A minimal model of inflation and dark radiation
Kristjan Kannike, Aleksei Kubarski, Luca Marzola +1
We show that a minimal extension of the Standard Model including a new complex scalar field can explain inflation and the observed effective number of neutrinos. The real part of t…
Dark Matter Effects On Neutron Star Properties
John Ellis, Gert Hütsi, Kristjan Kannike +3
We study possible effects of a dark matter (DM) core on the maximum mass of a neutron star (NS), on the mass-radius relation and on the NS tidal deformability parameter . We sho…
The EDGES 21 cm Anomaly and Properties of Dark Matter
Sean Fraser, Andi Hektor, Gert Hütsi +8
The recently claimed anomaly in the measurement of the 21 cm hydrogen absorption signal by EDGES at , if cosmological, requires the existence of new physics. The possible…
Modifying dark matter indirect detection signals by thermal effects at freeze-out
Andi Hektor, Kristjan Kannike, Ville Vaskonen
We present an extension of the Standard Model, containing a fermion dark matter candidate and two real scalar singlets, where the observed dark matter abundance is produced via fre…
