Formation of inflaton halos after inflation
Benedikt Eggemeier, Jens C. Niemeyer, Richard Easther
The early Universe may have passed through an extended period of matter-dominated expansion following inflation and prior to the onset of radiation domination. Sub-horizon density…
AxioNyx: Simulating Mixed Fuzzy and Cold Dark Matter
Bodo Schwabe, Mateja Gosenca, Christoph Behrens +2
The distinctive effects of fuzzy dark matter are most visible at non-linear galactic scales. We present the first simulations of mixed fuzzy and cold dark matter, obtained with an…
Robust posterior inference when statistically emulating forward simulations
Grigor Aslanyan, Richard Easther, Nathan Musoke +1
Scientific analyses often rely on slow, but accurate forward models for observable data conditioned on known model parameters. While various emulation schemes exist to approximate…
The Distribution of Vacua in Random Landscape Potentials
Lerh Feng Low, Shaun Hotchkiss, Richard Easther
Landscape cosmology posits the existence of a convoluted, multidimensional, scalar potential -- the "landscape" -- with vast numbers of metastable minima. Random matrices and rando…
Prospects for Fundamental Physics with LISA
Enrico Barausse, Emanuele Berti, Thomas Hertog +318
In this paper, which is of programmatic rather than quantitative nature, we aim to further delineate and sharpen the future potential of the LISA mission in the area of fundamental…
