In this work, we study the physical and kinematical properties of the emission line region of the Seyfert 1.5 galaxy Mrk 817 using three sets of observations...
Complex ionization structure and kinematics in the circumnuclear region of NGC 3227
We present bidimensional spectroscopy of the circumnuclear region of the Seyfert galaxy NGC 3227. The physical and kinematical characteristics of the two...
Complex K: Supernova Origin of Anomalous-velocity H I Structure
We address one of the lingering mysteries of high-velocity clouds: If the anomalous negative velocities are the result of the approaching gas from old...
Complex particle acceleration processes in the hotspots of 3C 105 and 3C 445
We investigate the nature of the broad-band emission associated with the low-power radio hotspots 3C 105 South and 3C 445 South. Both hotspot regions are...
Component masses of young, wide, non-magnetic white dwarf binaries in the Sloan Digital Sky Survey Data Release 7
We present a spectroscopic component analysis of 18 candidate young, wide, non-magnetic, double-degenerate binaries identified from a search of the Sloan...
Composite analysis with Monte Carlo methods: an example with cosmic rays and clouds
The composite (superposed epoch) analysis technique has been frequently employed to examine a hypothesized link between solar activity and the Earth's...
Composite bulges - II. Classical bulges and nuclear discs in barred galaxies: the contrasting cases of NGC 4608 and NGC 4643
We present detailed morphological, photometric, and stellar-kinematic analyses of the central regions of two massive, early-type barred galaxies with nearly...
Composite Bulges. III. A Study of Nuclear Star Clusters in Nearby Spiral Galaxies
We present photometric and morphological analyses of nuclear star clusters (NSCs)-very dense, massive star clusters present in the central regions of most...
Composite bulges: the coexistence of classical bulges and discy pseudo-bulges in S0 and spiral galaxies
We present an analysis of nine S0-Sb galaxies which have (photometric) bulges consisting of two distinct components. The outer component is a flattened...
