Investigating the long-term evolution of galaxies: Noise, cuspy halos and bars
cuspy halos bars
2014/12/26
I review the arguments for the importance of halo structure in driving galaxy evolution and coupling a galaxy to its environment. We begin with a general discussion of the key dynamics and examples of...
The long-term millimeter activity of active galactic nuclei
Galaxies: active — Quasars: general — Radiation mechanisms: non-thermal
2011/10/18
We analyze the long-term evolution of the fluxes of six active galactic nuclei (AGN) - 0923+392, 3C 111, 3C 273, 3C 345, 3C 454.3, and 3C 84 - in the frequency range 80-267 GHz using archival calibrat...
Long-term evolution of massive black hole binaries. IV. Mergers of galaxies with collisionally relaxed nuclei
large-scale structure of Universe – cosmology: theory – cosmology: observations – cosmological parameters
2011/10/12
We simulate mergers between galaxies containing collisionally-relaxed nuclei around massive black holes (MBHs). Our galaxies contain four mass groups, representative of old stellar populations; a prim...

Long-term Modulation of Cosmic Ray Intensity in relation to Sunspot Numbers and Tilt Angle
Cosmic ray intensity sunspot numbers tilt angle
2009/5/7
Adetailed correlative analysis between sunspot numbers (SSN) and tilt angle (TA) with cosmic ray intensity (CRI) in the neutron monitor energy range has been performed for the solar cycles 21, 22 and ...
