Ly$\alpha$ Escape in JWST/NIRCam F430M-Selected H$\alpha$ Emitters at $z\simeq 5.5$

Cheng Cheng, Zhen-Ya Zheng, Chunyan Jiang +8

We study the Ly$\alpha$ escape fraction ($f_{\mathrm{esc}}$) in an H$\alpha$-selected sample of star-forming galaxies at $z\simeq 5.5$, identified via JWST/NIRCam F430M excess and covered by archi…
