The Luminosity Function of the Milky Way Satellites
We quantify the algorithmic detectability of stellar Milky Way satellites in data release 5 (DR5) of the Sloan Digital Sky Survey (SDSS), and use this to estimate the luminosity function of faint satellite galaxies in our halo. We develop a satellite detection algorithm based on the convolution of the DR5 star catalog with a kernel of zero net flux that is the difference of a narrow positive Ga...
متن کاملHundreds of Milky Way satellites? Luminosity bias in the satellite luminosity function
We correct the observed Milky Way satellite luminosity function for luminosity bias using published completeness limits for the Sloan Digital Sky Survey DR5. Assuming that the spatial distribution of Milky Way satellites tracks the subhalos found in the Via Lactea ΛCDM N-body simulation, we show that there should be between ∼ 300 and ∼ 600 satellites within 400 kpc of the Sun that are brighter ...
متن کاملluminosity function of faint point sources in the Milky Way
We assess contribution to the X-ray (above 2 keV) luminosity of the Milky Way from different classes of low-mass binary systems and single stars. We begin by using the RXTE Slew Survey of the sky at |b| > 10 to construct an X-ray luminosity function (XLF) of nearby X-ray sources in the range 10 erg s < Lx < 10 34 erg s (where Lx is the luminosity over 2–10 keV), occupied by coronally active bin...
متن کاملLuminous Satellites Ii: Spatial Distribution, Luminosity Function and Cosmic Evolution
We infer the normalization and the radial and angular distributions of the number density of satellites of massive galaxies (log10[M*h/M �] > 10.5) between redshifts 0.1 and 0.8 as a function of host stellar mass, redshift, morphology, and satellite luminosity. Exploiting the depth and resolution of the COSMOS Hubble Space Telescope images, we detect satellites up to 8 mag fainter than the host...
متن کاملThe Universe behind the Southern Milky Way
A first analysis of a deep blind HI survey covering the southern Zone of Avoidance plus an extension towards the north (196 ≤ l ≤ 52) obtained with the Multibeam receiver at the 64m Parkes telescope reveals slightly over a thousand galaxies within the latitude completeness limit of |b| ≤ 5. The characteristics and the uncovered large-scale structures of this survey are described, in particular ...
