We present hydrodynamical star-forming simulations in the Milgromian dynamics(MOND) framework of a gas-rich disc galaxy with properties similar to AGC114905, which has recently been argued to have a rotation curve (RC) that isinconsistent with the MOND prediction. Our first model considers the galaxy inisolation, while our second model includes an external field of $0.05 \,a_{_0}$, the estimated gravitational field from large-scale structure. We showthat isophotes in the face-on view can differ from circular at the 50% level.This could mislead observers into overestimating the inclination $i$ betweendisc and sky planes. Because RCs require a correction factor of $1/\sin i$, theactual RC could be much higher than reported by observers. This plausiblyreconciles AGC 114905 with MOND expectations.

Overestimated inclinations of Milgromian disc galaxies: the case of the ultradiffuse galaxy AGC 114905
