    Departures from axial symmetry, and starburst activity, in the bulge of NGC 4736

    Evidence for circumnuclear starbursts in spiral galaxies can take the form of a blue excess near the nucleus, but more frequently (because of dust extinction) H...

    General relativistic influence on emission line variation in broad-line region

    The present examination of general relativistic effect on the lag time between continuum and emission line variations in the broad line notes that in the case...

    Microlensing events of the LMC are better explained by stars within the LMC than by MACHOs

    The recently reported microlensing events of the Large Magellanic Cloud (LMC) have caused much excitement, and have been interpreted as due to 'dark objects'...

    Radiation-induced forces on the orbits of dust particles around rotating stars

    The influence of rotation and finite size of the radiation source on the orbits of dust particles around stars is analyzed. It is found that there are physical...

    Satellite galaxies as probes of the gravitational potentials of large spirals

    An aspect of the missing mass problem in galaxies, not easy to address, is whether the dynamical mass distribution is spherical or greatly flattened, following...

    The 160 minute solar oscillation - an artifact?

    Analysis of data obtained over the years 1980-1985 are analyzed to show that the period of the 160-minute signal is indeed 160.00 minutes. It is demonstrated...
