Her Ph.D. research was on young star clusters and ga lactic chemical evolution. She was a postdoc at the University of Arizona where she spent as much time as possible at telescopes gathering data on galactic winds. In 2009\, Dr. Tremonti began her appointment as an assist ant professor at the University of Wisconsin-Madison where she is continui ng to do research on the astrophysics of galactic winds. More information on her research can be found at http://www.astro.wisc.edu/our-people/facu lty/tremonti/\n\n\nAbstract\n\nA key question in galaxy evolution is how t he formation of stars is regulated. Stars form out of cold gas\, but th e most massive stars and their subsequent supernovae supply energy and mom entum to the surrounding gas that make it more difficult for subsequent ge nerations of stars to form. In galaxies with very high star formation ra tes\, the collective impact of these ‘feedback’ process can be extreme with gas being ejected out of the galaxies in spectacular outflows called ‘galactic winds’. In this talk\, I will discuss the physics underp inning the driving of galactic winds and I will present some new observati ons of a sample of compact massive starbursts that are driving the fastest winds yet observed. One surprising feature of these outflows is that the y contain cool ionized and molecular gas moving at velocities of ~2000 km/ s. I will conclude by evaluating some recent ideas for accelerating cold gas to these velocities without destroying it.\n\n SUMMARY;LANGUAGE=en-US:Live zoom colloquium (3-2) - Oct 1 (Thursday) 4 PM - Physics and Astronomy Colloquium DTSTART;TZID=Central Standard Time:20201001T160000 DTEND;TZID=Central Standard Time:20201001T170000 UID:040000008200E00074C5B7101A82E00800000000D593A4EF8596D601000000000000000 0100000008B706DFF35C99A419FB7BCF37553D3F2 CLASS:PUBLIC PRIORITY:5 DTSTAMP:20200929T220703Z TRANSP:OPAQUE STATUS:CONFIRMED SEQUENCE:4 LOCATION;LANGUAGE=en-US:Zoom online X-MICROSOFT-CDO-APPT-SEQUENCE:4 X-MICROSOFT-CDO-OWNERAPPTID:2118772949 X-MICROSOFT-CDO-BUSYSTATUS:TENTATIVE X-MICROSOFT-CDO-INTENDEDSTATUS:BUSY X-MICROSOFT-CDO-ALLDAYEVENT:FALSE X-MICROSOFT-CDO-IMPORTANCE:1 X-MICROSOFT-CDO-INSTTYPE:0 X-MICROSOFT-DISALLOW-COUNTER:FALSE BEGIN:VALARM ACTION:DISPLAY DESCRIPTION:REMINDER TRIGGER;RELATED=START:-PT30M END:VALARM END:VEVENT END:VCALENDAR
