We present a new model of the nebular emission from star-forming galaxies in a wide range of chemical compositions, appropriate to interpret observations of galaxies at all cosmic epochs. The model relies on the combination of state-of-the-art stellar population synthesis and photoionization codes to describe the ensemble of H ii regions and the diffuse gas ionized by young stars in a galaxy. A main feature of this model is the self-consistent yet versatile treatment of element abundances and… 
Synthetic nebular emission from massive galaxies – II. Ultraviolet-line diagnostics of dominant ionizing sources
We compute synthetic optical and ultraviolet (UV) emission-line properties of galaxies in a full cosmological framework by coupling, in post-processing, new-generation nebular-emission models with
Constraints on the production and escape of ionizing radiation from the emission-line spectra of metal-poor star-forming galaxies
We explore the production and escape of ionizing photons in young galaxies by investigating the ultraviolet and optical emission-line properties of models of ionization-bounded and density-bounded
Nebular-line emission during the Epoch of Reionization
Nebular emission lines associated with galactic H ii regions carry information about both physical properties of the ionized gas and the source of ionizing photons as well as providing the
Stellar and Nebular Diagnostics in the Ultraviolet for Star-forming Galaxies
There is a long history of using optical emission and absorption lines to constrain the metallicity and ionization parameters of gas in galaxies. However, comparable diagnostics are less
Star formation in the nearby dwarf galaxy DDO 53: interplay between gas accretion and stellar feedback
We present the results of a multiwavelength study of the nearby dwarf galaxy DDO 53 – a relatively isolated member of the M 81 group. We analyse the atomic and ionized gas kinematics (based on the
The MUSE Hubble Ultra Deep Field Survey
The physical origin of the near-ultraviolet Mg II emission remains an underexplored domain, unlike more typical emission lines that are detected in the spectra of star-forming galaxies. We explore
Physical properties and H-ionizing-photon production rates of extreme nearby star-forming regions
Measurements of the galaxy UV luminosity function at z 6 suggest that young stars hosted in low-mass star-forming galaxies produced the bulk of hydrogen-ionizing photons necessary to reionize the
Emission-line diagnostics of nearby H ii regions including interacting binary populations
We present numerical models of the nebular emission from H II regions around young stellar populations over a range of compositions and ages. The synthetic stellar pop- ulations include both single
Photoionization Models for the Semi-Forbidden C III] 1909 Emission in Star-Forming Galaxies
The increasing neutrality of the intergalactic medium at z>6 suppresses Ly-alpha emission, and spectroscopic confirmation of galaxy redshifts requires detecting alternative UV lines. The strong [C
Simulating and interpreting deep observations in the Hubble Ultra Deep Field with theJWST/NIRSpec low-resolution ‘prism’
The James Webb Space Telescope (JWST) will enable the detection of optical emission lines in galaxies spanning a broad range of luminosities out to redshifts z ≳ 10. Measurements of key galaxy
