Kavli Affiliate: Roberto Maiolino | First 5 Authors: William McClymont, Sandro Tacchella, Aaron Smith, Rahul Kannan, Roberto Maiolino | Summary: We present an analysis of the diffuse ionised gas (DIG) in a high-resolution simulation of an isolated Milky Way-like galaxy, incorporating on-the-fly radiative transfer and non-equilibrium thermochemistry. We utilise the Monte-Carlo radiative transfer code COLT […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Seunghwan Lim, Sandro Tacchella, Joop Schaye, Matthieu Schaller, Jakob M. Helton | Summary: Motivated by the recent JWST discovery of galaxy overdensities during the Epoch of Reionzation, we examine the physical properties of high-$z$ protoclusters and their evolution using the FLAMINGO simulation suite. We investigate the impact […]
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 Lya spectroscopy, delivering the first measurements of the Lya escape fraction and velocity profile in typical galaxies at z~6-10. These observations offer new prospects for […]
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 […]
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 […]
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). […]
Kavli Affiliate: E. P. S. Shellard | First 5 Authors: Yoann L. Launay, Gerasimos I. Rigopoulos, E. P. S. Shellard, , | Summary: We provide a formulation of Stochastic Inflation in full general relativity that goes beyond the slow-roll and separate universe approximations. We show how gauge invariant Langevin source terms can be obtained for […]
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 […]
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 […]
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 […]
