- High energy astrophysics, AP.JP
Abstract
An exciting unsolved problem in the study of high energy processes of early type stars is the physical mechanism for producing hard-thermal X-rays of moderate luminosity near the Be star gamma Cassiopeiae (gCas). The nature of such emission is currently a matter of controversy, but the two proposed interpretations imply in a breakthrough in the physics of massive stars: (i) a single-Be ...

- Nature and properties of fossil groups, BP.PD
Abstract
Fossil Groups (FGs) are groups of galaxies dominated by a giant elliptical galaxy, which is most likely a result from a merger of luminous galaxies (with L ~ L*). The nature and properties of FGs are not well known. There has been a lot of recent interest of the astronomical community on fossil groups, due to the challenges they represent - notably, on the "small scale dark matter mode...
