Impacts of Jets and Winds From Primordial Black Holes
Volodymyr Takhistov, Philip Lu, Kohta Murase +2
Primordial black holes (PBHs) formed in the early Universe constitute an attractive candidate for dark matter. Within the gaseous environment of the interstellar medium, PBHs with…
A Fundamental Plane in X-ray Binary Activity of External Galaxies
Yoshiyuki Inoue, Kiyoto Yabe, Yoshihiro Ueda
We construct a new catalog of extragalactic X-ray binaries (XRBs) by matching the latest Chandra source catalog with local galaxy catalogs. Our XRB catalog contains 4430 XRBs hoste…
Reconstruction of multiple Compton scattering events in MeV gamma-ray Compton telescopes towards GRAMS: the physics-based probabilistic model
Hiroki Yoneda, Hirokazu Odaka, Yuto Ichinohe +19
Aimed at progress in mega-electron volt (MeV) gamma-ray astronomy, which has not yet been well-explored, Compton telescope missions with a variety of detector concepts have been pr…
Spatial variations of magnetic field along active galactic nuclei jets on sub-pc to Mpc scales
Soichiro Ito, Yoshiyuki Inoue, Jun Kataoka
We report the systematic analysis of knots, hotspots, and lobes in 57 active galactic nuclei (AGNs) to investigate the variation of the magnetic field along with the jet from the s…
Cross-match between the latest Swift-BAT and Fermi-LAT catalogs
Naomi Tsuji, Hiroki Yoneda, Yoshiyuki Inoue +4
We report the results of a cross-match study between the hard X-ray and GeV gamma-ray catalogs, by making use of the latest 105-month Swift-BAT and 10-yr Fermi-LAT catalogs, respec…
Gamma-ray and Neutrino Signals from Accretion Disk Coronae of Active Galactic Nuclei
Yoshiyuki Inoue, Dmitry Khangulyan, Akihiro Doi
To explain X-ray spectra of active galactic nuclei (AGN), non-thermal activity in AGN coronae such as pair cascade models has been extensively discussed in the past literature. Alt…
Interstellar Gas Heating by Primordial Black Holes
Volodymyr Takhistov, Philip Lu, Graciela B. Gelmini +3
Interstellar gas heating is a powerful cosmology-independent observable for exploring the parameter space of primordial black holes (PBHs) formed in the early Universe that could c…
Origin of Galactic Spurs: New Insight from Radio/X-ray All-sky Maps
Jun Kataoka, Marino Yamamoto, Yuki Nakamura +5
In this study, we analyze giant Galactic spurs seen in both radio and X-ray all-sky maps to reveal their origins. We discuss two types of giant spurs: one is the brightest diffuse…
