Stellar population in bulge of spiral galaxies

Saglia, R. P.; Morelli, L.; Corsini, E. M. +6 more

We present a preliminary analysis of ASTRO-F data of a complete sample of ~150 EROs (R-K>5) down to K(Vega)<19, for which reliable photometric redshifts are available, in the range 0.8<z<2, selected over two fields (S7 and S2) of the MUNICS survey. The area covered is about 420 arcmin^2. We have imaged this area with AKARI telescope in…

Dust scattering X-ray expanding rings around gamma-ray bursts

Tiengo, A.; Mereghetti, S.; Vianello, G.

Scattering by dust grains in our Galaxy can produce X-ray halos, visible as expanding rings, around GRBs. This has been observed in three GRBs to date, allowing to derive accurate distances for the dust clouds as well as some constraints on the prompt GRB X-ray emission that was not directly observed. We developed a new analysis method to study du…
