Physical properties and H-ionizing-photon production rates of extreme nearby star-forming regions
Jacopo Chevallard, Stéphane Charlot, Peter Senchyna +7
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…
Ultraviolet spectra of extreme nearby star-forming regions --- approaching a local reference sample for JWST
Peter Senchyna, Daniel P. Stark, Alba Vidal-García +7
Nearby dwarf galaxies provide a unique laboratory in which to test stellar population models below . Such tests are particularly important for interpreting the surprisin…
Modelling the nebular emission from primeval to present-day star-forming galaxies
Julia Gutkin, Stephane Charlot, Gustavo Bruzual
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…
Lyman-alpha and CIII] Emission in z=7-9 Galaxies: Accelerated Reionization Around Luminous Star Forming Systems?
Daniel P. Stark, Richard S. Ellis, Stephane Charlot +9
We discuss new Keck/MOSFIRE spectroscopic observations of four luminous galaxies at z~7-9 selected to have intense optical line emission by Roberts-Borsani et al. (2016). Previous…
Nuclear activity versus star formation: emission-line diagnostics at ultraviolet and optical wavelengths
Anna Feltre, Stephane Charlot, Julia Gutkin
In the context of observations of the rest-frame ultraviolet and optical emission from distant galaxies, we explore the emission-line properties of photoionization models of active…
Spectroscopic detection of CIV in a galaxy at z=7.045: Implications for the ionizing spectra of reionization-era galaxies
Daniel P. Stark, Gregory Walth, Stephane Charlot +9
We present Keck/MOSFIRE observations of UV metal lines in four bright gravitationally-lensed z~6-8 galaxies behind the cluster Abell 1703. The spectrum of A1703-zd6, a highly-magni…
Spectroscopic detections of CIII]1909 at z~6-7: A new probe of early star forming galaxies and cosmic reionisation
Daniel P. Stark, Johan Richard, Stephane Charlot +7
Deep spectroscopic observations of z~6.5 galaxies have revealed a marked decline with increasing redshift in the detectability of Lyman-alpha emission. While this may offer valuabl…
Ultraviolet Emission Lines in Young Low Mass Galaxies at z~2: Physical Properties and Implications for Studies at z>7
Daniel P. Stark, Johan Richard, Brian Siana +8
We present deep spectroscopy of 17 very low mass (M* ~ 2.0x10^6 Msun to 1.4x10^9 Msun) and low luminosity (M_UV ~ -13.7 to -19.9) gravitationally lensed galaxies in the redshift ra…
Feedback regulated star formation: II. dual constraints on the SFE and the age spread of stars in massive clusters
Sami Dib, Julia Gutkin, Wolfgang Brandner +1
We show that the termination of the star formation process by winds from massive stars in protocluster forming clumps imposes dual constraints on the star formation efficiencies (S…
