Reviving and Higgs Mediated Dark Matter Models in Matter Dominated Freeze-out
Prolay Chanda, Saleh Hamdan, James Unwin
It is quite conceivable that dark matter freeze-out occurred during an early period of matter domination, in which case the evolution and relic abundance differ from standard freez…
What if Planet 9 is a Primordial Black Hole?
Jakub Scholtz, James Unwin
We highlight that the anomalous orbits of Trans-Neptunian Objects (TNOs) and an excess in microlensing events in the 5-year OGLE dataset can be simultaneously explained by a new po…
Ultraviolet Freeze-in and Non-Standard Cosmologies
Nicolás Bernal, Fatemeh Elahi, Carlos Maldonado +1
A notable feature of UV freeze-in is that the relic density is strongly dependent on the highest temperatures of the thermal bath, and a common assumption is that the relevant 'hig…
AEDGE: Atomic Experiment for Dark Matter and Gravity Exploration in Space
Yousef Abou El-Neaj, Cristiano Alpigiani, Sana Amairi-Pyka +129
We propose in this White Paper a concept for a space experiment using cold atoms to search for ultra-light dark matter, and to detect gravitational waves in the frequency range bet…
Sonia Kovalevsky Days: The potential to inspire
Laura P. Schaposnik, James Unwin
The Association of Women in Mathematics has organized and sponsored Sonia Kovalevsky Days for Girls for almost three decades. These one day events are held at colleges and universi…
Markov Chain Models of Refugee Migration Data
Vincent Huang, James Unwin
The application of Markov chains to modelling refugee crises is explored, focusing on local migration of individuals at the level of cities and days. As an explicit example we appl…
Establishing the Dark Matter Relic Density in an Era of Particle Decays
Carlos Maldonado, James Unwin
If the early universe is dominated by an energy density which evolves other than radiation-like the normal Hubble-temperature relation is broken and dark matter reli…
