“…There are about 60 known satellite galaxies of the MW [438], many of which have measurements of stellar kinematics from large ground-based telescopes and orbital properties (such as pericenter distances) constrained with Gaia data. Several surveys are now able to detect satellites in MW-like galaxies in the Local Volume and this number will grow in the coming years [439,437,440,441,56,442,443,444,445,446,447,448,449,450]. The implications of these measurements for general SIDM models remains to be fully explored.…”

“…The discovery and study of dwarf galaxies in the Local Group has prospered due to the great advances in wide field imaging surveys over the last two decades (e.g. Willman et al 2005a,b;Belokurov et al 2006Belokurov et al , 2007Belokurov et al , 2008Laevens et al 2015a,b;Koposov et al 2015a;Torrealba et al 2016Torrealba et al , 2018Torrealba et al , 2019Mau et al 2020;Cerny et al 2021aCerny et al ,b, 2022Sand et al 2022). The Sloan Digital Sky Survey (SDSS; York et al 2000;Abazajian et al 2009) led the early charge, with the Pan-STARRS consortium (Chambers et al 2016), the Dark Energy Survey (DES; Abbott et al 2018), and the DECam Local Volume Exploration Survey (DELVE; Drlica-Wagner et al 2021) contributing mightily to the discovery of Milky Way satellites, while the Pan-Andromeda Archaeological Survey (PAndAS; McConnachie et al 2009) has been prolific in finding dwarf galaxies around M31 (e.g.…”

“…All three show little to no gas content and predominantly old stellar populations formed roughly ∼ 9-10 Gyrs ago (Castellani et al 1996;Monelli et al 2010a,b;Savino et al 2019;Makarova et al 2017). Further away, at ∼ 2 Mpc, the only other examples of quiescent dwarfs known are KKR25 and KKs3 (Karachentsev et al 2015(Karachentsev et al , 2001, plus the recent discoveries of Tucana B (Sand et al 2022) and COSMOS-dw1 in the COSMOS-CANDELS field beyond the LG (Polzin et al 2021).…”
