Opacity effect on core-shift and the spectral properties of jets
R. Sharma, M. Massi, G. Torricelli-Ciamponi
There is theoretical and observational evidence that the jet core position changes with frequency. However, the core position for a given frequency may vary with time in the case o…
Radio/X-ray correlations and variability in the X-ray binary LS I +61°303
R. Sharma, M. Massi, M. Chernyakova +6
The high-mass X-ray binary LS I +61°303 exhibits variability in its radio and X-ray emissions, ranging from minute to hour time-scales. At such short time-scales, not much is known…
Evidence for periodic accretion-ejection in LSI+61303
M. Massi, M. Chernyakova, A. Kraus +7
The stellar binary system LS I +61303, composed of a compact object in an eccentric orbit around a B0 Ve star, emits from radio up to gamma-ray energies. The orbital modulation of…
Simultaneous long-term monitoring of LS I +61°303 by OVRO and Fermi-LAT
Frederic Jaron, Maria Massi, Sebastian Kiehlmann +1
Previous long-term monitorings of the gamma-ray-loud X-ray binary LS I +61°303 have revealed the presence of a long-term modulation of ~4.5 years. After nine years of simultaneous…
Hour time-scale QPOs in the X-ray and radio emission of LS I +61303
Silvia Nösel, Richa Sharma, Maria Massi +2
LS I +61303 is an X-ray binary with a radio outburst every ~27 days. Previous studies of the stellar system revealed radio microflares superimposed on the large radio out…
Revisiting LS I +61 303 with VLBI astrometry
Y. W. Wu, G. Torricelli-Ciamponi, M. Massi +4
We conducted multi-epoch VLBA phase reference observations of LS I +61 303 in order to study its precessing radio jet. Compared to similar observations in 2006, we find that the ob…
