FlexKnot and Gaussian Process for 21 cm global signal analysis and foreground separation
Kavli Affiliate: George Efstathiou | First 5 Authors: Stefan Heimersheim, Leiv Rønneberg, Henry Linton, Filippo Pagani, Anastasia Fialkov | Summary: The cosmological 21 cm signal is one of the most promising avenues to study the Epoch of Reionization. One class of experiments aiming to detect this signal is global signal experiments measuring the sky-averaged 21 […]

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 […]
