Enlightening the dark ages with dark matter
Katie Short, José Luis Bernal, Alvise Raccanelli +2
Constraints on dark matter annihilation or decay offer unique insights into the nature of dark matter. We illustrate how surveys dedicated to detect the highly redshifted 21 cm sig…
Microwave Spectro-Polarimetry of Matter and Radiation across Space and Time
Jacques Delabrouille, Maximilian H. Abitbol, Nabila Aghanim +77
This paper discusses the science case for a sensitive spectro-polarimetric survey of the microwave sky. Such a survey would provide a tomographic and dynamic census of the three-di…
Mapping Large-Scale-Structure Evolution over Cosmic Times
Marta B. Silva, Ely D. Kovetz, Garrett K. Keating +6
This paper outlines the science case for line-intensity mapping with a space-borne instrument targeting the sub-millimeter (microwaves) to the far-infrared (FIR) wavelength range.…
A User's Guide to Extracting Cosmological Information from Line-Intensity Maps
José Luis Bernal, Patrick C. Breysse, Héctor Gil-Marín +1
Line-intensity mapping (LIM) provides a promising way to probe cosmology, reionization and galaxy evolution. However, its sensitivity to cosmology and astrophysics at the same time…
The Cosmic Expansion History from Line-Intensity Mapping
José Luis Bernal, Patrick C. Breysse, Ely D. Kovetz
Line-intensity mapping (LIM) of emission from star-forming galaxies can be used to measure the baryon acoustic oscillation (BAO) scale as far back as the epoch of reionization. Thi…
Can Dark Matter be Geometry? A Case Study with Mimetic Dark Matter
Ali Rida Khalifeh, Nicola Bellomo, José Luis Bernal +1
We investigate the possibility of dark matter being a pure geometrical effect, rather than a particle or a compact object, by exploring a specific modified gravity model: mimetic d…
