The effect of feedback on the emission properties of the Warm-Hot Intergalactic Medium
feedback emission properties the Warm-Hot Intergalactic Medium
2012/2/21
At present, 30-40 per cent of the baryons in the local Universe is still undetected. According to theoretical predictions, this gas should reside in filaments filling the large-scale structure (LSS) i...
Faint Extended OH Emission from the Local Interstellar Medium in the Direction l \approx 108\circ, b \approx 5\circ
OH Emission Local Interstellar Medium Cosmology and Extragalactic Astrophysics
2012/2/21
We have mapped faint 1667 OH line emission (TA \approx 20 - 40 mK in our \approx 30' beam) along many lines of sight in the Galaxy covering an area of \approx 4\circ \times 4\circ in the general direc...
Determination of the Mean HI Absorption of the Intergalactic Medium
Quasar absorption lines—galaxies intergalactic medium
2010/9/15
In recent years, the Lyman-α forest in quasar spectra has been used, together with N-body simulations, to determine the underlying matter distribution in the intergalactic medium (IGM). One of the key...
