Constraining the clustering and 21-cm signature of radio galaxies at cosmic dawn

Kavli Affiliate: George Efstathiou | First 5 Authors: Sudipta Sikder, Rennan Barkana, Anastasia Fialkov, , | Summary: The efficiency of radio emission is an important unknown parameter of early galaxies at cosmic dawn, as models with high efficiency have been shown to modify the cosmological 21-cm signal substantially, deepening the absorption trough and boosting the […]

Ly$α$ emission as a sensitive probe of feedback-regulated LyC escape from dwarf galaxies

Kavli Affiliate: Debora Sijacki | First 5 Authors: Yuxuan Yuan, Sergio Martin-Alvarez, Martin G. Haehnelt, Thibault Garel, Debora Sijacki | Summary: Ly$alpha$ emission is an exceptionally informative tracer of the life cycle of evolving galaxies and the escape of ionising photons. However, theoretical studies of Ly$alpha$ emission are often limited by insufficient numerical resolution, incomplete […]

JADES: Rest-frame UV-to-NIR Size Evolution of Massive Quiescent Galaxies from Redshift z=5 to z=0.5

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Zhiyuan Ji, Christina C. Williams, Katherine A. Suess, Sandro Tacchella, Benjamin D. Johnson | Summary: We present the UV-to-NIR size evolution of a sample of 161 quiescent galaxies (QGs) with $M_*>10^{10}M_odot$ over $0.5<z<5$. With deep multi-band NIRCam images in GOODS-South from JADES, we measure the effective radii […]

A unified accretion disc model for supermassive black holes in galaxy formation simulations: method and implementation

Kavli Affiliate: Debora Sijacki | First 5 Authors: Sophie Koudmani, Rachel S. Somerville, Debora Sijacki, Martin A. Bourne, Yan-Fei Jiang | Summary: It is well established that supermassive black hole (SMBH) feedback is crucial for regulating the evolution of massive, if not all, galaxies. However, modelling the interplay between SMBHs and their host galaxies is […]

GA-NIFS: JWST discovers an offset AGN 740 million years after the Big Bang

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Hannah Übler, Roberto Maiolino, Pablo G. Pérez-González, Francesco D’Eugenio, Michele Perna | Summary: A surprising finding of recent studies is the large number of Active Galactic Nuclei (AGN) associated with moderately massive black holes ($rm log(M_bullet/M_odot)sim 6-8$), in the first billion years after the Big Bang ($z>5$).
