20.500.12556/RUL-176537 Parallel application of slitless spectroscopy to analyze galaxy evolution (PASSAGE): survey overview During the second half of Cycle 1 of the James Webb Space Telescope (JWST), we conducted the Parallel Application of Slitless Spectroscopy to Analyze Galaxy Evolution (PASSAGE) program. PASSAGE received the largest allocation of JWST observing time in Cycle 1, 591 hr of NIRISS observations to obtain direct near-IR imaging and slitless spectroscopy. About two-thirds of this was ultimately executed, to observe 63 high-latitude fields in pure-parallel mode. These have provided more than 10,000 near-infrared grism spectrograms of faint galaxies. PASSAGE brings unique advantages in studying galaxy evolution: (a) Unbiased spectroscopic search, without prior photometric preselection. By including the typical galaxies which have low masses and strong emission lines, slitless spectroscopy is the indispensable complement to any pretargeted spectroscopy. (b) The combination of several dozen independent fields to overcome cosmic variance. (c) Near-infrared spectral coverage, spanning a wide wavelength range of up to 1.0 to 2.3 μm, with minimal wavelength gaps, to measure multiple diagnostic rest-frame optical lines, minimizing sensitivity to dust reddening. (d) JWST’s unprecedented spatial resolution, in some cases using two orthogonal grism orientations, to overcome contamination due to blending of overlapping spectra. (e) Discovery of rare bright objects especially for detailed JWST follow-up. PASSAGE data are public immediately, and our team plans to deliver fully processed high-level data products. In this PASSAGE overview, we describe the survey and data quality, and present examples of these accomplishments in several areas of current interest in the evolution of emission-line galaxy properties, particularly at low masses. astrophysics galaxies galaxy evolution early universe astrofizika galaksije razvoj galaksij zgodnje vesolje true false true Angleški jezik Slovenski jezik Članek v reviji 2025-12-03 10:33:08 2025-12-03 10:33:09 2025-12-22 03:59:14 0000-00-00 00:00:00 2025 0 0 17 str. no. 1, art. no. 152 Vol. 993 Nov. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 524.8 1538-4357 10.3847/1538-4357/ae00bb 259732739 Malkan_2025_ApJ_993_152.pdf Malkan_2025_ApJ_993_152.pdf 1 F148F970A8F9F3D2F7DF4779294D7EB2 f2e0307dab9510ce20f3c2aa035eed12e418ec0bc56964d01d60f9d32fe9a029 1b278c8c-d02e-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=222921 https://iopscience.iop.org/article/10.3847/1538-4357/ae00bb 0 253536e8-d02e-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=222922 Fakulteta za matematiko in fiziko 0 0 0
