of coherent circular motion of the centroid of emission during infrared flares lends new insight into the geometry and physical properties of matter in the accretion flow, as well

Likewise, the optical and NIR spectrum is well described by the thermal emission from the viscous accretion disk, with an excess due to the synchrotron emission from the jet,

So as to compare both methods, the digital hologram is reconstructed using the discrete Fresnel transform with (K,L)0(2048,2048) and with the convolution method so that (K,L)

La présence de l’onde de densité de charge à ces pressions permet alors de mesurer dans un état de coexistence, comme c’est le cas pour 2H-NbSe 2 à pression ambiante, et

Pour concevoir des interventions appropriées en vue d’enrayer la stigmatisation et d’améliorer la qualité des services de première ligne, nous devons mieux comprendre les

To answer this question, we will derive site-specific power laws relating the horizontal travel distance ∆L 0 to the unstable volume V, using a purely empirical approach, a

AMBER is a near infrared, three beams, dispersed fringes, single mode VLTI focal instrument.. Besides a very wide scientific program, the near infrared, and particularly the K
