Missing satellites? No problem!

Koposov et al.,

The authors perform a comprehensive analysis of the "missing satellite problem", taking into account realistic selection effects from the SDSS. As the figure above shows, with relatively simple prescriptions for star formation in these halos (e.g. suppression of gas accretion after reionization in halos with v<35 km/s), the data (black bars) actually agree with the fiducial  model (green band).
