We have analyzed long-slit spectroscopic data for a sample of 12 tidally disturbed elliptical galaxies. The spectra were obtained with the Kitt Peak National...

PublicationInteracting binary galaxies. V - NGC 4782/4783 (3C 278): Unbound colliders, not a supermassive pair
The authors have determined the masses and orbital parameters for the galaxies in the strongly interacting binary NGC 4782/4783 by finding a numerical...

PublicationInteracting binary galaxies. VI - The fast encounter of NGC 2672 and NGC 2673 (Karachentsev 175, ARP 167)
The isolated pair of interacting ellipticals NGC 2672/2673 (Arp 167; Karachentsev 175), whose line-of-sight relative velocity is about 520 km/s, is studied...

PublicationInteraction versus radio source generation - The properties of radio jet parent galaxies
This paper presents the first systematic survey at optical wavelengths of galaxies with detected radio jets using CCD imaging. About 50 percent of the sample of...

PublicationIntermediate-resolution spectropolarimetry of 3C 273
Spectropolarimetric observations of the quasar 3C 273 over the range 3200-8000 A show wavelength-dependent polarization in the continuum, while the lines had no...

PublicationIntermediate-resolution spectropolarimetry of a small sample of quasars
We present spectropolarimetric observations of a sample of three quasars selected because of their very different broad-band polarization properties. All of the...

PublicationInversion of Stokes profiles
An inversion code of Stokes line profiles is presented. It allows the recovery of the stratification of the temperature, the magnetic field vector, and the line...

PublicationLi abundances in late-type companions to neutron stars and black hole candidates
Following our recent report of a strong Li lambda 6708 resonance line in the secondary of the black hole candidate V404 Cyg, we present here its detection in...

PublicationLi depletion in F stars by internal gravity waves
It is argued that internal gravity waves generated by the convective envelope of a star may be effective in producing a weak mixing in its radiative interior...
