Dark matter through a new lens
My newest paper uses gravitational microlensing to probe extended dark matter objects. Learn how this novel application of artificial intelligence offers fresh insights into one of astrophysics’ biggest mysteries.
A new peak for black holes
New, very high-resolution simulations reveal a double peak in the black hole mass function!
Machine Learning a Manifold
How can a neural network be used to identify a symmetry in a dataset? Collaborators and I have a proposal…
Axion instability supernovae
How new particles inside blue supergiants can lead to extreme explosions!
False vacuum decay 2.0
The prediction of gravitational waves from the early Universe relies on calculations of the false vacuum decay rate. I describe a new method to do so.
Stellar death
How stellar death teaches us about particle physics, explained through a cool plot.
Heavy black holes and light particles
Particle physics through gravitational waves: the existence of the heavy black holes detected by LIGO/Virgo has implications for the lightest particles.
A poem for postdocs
I wrote a little poem for all my friends holding their breath until January 7th.
For Ann
Last summer, one of my role models died. Together with a close friend, I wrote an obituary for Ann Elizabeth Nelson.
Symmetries in particle physics
An explanation of internal symmetries in particle physics without mathematics, using my own face, a mirror, and a simple graph.
