“…The 3D algorithm GalPaK 3D allows to fit the kinematics and morphological parameters simultaneously and thus no prior information is required on the inclination 3 . The agreement between HST-based and MUSE-based inclinations is typically better than 7 • (rms) for galaxies with 25 < i < 80 as demonstrated in Contini et al (2016) and with mock data-cubes (Bouché et al 2021) derived from the Illustris "NewGeneration 50 Mpc" (TNG50) simulations (Nelson et al 2019;Pillepich et al 2019). Nonetheless, we checked that the inclinations i and Sérsic n parameters obtained from the [O ii] MUSE data are consistent with those obtained from the HST/F160W images (see Tables 1 and 2).…”

“…The sample of [O ii] emitters was selected from the mosaic catalogue (Inami et al 2017) where we chose galaxies with the highest S/N per spaxel in [O ii] that were not face-on (using the [O ii] inclinations estimated in Bouché et al 2021). From the catalog, we found 9 galaxies matching these criteria, listed in Table 1, with some reaching S /N pix ∼ 100 in the central spaxel.…”

“…For the kinematics, the 3D model uses a parametric form for the rotation curve v(r) and the dispersion σ(r) profile as discussed in Bouché et al (2021). In order to assess the shape of the RCs, we can use several RC models which allow for a rising or declining RC, such as in Rix et al (1997), Courteau (1997) or the universal RC (URC) of Persic et al (1996, PSS96).…”

“…Finally, as described in Bouché et al (2015aBouché et al ( , 2021, the velocity dispersion profile σ t (r) consists of the combination of a thick disk σ thick , defined from the identity σ thick (r)/v(r) = h z /r (Genzel et al 2006;Cresci et al 2009) where h z is the disk thickness (taken to be 0.15 × R e ) and a dispersion floor, σ 0 , added in quadrature (similar to σ 0 in Genzel et al 2006Genzel et al , 2008Förster Schreiber et al 2006Cresci et al 2009;Wisnioski et al 2015;Übler et al 2019).…”

“…Recently, 3D algorithms such as GalPaK 3D (Bouché et al 2015a) or 3D Barolo (Di Teodoro & Fraternali 2015) have pushed the limits of what can be achieved at high-redshifts. For instance, one can study the kinematics of low mass SFGs, down to 10 8 M (as in Bouché et al 2021) in the regime of low S/Ns or study the kinematics of SFGs at large galactic radii ∼3 × R e as in Sharma et al (2021), when combined with stacking techniques. Most relevant for this paper, disk-halo decompositions of distant galaxies have been performed with 3D Barolo at z 4 on bright submm [CII] ALMA sources (Rizzo et al 2020;Neeleman et al 2020;Fraternali et al 2021).…”

Context. Disc-halo decompositions z = 1 − 2 star-forming galaxies (SFGs) at z > 1 are often limited to massive galaxies (M⋆ > 1010 M⊙) and rely on either deep integral field spectroscopy data or stacking analyses. Aims. We present a study of the dark-matter (DM) content of nine z ≈ 1 SFGs selected among the brightest [O II] emitters in the deepest Multi-Unit Spectrograph Explorer (MUSE) field to date, namely the 140 h MUSE Extremely Deep Field. These SFGs have low stellar masses, ranging from 108.5 to 1010.5 M⊙. Methods. We analyzed the kinematics with a 3D modeling approach, which allowed us to measure individual rotation curves to ≈3 times the half-light radius Re. We performed disk-halo decompositions on their [O II] emission line with a 3D parametric model. The disk-halo decomposition includes a stellar, DM, gas, and occasionally a bulge component. The DM component primarily uses the generalized α, β, γ profile or a Navarro-Frenk-White profile. Results. The disk stellar masses M⋆ obtained from the [O II] disk-halo decomposition agree with the values inferred from the spectral energy distributions. While the rotation curves show diverse shapes, ranging from rising to declining at large radii, the DM fractions within the half-light radius fDM(< Re) are found to be 60% to 95%, extending to lower masses (densities) recent results who found low DM fractions in SFGs with M⋆ > 1010 M⊙. The DM halos show constant surface densities of ∼100 M⊙ pc−2. For isolated galaxies, half of the sample shows a strong preference for cored over cuspy DM profiles. The presence of DM cores appears to be related to galaxies with low stellar-to-halo mass ratio, log M⋆/Mvir ≈ −2.5. In addition, the cuspiness of the DM profiles is found to be a strong function of the recent star-formation activity. Conclusions. We measured the properties of DM halos on scales from 1 to 15 kpc, put constraints on the z > 0 cvir − Mvir scaling relation, and unveiled the cored nature of DM halos in some z ≃ 1 SFGs. These results support feedback-induced core formation in the cold dark matter context.

We present the second data release of the MUSE Hubble Ultra-Deep Field surveys, which includes the deepest spectroscopic survey ever performed. The MUSE data, with their 3D content, amazing depth, wide spectral range, and excellent spatial and medium spectral resolution, are rich in information. Their location in the Hubble ultra-deep field area, which benefits from an exquisite collection of ancillary panchromatic information, is a major asset. This update of the first release incorporates a new 141-hour adaptive-optics-assisted MUSE eXtremely Deep Field (MXDF; 1 arcmin diameter field of view) in addition to the reprocessed 10-hour mosaic (3 × 3 arcmin 2 ) and the single 31-hour deep field (1 × 1 arcmin 2 ). All three data sets were processed and analyzed homogeneously using advanced data reduction and analysis methods. The 3σ point-source flux limit of an unresolved emission line reaches 3.1×10 −19 and 6.3×10 −20 erg s −1 cm −2 at 10-and 141-hour depths, respectively. We have securely identified and measured the redshift of 2221 sources, an increase of 41% compared to the first release. With the exception of eight stars, the collected sample consists of 25 nearby galaxies (z < 0.25), 677 [O ii] emitters (z = 0.25 − 1.5), 201 galaxies in the MUSE redshift desert range (z = 1.5 − 2.8), and 1308 Lyα emitters (z = 2.8 − 6.7). This represents an order of magnitude more redshifts than the collection of all spectroscopic redshifts obtained before MUSE in the Hubble ultra-deep field area (i.e., 2221 versus 292). At high redshift (z > 3), the difference is even more striking, with a factor of 65 increase (1308 versus 20). We compared the measured redshifts against three published photometric redshift catalogs and find the photo-z accuracy to be lower than the constraints provided by photo-z fitting codes. Eighty percent of the galaxies in our final catalog have an HST counterpart. These galaxies are on average faint, with a median AB F775W magnitude of 25.7 and 28.7 for the [O ii] and Lyα emitters, respectively. Fits of their spectral energy distribution show that these galaxies tend to be low-mass star-forming galaxies, with a median stellar mass of 6.2 × 10 8 M and a median star-formation rate of 0.4 M yr −1 . We measured the completeness of our catalog with respect to HST and found that, in the deepest 141-hour area, 50% completeness is achieved for an AB magnitude of 27.6 and 28.7 (F775W) at z = 0.8 − 1.6 and z = 3.2 − 4.5, respectively. Twenty percent of our catalog, or 424 galaxies, have no HST counterpart. The vast majority of these new sources are high equivalent-width z > 2.8 Lyα emitters that are detected by MUSE thanks to their bright and asymmetric broad Lyα line. We release advanced data products, specific software, and a web interface to select and download data sets.
