I am looking for a brief summary of current hydrogen detection within galaxies.
How are H I and H II detected? Is there a minimum required temperature and/or density ?
How is molecular hydrogen detected? Is this the only form of hydrogen with sufficient density that can become opaque thereby creating Bok globules?
Gas to gas, Doug Ettinger
