clearly, whether to fellow researchers, engineers, or anyone curious about the science.
