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…
Horizonless ultracompact objects and dark matter in quadratic gravity
Alberto Salvio, Hardi Veermäe
We show that in quadratic gravity sufficiently light objects must be horizonless and construct explicit analytic examples of horizonless ultracompact objects (UCOs), which are more…
Small-scale structure of primordial black hole dark matter and its implications for accretion
Gert Hütsi, Martti Raidal, Hardi Veermäe
Primordial black hole (PBH) dark matter (DM) nonlinear small-scale structure formation begins before the epoch of recombination due to large Poisson density fluctuations. Those sma…
