Direct Measurement of the Cosmic-Ray Carbon and Oxygen Spectra from 10 GeV to 2.2 TeV with the Calorimetric Electron Telescope on the International Space Station
O. Adriani, Y. Akaike, K. Asano +81
In this paper, we present the measurement of the energy spectra of carbon and oxygen in cosmic rays based on observations with the Calorimetric Electron Telescope (CALET) on the In…
Spins of primordial black holes formed in the radiation-dominated phase of the universe: first-order effect
Tomohiro Harada, Chul-Moon Yoo, Kazunori Kohri +2
The standard deviation of the initial values of the nondimensional Kerr parameter of primordial black holes (PBHs) formed in the radiation-dominated phase of the universe i…
Sensitivity of the Cherenkov Telescope Array for probing cosmology and fundamental physics with gamma-ray propagation
The Cherenkov Telescope Array Consortium, :, H. Abdalla +496
The Cherenkov Telescope Array (CTA), the new-generation ground-based observatory for -ray astronomy, provides unique capabilities to address significant open questions in astrop…
Solar-Mass Primordial Black Holes Explain NANOGrav Hint of Gravitational Waves
Kazunori Kohri, Takahiro Terada
The NANOGrav collaboration for the pulsar timing array (PTA) observation recently announced evidence of an isotropic stochastic process, which may be the first detection of the sto…
Abundance of Primordial Black Holes in Peak Theory for an Arbitrary Power Spectrum
Chul-Moon Yoo, Tomohiro Harada, Shin'ichi Hirano +1
We modify the procedure to estimate PBH abundance proposed in arXiv:1805.03946 so that it can be applied to a broad power spectrum such as the scale-invariant flat power spectrum.…
Sensitivity of the Cherenkov Telescope Array to a dark matter signal from the Galactic centre
The Cherenkov Telescope Array Consortium, :, A. Acharyya +449
We provide an updated assessment of the power of the Cherenkov Telescope Array (CTA) to search for thermally produced dark matter at the TeV scale, via the associated gamma-ray sig…
