Interview about ANITA anomalous events


Following the appearance of the preprint

The ANITA Anomalous Events as Signatures of a Beyond Standard Model Particle, and Supporting Observations from IceCube, 1809.09615

I was interviewed by Live Science about the ANITA anomalous events.  Here is the link to that:

Bizarre Particles Keep Flying Out of Antarctica’s Ice, and They Might Shatter Modern Physics

Neutrinos feeling all of the electrons


In collaboration with Sanjib Kumar Agarwalla, we recently put out a paper on looking for new flavored long-ranged neutrino-electron interactions, using the flavor composition of the IceCube high-energy astrophysical neutrinos:

A Universe’s Worth of Electrons to Probe Long-Range Interactions of High-Energy Astrophysical Neutrinos, 1808.02042

For the first time, we reach the ultimate sensitivity to probe these new interactions by considering the aggregated effect of all of the electrons in the local and distant Universe.
