Black hole spin evolution across cosmic time from the NewHorizon simulation
Ricarda S. Beckmann, Yohan Dubois, Marta Volonteri +8
Astrophysical black holes (BHs) have two fundamental properties: mass and spin. While the mass-evolution of BHs has been extensively studied, much less work has been done on predic…
Searching for the Highest-z Dual AGN in the Deepest Chandra Surveys
Brandon Sandoval, Adi Foord, Steven W. Allen +9
We present an analysis searching for dual AGN among 62 high-redshift () X-ray sources selected from publicly available deep Chandra fields. We aim to quantify the fr…
Multimessenger study of merging massive black holes in the OBELISK simulation: gravitational waves, electromagnetic counterparts, and their link to galaxy and black hole populations
C. A. Dong-Páez, M. Volonteri, R. S. Beckmann +5
Massive black-hole (BH) mergers are predicted to be powerful sources of low-frequency gravitational waves (GWs). Coupling the detection of GWs with an electromagnetic (EM) detectio…
Cosmic-ray diffusion and the multi-phase interstellar medium in a dwarf galaxy. I. Large-scale properties and -ray luminosities
A. Nuñez-Castiñeyra, I. A. Grenier, F. Bournaud +3
Dynamically, cosmic rays with energies above about one GeV/nucleon may be important agents of galaxy evolution. Their pressures compare with the thermal and magnetic ones impacting…
Propagation of ultrahigh energy nuclei in clusters of galaxies: resulting composition and secondary emissions
K. Kotera, D. Allard, K. Murase +4
We study the survival of ultrahigh energy nuclei injected in clusters of galaxies, as well as their secondary neutrino and photon emissions, using a complete numerical propagation…
