We present a Chandra observation of the globular cluster Terzan 5 during times when the neutron star X-ray transient EXO 1745—248 located in this cluster was in its quiescent state. We detected the quiescent system with a (0.5-10 keV) luminosity of ～2 x 10~(33) ergs s~(-1). This...

Moreover, the energy spectrum measured by LHAASO challenges the standard radiation model of GRB afterglows, revealing that the intensity of cosmic background light in the infrared band is lower than expected. This prompts a reevaluation of the formation and evolution of galaxies in the universe, a...
The dsp.SpectrumEstimator System object™ computes the power spectrum or the power density spectrum of a signal using the Welch algorithm or the filter bank approach. When you choose the Welch method, the object computes the averaged modified periodograms to compute the spectral estimate. When ...

We present results from a short series of blue, moderate resolution spectra of the microquasar binary, SS 433. The observations were made at a time optimized to find the spectrum of the donor star, i.e., when the donor was in the foreground and well above the plane of the obscuring dis...
The spectrum of HD46223 来自 arXiv.org 喜欢 0 阅读量: 97 作者: Zagury, Frederic 摘要: The spectrum of HD46223 was established from the optical to the far UV and normalized by the spectrum of a non-reddened star of same spectral type. The resulting spectrum is separated into two ...

Gamma-ray bursts (GRBs) and their afterglows have been proposed as an excellent probe to study the evolution of cosmic star formation, the reionization of the intergalactic medium, and the metal enrichment history of the universe, since the prompt gamma-ray emission of GRBs should be detectable...
