Rejuvenation triggers nuclear activity in nearby galaxies
Feedback, in particular from active galactic nuclei (AGNs), is believed to play a crucial role in the evolution of galaxies. In the local Universe, many...
Relation between photospheric magnetic field and chromospheric emission
Aims: We investigate the relationship between the photospheric magnetic field and the emission of the mid chromosphere of the Sun. Methods: We simultaneously...
Relation between the ionizing continuum and the emission lines in Fairall 9
The evolution of the emission line ratios of a photoionized cloud described by standard BLR parameters which is exposed to a varying ionizing continuum is...
Relation of internal attenuation, dust emission, and the size of spiral galaxies. Calibration at low-z and how to use it as a cosmological test at high-z
Aims: Dust in spiral galaxies produces emission in the far-infrared (FIR) and internal absorption in visible wavelengths. However, the relation of the two...
Relations among structural parameters in barred galaxies with a direct measurement of bar pattern speed
We investigate the relations between the properties of bars and their host galaxies in a sample of 77 nearby barred galaxies, spanning a wide range of...
Relationship between Hubble Type and Spectroscopic Class in Local Galaxies
We compare the Hubble type and the spectroscopic class of the galaxies with spectra in the Sloan Digital Sky Survey Data Release 7. As has long been known...
Relationships between cluster densities and other statistical quantities.
We present a procedure for obtaining the cluster densities in terms of the probability, P_n_(r), for a randomly placed sphere of radius r to contain n galaxies...
Relationships between magnetic foot points and G-band bright structures
Aims:Magnetic elements are thought to be described by flux tube models, and are well reproduced by MHD simulations. However, these simulations are only...
