Upper limits on the mass of supermassive black holes from STIS archival data
A. Beifiori, E. M. Corsini, E. Dalla Bonta' +4
The growth of supermassive black holes (SMBHs) appears to be closely linked with the formation of spheroids. There is a pressing need to acquire better statistics on SMBH masses, s…
The Physical Properties of LBGs at z>5: Outflows and the "pre-enrichment problem"
M. D. Lehnert, M. Bremer, A. Verma +2
We discuss the properties of Lyman Break galaxies (LBGs) at z>5 as determined from disparate fields covering approximately 500 sq. arcmin. While the broad characteristics of the LB…
HST's view of the youngest massive stars in the Magellanic Clouds
M. Heydari-Malayeri, M. R. Rosa, V. Charmandaris +5
Accurate physical parameters of newborn massive stars are essential ingredients to shed light on their formation, which is still an unsolved problem. The rare class of compact H II…
A longer XMM-Newton look at I Zwicky 1: physical conditions and variability of the ionised absorbers
E. Costantini, L. C. Gallo, W. N. Brandt +2
We present a spectral analysis of the narrow-line Seyfert 1 galaxy I Zwicky 1, focusing on the characteristics of the ionised absorbers as observed with XMM-Newton in 2005. The sof…
The micro-Jy Radio Source Population: the VLA-CDFS View
P. Padovani, V. Mainieri, P. Tozzi +5
We analyse the 267 radio sources from our deep (flux limit of 42 microJy at the field center at 1.4 GHz) Chandra Deep Field South 1.4 and 5 GHz VLA survey. The radio population is…
The XMM-Newton Slew Survey
A. M. Read, R. D. Saxton, M. P. Esquej +2
XMM-Newton, with the huge collecting area of its mirrors and the high quantum efficiency of its EPIC detectors, is the most sensitive X-ray observatory ever flown. This is striking…
