A supernova origin for dust in a high-redshift quasar
R. Maiolino, R. Schneider, E. Oliva +5
Interstellar dust plays a crucial role in the evolution of the Universe by assisting the formation of molecules, by triggering the formation of the first low-mass stars, and by abs…
Nuclear star formation in the quasar PG1126-041 from adaptive optics assisted spectroscopy
G. Cresci, R. Maiolino, A. Marconi +2
We present adaptive optics assisted spectroscopy of three quasars obtained with NACO at VLT. The high angular resolution achieved with the adaptive optics (~0.08"), joined to the d…
Warm-Hot Intergalactic Medium in the Sculptor Supercluster
L. Zappacosta, R. Maiolino, F. Mannucci +2
We have analyzed the soft X-ray emission in a wide area of the Sculptor supercluster by using overlapping ROSAT PSPC pointings. After subtraction of the point sources we have found…
Detections of Warm-Hot Intergalactic Medium
L. Zappacosta, R. Maiolino, F. Mannucci +3
Several popular cosmological models predict that most of the baryonic mass in the local universe is located in filamentary and sheet-like structures associated with groups and clus…
