Diversity in density profiles of self-interacting dark matter satellite halos
Felix Kahlhoefer, Manoj Kaplinghat, Tracy R. Slatyer +1
We present results from N-body simulations of self-interacting dark matter (SIDM) subhalos, which could host ultra-faint dwarf spheroidal galaxies, inside a Milky-Way-like main hal…
Enhanced n-body annihilation of dark matter and its indirect signatures
Mohammad Hossein Namjoo, Tracy R. Slatyer, Chih-Liang Wu
We examine the possible indirect signatures of dark matter annihilation processes with a non-standard scaling with the dark matter density, and in particular the case where more th…
Early-Universe Constraints on Dark Matter-Baryon Scattering and their Implications for a Global 21cm Signal
Tracy R. Slatyer, Chih-Liang Wu
We present and compare several cosmological constraints on the cross section for elastic scattering between dark matter (DM) and baryons, for cross sections with a range of power-l…
Stellar Wakes from Dark Matter Subhalos
Malte Buschmann, Joachim Kopp, Benjamin R. Safdi +1
We propose a novel method utilizing stellar kinematic data to detect low-mass substructure in the Milky Way's dark matter halo. By probing characteristic wakes that a passing dark…
Constraining a Thin Dark Matter Disk with Gaia
Katelin Schutz, Tongyan Lin, Benjamin R. Safdi +1
If a component of the dark matter has dissipative interactions, it could collapse to form a thin dark disk in our Galaxy that is coplanar with the baryonic disk. It has been sugges…
General Constraints on Dark Matter Decay from the Cosmic Microwave Background
Tracy R. Slatyer, Chih-Liang Wu
Precise measurements of the temperature and polarization anisotropies of the cosmic microwave background can be used to constrain the annihilation and decay of dark matter. In this…
Atomic ionization by sterile-to-active neutrino conversion and constraints on dark matter sterile neutrinos with germanium detectors
Jiunn-Wei Chen, Hsin-Chang Chi, Shin-Ted Lin +5
The transition magnetic moment of a sterile-to-active neutrino conversion gives rise to not only radiative decay of a sterile neutrino, but also its non-standard interaction (NSI)…
Electronic and nuclear contributions in sub-GeV dark matter scattering: A case study with hydrogen
Jiunn-Wei Chen, Hsin-Chang Chi, C. -P. Liu +2
Scattering of sub-GeV dark matter (DM) particles with hydrogen atoms is studied in this paper. The interactions of DM with electrons and nucleons are both included and formulated i…
Constraining neutrino electromagnetic properties by germanium detectors
Jiunn-Wei Chen, Hsin-Chang Chi, Keh-Ning Huang +6
The electromagnetic properties of neutrinos, which are either trivial or negligible in the context of the Standard Model, can probe new physics and have significant implications in…
Constraints on millicharged neutrinos via analysis of data from atomic ionizations with germanium detectors at sub-keV sensitivities
Jiunn-Wei Chen, Hsin-Chang Chi, Hau-Bin Li +5
With the advent of detectors with sub-keV sensitivities, atomic ionization has been identified as a promising avenue to probe possible neutrino electromagnetic properties. The inte…
Atomic ionization of germanium due to neutrino magnetic moments
Jiunn-Wei Chen, Hsin-Chang Chi, Keh-Ning Huang +6
An ab initio calculation of atomic ionization of germanium (Ge) by neutrinos was carried out in the framework of multiconfiguration relativistic random phase approximation. The mai…
Ionization of hydrogen by neutrino magnetic moment, relativistic muon, and WIMP
Jiunn-Wei Chen, C. -P. Liu, Chien-Fu Liu +1
We studied the ionization of hydrogen by scattering of neutrino magnetic moment, relativistic muon, and weakly-interacting massive particle with a QED-like interaction. Analytic re…
