 Title: METHANOL AT THE EDGE OF THE GALAXY: NEW OBSERVATIONS TO CONSTRAIN THE GALACTIC HABITABLE ZONE Author(s): Bernal, Jacob Contributor(s): Sephus, Cathryn ; Ziurys, Lucy M. Subject(s): Astronomy Abstract: Searches have been conducted for the J=2-1 transitions of methanol at 3mm in a sample of molecular clouds located 13-23.5 kpc from the Galactic Center, using the ARO 12m telescope. The sources are in the Cygnus arms, and typically are cold with T$_{K}$ approximately 20 K. Multiple transitions of this organic molecule were detected in 19 clouds, including ones at distances of approximately 23.5 kpc. Typical abundances found for methanol are 1x10$^{9}$. The results suggest that the Galactic Habitable Zone (GHZ) may exist much further from the Galactic Center than previously thought.
