Active Galactic Nuclei: Sources for ultra high energy cosmic rays?
P. L. Biermann, J. K. Becker, L. Caramete +11
The origin of ultra high energy cosmic rays promises to lead us to a deeper understanding of the structure of matter. This is possible through the study of particle collisions at c…
Pattern Speeds and Galaxy Morphology
R. Buta, X. Zhang
The morphology of a disk galaxy is closely linked to its kinematic state. This is because density wave features are likely made of spontaneously-formed modes which are allowed to a…
VLT/ISAAC Spectra of the Hbeta Region in Intermediate-Redshift Quasars III. Hbeta Broad Line Profile Analysis and Inferences about BLR Structure
P. Marziani, J. W. Sulentic, G. M. Stirpe +2
[Abridged] We present new VLT ISAAC spectra for 30 quasars, which we combine with previous data to yield a sample of 53 intermediate redshift (z ~ 0.9 - 3.0) sources. The sample is…
Dynamical Simulations of NGC 2523 and NGC 4245
P. Treuthardt, H. Salo, R. Buta
We present dynamical simulations of NGC 2523 and NGC 4245, two barred galaxies (types SB(r)b and SB(r)0/a, respectively) with prominent inner rings. Our goal is to estimate the bar…
Photometric characterization of a well defined sample of isolated galaxies in the context of the AMIGA project
A. Durbala, J. W. Sulentic, R. Buta +1
We perform a detailed photometric analysis (bulge-disk-bar decomposition and Concentration-Asymmetry-Clumpiness - CAS parametrization) for a well defined sample of isolated galaxie…
Hydrodynamical Simulations of the Barred Spiral Galaxy NGC 6782
Lien-Hsuan Lin, Chi Yuan, R. Buta
NGC 6782 is an early-type barred spiral galaxy exhibiting a rich and complex morphology with multiple ring patterns. To provide a physical understanding of its structure and kinema…
