We employ the high-redshift suite of FIRE-2 cosmological hydrodynamic zoom-in simulations to investigate the evolution of gas-phase metallicity radial gradients in galaxies in the epoch of reionization (EOR). Our sample ...

We present JWST/NIRSpec PRISM observations of a robust galaxy candidate at z  ≃ 14, selected from pure-parallel NIRCam imaging: PAN-z14-1. The NIRSpec spectrum allows confirmation of this source at ${z}_{{\rm{spec}}}...

We analysed the evolution of the metallicity of the gas with the redshift for a sample of AGNs in a very wide redshift range (0 < z

We study the role of group infall in the assembly and dynamics of galaxy clusters in ΛCDM. We select 10 clusters with virial mass M200 ∼1014 M from the cosmological hydrodynamical simulation Illustris and follow their...

We analyse the radial pressure profiles, the intracluster medium (ICM) clumping factor and the Sunyaev-Zel'dovich (SZ) scaling relations of a sample of simulated galaxy clusters and groups identified in a set of hydrodyn...

In its first 2 yr of operation, the James Webb Space Telescope has enabled the discovery of a surprising number of UV-bright galaxies at z  ∼ 10–14. Their number density is still relatively uncertain, due to cosmic...

Over the last two decades, the Sun has been observed to be depleted in refractory elements as a function of elemental condensation temperature ( T _cond ) relative to ∼80% of its counterparts. We assess the impact of G...

Satellite galaxies undergo ram pressure stripping, where their gas is directly removed by a hydrodynamical interaction with the surrounding host halo gas. In clusters, ram-pressure-stripped tails of gas have been observe...

Deep, high-resolution spectroscopic observations have been obtained for six compact, strongly star-forming galaxies at redshift z ∼ 0.1–0.3, most of them also known as green peas. Remarkably, these galaxies show comp...

Context. The study of cluster substructures is important for the determination of the cluster dynamical status, assembly history, and the evolution of cluster galaxies, and it allows us to set constraints on the nature o...

We present an overview of the Middle Ages Galaxy Properties with Integral Field Spectroscopy (MAGPI) survey, a Large Program on the European Southern Observatory Very Large Telescope. MAGPI is designed to study the physi...

Aims. Bars are considered an efficient mechanism for transporting gas toward the central regions of galaxies and potentially enhance nuclear activity. However, the extent to which bars influence active galactic nuclei (A...

Among thousands of extragalactic γ -ray emitters, only a handful of distant ( z  > 3) sources are detected. Yet they are crucial probes, shedding light on the cosmic evolution of jets of active galactic nuclei and the...

We investigate five different models for the dark matter (DM) halo bias, that is, the ratio of the fluctuations of mass tracers to those of the underlying mass, by comparing their cosmological evolution using optical qua...

We use cosmological hydrodynamical simulations including star formation and metal enrichment to study the evolution of the chemical properties of galaxy-like objects at high redshift in the range 0.25 < z < 2.35 in a hie...

In this paper, the model of radial motion of dusty matter for the spherically symmetric case in General Relativity (GR) was developed. The model can be used, in particular, to describe galactic halos of dark matter. The ...
