The connection between AGN and their host galaxies has been widely
studied over recent years, showing it to be of great importance for
providing answers to some fundamental questions related with AGN fueling
mechanisms, their formation and evolution. Using X-ray and one of the
deepest broad-band optical data sets, we studied morphology and colours
in relationship with X-ray properties for sources at redshifts z <
2.0, using a sample of 262 AGN in the Subaru/XMM-Newton Deep Survey
(SXDS). Morphological classification was obtained using the galSVM code,
one of the new methods useful…
In this work we analyze the physical properties of a sample of 56
spectroscopically selected star-forming (SF) Ly$\alpha$ emitting
galaxies at 2.0$\lesssim$z$\lesssim$3.5 using both a spectral energy
distribution (SED) fitting procedure from rest-frame UV to mid-IR and
direct 160$\mu$m observations taken with the Photodetector Array Camera
& Spectrometer (PACS) instrument onboard \emph{Herschel Space
Observatory}. We define LAEs as those Ly$\alpha$ emitting galaxies whose
rest-frame Ly$\alpha$ equivalent widths (Ly$\alpha$ EW$_{rest-frame}$)
are above 20\AA, the typical threshold in…
Lo scorso 3 febbraio 2012 c’è stata una grande nevicata nel centro Italia. Anche Frasso Sabino è stato travolto dai fiocchi. Qui troverete alcune immagini del nostro osservatorio in una configurazione “particolare”.
Tutte le foto sono state scattate da Raniero Albanesi.
