Scientists discover clues to ancient high sea level rise in Mallorcan cave（图）
Scientists ancient high sea level rise Mallorcan cave
2019/10/18
Scientists studying evidence preserved in a coastal cave have shown that more than three million years ago -- a time in which Earth was two to three degrees Celsius warmer than the pre-industrial era ...
Chandra Observations of the Bursting X-Ray Transient SAX J1747.0–2853 during Low-Level Accretion Activity
SAX J1747.0–2853 stars
2014/12/26
We present Chandra/ACIS observations of the bursting X-ray transient SAX J1747.0-2853 performed on 2001 July 18. We detected a bright source at the position of R.A. = 17h47m02.s60 and decl. = -28°52'5...
Setting the Normalcy Level of HI Properties in Isolated Galaxies
atomic gas local Universe
2014/12/20
Studying the atomic gas (HI) properties of the most isolated galaxies is essential to quantify the effect that the environment exerts on this sensitive component of the interstellar medium. We observe...
Accurate relative spectrophotometry is critical for many science applications. Small wavelength scale residuals in the flux calibration can significantly impact the measurements of weak emission and a...
Far-Infrared to Millimeter Astrophysical Dust Emission. II: Comparison of the Two-Level Systems (TLS) model with Astronomical Data
Far-Infrared Millimeter Astrophysical Dust Emission Comparison model Astronomical Data
2011/10/20
In a previous paper we proposed a new model for the emission by amorphous astronomical dust grains, based on solid-state physics. The model uses a description of the Disordered Charge Distribution (DC...
Changes in Sea-Level Pressure over South Korea Associated with High-Speed Solar Wind Events
solar-terrestrial weather sea-level pressure solar wind
2011/9/30
We explore a possibility that the daily sea-level pressure (SLP) over South Korea responds to the high-speed solar wind event. This is of interest in two aspects: First, if there is a statistical asso...
Confidence Level Estimator for cosmological model
Confidence Level Estimator cosmological model
2011/1/13
Models of the Universe like the Concordance Model today used to interpret cosmological observations give expectation values for many cosmological observable so accurate that frequently peoples speak o...
Venus wind map at cloud top level with the MTR/THEMIS visible spectrometer. I. Instrumental performance and first results
Venus Wind Clouds Visible Spectrometry
2010/11/15
Solar light gets scattered at cloud top level in Venus’ atmosphere, in the visible range, which corresponds to the altitude of 67 km. We present Doppler velocity measurements performed with the high r...
