The Structure of the Inner HH 34 Jet from Optical Integral Field Spectroscopy
Tracy L. Beck, A. Riera, A. C. Raga +1
We present high spatial resolution optical integral field spectroscopy of a collimated Herbig-Haro jet viewed nearly edge-on. Maps of the line emission, velocity centroid, and velo…
O VI and H_2 Lines in Sunspots
Nicolas Labrosse, Huw Morgan, Shadia Rifai Habbal +1
Sunspots are locations on the Sun where unique atmospheric conditions prevail. In particular, the very low temperatures found above sunspots allow the emission of H_2 lines. In thi…
Warm-Hot Intergalactic Medium Associated with the Coma Cluster
Yoh Takei, J. Patrick Henry, Alexis Finoguenov +4
We present our XMM-Newton RGS observations of X Comae, an AGN behind the Coma cluster. We detect absorption by NeIX and OVIII at the redshift of Coma with an equivalent width of 3.…
First Detection of NaI D lines in High-Redshift Damped Lyman-alpha Systems
Sohei Kondo, Naoto Kobayashi, Yosuke Minowa +15
A Near-infrared (1.18-1.35 micron) high-resolution spectrum of the gravitationally-lensed QSO APM 08279+5255 was obtained with the IRCS mounted on the Subaru Telescope using the AO…
Optical and infrared observations of the Type IIP SN2002hh from day 3 to 397
M. Pozzo, W. P. S. Meikle, J. T. Rayner +6
We present optical and infrared (IR) observations of the type IIP SN2002hh from 3 to 397 days after explosion. The optical spectroscopic (4-397d) and photometric (3-278d) data are…
