Electroweak symmetric dark matter balls

open access: yesJournal of High Energy Physics, 2019
In the simple Higgs-portal dark matter model with a conserved dark matter number, we show that there exists a non-topological soliton state of dark matter.

Resolving XENON excess with decaying cold dark matter

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We propose a decaying cold dark matter model to explain the excess of electron recoil observed at the XENON1T experiment. In this scenario, the daughter dark matter from the parent dark matter decay easily obtains velocity large enough to saturate the ...

Calibration Monitor for Dark Energy Experiments [PDF]

open access: yes, 2009
The goal of this program was to design, build, test, and characterize a flight qualified calibration source and monitor for a Dark Energy related experiment: ACCESS - 'Absolute Color Calibration Experiment for Standard Stars'. This calibration source, the On-board Calibration Monitor (OCM), is a key component of our ACCESS spectrophotometric ...

TESTING THE DARK-ENERGY-DOMINATED COSMOLOGY BY THE SOLAR-SYSTEM EXPERIMENTS [PDF]

open access: yesThe Eleventh Marcel Grossmann Meeting, 2008
According to the recent astronomical data, the most part of energy in the Universe is in the 'dark' form, which is effectively described by Lambda-term in Einstein equations. All arguments in favor of the dark energy were obtained so far from the observational data related to very large (intergalactic) scales.

The GAPS experiment to search for dark matter using low-energy antimatter [PDF]

open access: yesProceedings of 35th International Cosmic Ray Conference — PoS(ICRC2017), 2017
The GAPS experiment is designed to carry out a sensitive dark matter search by measuring low-energy cosmic ray antideuterons and antiprotons. GAPS will provide a new avenue to access a wide range of dark matter models and masses that is complementary to direct detection techniques, collider experiments and other indirect detection techniques.

Search for dark matter candidates and large extra dimensions in events with a jet and missing transverse momentum with the ATLAS detector [PDF]

open access: yes, 2012
ATLAS Collaboration Contributors: Paul Douglas Jackson and Nitesh SoniA search for new phenomena in events with a high-energy jet and large missing transverse momentum is performed using data from proton-proton collisions at √s = 7 TeV with the ATLAS ...

Relic abundance of dark photon dark matter

open access: yesPhysics Letters B, 2020
We present a new mechanism for producing the correct relic abundance of dark photon dark matter over a wide range of its mass, extending down to 10−20eV. The dark matter abundance is initially stored in an axion which is misaligned from its minimum. When

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

open access: yesFEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...
