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…
Gravitational microlensing by dark matter in extended structures
Djuna Croon, David McKeen, Nirmal Raj
Dark matter may be in the form of non-baryonic structures such as compact subhalos and boson stars. Structures weighing between asteroid and solar masses may be discovered via grav…
QCD Baryogenesis
Djuna Croon, Jessica N. Howard, Seyda Ipek +1
We explore a simple model which naturally explains the observed baryon asymmetry of the Universe. In this model the strong coupling is promoted to a dynamical quantity, which evolv…
Solitosynthesis and Gravitational Waves
Djuna Croon, Alexander Kusenko, Anupam Mazumdar +1
We study the gravitational wave phenomenology in models of solitosynthesis. In such models, a first order phase transition is precipitated by a period in which non-topological soli…
Dynamical Axions and Gravitational Waves
Djuna Croon, Rachel Houtz, Veronica Sanz
In this paper we explore the possibility of observable gravitational waves as a manifestation of the QCD axion dynamics. In particular, we focus on dynamical axion models which sol…
Stability, reheating and leptogenesis
Djuna Croon, Nicolas Fernandez, David McKeen +1
In a minimal model of leptogenesis, the observed baryon asymmetry is realized after high-scale reheating into the lightest sterile neutrino. We consider constraints on this scenari…
