I. 1 Conditions for Doppler-like frequency shifts

Usual optics, spectroscopy, thermodynamics.

No “new physics” such as:

Dark matter

Dark energy

Inflation

...

I. 1. 1 Regular physics.

Coherent light-matter interactions:

Same interaction between any involved (molecular,...) dipole and the local involved electromagnetic fields.

Consequence:

From Huygens construction and Fresnel rules, if the number of involved molecules is large, the wave surfaces and images are clean.

5

I. 1. 2 No blurring of the images.

A monochromatic wave must be transformed into a single, frequency-shifted monochromatic wave.

If the interactions are scatterings:

-i) the scattered wave must interfere with the exciting wave into a single frequency wave. (from the coherence, these waves have the same wave surfaces)

- ii) ./.

6

I. 1. 3 No blurring of the spectra.

- ii) As the number of involved molecules is large, the

individual exchanges of energy are infinitesimal, not

quantified.

The molecules are perturbed by the waves to

non-stationary states and return to the initial stationary

state : it must be a parametric effect (i. e. matter is a

catalyst allowing interactions of the waves).

Several waves exchange energy while the molecules

are not (de)excited permanently.

The exchanges of energy must obey thermodynamics:

from hot beams, redshifted (usually light, from

Planck's law) to cold beams (usually radiofrequencies).

7

A strict constant relative frequency shift , as in a Doppler effect, is not required: Observed variations of are interpreted in the “big bang” theory by a variation of the fine structure constant.

8

I. 1. 4 (Nearly) constant relative

frequency shifts.

R

A continuous wave emitted by S is received at a lower

frequency by R. The number s-r of cycles (wavelengths)

between S and R increases : it is a Doppler effect.

Consequence: The theory of a Doppler-like effect must fail

using a CW source.

Corollary : A time-coherence parameter must appear in the

theory of a Doppler-like effect.

into a “dressed” (non stationary) state i

wave surfaces than the exciting wave.

i and W

j have the same symmetries.

Look at Coherent Raman Effects !

13

I

For coherent anti-Stokes scattering, (1) is replaced by:

E = E0[sin(t)(1-K') + K' sin((+t )] with K' > 0

= E0[sin(t)(1-K') + K' sin(t)cos(t) + K' sin(t)cos(t)]

K' is infinitesimal, and t is assumed small :E0[sin(t) + sin(K' t)cos(t) ]

E0[cos(K' t)sin(t) + sin(K' t)cos(t)] = E0 sin[(K' t] (3)

For Stokes scattering, K' is replaced by a negative K”. K'+K” is

proportional to exp(-h /2kT)-1, approximately to /T. Thus, the

frequency shift is proportional to K'+K”) T. (4)

As in refraction, the Ks are proportional to if the dispersions of the

polarisabilities are neglected. Thus is nearly constant.

14I. 2. 2 Replacing coherent Rayleigh scattering

(which produces refraction) by coherent Raman scattering.

● Low frequency Raman resonance.

The interactions starting at the beginning of a pulse, keeping t

small along a light impulsion, requires a Raman period larger

than the length of the impulsion, that is than the coherence time.

● Low pressure gas.

To avoid a destruction of the space coherence, the collisional time

must be longer than the coherence time.

We verify that “ultrashort” (i.e. “shorter than all relevant time

constants”) light pulses allow to keep the coherence.

(G. L. Lamb, Rev. Mod. Phys. 43, 99-124, 1971)

15I. 2. 3 Preservation of space-coherence :

Problem :

It cannot be any permanent exchange of energy between the molecules and the light because the molecules must return to their stationary state after the interaction ... It is necessary that the interaction involves several beams, so that the final balance of energy is zero for the molecules.

This coherent effect is “parametric”. The molecules act as a

catalyst.

The “Coherent Raman Effect on Incoherent Light”

(CREIL) is a SET of elementary coherent Raman effects

(followed by interference with the exciting beams) in which

transfers of energy obey thermodynamics .

CREIL effect

Lamb's conditions are fulfilled in any matter using femtosecond pulses; the coherence time of ordinary light is much longer (some nanoseconds).Long enough a collisional time requires a gas pressure generally lower than 1000 pascals.

The frequency of the required Raman resonance must be lower than

some MHz, but not too low (formula 4 : shift proportional to 2) to

produce strong CREIL effects. Such low frequencies are not

common, or they appear in states whose population is low.

Neutral atomic hydrogen has a too high Raman frequency (1420

MHz) in its ground state. It has convenient frequencies in the 2S1/2

states (178 MHz), in the 2P1/2

states (59 MHz) and in the 2P3/2

states

(24 MHz).

Hydrogen in these states will be noted H*.

18I. 2. 4 Application to astrophysics.

It is a quest for excited atomic hydrogen H*. As the CREIL effect increases the entropy of a set of simultaneously

refracted beams, we must search the temperature of these beams by

Planck's law. Usually, the high frequency beams are hot, therefore

redshifted; the thermal, radio beams are cold, blueshifted.

H* may be obtained:● Thermally around 100 000 K if a sufficient pressure forbids an

ionization.

● Around 15 000 K, with a Lyman pumping.

● By a cooling of a plasma.

Problem

Smaller periodicities are found (equivalent to Doppler shifts by a speed of 37km/s)

Look for similar computations with other molecules.

The transitions to different rotational levels of between convenientrovibronic states of H

2 may play the rôle of the Lyman transitions in

atomic hydrogen. But the spectrum of this ion is not well known.

H may be produced in the intergalactic H2 by UV radiation and its life time

is large at very low pressures.

May all «variations of physical constants» (fine structure, ration of massesp/e) be explained by the same CREIL dispersion?

III Applications to astrophysics

The cooling of the solar wind generates excited atomic hydrogen

beyond 5 UA; state 2S, it is stable (at low pressure) and efficient in CREIL.

Energy is transferred from light to radiofrequencies which are blueshifted (the blueshift being a heating of the thermal radiations)

- The blueshift is directly observed on the radio frequencies received from the probes Pioneer10 and 11.

27

III. 1. 1 Transfer of energy from

solar light to radio frequencies.

28

From Anderson et al. (2002)

Peter & Judge (1999) use the standard interpretation of the redshifts by

spicules or siphon flows, so that the shifts are supposed zero at the

limb, in contradiction with the lab or theoretical determinations.Accepting old frequencies, the shifts whose directions are opposite are

non-zero at the centre and large at the limb of the Sun.

The main function A of previous figure is considered as a product of functions B and C.

B corresponds to a CREILshifting the temperatures to a mean temperature (of HeI).

C corresponds to a reduction of the column density of excited hydrogen whose concentration, corresponding to its derivative D, is maximal around 100 000 K.

Problem: The temperature decreases with an increasing altitude while, in the chromosphere it increases.Can the previous result apply under the photosphere ?Under the photosphere, hydrogen is neutral atomic or dissociated.Atomic hydrogen is far from metallic state, the far UV energy is too low for a dissociation and too high for a Lyman absorption. Protons and electrons do not absorb: the gas is transparent.

Can the lines be sharp and the CREIL work at the high pressure ?Yes, the Galatry lineshape is sharper than the Doppler thermal lineshape in the low pressure gas.

Can the light cross the chromosphere ?Not easily, mainly through the spots where the ion H- is not abundant.

Can the photosphere emit the far UV lines ?Yes, by a Rayleigh incoherent scattering.

32

33

- Amplified (blueshifted) by all redshifts

- Made almost thermal (in particular isotropic) by a powerful (resonant) CREIL inside low frequencies

- Amplified, in particular by the redshift of the sun light beyond 5 UA (just as the radio from the Pioneer probes).

As the anisotropy of the corona, therefore of the wind is bound to the ecliptic, a part of the observed anisotropy of the CMB is bound to the ecliptic.

Arp's systems of quasars and galaxy.

These systems are surrounded by atomic hydrogen. The UV radiated by the quasars produces H*.As hydrogen is more excited close to the quasars, there is more H* on the path of the light from the quasars than from the galaxy.

Relation between quasars and galaxies.The “micro-quasars” found in our galaxy are neutron stars which have the radio spectrum of the quasars and move quickly.If there is more hydrogen around our galaxy than inside, they become “isolated quasars” when they leave it, their repartition is isotropic.The other quasars are bound to their own galaxies.

36

37

The VROs are generally close to the quasars : the far UV

emitted by the quasars (or similar objects) creates excited

atomic hydrogen which produces a CREIL effect.

It seems that these objects are surrounded by hot dust (up

to 100K) whose stability is a problem. It is probably not

dust, but the CREIL counterpart of the redshifts.

.

III. 3. 2. The “Very Red Objects”

38

As the galaxies are closer than in the standard theory, they

are smaller, so that there is no need of dark matter or other

gravitational effect to explain their stability.

.

III. 3. 3 No need of dark matter

39Conclusion:

It is clear that “anomalous” redshifts are observed

where the physico-chemical conditions favour the

creation of neutral atomic hydrogen in states 2S

and 2P.

Too simple, general and beautiful (a magic stick !)

to be completely wrong.

A good rule should be:

Search for excited atomic hydrogen.
