Applications of alternative gravity to the recent 2021 Bizyaev et al. Ultra-faint edge-on galaxies

In recent years, elements of standard gravity have come into question due to the lack of observational evidence of dark matter. Further, new empirical patterns present in rotation curve data have given new testable features for standard and alternative gravity. In this presentation we examine a very recent survey conducted by Bizyaev et al. (2021), which consists of 138 superthin edge-on galaxies to which rotation curves were observed. From this set, we examine the 20 rotation curves considered to be of the highest quality, which encompasses a variety of red and blue galaxies. In this work, we expand upon the modeling done by Bizyaev et al., and further apply alternative gravity to rotation curve models. For the scope of this work we include Conformal Gravity, Modified Newtonian Dynamics (MOND), and the Radial Acceleration Rule (RAR). For each of the alternative gravitational theories, rotation curve fits, as well as the baryonic Tully-Fisher relation and the RAR are explored, thus giving us a robust first treatment of this modern galactic data set through the lens of alternative gravity.
