Figure caption: J0405–3648: J0405–3648 is a low-mass (M ⋆ < 107 M ⊙) galaxy with a Gaussian H I profile characteristic of nonrotation or random gas motions of low-mass galaxies. Despite being fairly extended, with many small ionized clumps seen in the optical imaging, the H I profile width of J0405–3648 is narrow (FWHM ∼35 km s−1), suggesting few to no organized gas flows.

Figure caption: J1044+0353: J1044+0353 is a low-mass (M ⋆ < 107 M ⊙) galaxy with a Gaussian H I profile characteristic of nonrotation or random gas motions of low-mass galaxies. The profile width is a bit broader than other low-mass CLASSY galaxies (FWHM ∼65 km s−1), suggesting some organized gas flows, possibly related to a second star-forming clump (e.g., C. L. Martin et al. 2024).

Figure caption: J0942+3547: The HICLASS 21 cm observations of J0942+3547 have insufficient S/N to characterize the H I properties. The upper limit on S H I  corresponds to a very low gas fraction (μ < 0.09).

Figure caption: J1105+4444: J1105+445 is dominated by a UV-bright knot at its center, but has extended optical emission, possibly due to interacting clumps. The H I profile shows a very narrow Gaussian component atop a broader profile with a redshifted skew.

Figure caption: J1129+2034: Has a Gaussian H I profile characteristic of nonrotation or random gas motions of diskless galaxies. J1129+2034 also has a faint extended optical tail that could be the source of the slight asymmetry in its H I profile.

Figure caption: J0944+3442: J0944+3424 has extended disk-like optical emission. As a result, the H I profile appears like a broadened double-horn profile, which is typical of disk rotation.

Figure caption: J1314+3452: J1314+3452 is a relatively low-mass (M ⋆ < 107.5 M ⊙) galaxy with a Gaussian H I profile characteristic of nonrotation or random gas motions of low-mass galaxies. Despite having extended faint optical emission and one other UV-bright knot, the H I profile width is moderate (FWHM ∼60 km s−1), suggesting minimal organized gas flows.

Figure caption: J1418+2102: J1418+2102 is a low-mass (M ⋆ < 107 M ⊙) galaxy with an H I profile dominated by a narrow Gaussian (FWHM ∼50 km s−1) that is typical of nonrotation or random gas motions of low-mass galaxies. J1418+2102 has a second knot of star formation that may be responsible for redshifted emission in the 21 cm profile.

Figure caption: J1200+1343: J1200+1343 has a Gaussian H I profile characteristic of nonrotation or random gas motions. However, the profile has extended wings and is broad (FWHM ∼155 km s−1), suggesting some organized gas flows. This is the only H I profile in our sample that shows a significant deviation from the systemic velocity. This may be a result of its nearby companion.

Figure caption: J1225+6109: J1225+6109 is a low-mass galaxy (M ⋆ ∼ 107 M ⊙) with minimal extended optical emission. However, while the H I profile is fairly narrow (FWHM ∼60 km s−1), the profile looks double-horned and asymmetric, suggesting distorted organized gas flows.

Figure caption: J1157+3220: J1157+3220 is one of the more massive CLASSY galaxies (M ⋆ ∼ 109 M ⊙), with disk-like emission. As a result, the H I profile is approaching a double-horn shape, with a width of FWHM ∼190 km s−1.

Figure caption: J1132+1411: J1132+1411 is dominated by a compact UV-bright star-forming region, but appears to lie within a larger disk. The observed H I profile is fairly broad (FWHM ∼95 km s−1) and skewed to the blue, but the gas dynamics are not clear.

Figure caption: J0036–3333 (AGBT/14B-306): Also commonly known as the galaxy Haro 11, J0036–3333 contains multiple merging stellar populations, where the CLASSY coadded spectrum only focuses on the most UV luminous source, knot C (M. Hayes et al. 2007). The H I profile represents the integrated H I gas flows for J0036–3333 and shows a substantial blue wing. This is consistent with the recent report by A. Le Reste et al. (2024), who find that merger-driven interactions have caused a bulk offset of the neutral gas from the galaxy center and that the extended component is consistent with outflowing gas in the tidal tail. S. A. Pardy et al. (2016) found J0036-3333 to be gas-deficient compared with other nearby galaxies with similar optical properties, which A. Le Reste et al. (2024) determined was the result of a merger. Much of the gas that remained, post-merger, was photoionized by the interaction (V. Menacho et al. 2019), further driving μ toward a lower value (μ ∼ 0.3).

Figure caption: J0808+3948 (AGBT/06B-047): J0808+3948 tends to be a general outlier from the CLASSY sample. It lies at the upper end of the CLASSY mass–metallicity relationship, with a metallicity of 12+log(O/H) = 8.77 and a stellar mass of M ⋆ = 109.12 M ⊙, it appears to have a substantial older stellar population in its imaging and spectral energy distribution fitting, and has the most significant outflows among the CLASSY sample (﹩{v}_{{\rm{\min }}}\sim 600﹩ km s−1). For these reasons, J0808+3948 seems to have consumed most of its neutral gas reservoir, resulting in only an upper limit detection and a small gas fraction of μ ∼ 0.09.

Figure caption: J1444+4237: J1444+4237 is a low-mass (M ⋆ < 107 M ⊙) galaxy, but with an extended disk-like nature that seems to correspond to organized disk rotation in its double-horned H I profile.

Figure caption: J0934+5514 (C. M. Springob et al. 2005): This is the famous low-metallicity dwarf galaxy, I Zw 18. I Zw 18 has two main components, NW and SE, where the GBT observations encompass both. The main body of the H I profile appears Gaussian, characteristic of the random gas motions of diskless low-mass galaxies. However, a weaker blue tail is present that may be associated with gas flows between the NW and SE components.

Figure caption: J0944–0038 (M. J. Meyer et al. 2004): Commonly known as the metal-poor galaxy CGCG 007-025, J0944–0038 contains multiple star-forming knots that may be interacting, causing kinematic disturbances to the H I gas. As a result, the H I profile appears asymmetric and double-peaked, with a broad width (FWHM ∼120 km s−1).

Figure caption: J0926+4427 (AGBT/11A-057): Despite it having a high SFR and a large upper limit on the H I gas mass and gas fraction, 21 cm emission is not significantly detected in the archival GBT data for J0926+4427. This may simply be due to its higher redshift (z = 0.18) and the rather strong RFI that is present in its continuum.

Figure caption: J0823+2806 (AGBT/11A-057): The CLASSY coadded spectrum of J0823+2806 is focused on UV-bright emission from a single massive star cluster; however, the total galaxy shows extended tails to both the N and S. This structure, likely due to interactions, produces the broad H I profile that is observed.

Figure caption: J1024+0524 (AGBT/19A-301): The archival 21 cm observations of J1024+0524 have insufficient S/N to characterize the H I properties. With a total exposure time of about 3 minutes on target, we are not confident that this galaxy would still be nondetected if it was observed for longer.

Figure caption: The Doppler broadening from a simultaneous fit to solely the Fe II lines (y-axis) compared to that for the other LIS lines (x-axis). The solid orange points correspond to the galaxies that are well-fit by a single component, while the empty points require at least two components. The dashed line corresponds to a one-to-one relationship, while the solid line is the linear best-fit to the solid orange points. We found that the Doppler broadening of the Fe II lines were nearly always smaller than those for the other lines. This indicates a non-negligible thermal component to b.

Figure caption: Comparing the equivalent widths measured from the observed data with those measured from the models. C II and Si II lines, as measured from our fits, are with 10% of those measured from the data even when the multi-component galaxies are included. The lines associated with O I and Al II generally have percent errors <20%, while those for S II lines are generally <35%. This indicates that the measurements of W  λ  from our fits are largely in agreement with those measured directly from the data.

Figure caption: J1119+5130 (AGBT/05A-034): J1119+5130 is a low-mass (M ⋆ < 107 M ⊙) galaxy with a Gaussian H I profile characteristic of nonrotation or random gas motions of low-mass galaxies. The profile width is a bit broader than other low-mass CLASSY galaxies (FWHM ∼100 km s−1), suggesting some organized gas flows possibly related to its extended optical emission.
