Paper abstract bibtex The MAMMOTH-Grism slitless spectroscopic survey is a Hubble Space Telescope (HST) cycle-28 medium program, which is obtaining 45 orbits of WFC3/IR grism spectroscopy in the density peak regions of three massive galaxy protoclusters at \$z=2-3\$ discovered using the MAMMOTH technique. We introduce this survey by presenting the first measurement of mass-metallicity relation (MZR) at high redshift in overdense environments via grism spectroscopy. From the completed MAMMOTH-Grism observation in the field of the BOSS1244 protocluster at \$z=2.24{\textbackslash}pm0.02\$, We secure a sample of 36 protocluster member galaxies at \$z{\textbackslash}sim2.24\$, showing strong nebular emission lines ([O III], H\${\textbackslash}beta\$ and [O II]) in their G141 spectra. Using the multi-wavelength broad-band deep imaging from HST and ground-based telescopes, we measure their stellar masses in the range of \$[10{\textasciicircum}\{9\},10{\textasciicircum}\{10.4\}]M_{\textbackslash}odot\$, instantaneous star formation rates (SFR) from 10 to 240\$M_{\textbackslash}odot yr{\textasciicircum}\{-1\}\$, and global gas-phase metallicities [1/3,1] of solar. Compared with similarly selected field galaxy sample at the same redshift, our galaxies show on average increased SFRs by \textasciitilde0.06dex and \textasciitilde0.18dex at \textasciitilde10\${\textasciicircum}\{10.1\}M_{\textbackslash}odot\$ and \textasciitilde10\${\textasciicircum}\{9.8\}M_{\textbackslash}odot\$, respectively. Using the stacked spectra of our sample galaxies, we derive the MZR in the BOSS1244 protocluster core as \$12+{\textbackslash}log(\{{\textbackslash}rm O/H\})=(0.136{\textbackslash}pm0.018){\textbackslash}times{\textbackslash}log(M_{\textbackslash}ast/M_{\textbackslash}odot)+(7.082{\textbackslash}pm0.175)\$, showing significantly shallower slope than that in the field. This shallow MZR slope is likely caused by the combined effects of efficient recycling of feedback-driven winds and cold-mode gas accretion in protocluster environments. The former effect helps low-mass galaxies residing in overdensities retain their metal production, whereas the latter effect dilutes the metal content of high-mass galaxies, making them more metal poor than their coeval field counterparts.
