Input optics systems of the KAGRA detector during O3GK
T. Akutsu, M. Ando, K. Arai +246
KAGRA, the underground and cryogenic gravitational-wave detector, was operated for its solo observation from February 25th to March 10th, 2020, and its first joint observation with…
First results from a second generation galactic axion experiment
C. Hagmann, D. Kinion, W. Stoeffl +15
We report first results from a large scale search for dark matter axions. The experiment probes axion masses of 1.3-13 micro-eV at a sensitivity which is about 50 times higher than…
Symmetry Breaking in Haloscope Microwave Cavities
I. Stern, N. Sullivan, D. Tanner
Axion haloscope detectors use microwave cavities permeated by a magnetic field to resonate photons that are converted from axions due to the inverse Primakoff effect. The sensitivi…
The Gravitational Universe
The eLISA Consortium, :, P. Amaro Seoane +158
The last century has seen enormous progress in our understanding of the Universe. We know the life cycles of stars, the structure of galaxies, the remnants of the big bang, and hav…
Quantization leading to a natural flattening of the axion potential
J. Alexandre, D. Tanner
Starting from the general cosine form for the axion effective potential, we quantize the axion and show that the result is described by a naturally flat potential, if interactions…
Results from a High-Sensitivity Search for Cosmic Axions
C. Hagmann, D. Kinion, W. Stoeffl +13
We report the first results of a high-sensitivity (10^{-23} Watt) search for light halo axions through their conversion to microwave photons. At 90 percent confidence we exclude a…
A 2nd generation cosmic axion experiment
C. Hagmann, W. Stoeffl, K. van Bibber +11
An experiment is described to detect dark matter axions trapped in the halo of our galaxy. Galactic axions are converted into microwave photons via the Primakoff effect in a static…
