The onset of X-ray emission in young stellar objects: a Chandra observation of the Serpens star-forming region
G. Giardino, F. Favata, G. Micela +2
AIMS: To study the properties of X-ray emissions from young stellar objects (YSOs), through their evolution from Class I to Class III and determine whether Class 0 protostars emit…
ROSAT-HRI investigation of the NGC 507 X-ray halo
M. Paolillo, G. Fabbiano, G. Peres +1
We present an X-ray investigation of the elliptical galaxy NGC 507. We make use of archival Rosat HRI, PSPC and Chandra data, to connect the large-scale structure of the halo to th…
Testing Comptonisation models using BeppoSAX observations of Seyfert 1 galaxies
P. O. Petrucci, F. Haardt, L. Maraschi +7
We have used realistic Comptonization models to fit high quality BeppoSAX data of 6 Seyfert galaxies. Our main effort was to adopt a Comptonization model taking into account the an…
1H0419-577: A "two-state" soft X-ray Seyfert galaxy
M. Guainazzi, A. Comastri, G. M. Stripe +8
In this paper we report on the first simultaneous optical and X-ray (Beppo-SAX) observations of the radio-quiet AGN 1H0419-577. The optical spectrum clearly leads us to classify th…
