Cosmic Microwave Background Signatures from Current-carrying Cosmic Strings

Kavli Affiliate: E. P. S. Shellard | First 5 Authors: I. Yu. Rybak, C. J. A. P. Martins, Patrick Peter, E. P. S. Shellard, | Summary: We continue our studies of the evolution and cosmological consequences of current-carrying cosmic string networks, described by a charge-velocity-dependent one scale (CVOS) model. We present a detailed calculation of […]

No evidence of AGN features in the nuclei of Arp 220 from JWST/NIRSpec IFS

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Michele Perna, Santiago Arribas, Isabella Lamperti, Miguel Pereira-Santaella, Lorenzo Ulivi | Summary: Arp 220 is the nearest ULIRG; it shows evidence of 100 pc-scale molecular outflows likely connected with galaxy-scale outflows traced by ionised and neutral gas. The two highly obscured nuclei of Arp 220 are the […]

Spatially resolved emission lines in galaxies at $4leq z < 10$ from the JADES survey: evidence for enhanced central star formation

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Roberta Tripodi, Francesco D’Eugenio, Roberto Maiolino, Mirko Curti, Jan Scholtz | Summary: We present the first statistical investigation of spatially resolved emission-line properties in a sample of 63 low-mass galaxies at $4leq z<10$, using JWST/NIRSpec MSA data from the JWST Advanced Deep Extragalactic (JADES) survey focusing on […]

The NIRSpec Wide GTO Survey

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Michael V. Maseda, Anna de Graaff, Marijn Franx, Hans-Walter Rix, Stefano Carniani | Summary: The Near-infrared Spectrograph (NIRSpec) on the James Webb Space Telescope is uniquely suited to studying galaxies in the distant Universe with its combination of multi-object capabilities and sensitivity over a large range in […]

A dormant, overmassive black hole in the early Universe

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Ignas Juodžbalis, Roberto Maiolino, William M. Baker, Sandro Tacchella, Jan Scholtz | Summary: Recent observations have found a large number of supermassive black holes already in place in the first few hundred million years after Big Bang. The channels of formation and growth of these early, massive […]

The nature of diffuse ionised gas in star-forming galaxies

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 […]

The FLAMINGO simulation view of cluster progenitors observed in the epoch of reionization with JWST

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 […]

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 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 […]
