Constraining Dark Matter models with extremely distant galaxies
Marco Castellano, Nicola Menci, Andrea Grazian +4
The investigation of distant galaxy formation and evolution is a powerful tool to constrain dark matter scenarios, supporting and in some cases surpassing other astrophysical and e…
A Global Bayesian Analysis of Neutrino Mass Data
Allen Caldwell, Manuel Ettengruber, Alexander Merle +2
We perform a global Bayesian analysis of currently available neutrino data, putting data from oscillation experiments, neutrinoless double beta decay (), and precision cosmol…
"Non-cold" dark matter at small scales: a general approach
Riccardo Murgia, Alexander Merle, Matteo Viel +2
Structure formation at small cosmological scales provides an important frontier for dark matter (DM) research. Scenarios with small DM particle masses, large momenta or hidden inte…
Fundamental physics with the Hubble Frontier Fields: constraining Dark Matter models with the abundance of extremely faint and distant galaxies
Nicola Menci, Alexander Merle, Maximilian Totzauer +4
We show that the measured abundance of ultra-faint lensed galaxies at in the Hubble Frontier Fields (HFF) provides stringent constraints on the parameter space of i) D…
keV Sterile Neutrino Dark Matter from Singlet Scalar Decays: The Most General Case
Johannes König, Alexander Merle, Maximilian Totzauer
We investigate the early Universe production of sterile neutrino Dark Matter by the decays of singlet scalars. All previous studies applied simplifying assumptions and/or studied t…
A White Paper on keV Sterile Neutrino Dark Matter
R. Adhikari, M. Agostini, N. Anh Ky +133
We present a comprehensive review of keV-scale sterile neutrino Dark Matter, collecting views and insights from all disciplines involved - cosmology, astrophysics, nuclear, and par…
Dodelson-Widrow Production of Sterile Neutrino Dark Matter with Non-Trivial Initial Abundance
Alexander Merle, Aurel Schneider, Maximilian Totzauer
The simplest way to create sterile neutrinos in the early Universe is by their admixture to active neutrinos. However, this mechanism, connected to the Dark Matter (DM) problem by…
keV Sterile Neutrino Dark Matter from Singlet Scalar Decays: Basic Concepts and Subtle Features
Alexander Merle, Maximilian Totzauer
We perform a detailed and illustrative study of the production of keV sterile neutrino Dark Matter (DM) by decays of singlet scalars in the early Universe. In the current study we…
Sharp Gamma-ray Spectral Features from Scalar Dark Matter Annihilations
Alejandro Ibarra, Takashi Toma, Maximilian Totzauer +1
The search for sharp features in the gamma-ray spectrum is a promising approach to identify a signal from dark matter annihilations over the astrophysical backgrounds. In this pape…
Higher order dark matter annihilations in the Sun and implications for IceCube
Alejandro Ibarra, Maximilian Totzauer, Sebastian Wild
Dark matter particles captured in the Sun would annihilate producing a neutrino flux that could be detected at the Earth. In some channels, however, the neutrino flux lies in the M…
High-energy neutrino signals from the Sun in dark matter scenarios with internal bremsstrahlung
Alejandro Ibarra, Maximilian Totzauer, Sebastian Wild
We investigate the prospects to observe a high energy neutrino signal from dark matter annihilations in the Sun in scenarios where the dark matter is a Majorana fermion that couple…
