  • The JWST Extragalactic Medium-band Survey (JEMS) is a deep Cycle 1 imaging survey program using 5 medium-band filters at 2 and 4 microns (F182M, F210M, F430M, F460M, F480M). With two NIRCam detector footprints (using all 5 filters) and one NIRISS imaging footprint (using F430M and F480M filters), the data total 15.6 square arcminutes with integration times 13915-27830 seconds, including full coverage of the Hubble Ultra Deep Field (HUDF), building on the deepest multi-wavelength public datasets available anywhere on the sky. These science-ready mosaics reach 5s point source limits (ABmag) of 29.2 in 2µm filters and 28.2-28.6 at 4µm. The chosen filters create a JWST imaging survey in the UDF that enables novel analysis of a range of spectral features potentially across the redshift range of 0.3 < z < 20, including Paschen-a, Ha+[N II], and [O III]+Hbeta emission at high spatial resolution.

  • GUVPNcat is a catalog matching all confirmed and possible PNe (PNcat) with the Galaxy Evolution Explorer (GALEX) UV sky surveys, the Sloan Digital Sky Survey (SDSS) data release 16 (DR16), and the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) PS1 second release. A total of 671 PNe were observed by GALEX in far-UV and/or near-UV, 83 PNe by SDSS, and 1819 by Pan-STARRS. These matched catalogs were merged into one table containing a total of 375 PNe, with UV and optical photometry over a total spectral coverage of about 1540-9610Å. View GUVPNcat Collection Page >
