Boson stars in massless and massive scalar-tensor gravity

Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Tamara Evstafyeva, Roxana Rosca-Mead, Ulrich Sperhake, Bernd Brugmann, | Summary: We study phenomenological features and stability of boson stars in massless and massive scalar-tensor theory of gravity with Damour-Esposito-Farese coupling. This coupling between the tensor and scalar sectors of the theory leads to a phenomenon called spontaneous […]

A surprisingly high number of dual active galactic nuclei in the early Universe

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Michele Perna, Santiago Arribas, Isabella Lamperti, Chiara Circosta, Elena Bertola | Summary: Merger events can trigger gas accretion onto supermassive black holes (SMBHs) sitting at the centre of galaxies, and form close pairs of active galactic nuclei (AGN). The fraction of AGN in pairs gives key information […]

GA-NIFS: A high number of dual AGN at z~3

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Michele Perna, Santiago Arribas, Isabella Lamperti, Chiara Circosta, Elena Bertola | Summary: Merger events can trigger gas accretion onto supermassive black holes (SMBHs) located at the centre of galaxies, and form close pairs of AGN. The fraction of AGN in pairs offers critical insights into the dynamics […]

The formation and cosmic evolution of dust in the early Universe. I. Dust sources

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Raffaella Schneider, Roberto Maiolino, , , | Summary: Dust-obscured star formation has dominated the cosmic history of star formation since z = 4. However, the recent finding of significant amount of dust in galaxies out to z = 8 has opened the new frontier of investigating the […]

Manifestly covariant variational principle for gauge theories of gravity

Kavli Affiliate: Anthony Lasenby | First 5 Authors: Michael Hobson, Anthony Lasenby, Will Barker, , | Summary: A variational principle for gauge theories of gravity is presented, which maintains manifest covariance under the symmetries to which the action is invariant, throughout the calculation of the equations of motion and conservation laws. This is performed by […]

GA-NIFS: Early-stage feedback in a heavily obscured AGN at $z=4.76$

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Eleonora Parlanti, Stefano Carniani, Hannah Übler, Giacomo Venturi, Francesco D’Eugenio | Summary: Dust-obscured galaxies are thought to represent an early evolutionary phase of massive galaxies in which the active galactic nucleus (AGN) is still deeply buried in significant amounts of dusty material and its emission is strongly […]
