1. STScI Preprint #1330
... Blazar spectral energy distributions (SEDs) are double peaked and follow a self-similar sequence in luminosity. The so-called "blue" blazars, whose first SED component peaks at X-ray energies, are TeV sources, although with a relatively small fraction of their bolometric luminosities. The "red" blazars, with SED peaks in the infrared-optical range, appear to emit relatively more power in the gamma-ray component but at much lower energies (GeV and below). ... toolan@stsci.edu . ...

ASTR1001 "Astrophysics" Assignment 3. ... Due to persistent nagging from the science team, Captain Chubb eventually relented and sent a stealthy robot probe in close to take pictures. The probe got to 500 AU out, and took one close up picture of the dot. ... No further data were taken. ... The dot actually consists of two objects, a large one (component A) and a small one (component B). ... The luminosity of the two components could be measured from the image at three wavelengths. ...

... Однако это только незначительная часть (~ 3*10 -9 ) жизни Галактики, доступной для современного SETI. Поиск отдельных метеоритов-артефактов, накапливаемых Землей, может покрыть полную историю жизни Галактики. ... Межзвездные артефакты могут быть разрушены в атмосфере планеты, но часть из них может сохраниться. ... Следует отметить, что по-мнению автора, данные оценки могут служить свидетельством о том, что происхождение жизни на Земле может быть связано с падением подобных метеоритов-артефактов. ...
