The search for structure in the cosmic microwave background (CMB) needs to take into account the Galactic background contribution. The potential of using...

A wide variety of Galactic sources show transient emission at soft and hard X-ray energies: low- and high-mass X-ray binaries containing compact objects...

Bellazzini et al. claim that López-Corredoira et al. warp model is totally unable to reproduce the Canis Major structure in the red clump stars. However, slight...

The diffuse soft X-ray emissivity from galactic winds is computed during the Epoch of Reionization (EoR). We consider two analytic models, a pressure-driven...

Massive early-type galaxies follow a tight relation between the mass of their central supermassive black hole (MBH) and their stellar mass (M⋆). The origin of...

We present the first results of hydrodynamical simulations that follow the formation of galaxies to the present day in nearly spherical regions of radius ~20h...

We present a catalogue of 348 galaxy clusters and groups with 0.2 z 1.2 selected in the 2.78 deg2 Advanced Large, Homogeneous Area Medium Band Redshift...

The triggering mechanism for the most luminous, quasar-like active galactic nuclei (AGN) remains a source of debate, with some studies favouring triggering via...

We show that recently documented trends in galaxy sizes with mass and redshift can be understood in terms of the influence of underlying cosmic evolution; a...
