On the nature and Galactic origin of the Be binary MWC 656. New insights from VLA, Gaia, and Fermi-LAT
Sergio A. Dzib, Frederic Jaron
The binary star MWC 656 was initially proposed as the first confirmed system composed of a Be star and a black hole. However, recent studies have challenged this interpretation, su…
IceCube AGN Neutrino candidate PKS 1717+177: Dark deflector bends nuclear jet
S. Britzen, A. B. Kovačević, M. Zajaček +8
The BL Lac Object PKS 1717+177 has been identified as potential neutrino-emitting AGN in the point source stacking analysis of IceCube data. We explore peculiarities in the morphol…
Owens Valley Radio Observatory monitoring of LS I +61°303 completes three cycles of the super-orbital modulation
F. Jaron, S. Kiehlmann, A. C. S. Readhead
The high-mass X-ray binary LS I +61°303 is composed of a Be-type star and a compact object. The emission is variable and periodic across the electromagnetic spectrum, from radio to…
Precession-induced Variability in AGN Jets and OJ 287
Silke Britzen, Michal Zajaček, Gopal-Krishna +5
The combined study of the flaring of Active Galactic Nuclei (AGN) at radio wavelengths and pc-scale jet kinematics with Very Long Baseline Interferometry (VLBI) has led to the view…
Rapid X-ray variability of the gamma-ray binary LS I+61 303
J. Lopez-Miralles, Sara E. Motta, S. Migliari +1
The gamma-ray binary LS I+61 303 has been widely monitored at different wavelengths since its discovery more than sixty years ago. However, the nature of the compact object and the…
A Precessing Jet Scenario for the Multi-Wavelength Long-Term Modulation of LS I +61303
Frederic Jaron
The high-mass X-ray binary LS I +61303 is detected across the electromagnetic spectrum from radio until the very high energy gamma-ray regime. The emission is not only high…
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…
Radio QPO in the -ray-loud X-ray binary LS I +61303
Frederic Jaron, Richa Sharma, Maria Massi +5
LS I +61303 is a -ray emitting X-ray binary with periodic radio outbursts with time scales of one month. Previous observations have revealed microflares superimposed o…
Understanding the periodicities in radio and GeV emission from LS I+61303
F. Jaron, G. Torricelli-Ciamponi, M. Massi
Accretion models predict two ejections along the eccentric orbit of LS I +61 303: one major ejection at periastron and a second, lower ejection towards apastron. We develop a physi…
Radio Emission from the Be/Black Hole Binary MWC 656
S. A. Dzib, M. Massi, F. Jaron
Context. MWC 656 is the recently discovered first binary system case composed of a Be-type star and an accreting black hole. Its low X-ray luminosity indicates that the system is i…
The apparent discontinuity in the periodicity of the GeV emission from LS I +61°303
Frederic Jaron, Maria Massi
The gamma-ray binary LS I +61°303 shows a discontinuity of the periodicity in its GeV emission. In this paper, we show that during the epochs when the timing analysis fails to dete…
Long-term OVRO monitoring of LSI+61303: confirmation of the two close periodicities
M. Massi, F. Jaron, T. Hovatta
Context: The gamma-ray binary LSI+61303 shows multiple periodicities. The timing analysis of 6.7 yr of GBI radio data and of 6 yr of Fermi-LAT GeV gamma-ray data both have found tw…
Discovery of a periodical apoastron GeV peak in LS I +61°303
F. Jaron, M. Massi
Aims. The aim of this paper is to analyse the previously discovered discontinuity of the periodicity of the GeV -ray emission of the radio-loud X-ray binary LS I +61°303 and to…
