2008年，科学家们开始对APM08279+5255类星体进行研究。经过长达6年的观察，利用光谱分析技术，科学家们发现了大量的声波信号图样，这些信号最终被确定为氢氧结合发出的波效应。这一发现震惊了科学界，因为APM08279+5255类星体中的含水量达到了惊人的14亿亿立方千米，是地球海洋含水量的140万倍。APM08279+5255类星体的...
We present Keck high-resolution near-IR (2.2 microns; FWHM~0.15") and mid-IR (12.5 microns; FWHM~0.4") images of APM08279+5255, a z=3.91 IR-luminous BALQSO with a prodigious apparent bolometric luminosity of 5x10^{15} Lsun, the largest known in the universe. The K-band image shows...
APM 08279+5255是宇宙中最大的水库,水量是地球水量的100万亿倍 APM 08279+5255可能是宇宙中最明亮的天体,这一方面是它自身的亮度非常高,第二个原因是它是一个引力透镜物体,所以从地球上观测的话,APM 08279+5255的亮度就会被放大了。其亮度达到了太阳亮度的10万亿~100万亿倍。 APM 08279+5255的核心是一个超大质量...
APM 08279+5255 - An Ultraluminous BAL Quasar at z=3.87? During a survey for distant carbon stars in the Galactic Halo we discovered an extremely bright, R=15.2 broad absorption line quasar at a redshift of z=3.87. The quasar is positionally coincident, within a few arcsec, with the IRAS...

We have re-analyzed the X-ray spectra of the gravitational lensed high-redshift BAL QSO APM 08279+5255, observed with the XMM-Newton and Chandra observatories. Previous studies (Hasinger et al. 2002, ApJ, 573, L77; Chartas et al. 2002, ApJ, 579, 169) detected unusual, highly-ionized...

The viability of two different classes of \Lambda(t) \Lambda(t) CDM cosmologies is tested by using the APM 08279+5255, an old quasar at redshift z = 3.91 z = 3.91 . In the first class of models, the cosmological term scales as \Lambda(t)\sim R^{-n} \Lambda(t)\sim R^{-n}...
