Two populations of LIGO-Virgo black holes
Gert Hütsi, Martti Raidal, Ville Vaskonen +1
We analyse the LIGO-Virgo data, including the recently released GWTC-2 dataset, to test a hypothesis that the data contains more than one population of black holes. We perform a ma…
Dark matter of any spin -- an effective field theory and applications
Juan Carlos Criado, Niko Koivunen, Martti Raidal +1
We develop an effective field theory of a generic massive particle of any spin and, as an example, apply this to study higher-spin dark matter (DM). Our formalism does not introduc…
Minkowski space in gravity
Jose Beltran Jimenez, Alexey Golovnev, Tomi Koivisto +1
The full set of solutions of gravity with the Minkowski metric is considered in this note. At the 4-th order in perturbations around the trivial tetrad solution, a new mode…
Boosting Ultraviolet Freeze-in in NO Models
Nicolás Bernal, Javier Rubio, Hardi Veermäe
We present a novel UV freeze-in mechanism for enhancing the dark matter abundance in cosmologies where inflation is followed by an epoch dominated by a fluid stiffer than radiation…
Implications of Milky Way Substructures for the Nature of Dark Matter
María Benito, Juan Carlos Criado, Gert Hütsi +2
We study how the indirect observation of dark matter substructures in the Milky Way, using recent stellar stream studies, translates into constraints for different dark matter mode…
