DESCRIPTION:Event Title: Assaying the Atmospheres That Milky Ways Breathe w

 sity Event Details / Abstract: Galaxies grow and quench by exchanging gas 
 and energy with their circumgalactic medium (CGM)\, the diffuse atmosphere
 s that fuel star formation and absorb feedback. In this talk I trace this 
 exchange in three parts. First\, I revisit scaling relations among stellar
  mass\, size\, star formation rate (SFR)\, and gas across cosmic time\, in
 cluding new JWST results on the SFR surface density sequence and associate
 d selection effects. Next\, I present recent work with the Circumgalactic 
 Hα Spectrograph (CHaS)\, a narrowband integral field spectrograph (R~10\,
 000) we built for the MDM Observatory on Kitt Peak to map faint Hα emissi
 on from the CGM of nearby galaxies. These maps reveal complex halo dynamic
 s. Looking ahead\, CHaS will continue to target the Local Sheet\, where co
 nstrained Local Group simulations suggest that our…\n\nhttps://localz.ev
