An extended Lyman outflow from a radio galaxy at z=3.7?
Miguel Coloma Puga, Barbara Balmaverde, Alessandro Capetti +5
Spatially resolved observations of AGN host galaxies undergoing feedback processes are one of the most relevant avenues through which galactic evolution can be studied, given the l…
HST/COS observations of the newly discovered obscuring outflow in NGC 3783
G. A. Kriss, M. Mehdipour, J. S. Kaastra +24
To understand the nature of transient obscuring outflows in active galactic nuclei, we observed the Seyfert 1 galaxy NGC 3783 on two occasions in December 2016 triggered by Swift m…
AGB candidates in the field of gamma Cas
Roberto Nesci, Taavi Tuvikene, Corinne Rossi +5
We report the spectroscopic and photometric monitoring of a sample of 530 candidate AGB stars in a 5 degrees field, selected from the IPHAS catalog: historic light curves were deri…
Feeding and feedback in the powerful radio galaxy 3C 120
F. Tombesi, R. F. Mushotzky, C. S. Reynolds +8
We present the spectral analysis of a 200~ks observation of the broad-line radio galaxy 3C~120 performed with the high energy transmission grating (HETG) spectrometer on board the…
X-ray evidence for ultra-fast outflows in local AGNs
F. Tombesi, M. Cappi, R. M. Sambruna +4
X-ray evidence for ultra-fast outflows (UFOs) has been recently reported in a number of local AGNs through the detection of blue-shifted Fe XXV/XXVI absorption lines. We present th…
Spectral catalogue of bright gamma-ray bursts detected with the BeppoSAX/GRBM
C. Guidorzi, M. Lacapra, F. Frontera +5
The emission process responsible for the so-called "prompt" emission of gamma-ray bursts is still unknown. A number of empirical models fitting the typical spectrum still lack a sa…
