The Spectra of Star Forming Galaxiesat High
We review the spectral properties of the population of star forming galaxies at z 3 discovered using a colour selection technique which targets the Lyman discontinuity at 912 A. The UV luminosity of the typical z 3 galaxy exceeds by more than one order of magnitude that of the most luminous starbursts in the nearby universe, although the maximum star formation intensity (SFR per unit area) is w...
متن کاملSoft Particle Spectra at STAR Zhangbu Xu for the STAR Collaboration
We presented the multiplicity and the spectra of many particles in Au+Au at √ s N N = 130 GeV measured by STAR detector. Their connections to initial condition, baryon creation, freeze-out condition and strangeness enhancement were discussed. In relativistic heavy ion collisions at RHIC, thousands of particles of different properties are created. Although interactions with very high momentum tr...

متن کاملRosetta-Alice calibration star reference spectra: Selection and correction
Calibration of the effective area (Aeff) for the Rosetta-Alice instrument requires observation of calibration stars with known FUV spectra. A number of calibration stars have been selected and observed for this purpose, and will continue to be observed in future mission phases. Calibrated spectra of the same stars from past and current FUV missions constitute the known spectra against which R-A...
متن کاملStar-Forming Regions Derived from Spitzer IRS Spectra
Using Spitzer Infrared Spectrograph observations of G0–M4 III stars behind dark clouds, I construct 5− 20μm empirical extinction curves for 0.3 ≤ AK < 7, which is equivalent to AV between ≈ 3 and 50. For AK < 1 the curve appears similar to the Mathis (1990) diffuse interstellar medium extinction curve, but with a greater degree of extinction. For AK > 1, the cuve exhibits lower contrast between...
