Electroweak symmetric dark matter balls

Journal 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.

Calibration Monitor for Dark Energy Experiments [PDF]

, 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 ...

The Hobby–Eberly Telescope Dark Energy Experiment (HETDEX) Survey Design, Reductions, and Detections*

The Astrophysical Journal, 2021
Abstract We describe the survey design, calibration, commissioning, and emission-line detection algorithms for the Hobby–Eberly Telescope Dark Energy Experiment (HETDEX). The goal of HETDEX is to measure the redshifts of over a million Lyα emitting galaxies between 1.88 < z < 3.52, in a 540 deg2 area encompassing a comoving volume ...

Relic abundance of dark photon dark matter

Physics 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

Proposed Dark Energy Experiment using Fullerenes

Physics Procedia, 2012
AbstractA dark energy experiment is proposed, based on the dark energy research funded by the U.S. Department of Energy (DOE), Office of Science. The experiment would replicate the conditions of deep space; i.e., ultra-vacuum, isolation from the Earth's magnetic field, cryogenic temperatures, and an isotropic environment.

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

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

Proceedings 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.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
