[O II] as a tracer of current star formation
Rolf A. Jansen, Marijn Franx, Daniel Fabricant
[O II] lambda 3727 Angstrom is often used as a tracer of star formation at intermediate redshifts (z > 0.4), where Halpha is not easily observed. We use the spectrophotometric data…
BeppoSAX study of the broad-band properties of luminous globular cluster X-ray sources
L. Sidoli, A. N. Parmar, T. Oosterbroek +4
We have performed a detailed study of the broadband spectra of the luminous globular cluster X-ray sources using BeppoSAX. With the exception of X2127+119, located in NGC7078, all…
X-ray emission in the direction of the SNR G318.2+0.1
F. Bocchino, A. N. Parmar, S. Mereghetti +3
We report the discovery of three X-ray sources within the radio shell G318.2+0.1, one of which may be extended. Two of the sources were detected during the \sax Galactic Plane Surv…
The Optical-Near-IR Spectrum of the M87 Jet From HST Observations
Eric S. Perlman, John Biretta, William Sparks +2
We present 1998 HST observations of M87 which yield the first single-epoch optical and radio-optical spectral index images of the jet at resolution. We find $<α_{ro} > \ap…
Stellar Coronae with \textit{XMM-Newton} RGS. II. X-ray Variability
M. Audard, M. Guedel, A. J. den Boggende +16
First results from high-resolution coronal spectroscopy of flares with the Reflection Grating Spectrometers on board the \textit{XMM-Newton} satellite are reviewed. Rotational modu…
Stellar Coronae with \textit{XMM-Newton} RGS. I. Coronal Structure
M. Guedel, M. Audard, A. J. den Boggende +16
First results from high-resolution coronal spectroscopy with the {\it XMM-Newton} Reflection Grating Spectrometers (RGS) are reviewed. Five stellar systems (HR 1099, Capella, Procy…
