Fundamental Parameters of the Milky Way Galaxy Based on VLBI Astrometry [PDF]
Publications of the Astronomical Society of Japan, 2012 We present analyses to determine the fundamental parameters of the Galaxy based on VLBI astrometry of 52 Galactic maser sources obtained with VERA, VLBA, and EVN. We model the Galaxy's structure with a set of parameters, including the Galaxy center distance $ R_0$ , the angular rotation velocity at the LSR $ \Omega_0$ , the mean peculiar motion of the ...

Fundamental parameters of isolated galaxy triplets in the local universe: statistical study [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 Understanding the dynamics of galaxy triplet systems is one of the significant ways of obtaining insight into the dynamics of large galaxy clusters. Toward that aim, we present a detailed study of all isolated triplet systems (total of 315) taken from the `SDSS-based catalogue of Isolated Triplets' (SIT). In addition, we compared our results with those

Fundamental parameters of FR II radio galaxies and their impact on groups and clusters' environments [PDF]
Astronomische Nachrichten, 2013 AbstractRadio galaxies are among the largest and most powerful single objects known and are found at variety of redshifts, hence they are believed to have had a significant impact on the evolving Universe. Their relativistic jets inject considerable amounts of energy into the environments in which the sources reside; thus the knowledge of the ...

Surface density: a new parameter in the fundamental metallicity relation of star-forming galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 Star-forming galaxies display a close relation among stellar mass, metallicity and star-formation rate (or molecular-gas mass). This is known as the fundamental metallicity relation (FMR) (or molecular-gas FMR), and it has a profound implication on models of galaxy evolution.

Fundamental galaxy parameters for radio-loud active galactic nuclei and the black hole-radio power connection [PDF]
Monthly Notices of the Royal Astronomical Society, 2003 We have determined the central velocity dispersions and surface brightness profiles for a sample of powerful radio galaxies in the redshift range 0.06 < z < 0.31, which were selected on the basis of their young radio source. The optical hosts follow the fundamental plane of elliptical galaxies, showing that young radio sources reside in normal ...

Fundamental parameters of brightest cluster galaxies
The Astrophysical Journal, 1991 Photometry and spectroscopy of a sample of the brightest cluster galaxies (BCGs) are presented, and the relationships between scale length, surface brightness, velocity dispersion, and line strength are determined and compared with the relations determined for lower luminosity ellipticals (LLEs).
