	abstract = {We present new measurements of the evolution of the galaxy stellar mass 
functions (GSMFs) and ultraviolet luminosity functions (UV LFs) for
galaxies from z = 6-9 within the Frontier Field cluster MACSJ0416.1-2403
and its parallel field. To obtain these results, we derive the stellar
masses of our sample by fitting synthetic stellar population models to
their observed spectral energy distribution with the inclusion of
nebular emission lines. This is the deepest and farthest in distance
mass function measured to date and probes down to a level of
M* = 106.8 M⊙. The main result of
this study is that the low-mass end of our GSMF to these limits and
redshifts appears to become steeper from -1.98\_\{-0.07\}{\textasciicircum}\{+0.07\} at z = 6
to -2.38\_\{-0.88\}{\textasciicircum}\{+0.72\} at z = 9, steeper than previously observed mass
functions at slightly lower redshifts, and we find no evidence of
turnover in the mass range probed. We furthermore demonstrate that the
UV LF for these systems also appears to show a steepening at the highest
redshifts, without any evidence of turnover in the luminosity range
probed. Our MUV-M* relation exhibit shallower
slopes than previously observed and are in accordance with a constant
mass-to-light ratio. Integrating our GSMF, we find that the stellar mass
density increases by a factor of \{∼ \}15\_\{-6\}{\textasciicircum}\{+21\} from z = 9 to z =
6. We estimate the dust-corrected star formation rates (SFRs) to
calculate the specific SFRs (sSFR = SFR/M*) of our sample,
and find that for a fixed stellar mass of 5 × 109
M⊙, sSFR ∝ (1 + z)2.01 ± 0.16.
Finally, from our new measurements, we estimate the UV luminosity
density (ρUV) and find that our results support a smooth
decline of ρUV towards high redshifts.},
