Light Dark Matter through Resonance Scanning
Djuna Croon, Gilly Elor, Rachel Houtz +2
We propose a new out-of-equilibrium production mechanism of light dark matter: resonance scanning. If the dark matter mass evolved in the early Universe, resonant production may ha…
Beyond the Standard Model Explanations of GW190521
Jeremy Sakstein, Djuna Croon, Samuel D. McDermott +2
The LIGO/Virgo collaboration has recently announced the detection of a heavy binary black hole merger, with component masses that cannot be explained by standard stellar structure…
Theoretical uncertainties for cosmological first-order phase transitions
Djuna Croon, Oliver Gould, Philipp Schicho +2
We critically examine the magnitude of theoretical uncertainties in perturbative calculations of first-order phase transitions, using the Standard Model effective field theory as o…
Subaru through a different lens: microlensing by extended dark matter structures
Djuna Croon, David McKeen, Nirmal Raj +1
We investigate gravitational microlensing signals produced by a spatially extended object transiting in front of a finite-sized source star. The most interesting features arise for…
Missing in Action: New Physics and the Black Hole Mass Gap
Djuna Croon, Samuel D. McDermott, Jeremy Sakstein
We demonstrate the power of the black hole mass gap as a novel probe of fundamental physics. New light particles that couple to the Standard Model can act as an additional source o…
Missing in Axion: where are XENON1T's big black holes?
Djuna Croon, Samuel D. McDermott, Jeremy Sakstein
We pioneer the black hole mass gap as a powerful new tool for constraining new particles. A new particle that couples to the Standard Model---such as an axion---acts as an addition…
