Highlights from the Telescope Array

EPJ Web of Conferences, 2016
The Telescope Array measures the properties of ultra high energy cosmic ray induced extensive air showers. We do this using a variety of techniques including an array of scintillator detectors to sample the footprint of the air shower when it reaches the

Improved Constraints on the 21 cm EoR Power Spectrum and the X-Ray Heating of the IGM with HERA Phase I Observations

The Astrophysical Journal, 2023
We report the most sensitive upper limits to date on the 21 cm epoch of reionization power spectrum using 94 nights of observing with Phase I of the Hydrogen Epoch of Reionization Array (HERA).

Cosmic coding and transfer for ultra high security near-field communications

iScience, 2023
Summary: By using true random number (TRN) generators, encoding with the highest security can be realized. However, a completely secure strategy to transfer these TRNs has not yet been devised.

DEVELOPMENT OF THE COSMIC RAY TECHNIQUES

Le Journal de Physique Colloques, 1982
A close relationship exists between the advances of cosmic-ray physics and technical developments. Thus the development of highly sensitive ionization chambers, eventually to become self-recording instruments, was an essential prerequisite of the observations which first suggested, then proved the extraterrestrial origin of the radiation. The invention

Measurement of the flux of ultra high energy cosmic rays by the stereo technique

Astroparticle Physics, 2009
The High Resolution Fly's Eye experiment has measured the flux of ultrahigh energy cosmic rays using the stereoscopic air fluorescence technique. The HiRes experiment consists of two detectors that observe cosmic ray showers via the fluorescence light they emit. HiRes data can be analyzed in monocular mode, where each detector is treated separately, or

AugerNext: innovative research studies for the next generation ground-based ultra-high energy cosmic ray experiment

EPJ Web of Conferences, 2013
The findings so far of the Pierre Auger Observatory and also of the Telescope Array define the requirements for a possible next generation experiment: it needs to be considerably increased in size, it needs a better sensitivity to composition, and it ...

Femtosecond‐Laser Nanocavitation Regenerates SERS‐Active Plasmonic Nanogaps for Longitudinal Molecular Sensing at Biointerfaces

Advanced Science, EarlyView.
A regenerative molecular sensing platform that co‐localizes surface‐enhanced Raman spectroscopy (SERS) sensing and nanocavitation‐based actuation. Femtosecond‐laser triggered nanocavitation produces thermomechanical forces to locally regenerate SERS‐active nanogaps in protein‐rich biofluids while preserving optical performance.
