X-ray Emission of Mkn 421: New Clues From Its Spectral Evolution. II. Spectral Analysis and Physical Constraints
G. Fossati, A. Celotti, M. Chiaberge +7
Mkn 421 was repeatedly observed with BeppoSAX in 1997-1998. The source showed a very rich phenomenology, with remarkable spectral variability. This is the second of two papers pres…

X-ray Emission of Mkn 421: New Clues From Its Spectral Evolution. I. Temporal Analysis
G. Fossati, A. Celotti, M. Chiaberge +7
Mkn 421 was repeatedly observed with BeppoSAX in 1997-1998. This is the first of two papers where we present the results of a thorough temporal and spectral analysis of all the dat…
