The temperature of the low-density intergalactic medium is set by the balance between adiabatic cooling resulting from the expansion of the universe, and photo-heating by the UV-background. A sudden injection of entropy from the reionization will increase the temperature of the gas, leading to a broadening of the hydrogen Lyman-α absorption lines produced in the IGM, and observed in the spectra...

Lyα forests are usually associated with intergalactic gas clouds intercepting the quasar sight–line. Using as an example the Lyα forest of QSO 0055–26 (zem = 3.66), we show that the probability of observing a line at the velocity difference ∆v has an intermittent structure in the redshift space. On small scales (70 km s ≤ ∆v ≤ 1580 km s) the signature of intermittency appears as a self–similar ...

Abstract Introduction American Indian/Alaska Native (AI/AN) individuals experience health disparities that emerge early in life. This is the first study to prospectively examine associations between sleep and daily behaviors urban AI/AN adolescents. Methods Participants were 142 adolescents (mean age = 14 years, 58% female). Sleep characteristics measured with actigraphy (total time [TST], effi...

An XMM-Newton target of opportunity observation of the field around the transient 18.37 s pulsar XTE J0055−727 in the Small Magellanic Cloud (SMC) revealed two bright, long-period X-ray pulsars in the EPIC data. A new pulsar, XMMU J005517.9−723853, with a pulse period of 701.7 ± 0.8 s was discovered and 500.0 ± 0.2 s pulsations were detected from XMMU J005455.4−724512 (= CXOU J005455.6−724510),...
