Chandra Detection of the First X-ray Forest along the Line of Sight To Mkn 421 (2005)
Nicastro, Fabrizio, Mathur, Smita, Elvis, Martin, Drake, Jeremy, Fiore, Fabrizio, Fang, Taotao, ...
We present the first >=3.5 sigma (conservative) or >=5.8 sigma (sum of lines significance) detection of two Warm-Hot Intergalactic Medium (WHIM) filaments at z>0, which we find along the line of...
Fruscione, Antonella, Greenhill, Lincoln J., Filippenko, Alexei V., Moran, James M., Herrnstein, James R., Galle, Elizabeth
We report monitoring of the 0.3-10 keV spectrum of NGC4258 with XMM over 1.5 years.We als o report reprocessing of an overlapping series of archival Chandra observations. By including earlier ASCA...
Four Years of Extreme Ultraviolet Observations of Markarian 421. I: Spectral Analysis (2000)
Cagnoni, Ilaria, Fruscione, Antonella
We analyzed the ~950 ks of spectroscopic data accumulated by the Extreme Ultraviolet Explorer (EUVE) satellite between 1994 and 1997 for the BL Lacertae object Markarian 421. The EUV spectrum is well...
Four Years of Extreme Ultraviolet Observations of Markarian 421: II. Temporal Analysis (2000)
Cagnoni, Ilaria, Fruscione, Antonella, Papadakis, Iossif E.
The Extreme Ultraviolet Explorer (EUVE) satellite accumulated ~one million seconds of public data between 1994 and 1997 for the BL Lacertae object Markarian 421. This is the second of two papers in...
Mrk421: EUVE observations from 1994 to 1997 (1998)
Cagnoni, Ilaria, Fruscione, Antonella, Papadakis, Iossif E.
We present spectral and timing analysis of all the data collected by the Extreme Ultraviolet Explorer for the BL Lac object Mrk 421 from 1994 to 1997. During these years Mrk 421 has been observed by...
A deep ROSAT Survey X: X-ray Luminous Narrow Emission Line Galaxies (1996)
Griffiths, Richard E., Della Ceca, Roberto, Georgantopoulos, Ioannis, Boyle, Brian J., Stewart, Gordon C., Shanks, Tom, ...
X-ray luminous narrow emision-line galaxies (NELG) have been previously identified and proposed as an important class of extragalactic X-ray sources, with a potentially significant contribution to...
