Nuclear Rings in Galaxies---A Kinematic Perspective
Nuclear Rings Galaxies---A Kinematic Perspective
2011/10/19
We combine DensePak integral field unit and TAURUS Fabry-Perot observations of 13 nuclear rings to show an interconnection between the kinematic properties of the rings and their resonant origin. The ...
GRIPS and the Perspective of Next-generation Gamma-ray Surveys
GRIPS Perspective Next-generation Gamma-ray Surveys
2011/10/19
GRIPS is one example of next generation telescopes proposed for astronomy the energy range between hard X-ray mirror instruments such as NuStar and the Fermi telescope. The Compton telescope principle...
Solar-like Oscillations: An Observational Perspective
Solar-like Oscillations Observational Perspective
2011/9/30
Solar-like oscillations are excited stochastically by convection. They occur in stars with an outer convection zone, which includes the Sun and other stars on the lower main sequence, as well as cool ...
Astrophysics and cosmology with galaxy clusters: the WFXT perspective
Astrophysics cosmology galaxy clusters
2011/1/13
We discuss the central role played by the X-ray study of hot baryons within galaxy clusters to reconstruct the assembly of cosmic structures and to trace the past history of star formation and accret...
A Radio Perspective on the Wet Merger Remnant NGC 34
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
We present VLA observations of the neutral hydrogen and radio continuum of NGC 34 (= NGC 17 = Mrk 938). This object is an ideal candidate to study the fate of gas in mergers, since, as shown by an opt...
Transient Perturbations and their Effects in the Heliosphere, the Geomagnetosphere, and the Earth’s Atmosphere: Space Weather Perspective
Space weather geomagnetic storm cosmic ray Forbush decrease interplanetary shock coronal mass ejection
2010/9/16
We discuss the effects of certain dynamic features of space environment in the heliosphere, the geo-magnetosphere, and the earth’s atmosphere. In particular, transient perturbations in solar wind plas...
