How can we finally see the first light? Status and perspective in the search for Population III stars

Alessandra Venditti, Daniel Schaerer, Erik Zackrisson +28

Finding the first (Population III or Pop III) stars is one of the fundamental quests of astronomy, aiming to deliver the missing link in how stars form at early cosmic times. Yet t…

The role of major mergers in triggering super-Eddington accretion

Riccardo Caleno, Tommaso Zana, Raffaella Schneider +6

JWST observations have opened a new era in the exploration of the high-redshift Universe, revealing black holes (BHs) with masses of several million solar masses already at ,…

BlackTHUNDER: Evidence of three massive black holes in a z~5 galaxy

Hannah Übler, Giovanni Mazzolari, Roberto Maiolino +41

We present observational evidence of three massive, accreting black holes (BHs) in the z=5.0167 galaxy J0148-4214 from JWST/NIRSpec-IFU spectroscopy. The BHs are revealed through b…

You can't see me: Super-Eddington growth hindering X-ray detection in high-z broad-line active galactic nuclei

Alessandro Trinca, Alessandro Lupi, Francesco Haardt +1

We revisit black hole mass estimates for high-redshift broad-line active galactic nuclei (AGNs) discovered with JWST by jointly analysing their broad emission lines and their syste…

The LISA Astrophysics MBHcatalogues Project: A comparison of predictions of simulated massive black hole binaries

David Izquierdo-Villalba, Melanie Habouzit, Matteo Bonetti +67

In the hierarchical paradigm of galaxy formation, central massive black holes (MBHs) are expected to coalesce after the merger of their host galaxies. One of the main goals of the…

Gravitational Waves from the Cosmic Dawn: Tracing Cosmic Black Hole Binaries with ET, LGWA and LISA

Nazanin Davari, Rosa Valiante, Alessandro Trinca +8

Next generation detectors, such as LISA, LGWA, and ET will, for the first time, probe the high redshift Universe, offering unique insight into the birth, growth, and dynamics of th…
