The infrared-luminous progenitors of high-z quasars
Michele Ginolfi, Raffaella Schneider, Rosa Valiante +4
Here we explore the infrared (IR) properties of the progenitors of high-z quasar host galaxies. Adopting the cosmological, data constrained semi-analytic model GAMETE/QSOdust, we s…
The hyperluminous Compton-thick quasar nucleus of the hot DOG W1835+4355 observed by NuSTAR
L. Zappacosta, E. Piconcelli, F. Duras +11
We present a 155ks NuSTAR observation of the hot dust-obscured galaxy (hot DOG) W1835+4355. We extracted spectra from the two NuSTAR detectors and analyzed them jointly wi…
Black holes, gravitational waves and fundamental physics: a roadmap
Leor Barack, Vitor Cardoso, Samaya Nissanke +203
The grand challenges of contemporary fundamental physics---dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem-…
Chasing the observational signatures of seed black holes at z > 7: candidate observability
Rosa Valiante, Raffaella Schneider, Luca Zappacosta +3
Observing the light emitted by the first accreting black holes (BHs) would dramatically improve our understanding of the formation of quasars at z > 6, possibly unveiling the natur…
