Star-forming galaxies in galaxy clusters play a crucial role in understanding the advanced stages of galaxy evolution within dense environments. We present a sample of 3.3 μ m polycyclic aromatic hydrocarbon (PAH)-bright galaxies in the A2744 galaxy cluster. Using F430M medium-band images, we select...
