Yes, some "flares" seem little and intense, other less intense and diffuse
(about 1'-2')

I know this effects and your explanation as a relativistic effect, but the
problem is that any body know the effects of an intense garvitational field
and the magnetic field producted by the electrons of the relativistic jets.

I know that other questions regarding the collimation process of the flux
and the direction (some time perpendicular at the plan of the accretion
disk, some time parallel)
Also, what happened when an intense magnetic field is submit a fast
rotation? Seem that the sincrotron radiation is the cause of the intense
emission in
several band, but is not possible to exclude other
causes (what?) of emission in the extreme high energy conditions as
SGRV4641.

At this moment I am not been able to produce a revolution in modern phisics,
but I am been able to understand that some astrophisical process as SS433,
collimation of the  flux of the jets  in Young Stellar Ojects etcc..,
etcc...,
not can to be explain if in the models
is not introducted the magnetic field and your effects.
But this, I know, complicate the sets of differential equations to resolve.

Also, I think, that is again more complicate in the case of magnetic field
associated ad an intense gravitational field and a fast motion and/or
rotation
of the sources as SGRV4641 (black-hole with a close companion)

For this I not exclude the possibilty that the actual quantum theory
and theory of the relativity are not sufficient to explain
some observations.


Yet, actually the problem is: CCD is able to detect an ultra.short-term
flash and discern it by the total brightness of the source?

Because I Have noted that the "ipothetics intense flare" have an intense blu
coulor, someone is able to made a sets of
CCD observations with this filter?
