Snorkelling between the stars: submarine methods for astronomical observations.
Trying to reach diffraction-limited astronomical observations from ground-based telescopes is very challenging due to the atmospheric effects contributing to a...
Certain results of observational cosmology cast critical doubt on the foundations of standard cosmology but leave most cosmologists untroubled. Alternative...
SOFIA observations of the planetary nebula NGC 7009
We report spectrophotometric observations made with SOFIA/FORCAST on 2011 June 2 UT. Optical measurements have previously shown that the abundance discrepancy...
Soft X-ray to Far Infrared luminosities ratio in star-forming galaxies
A good correlation has been found in star-forming galaxies between the soft X-ray and the far infrared or radio luminosities. In this work we analyze the...
Soft X-Ray Transient Light Curves as Standard Candles: Exponential Versus Linear Decays
A recent paper by King & Ritter (KR) proposed that the light curves of Soft X-ray Transients (SXTs) are dominated by the effect of irradiation of the accretion...
