The origin of extraterrestrial energetic particles ("cosmic
rays") has puzzled scientists since the pioneering discovery by
Victor Hess in 1912. In the last decade, however, modern
supercomputers and multi-wavelength observations have opened
new...
Abstract: Neutron stars and black holes
represent the inevitable endpoints of stellar evolution for
high-mass stars. Despite the apparent fine-tuning of the physical
conditions necessary to produce them, neutron stars are abundant in
the Galaxy. On...
I will use a real-time general relativistic Black Hole Flight
Simulator to show what really happens inside astronomically
realistic black holes. The inner horizon of a rotating black hole
is the most violent place in the Universe, easily reaching...
The SPHEREx near-infrared space telescope is an all-sky
spectroscopic survey mission launched on March 12th, 2025. In
addition to providing the community with a spectral database
applicable to a wide range of investigations, it is optimized
to...
Abstract: We are now well into the era of
“multiple” large cosmology surveys. Moving forward we anticipate
that much of the best science will come from combining observations
across surveys, so we need to learn how to do this well! I will
describe...
