Evidence for Intrinsic Redshifts in Normal Spiral Galaxies
The Tully-Fisher Relationship (TFR) is utilized to identify anomalous
redshifts in normal spiral galaxies. Three redshift anomalies are identified in
this analysis: (1) Several clusters of galaxies are examined in which late type
spirals have significant excess redshifts relative to early type spirals in the
same clusters, (2) Galaxies of morphology similar to ScI galaxies are found to
have a systematic excess redshift relative to the redshifts expected if the
Hubble Constant is 72 km s-1 Mpc-1, (3) individual galaxies, pairs, and groups
are identified which strongly deviate from the predictions of a smooth Hubble
flow. These redshift deviations are significantly larger than can be explained
by peculiar motions and TFR errors. It is concluded that the redshift anomalies
identified in this analysis are consistent with previous claims for large
non-cosmological (intrinsic) redshifts.Comment: Accepted for publication at Astrophysics&Space Science. 36 pages

The Surroundings of Disturbed, Active Galaxies
The brightest apparent magnitude examples of ultra luminous infrared galaxies
(ULIRG's) are studied here in X-ray, optical, infrared and radio wavelengths.
It is is found that they have associated material reaching out to apparent
diameters of the order of a degree on the sky.
Gas, dust, X-ray material and quasars appear to be ejected from the active
nuclei with all objects nearer than their redshift distances.Comment: 14 pages, Figs. 1-28 jpg and gif file
Elektrostatska energija međudjelovanja i faktor 1.23
The factor F ≈ 1.23 has originally been found in the redshift of quasars. Recently, it has been found in very different physical phenomena: the life-time of muonium, the masses of elementary particles (leptons, quarks,...), the correlation of atomic weight (A) and atomic number (Z) and the correlation of the sum of masses of all orbiting bodies with the mass of the central body in gravitational systems. In this work, we describe further systems where the factor F appears, the distributions of electric charges. We consider the electrostatic interaction between various pairs of charge distributions: two uniformly charged spheres, a point charge and a uniformly charged sphere, two point charges, a point charge and an infinite uniform line charge, two parallel uniform infinite line charges and two infinite parallel plane charge distributions.Crveni su pomaci kvazara prvotno ukazali na faktor F ≈ 1.23. Nedavno se je našao i u vrlo različitim sustavima, uključujući poluživot muonija, mase elementarnih čestica (leptoni, kvarkovi, ...), odnos atomskih težina (A i atomskih brojeva (Z) i odnos zbroja svih kružećih masa s centralnom masom u gravitacijskim sustavima. U ovom radu opisujemo još neke sustave u kojima se također pojavljuje faktor F, a to su elektrostatski sustavi niza raspodjela električnih naboja: dvije jednoliko površinski nabijene kugle, točkast naboj i jednoliko nabijena kugla, dva točkasta naboja, točkast naboj i jednolika beskonačna pravocrtna raspodjela naboja, dvije usporedne jednolike beskonačne pravocrtne raspodjele naboja i dvije usporedne jednoliko nabijene ravnine
Intrinsic Redshifts and the Tully-Fisher Distance Scale
The Tully-Fisher relationship (TFR) has been shown to have a relatively small
observed scatter of ~ +/-0.35 mag implying an intrinsic scatter < +/-0.30 mag.
However, when the TFR is calibrated from distances derived from the Hubble
relation for field galaxies scatter is consistently found to be +/-0.64 to
+/-0.84 mag. This significantly larger scatter requires that intrinsic TFR
scatter is actually much larger than +/-0.30 mag, that field galaxies have an
intrinsic TFR scatter much larger than cluster spirals, or that field galaxies
have a velocity dispersion relative to the Hubble flow in excess of 1000 km
s-1. Each of these potential explanations faces difficulties contradicted by
available data and the results of previous studies. An alternative explanation
is that the measured redshifts of galaxies are composed of a cosmological
redshift component predicted from the value of the Hubble Constant and a
superimposed intrinsic redshift component previously identified in other
studies. This intrinsic redshift component may exceed 5000 km s-1 in individual
galaxies. In this alternative scenario a possible value for the Hubble Constant
is 55-60 km s-1 Mpc-1.Comment: 15 pages, Astrophysics&Space Science - Accepted for publicatio
The Wolf effect and the Redshift of Quasars
We consider a simple model, based on currently accepted models for active
galactic nuclei, for a quasi-stellar object (QSO or ``quasar'') and examine the
influence that correlation- induced spectral changes (``The Wolf Effect'') may
have upon the redshifts of the optical emission lines.Comment: 13 pages, 3 figures. To be published in J. European Optical Soc. A:

Arp 302: Non-starburst Luminous Infrared Galaxies
Arp 302, a luminous infrared source (L_{IR} = 4.2x10^{11} Lsun), consisting
of two spiral galaxies (VV340A and VV340B) with nuclear separation of 40'', has
the highest CO luminosity known. Observations with the BIMA array at 5'' X 7''
resolution reveal that the CO emission is extended over 23.0 kpc in the edge-on
spiral galaxy, VV340A, corresponding to 6.7x10^{10} Msun of H_2. In the
companion face-on galaxy, VV340B, the CO emission is extended over ~10.0 kpc,
with 1.1x10^{10} Msun of H_2. The large CO extent is in strong contrast to
starburst systems, such as Arp 220, in which the CO extent is typically 1
kpc. Furthermore, (H_2) is found to be 6.0 Lsun/Msun throughout
both galaxies. Thus the high IR luminosity of Arp 302 is apparently not due to
starbursts in the nuclear regions, but is due to its unusually large amount of
molecular gas forming stars at a rate similar to giant molecular clouds in the
Milky Way disk. Arp 302 consists of a pair of very gas-rich spiral galaxies
that may be interacting and in a phase before a likely onset of starbursts.Comment: AAS Latex plus two postscript figures. ApJ Letters (accepted
