Gravity field outside the earth, galaxies, the spectral characteristics are very diferent to those of the DIG in spiral galaxies: the excitation is higher and the [SII/Hα] much lower. A combination of leakage photoionization models plus shocks will be able to explain these characteristics.

Local Group(s)he M81 group, the CenA group, and the IC 342/Maffei group – are in many respects Local Group analogs: Their luminosity functions, galaxy content, fractional galaxy type distribution, crossing times, masses, and zero-velocity surface radii are similar to those of the Local Group. Also, the nearby gro

Properties of RR Lyrae Stars in the Inner Regions of the Large Magellanic Cloud. II. The Extended Saield and 13 in the clusters NGC1835 and NGC2019. 15 RR Lyrae stars of .Cen were observed as well for comparison. We measured radial velocities for 87 LMC RR Lyrae, and metallicities for 78 RR Lyrae, nearly tripling the previous sample. These targets are located in 11 fields covering a wide range of

10mass clusters and groups, drawn from a new 400 deg. X-ray serendipitous survey of Clusters of Galaxies. The aim is to establish robust determinations of the baryon contents in these low-mass systems, and to determine if there is a baryon deficit compared to CMB observations.
