Figure caption: Spatial distribution of candidate gravitational lenses in the DES/DECaLS fields (gray circles) and the 77 spectroscopic redshifts from our AGEL survey (pink stars; Table 3) where the secured redshift is of the deflector (foreground) and/or the source (background). The confirmed gravitational lenses span a range in R.A., and most are at declinations near the equator and can be observed by telescopes in both hemispheres; the plane of the Milky Way is shown as the green curve. Several of the confirmed strong lenses are targeted in the HST SNAP program #15867 (open black circles) that provides the high-angular-resolution imaging needed to model the gravitational lenses; additional HST imaging of AGEL systems is ongoing in Cycle 29 (#16773).

Figure caption: Example of spectroscopic redshifts with redshift quality flag Q  z  < 3. From top to bottom: probable Hα emission for source with Q  z  = 1 (single line); probable C IV absorption with Q  z  = 2.5 (also weak C III]); probable calcium absorption with Q  z  = 1 (lines not centered); probable calcium absorption with Q  z  = 2. In our analysis, we use spectroscopic redshifts with Q  z  ≥ 2.

Figure caption: We compare spectroscopic redshifts for the deflectors to photometric redshifts for 23 systems and find that z phot and z spec are remarkably consistent. The average photometric and spectroscopic redshifts are ﹩\left\langle {z}_{\mathrm{phot}}\right\rangle =0.63\pm 0.10﹩ and ﹩\left\langle {z}_{\mathrm{spec}}\right\rangle =0.62\pm 0.11﹩, and the average absolute difference is ﹩\left\langle | \delta z| /(1+{z}_{\mathrm{spec}})\right\rangle =0.03\pm 0.02﹩. The photometric redshifts were determined using BPZ and have rms errors of Δz ∼ 0.06(1 + z spec) (Benítez 2000).

Figure caption: Most of the AGEL systems targeted for spectroscopic follow-up are brighter than r = 21 mag (foreground deflector; see Figure 1). The total r-band magnitudes (AB system) are from the DESI Legacy Survey Data Release 9 and determined using TRACTOR to model the photometry (Dey et al. 2019). For AGEL, we focus mainly on candidate lenses from the DES and DECaLS fields but also include candidates lenses from existing surveys such as CASSOWARY (Stark et al. 2013).
Paper: Discovery of 34 Low-mass Comoving Systems Using NOIRLab Source Catalog DR2

Figure caption: Top left panel: optical spectrum of NSC J015340.10-001550.34 A (primary of system #8) compared to three M dwarf standards from Bochanski et al. (2007). The spectrum of our primary (smoothed for a better comparison) fits best with the M1 standard. Bottom left panel: unsmoothed version of the same spectrum with the M1 standard overplotted. Top right panel: near-infrared spectrum of NSC J045724.25-230012.74 B (secondary of system #21) compared to three T dwarf standards from Burgasser et al. (2004). The spectrum of our secondary (smoothed for a better comparison) fits best with the T3 standard. Bottom right panel: unsmoothed version of the same spectrum with the T3 standard overplotted.

Figure caption:  Mass ratio (secondary/primary) vs. projected separation for literature sources (various color-coded filled circles) taken from Faherty et al. (2020) and Faherty et al. (2021; various color-coded filled circles) and companions from this paper (black five-pointed stars). We have color-coded the exoplanet detections (as defined by the Exoplanet Archive) by the detection method of the source.
