Ly$α$ emission in galaxies at $zsimeq5-6$: new insight from JWST into the statistical distributions of Ly$α$ properties at the end of reionization

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Mengtao Tang, Daniel P. Stark, Richard S. Ellis, Fengwu Sun, Michael Topping | Summary: JWST has recently sparked a new era of Ly$alpha$ spectroscopy, delivering the first measurements of the Ly$alpha$ escape fraction and velocity profile in typical galaxies at $zsimeq6-10$. These observations offer new prospects for […]

Understanding spectral artefacts in SKA-LOW 21-cm cosmology experiments: the impact of cable reflections

Kavli Affiliate: George Efstathiou | First 5 Authors: Oscar Sage David O’Hara, Fred Dulwich, Eloy de Lera Acedo, Jiten Dhandha, Thomas Gessey-Jones | Summary: The Cosmic Dawn marks the first star formations and preceded the Epoch-of-Reionization, when the Universe underwent a fundamental transformation propelled by the radiation from these first stars and galaxies. Interferometric 21-cm […]

The role of environment and AGN feedback in quenching local galaxies: Comparing cosmological hydrodynamical simulations to the SDSS

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Paul H. Goubert, Asa F. L. Bluck, Joanna M. Piotrowska, Roberto Maiolino, | Summary: We present an analysis of the quenching of local observed and simulated galaxies, including an investigation of the dependence of quiescence on both intrinsic and environmental parameters. We apply an advanced machine learning […]

The stellar Fundamental Metallicity Relation: the correlation between stellar mass, star-formation rate and stellar metallicity

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Tobias J. Looser, Francesco D’Eugenio, Joanna M. Piotrowska, Francesco Belfiore, Roberto Maiolino | Summary: We present observational evidence for a stellar Fundamental Metallicity Relation (FMR), a smooth relation between stellar mass, star-formation rate (SFR) and the light-weighted stellar metallicity of galaxies (analogous to the well-established gas-phase FMR). […]

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 […]
