FLAMINGO: The thermal history of the Universe from tSZ effect cross-correlations and its dependencies on cosmology and baryon physics
Jaime Salcido, Tianyi Yang, Ian G. McCarthy +9
The cross-correlation between tracers of large-scale structure, such as galaxies or quasars, and the thermal Sunyaev-Zel'dovich (tSZ) signal yields a measure of the bias-weighted m…
Slow neutrinos: non-linearity and momentum-space emulation
Amol Upadhye, Yin Li
Recent cosmological bounds on the sum of neutrino masses, M_nu = sum m_nu, are in tension with laboratory oscillation experiments, making cosmological tests of neutrino free-stream…
One trick to treat them all: SuperEasy linear response for any hot dark matter in -body simulations
Giovanni Pierobon, Markus R. Mosbech, Amol Upadhye +1
We generalise the SuperEasy linear response method, originally developed to describe massive neutrinos in cosmological -body simulations, to any hot dark matter (HDM) species wi…
Everything hot everywhere all at once: Neutrinos and hot dark matter as a single effective species
Amol Upadhye, Markus R. Mosbech, Giovanni Pierobon +1
Observational cosmology is rapidly closing in on a measurement of the sum M_nu of neutrino masses, at least in the simplest cosmologies, while opening the door to probes of non-sta…
