A High-Resolution Hubble Space Telescope Study of Apparent Lyman Continuum Leakers at $z\sim3$

Understand

We present $U_{336}V_{606}J_{125}H_{160}$ follow-up $HST$ observations of 16 $z\sim3$ candidate LyC emitters in the HS1549+1919 field.

• With these data, we obtain high spatial-resolution photometric redshifts of all sub-arcsecond components of the LyC candidates in order to eliminate foreground contamination and identify robust candidates for leaking LyC emission.
• Of the 16 candidates, we find one object with a robust LyC detection that is not due to foreground contamination.
• This object (MD5) resolves into two components; we refer to the LyC-emitting component as MD5b.
