The State of the Gas and the Relation Between Gas and Star Formation at Low Metallicity: the Small Magellanic Cloud
State Relation Between Gas Star Formation Metallicity: Magellanic Cloud
2011/9/30
We compare atomic gas, molecular gas, and the recent star formation rate (SFR) inferred from H-alpha in the Small Magellanic Cloud (SMC). By using infrared dust emission and local dust-to-gas ratios, ...

A correlation between redshifts .z/ and apparent magnitudes
.V / (Hubble relation) of Quasi Stellar Objects (QSOs) has long been
sought. Such a correlation exists for galaxies whose redshifts are of...
