Together with this article we present a major update 6.3 of DarkSUSY with theĪdded capability of performing general freeze-in calculations, including all The couplings implied by the freeze-in mechanism may be testable at the LHC. We explore in particular the case of small reheating temperatures, for which In the context of Higgs portal models, and provide the most accurateĬalculation to date of the freeze-in abundance of Scalar Singlet dark matter. Strong phase transitions, and we discuss in detail the additional complicationsĪrising in the presence of $s$-channel resonances. Spin statistics of relativistic quantum gases, as well as the temperatureĭependence of dark matter production rates induced by the electroweak and We revisit the formulation of freeze-in production in a way thatįacilitates the inclusion of in-medium corrections like plasma effects and the Technical and computational difficulties when aiming for the same level of To much higher temperatures than in the freeze-out case, implying both Matter production via the freeze-in mechanism, on the other hand, is sensitive Tools readily available that match the observationally required accuracy. Plasma have reached a high level of sophistication, with several numerical Relic density calculations of dark matter freezing out from the primordial Freezing-in a hot bath: resonances, medium effects and phase transitions.- Torsten Bringmann, Saniya Heeba, Felix Kahlhoefer, Kristian Vangsnes.

In this work, we consider the capture of relic The Cosmic Neutrino Background (CNB) is a definite prediction of the standardĬosmological model and its direct discovery would represent a milestone inĬosmology and neutrino physics. Cosmic Neutrino Background Detection in Large-Neutrino-Mass Cosmologies.- James Alvey, Miguel Escudero, Nashwan Sabti, Thomas Schwetz.ISM, nowadays accessible to observations of high and low redshift galaxies. Range of possible studies investigating the physical evolution of the dusty The new implementation described here will open up a wide Of grain properties (both chemical composition and size) on the resultingĬharge distribution. Sight, as a result of radiative transfer effects. Spatial distribution of grain charges is also found, primarily depending on theĮxposure to stellar radiation and strongly varying along different lines of We find that $\sim 13$ % of the total dust mass gets negativelyĬharged, mainly silicate and graphite grains of radius micron. Second, we perform a realistic radiative transfer simulation of a starįorming region extracted from a dusty galaxy evolving in the Epoch of

Series of idealized dusty HII regions created by a single star, in order toĪssess the impact of grain properties on the resulting spatial distribution ofĬharges. We first benchmark the code predictions on a

Introduce a novel implementation of grain charging in the cosmological To its complex physics and the tight dependence on the environment. Importance, this process is still poorly explored in numerical simulations due

Physical evolution of the multiphase interstellar medium (ISM). The presence of charged dust grains is known to have a profound impact on the Information about the redshift distribution from which the GW sources come. This bias is caused by the fundamental degeneracyīetween redshift and $H_0$, and is effectively irreducible without accurate True value even when making optimistic assumptions about the statistical We find that the Hubble constant posterior is in general biased relative to the We study and simulate this "galaxy voting" method to compute $H_0$. Large galaxy survey for example, can be used to accurately constrain the HubbleĬonstant. In the case where no electromagnetic counterparts are identified, it hasīeen proposed that a statistical canvassing of candidate GW hosts, found in a
