Self-Interacting Neutrinos in Light of Large-Scale Structure Data
Adam He, Rui An, Mikhail M. Ivanov +1
We explore a self-interacting neutrino cosmology in which neutrinos experience a delayed onset of free-streaming. We use the effective field theory of large-scale structure (LSS) t…
What does cosmology tell us about the mass of thermal-relic dark matter?
Rui An, Vera Gluscevic, Erminia Calabrese +1
The presence of light thermally coupled dark matter affects early expansion history and production of light elements during the Big Bang Nucleosynthesis. Specifically, dark matter…
Dark Matter Halos in Interacting Dark Energy Models: Formation History, Density Profile, Spin and Shape
Yun Liu, Shihong Liao, Xiangkun Liu +3
The interacting dark energy (IDE) model, which considers the interaction between dark energy and dark matter, provides a natural mechanism to alleviate the coincidence problem and…
Baryon Acoustic Oscillations from Integrated Neutral Gas Observations: an instrument to observe the 21cm hydrogen line in the redshift range 0.13 z 0.45 -- status update
Carlos A. Wuensche, Elcio Abdalla, Filipe Batoni Abdalla +48
BINGO (BAO from Integrated Neutral Gas Observations) is a unique radio telescope designed to map the intensity of neutral hydrogen distribution at cosmological distances, making th…
Fractional Dark Matter decay: cosmological imprints and observational constraints
Linfeng Xiao, Le Zhang, Rui An +2
If a fraction of the Dark Matter decays into invisible and massless particles (so-called "dark radiation") with the decay rate (or inverse lifetime) ,…
A Fully Self-Consistent Cosmological Simulation Pipeline for Interacting Dark Energy Models
Jiajun Zhang, Rui An, Shihong Liao +3
We devise a fully self-consistent simulation pipeline for the first time to study the interaction between dark matter and dark energy. We perform convergence tests and show that ou…
