SUMMARY:"The Internal Structure of Interstellar Filaments in the South
 ern Milky Way" \, Astronomy Colloquium\, Audra Hernandez\, UW Madison 
 Astronomy Dept
DESCRIPTION:Is all Galactic star formation concentrated within filamen
 tary structures inside molecular clouds?  High resolution observations
  have shown that filamentary interstellar clouds are ubiquitous throug
 hout the interstellar medium. These filaments exist over a range of sp
 atial scales\, from parsec regions containing young stellar activity\,
  to the multi-parsec scales of giant molecular clouds. Although infrar
 ed observations have provided high-resolution images of star-forming c
 louds\, they are limited by their two-dimensional nature.  The only wa
 y to assess the kinematical natures of thee filaments is through spect
 roscopic radio observations.  While it is clear that stars form within
  the desist regions of the interstellar medium\, one of the main goals
  of modern astrophysics is to understand how the properties of interst
 ellar filaments influence the star-formation process.  I will begin wi
 th a review of the recent and exciting studies on multi-scale molecula
 r filaments.  Finally\, I will discuss my ongoing research on probing 
 the internal structure of interstellar molecular filaments within the 
 Southern Galactic plane with recent multi-line large-scale spectroscop
 ic molecular surveys.
