Models of galaxy formation and evolution within the Ю?-CDM paradigm can be tested against their predictions on the number and properties of dwarf galaxies and in particular stellar systems highly dominated by dark matter. ... The authors argue that the third possibility is the most likely one and hence SECCO1 would be a new faint dwarf galaxy residing in the Virgo cluster of galaxies. ...

Observations over the last decade indicate black-holes likely resided at the heart of most if not all galaxies. The correlation between the masses of these compact nuclear sources and their host galaxy is poorly understood and likely plays an important role in the formation and evolution, of at least the most massive systems, due to AGN feedback. ...

Without an optical afterglow, a galaxy within the 2 arc second error region of a GRB x-ray afterglow is identified as a host galaxy; however confusion can rise due to the facts that 1. the edge of a galaxy is diffused, 2. multiple sources could exist within 2 arc second error region, 3.the distance between the galaxy and the x-ray afterglow is measured by projection, and 4. lensing causes increase of brightness and position shifts. ...
