Figure caption: Comparison of the reddening on the stellar continuum UV slope based on an SED fit, βSED (﹩{F}_{\lambda }\propto {\lambda }_{{\rm{rest}}}^{\beta }﹩; 1258 Å ≤ λrest ≤ 2580 Å; D. Calzetti et al. 1994), relative to the Balmer decrement, Hα/Hβ, for two galaxies at z = 1.9 in the Par 28 field. Left panels show an SED fit (black line) to COSMOS2020 photometry (red symbols; J. R. Weaver et al. 2022) using MAGPHYS (E. da Cunha et al. 2008; A. J. Battisti et al. 2020, mainly to demonstrate the wide rest-frame SED coverage for PASSAGE fields in COSMOS). The blue line is the prediction for the unattenuated stellar continuum. Right panels show the PASSAGE grism spectra. The upper galaxy has a lower Balmer decrement than the lower galaxy, indicating that the lower galaxy is experiencing more dust attenuation. This is reflected in the values of the UV slopes, with the upper left panel having a bluer UV slope than the lower left panel. By comparing SEDs for a large number of galaxies with Balmer decrements, we can derive the average dust attenuation curves and their evolution with galaxy properties.

Figure caption: Correlation of gas extinction (i.e., from Balmer decrement) with stellar mass. Error bars show the statistical uncertainties. Most PASSAGE dwarf galaxies have small or negligible extinction, but a significant minority are substantially dusty. On average, our new low-mass galaxies continue the trends found in somewhat more massive galaxies by the WISP survey and substantially more massive galaxies in MOSDEF (A. E. Shapley et al. 2022). Studies such as by A. J. Battisti et al. (2022), B. Lorenz et al. (2024), and A. Domínguez et al. (2013) highlight an offset in the dust attenuation–mass relationship depending on whether the fiber-region stellar mass or the total stellar mass is considered for Sloan Digital Sky Survey (SDSS) galaxies. For the SDSS galaxies, we have used the total stellar mass.

Figure caption: Massive galaxies follow the main sequence SFR–M⋆ relation (SFMS) at z ≈ 1, but low-mass galaxies scatter upward to very high Hα equivalent widths. Flux incompleteness at low masses (M⋆ ∼ 108 M⊙) flattens the slope of the relation. In addition to expanding the low-mass sample size by an order of magnitude, PASSAGE extends the mass regimes down to 107 M⊙ at z ∼ 2. The colored squares show detections from a single publicly released NIRISS/WFSS field of medium depth. Stellar masses were estimated from SED fitting, using PASSAGE and COSMOS photometry. SFRs were obtained from Hα luminosity, using the R. C. Kennicutt & N. J. Evans (2012) calibration. Error bars show the statistical uncertainties.

Figure caption: PASSAGE can distinguish between z > 8 Lyman break galaxies and low-redshift contaminants. A simulated z = 8.2 LBG is shown in the top row, detected by its Lyα break (rest-frame 1216 Å) in the deep observations. The slitless 2D spectra for the F115W, F150W, and F200W filters run from left to right. The spatial (vertical) scale is the same as in Figure 17. The last column shows the redshift probability distribution from template fitting. This simulation shows that PASSAGE correctly distinguishes between a z ∼ 8 LBG and a z = 2 dusty star-forming galaxy (middle row) or a z = 1.75 passive galaxy (bottom row), which are prime contaminants. We caution that if not all three wavelength regions are available, and no emission lines are detected, then the probability density functions (PDFs) for the high- and low-redshift solutions are not so unambiguously distinguished.

Figure caption: Total predicted multiple emission-line NIRISS galaxies for the 63 fields from PASSAGE, Cycle 1. All lines are detected at 5σ. The height of each box is the expected number of emitters and the width is the span of redshift. Each box is labeled with the set of multiple emission lines it represents. Not all possible line combinations are shown. There will also be many more multiple emission-line sources where only a single line will be detected at 5σ significance, but other lines will be robustly measurable at lower significance. The primary emission lines we use for redshift determinations, Hα/[S II] and/or [O III]/Hβ, are predicted to be available in almost 10,000 galaxies. This estimate is confirmed by our detailed inspection of the first PASSAGE fields.

Figure caption: PASSAGE measurements of the reddening-sensitive Balmer to Paschen emission-line ratio in a small sample of galaxies at z ≤ 0.7. These are plotted as a function of Hα line flux in cgs units. The dotted horizontal line shows the predicted intrinsic ratio of Hα/Paβ for Case B recombination with no extinction, AHα = 0. Some detections and upper limits are consistent with the Hα to Paβ ratio of 10, which is expected based on the typically assumed one magnitude of extinction at the wavelength of Hα (shown by the dashed line). However, several galaxies show significantly weaker Hα, indicative of greater reddening.

Figure caption: Gas-phase mass–metallicity relation of individual galaxies from one PASSAGE field compared to stacked results from the literature (M. Curti et al. 2017, 2023; A. Henry et al. 2021; R. L. Sanders et al. 2021; M. Li et al. 2023). A single PASSAGE field already extends the relation to objects of low stellar mass at 1.7 ≤ z ≤ 3.4.

Figure caption: Left panels: Spectrum of a star-forming dwarf galaxy at z = 0.086 from SDSS (black), overlaid with the HSC broad bands (upper left panel) and with the addition of the Merian medium bands (lower left panel). Photometry from the two Merian medium band filters, N708 and N540 (Y. Luo et al. 2024), when added to the photometry from the five HSC broad bands, grizy, provides a significant improvement in our ability to recover the redshift of dwarfs. The right panels show the redshift accuracy when using just the five-band HSC photometry (upper right panel) compared to the full seven-band photometry when the two Merian bands are added (lower right panel).

Figure caption: Dither pattern for the Merian Survey. In Merian-Wide (left), the survey footprint is covered with four-pass tilings with each tiling pattern offset from the previous one. The left panel shows a region of sky (6 × 6 deg2) covered with the Pass 1 tiling and a full four-pass coverage for a single pointing at the center, demonstrating the full depth. This pattern covers at least 98% of the pointings with four exposures. In Merian-Deep (right), the COSMOS field is observed with 41 dithered exposures offset from a fiducial pointing (red X mark) centered at ﹩\alpha =1{0}^{{\rm{h}}}0{0}^{{\rm{m}}}28\mathop{.}\limits^{{\rm{s}}}6﹩ by a radial angular separation of ﹩4.8{\rm{^{\prime} }}﹩, an evenly spaced azimuthal offset, and an additional random offset in both R.A. and decl. drawn from a uniform distribution.

Luo et al. 2024), alongside the HSC grizy broad-band filters (black) used in the HSC-SSP survey (H. Aihara et al. 2018). The shaded bands in the top panel indicate the redshift range in which rest-frame optical spectral lines of Hα, [O III], [O II], and Lyα fall within the two Merian filters.

Figure caption: The MBH–M⋆ (left) and MBH–Z (right) relations assumed in this paper. The seeding channels provide different evolutionary paths for IMBHs according to Population III stars (light seeds), runaway stellar mergers (moderate seeds), and direct collapse black holes (heavy seeds). The MBH–Z relation provides a convenient way to link the evolution of black hole masses with galaxy environment in photoionization simulations. The dark gray region indicates IMBHs largely ruled out by seeding mechanisms, while the light gray region indicates viable IMBH values.

The MZR adopted in this paper (black dashed line) results from merging the predictions of two different regimes similar to B. Indahl et al. (2021).
