Magnetic Fields, Relativistic Particles, and Shock Waves in Cluster Outskirts
Magnetic Fields Relativistic Particles Shock Waves Cluster Outskirts
2011/10/20
It is only now, with low-frequency radio telescopes, long exposures with high-resolution X-ray satellites and gamma-ray telescopes, that we are beginning to learn about the physics in the periphery of...
Evidence for crust cooling in the transiently accreting 11-Hz X-ray pulsar in the globular cluster Terzan 5
globular clusters: individual (Terzan 5) - X-rays: binaries - stars: neutron -pulsars: individual (CXOGClb J174804.8–244648, IGR J17480–2446)

The temporal heating and subsequent cooling of the crusts of transiently accreting neutron stars carries unique information about their structure and a variety of nuclear reaction processes. We report...
A Spitzer IRS Survey of NGC 1333: Insights into disk evolution from a very young cluster
Spitzer IRS Survey Insights evolution cluster
2011/10/10
We report on the {\lambda} = 5-36{\mu}m Spitzer Infrared Spectrograph spectra of 79 young stellar objects in the very young nearby cluster NGC 1333. NGC 1333's youth enables the study of early protopl...
First observations of CN(2-1), HCO$^{+}$(3-2) and C$_{2}$H(3-2) emission lines in the Perseus cluster: constraints on heating mechanisms in the cluster gas

We present the first observations of emission lines of CN(2-1), HCO$^{+}$(3-2) and C$_{2}$H(3-2) in the Perseus cluster. We observed at two positions: directly at the central galaxy, NGC 1275 and also...
The bright end of the colour-magnitude relation of cluster galaxies
galaxies: clusters: general - galaxies: formation - galaxies: evolution
2011/9/27
We investigate the development of the red sequence (RS) of cluster galaxies by using a semi-analytic model of galaxy formation. Results show good agreement between the general trend of the simulated R...
