Arp 220 and "The Big Bang Theory" TV show

    There are usually scientific equations on the whiteboards, and finally I recognized something that I understood. Arp 220 featured In "The Closure Alternative" 2013 of the "The Big Bang Theory" TV series
    Raj is an astrophysics, and in his office there are two whiteboards

    I can't read the numbers well, it wasn't in HD.

    STF is star formation rate

    http://en.wikipedia.org/wiki/Arp_220 Wiki has information and links to recent galaxy formation, high rate of star formation, presence of some organix molecules, and a water maser.

    Maybe something like this article? Water Vapor in nearby Infrared Galaxies as Probed by Herschel

    A forum post about Arp220 containing lots of information about radio wave astronomy and dust in galaxies, by EigenState

    Forum: Sunday, 24 July 2011: Arp 220: Dust and Molecular Gas by EigenState http://www.galaxyzooforum.org/index.php?topic=279339.0 " bright central region is a glowing cloud of exceedingly hot (» 106 K) gas rushing out of the galaxy, driven by a "superwind" presumed to result from explosive activity generated by the formation of hundreds of millions of new stars...spectrum of Arp 220 [2] observed over the range of 200 to 700 μm (1500 to 427 GHz) shows strong emission features from pure rotational transitions of CO and H2O; high rotational transitions of HCN in absorption; rotational transitions of the rare molecules OH+, H2O+, and HF in absorption; as well as electric-quadrupole allowed, fine structure transitions within the ground electronic states of the atomic species [CI] and [NII]"
