Constraining Primordial Black Holes with Dwarf Galaxy Heating
Philip Lu, Volodymyr Takhistov, Graciela B. Gelmini +3
Black holes formed in the early universe, prior to the formation of stars, can exist as dark matter and also contribute to the black hole merger events observed in gravitational wa…
New X-ray bound on density of primordial black holes
Yoshiyuki Inoue, Alexander Kusenko
We set a new upper limit on the abundance of primordial black holes (PBH) based on existing X-ray data. PBH interactions with interstellar medium should result in significant fluxe…
Upper Bound on the First Star Formation History
Yoshiyuki Inoue, Yasuyuki T. Tanaka, Grzegorz M. Madejski +1
Our understanding of the nature of the extragalactic background light (EBL) has improved with the recent development of gamma-ray observation techniques. An open subject in the con…
Probing the Cosmic X-ray and MeV Gamma-ray Background Radiation through the Anisotropy
Yoshiyuki Inoue, Kohta Murase, Grzegorz M. Madejski +1
While the cosmic soft X-ray background is very likely to originate from individual Seyfert galaxies, the origin of the cosmic hard X-ray and MeV gamma-ray background is not fully u…
Potential of EBL and cosmology studies with the Cherenkov Telescope Array
Daniel Mazin, Martin Raue, Bagmeet Behera +4
Very high energy (VHE, E >100 GeV) gamma-rays are absorbed via interaction with low-energy photons from the extragalactic background light (EBL) if the involved photon energies are…
Extragalactic Background Light from Hierarchical Galaxy Formation: Gamma-ray Attenuation up to the Epoch of Cosmic Reionization and the First Stars
Yoshiyuki Inoue, Susumu Inoue, Masakazu A. R. Kobayashi +3
We present a new model of the extragalactic background light (EBL) and corresponding gamma-gamma opacity for intergalactic gamma-ray absorption from z = 0 up to z = 10, based on a…
Revisiting the Cosmic Star Formation History: Caution on the Uncertainties in Dust Correction and Star Formation Rate Conversion
Masakazu A. R. Kobayashi, Yoshiyuki Inoue, Akio K. Inoue
The cosmic star formation rate density (CSFRD) has been observationally investigated out to redshift z~10. However, most of theoretical models for galaxy formation underpredict the…
