Exploring the high-redshift PBH-CDM Universe: early black hole seeding, the first stars and cosmic radiation backgrounds
Nico Cappelluti, Günther Hasinger, Priyamvada Natarajan
We explore the observational implications of a model in which primordial black holes (PBHs) with a broad birth mass function ranging in mass from a fraction of a solar mass to $\si…
Spectral Properties Of Populations Behind The Coherence In Spitzer Near-Infrared And Chandra X-Ray Backgrounds
Yanxia Li, Nico Cappelluti, Günther Hasinger +3
We study the coherence of the near-infrared and X-ray background fluctuations and the X-ray spectral properties of the sources producing it. We use data from multiple Spitzer and C…
An observational link between AGN Eddington ratio and [NII]λ6583/Ha at 0.6<z<1.7
Kyuseok Oh, Yoshihiro Ueda, Masayuki Akiyama +4
We present an observed relationship between Eddington ratio (λEdd) and optical narrow-emission-line ratio ([N II]λ6583/Hα) of X-ray-selected broad-line active galactic nuclei (AGN)…
Electromagnetic probes of primordial black holes as dark matter
Y. Ali-Haimoud, S. Clesse, J. Garcia-Bellido +91
The LIGO discoveries have rekindled suggestions that primordial black holes (BHs) may constitute part to all of the dark matter (DM) in the Universe. Such suggestions came from 1)…
Populations behind the source-subtracted cosmic infrared background anisotropies
A. Kashlinsky, R. G. Arendt, M. Ashby +27
While the upcoming telescopes will reveal correspondingly fainter, more distant galaxies, a question will persist: what more is there that these telescopes cannot see? One answer i…
Probing the cross-power of unresolved cosmic infrared and X-ray backgrounds with upcoming space missions
A. Kashlinsky, R. G. Arendt, N. Cappelluti +4
The source-subtracted cosmic infrared background (CIB) fluctuations uncovered in deep Spitzer data cannot be explained by known galaxy populations and appear strongly coherent with…
