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}}}...

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...

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...

Context. Recent efforts to identify secondary variations in the halo occupation distribution (HOD) have primarily focused on simulations that examine the role of large-scale cosmic environments, such as superclusters, fi...
