... We find that HRТљ4049 shows remarkable structure in the major bands (3.3, 6.2, '7.7', 8.6 and 11.3 m) and probably has small, ionized, hydrogen-rich and highly excited PAHs. ...

... There is also a thermal component which arises from free-free emission from ionizedhydrogen in HII regions, but this contributes only 10% of the radio emission at lower frequencies (<5 GHz, Condon 1992), and becomes more significant at higher frequencies ...
... The heavily obscured compact nuclear starburst model predicts that line emission from ionizedhydrogen should be powerful and characteristically concentrated within the central kpc-scale nuclear region. ...
... fluctuations in the distribution of galaxies contributed to a scatter in the ionizing background, and hence in the ionization fraction of cosmic hydrogen on scales of tens of Mpc, as observed along the lines of sight to the earliest known quasars ...
