The Structure of cold dark matter halos [PDF]
, 1995 High resolution N-body simulations show that the density profiles of dark matter halos formed in the standard CDM cosmogony can be fit accurately by scaling a simple “universal” profile.

Dark Matter Search Results from a One Ton-Year Exposure of XENON1T. [PDF]
Physical Review Letters, 2018 We report on a search for weakly interacting massive particles (WIMPs) using 278.8 days of data collected with the XENON1T experiment at LNGS. XENON1T utilizes a liquid xenon time projection chamber with a fiducial mass of (1.30±0.01) ton, resulting in ...

SENSEI: Direct-Detection Results on sub-GeV Dark Matter from a New Skipper CCD. [PDF]
Physical Review Letters, 2020 We present the first direct-detection search for sub-GeV dark matter using a new ∼2-gram high-resistivity Skipper CCD from a dedicated fabrication batch that was optimized for dark matter searches.

Quasi-Periodic Pulsations in an M-Class Solar Flare
Universe, 2023 We have studied the quasi-periodic pulsations (QPPs) of the M2.3 flare that occurred in the active region NOAA 12172 on 23 September 2014. Through the fast Fourier transform (FFT) method, we decompose the flare light curves into fast- and slowly-varying ...

Searching for Dark Matter with a Superconducting Qubit. [PDF]
Physical Review Letters, 2020 Detection mechanisms for low mass bosonic dark matter candidates, such as the axion or hidden photon, leverage potential interactions with electromagnetic fields, whereby the dark matter (of unknown mass) on rare occasion converts into a single photon ...

A GeV-TeV particle component and the barrier of cosmic-ray sea in the Central Molecular Zone
Nature Communications, 2021 Galactic center is one of the most important cosmic-ray sources. Here, the authors show GeV-TeV cosmic ray density in the central molecular zone is lower than the cosmic ray sea component, suggesting presence of high energy particle accelerator at the ...

Has the origin of the third-family fermion masses been determined?
Journal of High Energy Physics, 2021 Precision measurements of the Higgs couplings are, for the first time, directly probing the mechanism of fermion mass generation. The purpose of this work is to determine to what extent these measurements can distinguish between the tree-level mechanism ...

Modified Dark Matter: Relating Dark Energy, Dark Matter and Baryonic Matter [PDF]
, 2017 Modified dark matter (MDM) is a phenomenological model of dark matter, inspired by gravitational thermodynamics. For an accelerating Universe with positive cosmological constant ($\Lambda$), such phenomenological considerations lead to the emergence of a

Non-cold dark matter from primordial black hole evaporation [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 Dark matter coupled solely gravitationally can be produced through the decay of primordial black holes in the early universe. If the dark matter is lighter than the initial black hole temperature, it could be warm enough to be subject to structure ...

Constraining Dark Boson Decay Using Neutron Stars
Universe, 2023 Inspired by the well-known anomaly in the lifetime of the neutron, we investigated its consequences inside neutron stars. We first assessed the viability of the neutron decay hypothesis suggested by Fornal and Grinstein within neutron stars, in terms of ...
