Footprints in the Wind: Probing X-ray Outflows in NGC 7469 using Near-Infrared Emission Lines Open
AGN winds play an important role in the co-evolution of supermassive black holes and their host galaxies, yet their driving mechanisms and impact on star formation remain subjects of active investigation. Critically, the lack of X-ray Inte…

Updates to the WFC3/UVIS Saturation Map Open
The calwf3 software for WFC3/UVIS utilizes a reference file to flag pixels that are saturated beyond their full-well depth. Previously, this was accomplished using a constant threshold of 65,500 e$^{-}$ across the entire detector. In this …

The Shape of AGN-driven Winds in the Seyfert Galaxy NGC 3516 Open
Active galactic nuclei (AGN) are known to drive ionized gas into their host galaxies, which may affect the evolution of both the central supermassive black holes and their hosts. In the case of NGC 3516, a nearby Seyfert 1 galaxy, these AG…
