Gemini GMOS spectroscopy of HeII nebulae in M33
stars atmospheres — stars Wolf-Rayet — ISM HII regions — ISM lines and bands — galaxies individual (M33)—galaxies
2010/11/15
We have carried out a narrow-band survey of the Local Group galaxy, M33, in the HeII λ4686 emission line, to identify HeII nebulae in this galaxy. With spectroscopic follow-up observations, we confirm...
Comparison of AGN and Nuclear Starburst Activity in Seyfert 1 and 2 Galaxies over a Wide Luminosity Range Based on Near-infrared 2-4 micrometer Spectroscopy
Galaxy Astrophysics (astro-ph.GA)
2011/1/4
We present near-infrared K- (1.9-2.5 micrometer) and L- (2.8-4.2 micrometer) band spectroscopy of 22 Seyfert nuclei. We use two methods to investigate the presence of nuclear starbursts.
Gemini/GMOS Spectroscopy of 26 Strong Lensing Selected Galaxy Cluster Cores
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/4
We present results from a spectroscopic program targeting 26 strong lensing cluster cores that were visually identified in the Sloan Digital Sky Survey (SDSS) and the Second Red-Sequence Cluster Surve...
