Accretion, feedback and galaxy bimodality: a comparison of the GalICS semi-analytic model and cosmological SPH simulations
cooling fl ows evolution
2014/12/23
We compare the galaxy population of a smoothed particle hydrodynamics (SPH) simulation to those predicted by the GalICS (Galaxies In Cosmological Simulations) N-body + semi-analytic model and a stripp...
Galaxy evolution in groups and clusters: star formation rates, red sequence fractions, and the persistent bimodality
methods: statistical-galaxies: groups: general-galaxies: clusters:general-galaxies: haloes-galaxies: evolution-galaxies: star formation
2011/10/17
Using galaxy group/cluster catalogs created from the Sloan Digital Sky Survey Data Release 7, we examine in detail the specific star formation rate (SSFR) distribution of satellite galaxies and its de...
Spectra of globular clusters in the Sombrero galaxy: evidence for spectroscopic metallicity bimodality
globular clusters: general galaxies: individual: Sombrero (M104: NGC4594) galaxies: star clusters
2011/9/28
We present a large sample of over 200 integrated-light spectra of confirmed globular clusters (GCs) associated with the Sombrero (M104) galaxy taken with the DEIMOS instrument on the Keck telescope. A...
Comparison of the VIMOS-VLT Deep Survey with the Munich semi-analytical model - I. Magnitude counts, redshift distribution, colour bimodality, and galaxy clustering
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/23
This paper presents a detailed comparison between high-redshift observations from the VIMOS-VLT Deep Survey (VVDS) and predictions from the Munich semi-analytical model of galaxy formation.
A barotropic ocean model is used to study the bimodal behavior of the Kuroshio to the south of Japan. By considering the combined effects of the beta plane, the Kyushu coastal perturbation, the Izu Ri...
Kuroshio Path Variations South of Japan: Bimodality as a Self-Sustained Internal Oscillation
Kuroshio Path South of Japan Self-Sustained Internal Oscillation
2008/7/2
In the two decades following 1975, the Kuroshio path south of Japan was observed to oscillate interannually between a straight path state and a meandering state. This bimodal condition is in sharp con...
