The predicted luminous satellite populations around SMC and LMC-mass galaxies - A missing satellite problem around the LMC?

Abstract

Recent discovery of many dwarf satellite galaxies in the direction of the Small and Large Magellanic Clouds (SMC and LMC) provokes questions of their origins, and what they can reveal about galaxy evolution theory. Here, we predict the satellite stellar mass function of Magellanic Cloud-mass host galaxies using abundance matching and reionization models applied to the \textit{Caterpillar} simulations. Specifically focusing on the volume within $50$~kpc of the LMC, we predict a mean of 4-8 satellites with stellar mass $M_{\ast }>10^4{\mathrm{M}}_{\odot }$, and 3-4 satellites with $80<M_{\ast }\le 3000{\mathrm{M}}_{\odot }$. Surprisingly, all $12$ currently known satellite candidates have stellar masses of $80<M_{\ast }\le 3000{\mathrm{M}}_{\odot }$. Reconciling the dearth of large satellites and profusion of small satellites is challenging and may require a combination of a major modification of the \mstarmhalo relationship (steep, but with an abrupt flattening at $10^3{\mathrm{M}}_{\odot }$), late reionization for the Local Group ($z_{\mathrm{reion}}\lesssim 9$ preferred), and/or strong tidal stripping. We can more robustly predict that $\sim 53\%$ of satellites within this volume were accreted together with the LMC and SMC, and $\sim 47\%$ were only ever Milky Way satellites. Observing satellites of isolated LMC-sized field galaxies is essential to placing the LMC in context, and to better constrain the \mstarmhalo relationship. Modeling known LMC-sized galaxies within $8$ Mpc, we predict 1-6 (2-12) satellites with $M_{\ast }>10^5{\mathrm{M}}_{\odot }$ ($M_{\ast }>10^4{\mathrm{M}}_{\odot }$) within the virial volume of each, and 1-3 (1-7) within a single $1.5^{\circ }$ diameter field of view, making their discovery likely.
