Lyman-alpha spectroscopy of extreme [OIII] emitting galaxies at : Implications for Ly visibility and LyC leakage at
Mengtao Tang, Daniel Stark, Jacopo Chevallard +3
Spectroscopic observations of massive galaxies selected to have extremely large [OIII]+H equivalent width (EW Å) have recently revealed large Ly detection ra…
Metal-THINGS: On the metallicity and ionization of ULX sources in NGC 925
Maritza A. Lara-López, Igor A. Zinchenko, Leonid S. Pilyugin +13
We present an analysis of the optical properties of three Ultra Luminous X-ray (ULX) sources identified in NGC 925. We use Integral field unit data from the George Mitchel spectrog…
How robustly can we constrain the low-mass end of the stellar mass function? -- The limits of lensing models and stellar population assumptions in the Hubble Frontier Fields
Lukas J. Furtak, Hakim Atek, Matthew D. Lehnert +2
We present new measurements of the very low-mass end of the galaxy stellar mass function (GSMF) at computed from a rest-frame ultraviolet selected sample of dropout gala…
Investigating Clumpy Galaxies in the Sloan Digital Sky Survey Stripe 82 using the Galaxy Zoo
Vihang Mehta, Claudia Scarlata, Lucy Fortson +7
Giant, star-forming clumps are a common feature prevalent amongst high-redshift star-forming galaxies and play a critical role in shaping their chaotic morphologies and yet, their…
Stars and gas in the most metal-poor galaxies I: COS and MUSE observations of SBS 0335-052E
A. Wofford, A. Vidal-García, A. Feltre +5
Among the nearest most metal-poor starburst-dwarf galaxies known, SBS 0335-052E is the most luminous in integrated nebular He II λ4686 emission. This makes it a unique target to te…
MMT Spectroscopy of Lyman-alpha at z7: Evidence for Accelerated Reionization Around Massive Galaxies
Ryan Endsley, Daniel P. Stark, Jacopo Chevallard +4
Reionization-era galaxies tend to exhibit weak Ly emission, likely reflecting attenuation from an increasingly neutral IGM. Recent observations have begun to reveal exceptions t…
Ultraviolet spectra of extreme nearby star-forming regions: evidence for an overabundance of very massive stars
Peter Senchyna, Daniel P. Stark, Stéphane Charlot +3
As deep spectroscopic campaigns extend to higher redshifts and lower stellar masses, the interpretation of galaxy spectra depends increasingly upon models for very young stellar po…
Rest-frame UV spectroscopy of extreme [OIII] emitters at : Toward a high-redshift UV reference sample for JWST
Mengtao Tang, Daniel Stark, Jacopo Chevallard +3
Deep spectroscopy of galaxies in the reionization-era has revealed intense CIII] and CIV line emission (EW Å). In order to interpret the nebular emission emerging at …
The [OIII]H Equivalent Width Distribution at z7: Implications for the Contribution of Galaxies to Reionization
Ryan Endsley, Daniel P. Stark, Jacopo Chevallard +1
We quantify the distribution of [OIII]+H line strengths at z7 using a sample of 20 bright (M 21) galaxies. We select these systems over wid…
Simulating JWST deep extragalactic imaging surveys and physical parameter recovery
O. B. Kauffmann, O. Le Fèvre, O. Ilbert +7
We present a new prospective analysis of deep multi-band imaging with the James Webb Space Telescope (JWST). In this work, we investigate the recovery of high-redshift gal…
Modelling the M*-SFR relation at high redshift: untangling factors driving biases in the intrinsic scatter measurement
E. Curtis-Lake, J. Chevallard, S. Charlot +1
We present a method to self-consistently propagate M and SFR () uncertainties onto intercept, slope and intrinsic scatter estimates for a simple model of the main sequence…
