Gas Filaments Between Galaxies

Incomplete! Notes will expand as I puzzle my way through the papers.

• Missing baryons in the cosmic web revealed by the Sunyaev-Zel'dovich effect
• Anna de Graaff, Yan-Chuan Cai, Catherine Heymans, John A. Peacock

Can account for 30% of the total baryon content of the universe. The Sunyaev-Zel'dovich effect is the Compton scattering of the Cosmic Microwave Background (CMB), so its effects can be inferred from Planck space telescope data.

• A Search for Warm/Hot Gas Filaments Between Pairs of SDSS Luminous Red Galaxies

• Hideki Tanimura, Gary Hinshaw, Ian G. McCarthy, Ludovic Van Waerbeke, Yin-Zhe Ma, Alexander Mead, Alireza Hojjati, Tilman Tröster

Hubble dimensionless constant h is around 0.7, which means the Hubble constant Ho is around 70 (km/s)/Mpc . A fudge factor to compensate for differing measurements and opinions.
