Nebular dominated galaxies: insights into the stellar initial mass function at high redshift

Alex J. Cameron, Harley Katz, Callum Witten +3

We identify a low-metallicity ($12+\log (\mathrm{O}/\mathrm{H})=7.59$) Ly$\alpha$-emitting galaxy at $z=5.943$ with evidence of a strong Balmer jump, arising from nebular continuum. While Balm…
